Description

  The present disclosure generally relates to modular lighting devices and methods for assembling, mounting and replacing such devices. In various aspects, the methods and apparatus disclosed by the present application facilitate the manufacture, installation, and replacement of modular lighting device components and improve thermal efficiency during operation. In one aspect, such lighting devices and methods use LED-based light sources to provide visible light for a variety of lighting applications in a variety of environments.

  LED-based lighting fixtures are used in a variety of lighting applications. In some cases, the lighting fixture includes a controller, one or more LED-based light sources in one built-in unit, and one or more components to further promote heat dissipation. May be included. Replacing any one element of such a built-in unit requires replacing the entire lighting fixture or repairing by a skilled technician. Furthermore, if a different LED-based lighting assembly is desired or if the existing LED-based source (s) fails, it may be difficult to physically replace the new LED-based light source with the existing LED-based light source. There is a possibility.

  Recessed lighting is a popular lighting option for both new construction and renovation. In recessed lighting, the majority of lighting fixtures are substantially located behind or embedded in a building surface or structure such as a ceiling (or wall, or soffit) . Lighting fixtures typically include a housing (sometimes commonly referred to as a “can”), an incandescent bulb, a fluorescent or halogen bulb, and some means of electrically connecting the fixture to an operating power source. including. In new construction, the fixture is typically supported by hangers attached to joists. During renovations, fixtures may be attached to a drywall that is inserted through the ceiling hole to form the ceiling to reduce the amount of ceiling (or other building surface) that is removed. In some cases, the ceiling hole becomes a light emitting opening for the light generated by the fixture bulb.

  Various aspects of the disclosure according to the present invention provide a modular lighting installation that allows for easy installation and removal of a controller module that may be used to control the light generation module in addition to the LED-based light generation module. Intended for ingredients. In one example, the modular lighting fixture is configured to be embedded in or otherwise placed behind a building surface, such as a ceiling, wall, or sofit, in a new or renovation plan. Including housing. The fixture housing includes a socket configured to facilitate one or more of mechanical, electrical, or thermal coupling of the light generating module to the fixture housing. The ability to easily engage or disengage the LED-based light generation module and socket without removing the fixture housing itself, allowing easy and clear replacement of the light generation module in case of failure, or another module with different light generation characteristics Exchange with is possible. Such modular lighting controllers (also referred to as “controller modules”) can also be easily installed and removed from the fixture housing, sometimes via the same access path as installing and removing the light generating module. it can.

  Thus, according to various aspects of the present disclosure, a modular lighting fixture is provided in which a single housing can accommodate different LED-based light generation modules that can be switched in and out of the housing. The In this respect, the light generation module according to various aspects of the disclosure of the present invention is a conventional incandescent lamp and fluorescent lamp in that a new light generation module can be inserted into the housing without changing to the fixture. Or you can simulate the ease of installation and replacement of halogen lamps. A new light generation module can be inserted, for example, when the previous light generation module fails or when an improved or heterogeneous light generation module is desired.

  As described above, according to one aspect of the present disclosure, a socket or other mounting element facilitates mounting a light generating module to a lighting fixture housing. In addition to the mechanical connection between the light generation module and the lighting fixture, the socket can also provide an electrical connection and / or a thermal connection. For example, the socket may include an electrical connection that provides drive signals and operating power to the light generation module when the light generation module is inserted into the socket or otherwise coupled thereto. . According to another aspect of the present disclosure, a socket or other attachment element can promote thermal diffusion in at least two ways. First, the socket may be configured to interact with the light generation module such that the light generation module achieves a thermal connection with the housing or other components of the lighting fixture. Second, the socket itself is thermally conductive to facilitate heat transfer to the housing and / or heat transfer directly to the ambient air (eg, via the light emitting surface in front of the light generating module). May be.

  According to another aspect of the present disclosure, the removable light generation module is itself configured to facilitate heat transfer outward from the light source within the module. This heat transfer is achieved in some embodiments by using a thermally conductive chassis for the light generating module to facilitate heat transfer from the front side (light emitting surface) of the light generating module. In some embodiments, a thermally conductive base plate is attached to the back side of the light generating module to facilitate heat transfer to the lighting fixture housing or other components, possibly via a socket.

  According to another aspect of the disclosure according to the present invention, engagement and disengagement of the light generating module and the socket of the lighting fixture is accomplished by a simple rotational movement. In this regard, the attachment and removal of the LED-based light generation module from the modular lighting fixture can provide a familiar sensation similar to the process of replacing a conventional incandescent bulb.

  In particular, in one exemplary embodiment, the socket is configured as a collar with threaded threads, and the module is disposed on the module and engages with the threads on the socket by rotation. Via a threaded grip ring, it is configured to be detachable from the socket, whereby the module is “sandwiched” between the grip ring and the socket. According to another aspect of the present disclosure, a removable light generation module includes a number of hexagonal LED subassemblies. In some aspects, the grip is rotatable with respect to the module so that the orientation of the LED subassembly is not affected by the rotation of the grip ring (ie, when the grip ring is rotated, the module itself is Does not rotate in the socket). Furthermore, the relative rotation of the grip ring makes it possible to attach the connector directly to the light generating module without worrying about the effect of twisting on the connector.

  In other embodiments, the grip ring is not used to secure the light generating module to the socket, and the electrical connection between the light generating module and the socket is a post (or screw) on the light generating module. This is achieved through a connection between the thread) and the corresponding thread (or post) on the socket. That is, in some embodiments, electrical contacts may be provided on the engagement element itself.

  According to another aspect of the disclosure according to the present invention, in an example of one aspect of a lighting fixture, the controller module may be used in connection with a light generation module. According to another aspect of the present disclosure, the controller module may have a physical structure configured to be mounted within a particular type of lighting fixture housing. For example, the controller module has one or more rounded edges and installs or removes the controller module from an embedded lighting fixture that itself cannot be removed from a building structure such as a ceiling. It may be made easier.

  In one aspect, the controller module itself may have an internal modular structure. More specifically, the controller module provides compatibility of components used to receive input control signals and / or data at a “front end” input interface (eg, user interface, control network, sensor, etc.). You may comprise so that it may have. The controller module may be further configured to be compatible with components used to output control signals and / or data and / or power at a “back-end” output interface to the light generation module. In this regard, the controller module communicates with various light generation modules and / or networks, computers, or other controllers without the need for multiple hardware and / or software components simultaneously in the controller module. There is flexibility in ability. Such an arrangement can save space and / or cost when manufacturing the controller module for modular lighting fixtures and other applications.

According to another aspect, a light generation module for a modular lighting fixture is configured with some nominal data storage and processing capabilities to provide information to a controller associated with the lighting fixture, so that the fixture's separate It may be packaged as a controller module. For example, the light generation module provides information about one or more of the types of light sources present in the light generation module, their power requirements, operating temperature, operating time or temperature history, configuration parameters, and others Thus, a separate controller module may be able to supply appropriate drive signals and operating power to the light generation module.

  According to another aspect of the present disclosure, the controller module receives information, data and / or control signals from the light generation module in relation to any operational parameter or characteristic associated with the light generation module. Composed. The controller module may be programmed to change control signals and / or power output to the light generation module that it sends based on information received from the light generation module. For example, the light generation module indicates to the controller the voltage level or current level desired for the operation of that particular light generation module, and the controller supplies the appropriate voltage level and current level based on that information. May be.

It should be understood that it can be configured and / or controlled to generate radiation (eg, narrow bandwidth, wide bandwidth).

  For example, as an example of one embodiment of an LED configured to produce essentially white light (eg, a white LED), each of the different spectrum electroluminescents that are combined and mixed to form essentially white light. A number of dies that emit sense can be included. In another example embodiment, a white light LED can be associated with a phosphorous material that converts electroluminescence having a first spectrum to a different second spectrum. In one example of this embodiment, electroluminescence having a relatively short wavelength and a narrow bandwidth spectrum “pumps” the phosphor material so that the phosphor material emits long wavelength radiation having a somewhat broad spectrum. Radiate.

  It should also be understood that the term LED does not limit the physical and / or electrical package type of the LED. For example, as discussed above, an LED is a single light emitting device having multiple dies each configured to emit radiation of a different spectrum (eg, individually controllable or uncontrollable). May also refer to a device. An LED may also be associated with phosphorous, considered as an integral part of an LED (eg, some white LEDs).

However, the term “color” is generally used primarily to mean a characteristic of radiation that is perceivable by an observer (although this use is not intended to limit the scope of the term). Thus, the term “different colors” implies multiple spectra with different wavelength components and / or bandwidths. It should also be understood that the term “color” is used in connection with both white and non-white light.

DETAILED DESCRIPTION Various aspects of the present disclosure are described below, including some aspects specifically related to LED-based light sources. However, it is understood that the disclosure of the present invention is not limited to any particular implementation and that the various aspects explicitly discussed herein are primarily for illustration. Should.

  FIG. 1 shows an example of various components that can make up a lighting fixture 100 according to one aspect of the present disclosure. Some common examples of LED-based lighting fixtures, including components similar to those described below in relation to FIG. 1, include, for example, that patent is incorporated herein by reference. U.S. Pat. No. 6,016,038 entitled “Multicolored LED Lighting Method and Apparatus” issued to Mueller et al. On January 18, 2000, and Lys et al. Reference may be made to US Pat. No. 6,211,626, entitled “Illumination Components”.

  In various aspects of the present disclosure, the lighting fixture 100 shown in FIG. 1 may be used alone or other in a lighting fixture system (eg, discussed in more detail below in connection with FIG. 2). It may be used with similar lighting fixtures. Used alone or in combination with other lighting fixtures, the lighting fixture 100 includes, but is not limited to, internal or external space (eg architectural) lighting and lighting in general, direct or indirect lighting of objects or spaces, Theater or other entertainment-based / special effects lighting, decorative lighting, safety-oriented lighting, displays and / or lighting (such as in promotional and / or wholesale / consumer environments), lighting or communication with lighting In combination with a system or the like, it can be used for various indication purposes, display purposes, and information purposes.

  In one aspect, the lighting fixture 100 shown in FIG. 1 may include one or more light sources 104A, 104B, 104C, 104D (shown generally at 104), one or more of the light sources. May be an LED-based light source that includes one or more light emitting diodes (LEDs). In one aspect of this embodiment, any two or more of the light sources may be adapted to produce radiation of different colors (eg, red, green, blue), as discussed above in this regard Each of the different colored light sources produces a different source spectrum that constitutes a different “channel” of the “multi-channel” lighting fixture. Although FIG. 1 shows four light sources 104A, 104B, 104C, and 104D, the lighting fixture is not limited in this respect and essentially contains white light and produces a variety of different colored emissions. A different number of different types of light sources (all LED-based light sources, combinations of LED-based and non-LED-based light sources, etc.) adapted to do the lighting fixture 100 as discussed in more detail below. May be used.

  As shown in FIG. 1, the lighting fixture 100 also includes a controller configured to output one or more control signals that drive the light source to generate various intensities of light from the light source. 105 may be included. For example, in one example embodiment, the controller 105 outputs at least one control signal for each light source to independently control the light intensity generated by each light source (eg, radiated power in lumens). Or alternatively, the controller 105 may be configured to output one or more control signals that collectively control a group of two or more light sources in exactly the same manner. . Some examples of control signals that can be generated by the controller to control the light source include, but are not limited to, a pulse modulation signal, a pulse width modulation signal (PWM), a pulse amplitude modulation signal (PAM), a pulse Code modulation signals (PCM), analog control signals (eg, current control signals, voltage control signals), combinations and / or modulations of the aforementioned signals, or other control signals. In one aspect, particularly in connection with LED-based light sources, one or two to reduce potentially harmful or unpredictable variations in LED output that occur when variable LED drive current is used. One or more modulation techniques provide variable control using a constant current level that is passed through one or more LEDs. In another aspect, the controller 105 can control other dedicated circuits (not shown in FIG. 1), which can control the light sources to change their respective intensities.

  In general, the intensity of radiation generated by one or more light sources (radiant output power) is proportional to the average power delivered to the light source (s) over a given period. Thus, one technique for changing the intensity of radiation generated by one or more light sources involves modulating the power delivered to the light source (s) (ie, its operating power). This can be effectively achieved using pulse width modulation (PWM) techniques for certain types of light sources, including LED-based light sources.

In a method according to one exemplary aspect of the PWM control technique, for each channel of the lighting fixture, a constant predetermined voltage _Vsource is applied periodically across a given light _source that makes up the channel. The application of voltage _Vsource is accomplished by one or more switches not shown in FIG. While a voltage _Vsource is applied across the light source, a predetermined constant current _Isource can be passed through the light source (determined by a current regulator, also not shown in FIG. 1). Again, the LED-based light source has one or more LEDs so that a voltage _Vsource can be applied to the group of LEDs that make up the light _source and current I _source can be drawn by the group of LEDs. I want to remind you to include it. The instantaneous operating power P _{source of the} light _source is determined by the constant voltage V _{source at} both ends of the light source when energized and the adjustment current I _source drawn by the light source when energized (P _source = V _source · I _source ). As noted above, using regulated currents for LED-based light sources, potentially harmful or unpredictable variations in LED output that can occur when using variable LED drive currents Is reduced.

According to the PWM technique, an average delivered to a light source over a period of time by periodically applying a voltage V _source to the light _source and changing the time that the voltage is applied to the light source during a given on / off cycle. The power (average operating power) can be modulated. In particular, the controller 105 is pulsed (eg, one or two) at a frequency that is higher than the voltage V _source can be detected by a given light source, preferably by the human eye (eg, higher than about 100 Hz). A control signal for operating the above switches may be output and applied by applying voltage _Vsource to the light _source . In this way, the observer of the light generated by the light source does not perceive a discrete on-off cycle (commonly referred to as the “flicker effect”), but instead the eye integration function is essentially Perceive continuous light generation. By adjusting the pulse width (ie, on time or “duty cycle”) of the on / off cycle of the control signal, the controller changes the average amount of time that the light source is energized in any given period, and thus Change the average operating power of the light source. In this way, the perceived brightness of the light generated from each channel is changed.

  As will be discussed in more detail below, the controller 105 controls each different light source channel of the multi-channel lighting fixture with a predetermined average operating power, and for each light generated by each channel, a corresponding radiation output. It may be configured to provide power. Alternatively, the controller 105 specifies a predetermined operating power for one or more channels and thus a corresponding radiated output power for the light generated by each channel, a user interface 118, a signal source 124. Or commands (eg, “writing commands”) from various sources, such as one or more communication ports 120. Generating different perceived colors and brightness levels of light by the lighting fixture by changing the predetermined operating power for one or more channels (eg, following different commands or lighting commands) Can do.

  In one aspect of the lighting fixture 100, as described above, one or more of the light sources 104A, 104B, 104C, 104D shown in FIG. A group of different types of light sources (eg, parallel and / or series connection of various LEDs or other types of light sources) may be included. In addition, one or more of the light sources may have a variety of spectra including, but not limited to, various visible colors (including essentially white light), various color temperatures of white light, ultraviolet light, or infrared light. One or more LEDs adapted to produce radiation having any of (ie, wavelength or wavelength band) may be included. LEDs having different spectral bandwidths (eg, narrowband, wideband) can be used in various example embodiments of lighting fixture 100.

  In another aspect of the lighting fixture 100 shown in FIG. 1, the lighting fixture 100 can be constructed and arranged to produce a wide range of variable color radiation. For example, in one aspect, the lighting fixture 100 is a mixture of controllable variable intensity (ie variable radiated power) light generated by two or more light sources (essentially white with a wide range of color temperatures). It may be specifically arranged to produce mixed color light (including light). In particular, the color (or color temperature) of the mixed color light is one of the intensities (output radiated power) of each of the light sources (eg, in response to one or more control signals output by the controller 105) or It can be changed by changing two or more. In addition, the controller 105 provides control signals to one or more light sources to produce a wide range of static or time-varying (dynamic) multi-color (or multi-color temperature) lighting effects. You may comprise especially. To this end, in one aspect, the controller may include a processor 102 (eg, a microprocessor) programmed to provide such control signals to one or more of the light sources. In various aspects, the processor 102 may be programmed to autonomously provide such control signals in response to lighting commands or in response to various user or signal inputs.

  Accordingly, the lighting fixture 100 includes various colors of LEDs, including two or more of red, green, and blue LEDs, in various combinations, in addition to generating a color formulation, Two or more other LEDs may be included to generate a changing color and white light color temperature. For example, red, green and blue can be mixed with amber, white, UV, orange, IR or other LED colors. Such a combination of differently colored LEDs within the lighting fixture 100 can facilitate accurate reproduction of the desired spectrum of many lighting conditions, including, but not limited to, Various outdoor sunlight equivalents at different times of the day, various indoor lighting conditions, lighting conditions that simulate complex multicolored backgrounds, and others. Other desirable lighting conditions can be generated by excluding certain spectral portions that are specifically absorbed, attenuated or reflected in certain environments.

  As shown in FIG. 1, the lighting fixture 100 may include a memory 114 that stores various information. For example, the memory 114 generates one or more lighting commands or programs for execution by the processor 102 (eg, to generate one or more control signals for the light source), as well as variable color radiation. It may be used to store various types of data useful to do (eg, calibration information, discussed further below). The memory 114 may store one or more specific identifiers (e.g., serial numbers, addresses, etc.) that can be used at the local or system level to identify the lighting fixture 100. In various aspects, such an identifier may be pre-programmed by the manufacturer, e.g., received by the lighting fixture afterwards (e.g., via some user interface located on the lighting fixture). May be changeable (eg, via one or more data or control signals) or may not be changeable. Alternatively, such an identifier may be determined when the lighting fixture is first used in the field and subsequently made changeable again or not changeable.

  One problem that may arise in connection with controlling multiple light sources in the lighting fixture 100 of FIG. 1 and controlling multiple lighting fixtures in a lighting system is (eg, related to FIG. 2). (As discussed in detail below) with respect to potentially perceptible differences in light output between substantially similar light sources. For example, if there are two substantially identical light sources, each driven by the same control signal, the actual light intensity output by each light source (eg, radiated power in lumens) is measurable May be different. Such differences in light output can vary, including, for example, slight manufacturing differences between light sources, normal wear due to light source time, which can change each spectrum of generated radiation to a different value, etc. Can be attributed to various factors. For the purposes of this discussion, a light source for which the specific relationship between the control signal and the resulting output radiated power is unknown is referred to as an “uncalibrated” light source.

  Using one or more uncalibrated light sources in the lighting fixture 100 shown in FIG. 1 may result in light having an unpredictable or “uncalibrated” color or color temperature. For example, each having an adjustable parameter in the range of zero to 255 (0-255), with a maximum value 255 in response to a corresponding lighting command representing the maximum (ie, 100%) radiant power available from the light source. Consider a first lighting fixture that includes a first uncalibrated red light source and a first uncalibrated blue light source that are controlled. For the purposes of this example, if the red command is set to zero and the blue command is set to non-zero, blue light is generated, whereas the blue command is set to zero and the red command is set to non-zero. As a result, red light is generated. However, if both commands are changed from non-zero values, a variety of different colors can be produced in a perceptible range (eg, in this example, at least many different purple shades are possible). is there). Specifically, a specific desired color (eg, lavender) is probably obtained with a 125 value red command and a 200 value blue command.

  Next, a second lighting fixture including a second uncalibrated red light source substantially similar to the first uncalibrated red light source of the first lighting fixture, and the first lighting fixture first Consider a second uncalibrated blue light source substantially similar to the uncalibrated blue light source. As described above, the actual light intensity output by each red light source (eg, radiated power in lumens) even when both uncalibrated red light sources are controlled in response to their same commands. May vary within the measurable range. Similarly, even if both uncalibrated blue light sources are each controlled in response to the same command, the actual light output output by each blue light source may vary within a measurable range.

  In view of the foregoing, when a mixed color light as described above is generated using a combination of multiple uncalibrated light sources in a lighting fixture, it is generated by different lighting fixtures under the same control conditions It should be understood that the observed color (or color temperature) can vary within a perceptible range. Specifically, considering the example of the “lavender” again, the “first lavender” generated by the first lighting fixture with the red command of 125 and the blue command of 200 is: The red command with a value of 125 and the blue command with a value of 200 may differ from the “second lavender” generated by the second lighting fixture within a range that can be actually perceived. More generally, the first and second lighting fixtures produce uncalibrated colors because of their uncalibrated light sources.

  In view of the above, in one aspect of the disclosure according to the present invention, the lighting fixture 100 generates light having a color (eg, predictable and reproducible) calibrated at any given time. Includes calibration means that make it easy to do. In one aspect, the calibration means adjusts the light output of at least some light sources of the lighting fixture to compensate for perceptible differences between similar light sources used in different lighting fixtures (eg, scaling changes). ) Is configured to.

  For example, in one aspect, the processor 102 of the lighting fixture 100 outputs the radiation at a calibrated intensity that substantially corresponds in a predetermined manner with the control signal for the light source (s). It is configured to control one or more. As a result of mixed radiation having different spectra and respective configured intensities, calibrated colors are produced. In one aspect of this embodiment, at least one calibration value is stored in memory 114 for each light source, and the processor is calibrated by applying each calibration value to a control signal (command) for the corresponding light source. Is programmed to generate the desired intensity.

  In one aspect of this embodiment, one or more calibration values may be determined once (eg, during the lighting fixture manufacturing / testing phase) and stored in memory 114 for use by processor 102. Good. In another aspect, the processor 102 is configured to dynamically (sometimes) derive one or more calibration values using, for example, one or more optical sensors. Also good. In various aspects, the light sensor (s) can be one or more external components coupled to the lighting fixture, or alternatively integrated as part of the lighting fixture itself. Also good. The light sensor is an example of a signal source that can be integrated with the lighting fixture 100 or otherwise associated therewith and monitored by the processor 102 in relation to the operation of the lighting fixture. Other examples of such signal sources are discussed in detail below in connection with the signal source 124 shown in FIG.

  One exemplary method that can be implemented by the processor 102 to derive one or more calibration values is to apply a reference control signal (eg, corresponding to maximum output radiated power) to the light source, Measuring the intensity of the radiation generated by the light source (e.g., the radiated power impinging on the photosensor) (e.g., by one or more photosensors). The processor may then be programmed to compare the measured intensity with at least one reference value (eg, representative of the nominally expected intensity in response to the reference control signal). Based on such a comparison, the processor can determine one or more calibration values (eg, scaling factors). In particular, the processor, when applied to a reference control signal, causes the light source to output radiation having an intensity corresponding to a reference value (ie, “expected” intensity, eg, expected radiated power in lumens). A calibration value can be derived.

  In various aspects, for a given light source, one calibration value may be derived for the entire range of control signal / output intensity. Alternatively, multiple calibration values each applied over different control signal / power intensity ranges may be derived for a given light source to approximate the nonlinear calibration function by piecewise linear methods (ie, there is A number of calibration values "samples" may be obtained).

  In another aspect, as also shown in FIG. 1, the lighting fixture 100 optionally includes a number of user-selectable settings or functions (eg, the overall light output of the lighting fixture 100). Controlling, changing and / or selecting various pre-programmed lighting effects generated by the lighting fixture, changing and / or selecting various parameters of the selected lighting effect, for the lighting fixture , One or more user interfaces 118 may be included that are provided to facilitate any of the following: setting a unique identifier such as an address or serial number, etc.). In various aspects, communication between the user interface 118 and the lighting fixture may be accomplished by wire or cable, or wireless transmission.

  In one aspect, the lighting fixture controller 105 monitors the user interface 118 based at least in part on the user's operation of the interface, and one or more of the light sources 104A, 104B, 104C, 104D. To control. For example, the controller 105 may be configured to respond to user interface operations by initiating one or more control signals to control one or more of the light sources. Alternatively, the processor 102 selects one or more pre-programmed control signals stored in the memory, modifies the control signals generated by executing the writing program, from the memory It may be configured to respond by selecting and executing a new lighting program or otherwise affecting the radiation generated by one or more of the light sources.

  In particular, in one example aspect, the user interface 118 may constitute one or more switches (eg, standard wall switches) that interrupt power to the controller 105. In one aspect of this example embodiment, the controller 105 monitors power as controlled by the user interface, and then based at least in part on the duration of the power interruption caused by operation of the user interface, It is configured to control one or more. As described above, the controller may, for example, select one or more pre-programmed control signals stored in memory, modify the control signals generated by executing the lighting program, Select and execute a new lighting program from memory or otherwise affect the radiation generated by one or more of the light sources to respond to a predetermined duration of power interruption It may be particularly configured.

  FIG. 1 also illustrates that the lighting fixture 100 may be configured to receive one or more signals from one or more other signal sources 124. In an example aspect, the lighting fixture controller 105 may control one or more of the light sources 104A, 104B, 104C, 104D in a manner similar to that disclosed in connection with the user interface. Use signal (s) 122, alone or in combination with other control signals (eg, signals generated by executing a lighting program, one or more outputs from a user interface, etc.) May be.

  Examples of signal (s) 122 that can be received and processed by controller 105 include, but are not limited to, one or more audio signals, video signals, power signals, and various types of data signals. , A signal representing information obtained from a network (eg, the Internet), a signal representing one or more detectable / sensing conditions, a signal from a lighting fixture, a signal consisting of modulated light, and the like. In various example embodiments, the signal source (s) 124 may be located remotely from the lighting fixture 100 or included as a component of the lighting fixture. In one aspect, a signal from one lighting fixture 100 may be sent over the network to another lighting fixture 100.

  Some examples of signal sources 124 that can be used in or associated with the lighting device 100 of FIG. 1 generate one or more signals 122 in response to some stimulus. And any of a variety of sensors or transducers. Examples of such sensors include, but are not limited to, heat sensitive (eg, temperature, infrared) sensors, humidity sensors, motion sensors, photo sensors / light sensors (eg, photodiodes, spectroradiometers). Or sensors sensitive to one or more specific electromagnetic radiation spectra, such as spectrophotometers, etc., various types of cameras, acoustic or vibration sensors or other pressure / force transducers (e.g. , Microphones, piezoelectric elements), and other types of environmental condition sensors.

  Further examples of signal source 124 include electrical signals or characteristics (eg, voltage, current, power, resistance, capacitance, inductance, etc.) or chemical / biological characteristics (eg, acidity, one or more). Various metering / detection devices that monitor certain chemical or biological substances, bacteria, etc.) and provide one or more signals 122 based on their signal or characteristic measurements Can be mentioned. Still other examples of the signal source 124 include various types of scanners, image recognition systems, audio or other acoustic recognition systems, artificial intelligence and robotic systems, and the like. Signal source 124 may be lighting fixture 100, another controller or processor, or media player, MP3 player, computer, DVD player, CD player, television signal source, camera signal source, microphone, speaker, telephone, cellular phone, instant. It can also be any of a number of available signal generators such as messenger devices, SMS devices, wireless devices, personal organizer devices, and others.

  In one aspect, the lighting fixture 100 shown in FIG. 1 may also include one or more optical elements 130 that optically process the radiation generated by the light sources 104A, 104B, 104C, 104D. . For example, one or more optical elements can be configured to change one or both of the spatial distribution and direction of propagation of the generated radiation. In particular, one or more optical elements may be configured to change the diffusion angle of the generated radiation. In one aspect of this embodiment, one or more of the optical elements 130 may include one or more of the spatial distribution and direction of propagation of generated radiation (eg, in response to some electrical and / or mechanical stimulus). It can be specifically configured to variably change both. Examples of optical elements that can be included in the lighting fixture 100 include, but are not limited to, reflective materials, refractive materials, transparent materials, filters, lenses, mirrors, and optical fibers. The optical element 130 can also include phosphors, phosphors, or other materials that can respond to or interact with the generated radiation.

  As also shown in FIG. 1, the lighting fixture 100 includes one or more communication ports 120 to facilitate coupling the lighting device 100 to any of a variety of other devices. be able to. For example, one or more communication ports 120 facilitates coupling multiple lighting fixtures together as a networked lighting system, in which at least some lighting systems are addressable. Be responsive to specific data transported across the network (eg, having a specific identifier or address).

  In particular, in a networked lighting system environment, each lighting fixture that is coupled to the network when data is transmitted over the network, as discussed in more detail below (eg, in connection with FIG. 2). The fixture controller 105 can be configured to respond to specific data (eg, lighting control commands) related thereto (eg, as specified by the respective identifiers of the networked lighting fixtures). . When a given controller identifies specific data addressed to it, the controller reads the data and determines the lighting conditions generated by its light source, eg, according to the received data (eg, appropriate to the light source). Change) by generating a control signal. In one aspect, the memory 114 of each lighting fixture coupled to the network may be loaded with a table of lighting control signals corresponding to, for example, data received by the controller processor 102. When the processor 102 receives data from the network, the processor examines the table and selects a control signal corresponding to the received data and controls the lighting fixture light source accordingly.

  In one aspect of this embodiment, the processor 102 for a given lighting fixture may or may not be coupled to a network for some programmable lighting applications in the lighting industry (eg, US patents). Configured to interpret lighting commands / data received in the MDX protocol, which is the lighting command protocol used (as discussed in 6,016,038 and 6,211,626). May be. For example, in one aspect, considering lighting fixtures based on red, green, and blue LEDs (ie, “RGB” lighting fixtures) for the time being, the lighting commands according to the DMX protocol are red channel commands, green channel commands, and blue Each channel command may be defined as 8-bit data (i.e., data bytes) representing values from 0 to 255. The maximum value 255 for any of the color channels causes the processor 102 to control the corresponding light source (s) to operate at the maximum (100%) available power on that channel, thereby allowing for that color. Command to generate maximum available radiated power (command structures for such RGB lighting fixtures are commonly referred to as 24-bit color control). Thus, an instruction of the format [R, G, B] = [255,255,255] causes the lighting fixture to generate maximum radiated power for each of red, green and blue light (thereby Producing white light).

  However, the lighting fixtures according to various aspects can be configured to be responsive to other types of communication protocols / lighting command formats to control the respective light sources, so It should be understood that a lighting fixture suitable for the purpose is not limited to the DMX command format. In general, the processor 102 is responsive to lighting commands in various formats that represent a specified operating power for each different channel of the multi-channel lighting fixture by some measure that represents from zero to maximum available operating power for each channel. Can be configured.

  In one aspect, the lighting fixture 100 of FIG. 1 can include and / or be coupled to one or more power supplies 108.

Can be realized. Examples of such configurations include, but are not limited to, essentially linear or curvilinear configurations, circular configurations or elliptical configurations, rectangular configurations, combinations of the foregoing, and various other geometric shapes. Configurations, various two-dimensional or three-dimensional configurations, and the like. A given lighting fixture may also include a mounting mechanism for a variety of light source (s), a housing / housing mechanism and shape that partially or wholly encloses the light source, and / or an electrical or mechanical connection.

Can be packaged in various ways, for example, in one aspect, any subset of various lighting fixture components or The whole, as well as other components that can be associated with the lighting fixture, can be packaged together. In another aspect, some of the packaged components can be coupled together electrically and / or mechanically in a variety of ways, as discussed below.

  FIG. 2 shows an example of a networked lighting system 200 according to one aspect of the disclosure according to the present invention. In the embodiment of FIG. 2, a number of lighting fixtures or fixtures 100, similar to those described above in connection with FIG. 1, are coupled together to form a networked lighting system. However, it should be understood that the specific configuration and mechanism of the lighting fixture shown in FIG. 2 is for illustration only and that the disclosure of the present invention is not limited to the specific system topology shown in FIG. It is.

  Further, although not explicitly shown in FIG. 2, networked lighting system 200 includes one or more signal sources, such as sensors / transducers, in addition to one or more user interfaces. Thus, it should be understood that it may be configured flexibly. For example, one or more user interfaces and / or one or more signal sources, such as sensors / transducers (as described above in connection with FIG. 1) It can be associated with any one or more of the tools. Alternatively (or in addition to the foregoing), one or more user interfaces and / or one or more signal sources may be used as “stand alone” components within networked lighting system 200. It may be realized. Whether stand-alone components or specifically associated with one or more lighting fixtures 100, these devices can be “shared” by the lighting fixtures of the networked lighting system. In other words, one or more signal sources, such as one or more user interfaces and / or sensors / transducers, within a networked lighting system, any one or two of the system's lighting fixtures. A “shared resource” can be constructed that can be used in connection with controlling one or more.

  As shown in the embodiment of FIG. 2, the lighting system 200 may include one or more lighting fixture controllers (hereinafter “LUC”) 208A, 208B, 208C, 208D, each LUC coupled to it. It communicates with one or more of the lighting fixtures 100 and is responsible for overall control thereof. Although FIG. 2 shows one lighting fixture 100 coupled to each LUC, the disclosure according to the present invention is not limited in this regard, and different numbers of lighting fixtures 100 can be connected to a variety of different communications. It should be understood that media and protocols can be used to couple to a given LUC in a variety of different configurations (serial connection, parallel connection, combination of serial and parallel connections, etc.).

  In the system of FIG. 2, each LUC may be coupled to a central controller 202 that is configured to communicate with one or more LUCs. Although FIG. 2 shows four LUCs coupled to the central controller 202 via a general connection 204 (which may include any number of various conventional coupling devices, switching devices and / or networking devices). It should be understood that according to various aspects, a different number of LUCs may be coupled to the central controller 202. Further in accordance with various aspects of the present disclosure, the LUC and central controller can be combined together in a variety of configurations to form a networked lighting system 200 using a variety of different communication media and protocols. can do. Furthermore, it should be understood that the interconnection of the LUC and the central controller, and the interconnection of the lighting fixture to each LUC can be accomplished in different ways (eg, using different configurations, communication media, and protocols). is there.

  For example, according to one aspect of the present disclosure, the central controller 202 shown in FIG. 2 is configured to implement LUC and Ethernet-based communication, and the LUC is connected to the lighting fixture 100. You may comprise so that DMX base communication may be implement | achieved. In particular, in one aspect of this embodiment, each LUC is configured as an addressable Ethernet-based controller and accordingly uses a specific unique address (or unique address) using an Ethernet-based protocol. The central controller 202 may be identifiable via an address group. In this way, the central controller 202 is configured to support Ethernet communications throughout the network of coupled LUCs, and each LUC can respond to communications addressed to it. In contrast, each LUC, based on Ethernet communication with the central controller 202, sends lighting control information to one or more lighting fixtures coupled thereto, for example via the DMX protocol. Can communicate.

  More specifically, according to one aspect, the LUCs 208A, 208B, 208C shown in FIG. 2 provide high-level commands that need to be interpreted by the LUC before the lighting control information can be transferred to the lighting fixture 100. It can be “intelligent” in that the central controller 202 can be configured to communicate to the LUC. For example, if a lighting system operator places lighting fixtures in a specific arrangement with each other, the lighting fixtures to lighting fixtures generate a rainbow color appearance that propagates ("rainbow chase"). You may want to create a color changing effect that changes color. In this example, the operator accomplishes this by providing a simple command to the central controller 202, which uses an Ethernet-based protocol high-level command to generate a “rainbow chase”. To one or more LUCs. The command may include, for example, timing, intensity, hue, saturation, or other relevant information. When a given LUC receives such a command, it then interprets the command and communicates further commands to one or more lighting fixtures using the DMX protocol, in response to the lighting Each source of fixture is controlled via any of a variety of signaling techniques (eg, PWM).

  Again, in the lighting system according to one aspect of the disclosure of the present application, the above example of using a plurality of different communication modes (eg, Ethernet / MDX) is for illustrative purposes only. It should be understood that the disclosure of the present invention is not limited to this particular example.

  From the foregoing, one or more lighting fixtures described above produce white light with variable color temperature over a wide color temperature range in addition to highly controllable variable color light over a wide color range. You will understand that you can.

  FIG. 3 shows a partially cutaway perspective view of a lighting fixture 100 having a modular structure, according to one aspect of the disclosure according to the present invention. A light generation module 300, such as an LED base module, is detachable from a mating socket 302. The socket 392 is fixedly coupled to the housing 304 (eg, via a screw inserted through a hole 306 in the flange 308 of the socket 302) to facilitate the light generation module 300 into the housing 304 via the socket 302. The lighting fixture 100 can be formed. In some exemplary aspects, the housing 304 serves as a heat sink (eg, the housing is formed of a highly thermally conductive material, such as die cast or extruded metal). The lighting fixture 100 of this aspect further includes a controller module 105 as a component separated from the light generation module 300 that can be permanently or replaceably mounted within the housing 304.

In some aspects of the lighting fixture, the lighting fixture 100 includes a heat dissipating element 320 (in this embodiment, a fin) for transferring heat out of the light generation module 300 and / or the controller module 105. For example, the socket 302 may be formed of a thermally conductive material that transfers heat to fins or other suitable heat dissipating elements to facilitate the transfer of heat from the light generating module 300 to the housing 304. A wiring knockout 322 and a wiring compartment door 324 are also visible in the figure. In some aspects, a separate heat dissipating element (ie, thermally insulated from the heat dissipating element that transfers heat out of the light generating module) is provided to transfer heat out of the controller module 105. In other embodiments, however, the same heat dissipating element transfers heat out of both the light generation module 300 and the controller module 105.

The combination of base plate 340, hexagonal subassembly 344 and printed circuit board 346 is covered with an electrically insulative thermally conductive layer 348 (eg, through a hole in the base plate and threaded bore in chassis 336). May be coupled to the chassis 336 (via screws that engage). The light passing faceplate 330 may also optionally be used in the light generation module 300 and may be held in place by the grip ring 332. The base plate 340 may include a cut-out or through-hole 350 that houses a connector 352 that connects to the LED assembly 338. Referring again to FIG. 3, in one aspect, the connector 352 essentially serves as a first electrical connector portion that engages the connector 310 in the fixture housing 304, which is a light generation module. Serves as an auxiliary second electrical connection when the is mounted in the socket 302.

  For thermal management, dissipating heat through the front (light emitting surface) of the light generating module can aid in thermal efficiency. In assembling the light generating module 300 of FIG. 9, an electrically insulating thermally conductive layer 348 may be used between the LED assembly 338 and the chassis 336, as shown in FIG. In this way, heat transfer is through the front of the LED assembly (via the printed circuit board 346, the thermally conductive layer 348, and the die cast metal chassis 336) and through the back of the LED assembly 338 (optional A selected thermal paste or grease can be generated via the base plate 340, ultimately in the direction of the other heat sink to which the housing or base plate is coupled (see, eg, FIG. 3). Components other than the chassis may be made of a thermally conductive material, and various die cast components may be painted / anodized black to facilitate heat transfer.

  The particular embodiment shown in FIGS. 7-9 illustrates a module that houses six LED hexagon subassemblies 344, but the disclosure according to the present invention is not limited in this respect, and in other embodiments It should be understood that different configurations and numbers of LED subassemblies 344 can be used. Further, in any of the aspects described herein, an LED hexagon subassembly can be replaced with an LED subassembly having a shape other than a hexagon.

  10 is an enlarged front view of the LED assembly 338 of the light generation module 300 shown in FIG. In particular, FIG. 10 shows six LED hexagon subassemblies 344 (eg, an OSTAR® subassembly, discussed in further detail below) coupled to a printed circuit board 346. As can be seen in FIG. 10, each hexagonal subassembly 344 has six individual LED junctions electrically interconnected within the subassembly to operate simultaneously in response to a drive signal supplied to the subassembly. 358. Each subassembly also includes a primary optic 360, which can be a lens configured to provide a Lambert beam shape. As discussed below, the hexagon subassembly 344 is coupled to the back or bottom surface of the printed circuit board 346, which has a through hole for the primary optical component 360 of each LED hexagon subassembly 344. It is configured as follows. Large through-holes 364 in printed circuit board 346 facilitate attachment of base plate 340 and LED assembly 338 to chassis 336.

  In one example embodiment, LED hexagon subassembly 344 is manufactured under the OSTAL® name by OSRAM Opto Semiconductors GmbH (see http://www.osram-os.com/ostar-lighting). It may be a component. Each OSTAL® subassembly 344 is capable of up to 400 lumens at 700 milliamps operating current from six LED junctions that are driven simultaneously to provide white light having a color temperature of about 5600 ° K. Can bring about radiation.

  In one aspect, the LED hexagon subassembly 344, exemplified by the OSTAL® product, can be implemented as a “chip on board” LED subassembly or module. In a chip-on-board assembly, an unpackaged silicon die (ie, a semiconductor chip) is attached directly to the surface of a substrate (eg, FR-4 printed circuit board, flexible printed circuit board, ceramic substrate, etc.) Are then wire bonded to form an electrical connection to the substrate. An epoxy resin or silicone coating is then applied to the top surface of the die / chip to encapsulate and protect the die / chip. In one exemplary OSTAR® configuration, the LED hexagon subassembly 344 includes four or six LED semiconductor chips mounted on a ceramic substrate that is directly on the surface of the metal core printed circuit board. Mounted. In order to protect the semiconductor chip from environmental influences such as moisture, the chip may be coated with a clear silicone capsule.

  Each OSTAR® includes an aluminum core substrate to promote heat dissipation, on which an electrical connection, an LED junction (semiconductor chip), and a Lambertian beam shape are provided ( As an example of a primary optical component, an integrated primary lens is arranged. The hexagonal substrate allows coupling of the subassembly to the chassis 336 via screws and facilitates alignment of the individual hexagonal subassembly to the common substrate and optional secondary optics. A plurality of outer peripheral cutouts and / or through holes are provided. Electrical connection to the hex subassembly can be made by soldering to the top contact of the subassembly or by using a spring-type contact. OSTARS® aluminum substrates, in some aspects, are thermally conductive, such as base plate 340, socket 302, and / or fixture housing 304, to provide a thermal conduction path out of the LED subassembly. Located in direct contact with the structure.

  Although LED hexagonal subassemblies constructed with OSTAR (R) components have been discussed above, the disclosure according to the present invention is not limited in this respect and is essentially white light having various color temperatures, And / or other configurations of LED hexagonal sub-assemblies including one or more LEDs configured to generate light having a variety of non-white light are also used in light generation modules according to various aspects. It should be understood that it can be done.

  In particular, in one exemplary embodiment, one or more LED subassemblies of a given LED assembly can generate white light having a first color temperature, and one or more of the LED subassemblies Two or more others can generate white light having a different second color temperature such that a given light generation module is configured as a multi-channel LED-based light source. Similarly, a lighting fixture that includes such a multi-channel light generation module can be formed by a multi-channel controller module that is configured to independently control multiple channels of the multi-channel light generation module. In this way, the light generation module can be configured to generate either a different color temperature or any combination of different color temperatures. Accordingly, the lighting fixture according to the disclosure of the present invention may be configured to supply controllable variable color temperature white light, particularly from a single light generation module.

  FIG. 11 is an enlarged rear view of the LED assembly 338, providing the rear mounting of the LED hex subassembly 344 to the printed circuit board 346 and one or more drive signals for operating the hex subassembly. Electrical connector 352 is shown. From FIG. 11, the rear surface 368 of the aluminum substrate of each hexagonal subassembly 344 can be clearly seen. Referring again to FIG. 9, in one aspect of this embodiment, the rear surface of the hex subassembly is coupled to an aluminum base plate 340 to facilitate heat transfer from the back surface (or bottom surface) of the hex subassembly. In one embodiment example, thermal grease or paste is used to affix the base plate 340 to the LED assembly 338 and align the through holes 370 in the base plate 340 with the large through holes 364 in the printed circuit board 346. The base plate and the LED assembly may be easily attached to the chassis 336. As described above, the base plate 340 may include a central notch or through hole to allow clearance of the electrical connector 352.

  From FIGS. 9-11, it may be observed that the printed circuit board 346 includes a number of small alignment through holes 372 aligned with semicircular notches 374 on the outer periphery of the hexagonal subassembly 344. unknown. These through holes 372 facilitate coupling the subassembly to the printed circuit board 346, as discussed below in connection with FIGS.

  FIG. 12 shows a “jig” 380 that can be used to facilitate assembly of the LED assembly 338. The jig 380 can be constructed of any rigid material such as an aluminum plate. As shown in FIG. 12, the aluminum plate may include a number of holes in which small pegs 384 and large pegs 386 are installed. As will be apparent from subsequent discussion and figures, the different sized pegs ensure proper alignment between the hex subassembly 344 and the printed circuit board 346.

  More specifically, FIG. 13 shows a multiple LED hexagon subassembly 344 positioned on the small peg 384 of the jig 380 shown in FIG. 12 to hold the subassembly flat in place. Yes. Once positioned, solder paste may be applied to the upper electrical contact pads 388 of the subassembly. As shown in FIG. 14, the printed circuit board 346 is then positioned on the jig 380 from above the subassembly 344 using a large peg 386 that passes through a large through hole 346 in the printed circuit board 346. Is done. The printed circuit board also includes a small through hole 372 for receiving a small peg 384.

  On one side of the printed circuit board 346 adjacent to the hex subassembly (ie, the side opposite that seen in FIG. 14), the first electrical contact ( For example, copper pads not shown), which provide both mechanical attachment points and electrical connections to the hex subassembly. In one example embodiment, these first electrical contacts have mating second electrical contacts 390 on the opposite side of the printed circuit board 346 (the side visible in FIG. 14); A pair of contacts on opposite sides of the printed circuit board can be connected through a plated through hole 392 in the center of the contacts. Thus, once positioned on the jig, solder paste is sandwiched between the contact pads 388 of the hexagonal subassembly 344 and the first electrical contacts of the printed circuit board (eg, hot rod or solder). Heat may be applied to the second electrical contact 390 (via the iron tip), thereby melting the solder paste to form electrical and mechanical bonds between the hex subassembly and the printed circuit board. The plated through hole 392 facilitates heat transfer through the contacts and allows visual inspection of the solder joint.

  In one example embodiment, the printed circuit board 346 may be made of a conventional FR-4 (Flame Resistant 4) material, which is commonly used to manufacture printed circuit boards. An epoxy resin composite reinforced with a glass fiber woven mat. In one aspect, the printed circuit board 346 made of FR-4 may be fabricated as a relatively thin substrate to facilitate effective heat transfer from the front (or top) of the hex subassembly. Thus, when the LED assembly 338 is coupled to the die cast chassis 336, the chassis metal further facilitates heat transfer from the front (or light emitting surface) of the light generating module.

  In another example embodiment, the printed circuit board may be made of a flexible circuit board material. Flexible circuit boards are used in certain common conventional applications where rigid circuit boards or handwiring is limited due to flexibility, space savings, and manufacturing constraints. In addition to cameras, a common application for flexible circuits is computer keyboard manufacturing, and most keyboards currently manufactured use flexible circuits for switch matrices. In one example, the flexible circuit board can be realized as a fairly thin board (e.g., on the order of a few microns) using thin flexible plastic or other insulating material and metal foil.

  An example of a flexible insulating material suitable for flexible circuit boards is Kapton®, which is a polyimide film developed by DuPont®, which is −269 ° C. to + 400 ° C. (−452 ° F. − Stability can be maintained over a wide temperature range of 752 ° F.). In one example of an LED assembly that uses a flexible circuit board, a window may be cut into the insulating material on both the top and bottom surfaces of the circuit board to expose the contact pad areas in the conductive metal foil layer. A hole may be formed in the center of these regions to facilitate the soldering process as described above. In one aspect of an example embodiment using a flexible circuit board, a non-planar LED assembly is manufactured to allow customized or predetermined patterns and orientations of light emission from the LEDs of the hex subassembly. Thus, it can be appropriately mounted on the chassis.

  In an example of one embodiment using a flexible circuit board, an aluminum base plate that serves as an alternative to the base plate 340 is shown in FIG. 12 so that the LED hexagon subassembly is initially mounted in place on the rigid base plate. Pegs similar to those shown may be equipped. The pegs in the base plate then also serve to facilitate alignment of the flexible circuit board, and these pegs are placed on top of the hex subassembly and joined to the subassembly in a similar manner as described above. May be.

  FIG. 15 is an enlarged view of the secondary optical component 334 of the light generation module 300 shown in FIG. Each secondary optical component is configured with four posts 402 that engage with four corresponding through-holes 372 in the printed circuit board and associated LED. Facilitates alignment of the secondary optics over the primary optics of the hexagonal subassembly 344. Each secondary optic 334 also includes one or more clips 404 to facilitate engagement of the secondary optic with one of the secondary optic receiving portions of the chassis 336. More specifically, referring to FIGS. 9, 25, 26, each secondary optic fits snugly into a corresponding secondary optic receiving portion or chamber 502 of chassis 336, one or more. The clip 404 engages a portion of the bottom surface 504 of the chassis 336. The secondary optic post 402 passes through the secondary optic receiving portion or chamber of the chassis and includes a small through hole 372 and a peripheral semi-circular notch in the associated LED hex subassembly (see, eg, FIGS. 10 and 11). Engaging with 374 ensures that the secondary optic is properly aligned with the primary optic of its associated LED hexagon subassembly. In various aspects, the secondary optic is configured with a buffled surface, a curved surface, and / or a reflective surface to provide a variety of beam profiles for light emitted by the LED hexagon subassembly ( For example, it is easy to generate a narrow beam and an intermediate beam.

  A slightly different embodiment of the secondary optic component 334-1 is shown in FIGS. In this embodiment, the four posts 402-1 include a flat outward surface 406 rather than a curved outward surface as shown in the embodiment of FIG.

  18 and 19 are perspective views showing a decorative design of one embodiment of the round pack light generation module 300-1, including a chassis 336-1, a base plate 340-1, and a connector 352-1. FIG. 20 is a side view of the light generation module 3000-1 shown in FIGS. FIG. 21 is a top view showing a decorative design of another aspect of the round light generating module 300-2 coupled to the socket 302-2 via the grip ring 332-2, where the socket flange 308 is shown. -2 is visible. 22 is a cross-sectional view of the light generation module and grip ring, taken along line 22-22 in FIG. FIG. 23 is a perspective view of the light generation module 300-2, the grip ring 332-2, and the socket 302-2 of FIG. 24 is a perspective rear view of the light generation module 300-2 and the grip ring 332-2 in FIG.

  In one exemplary embodiment of the module, grip ring and socket combination shown in FIGS. 22-24, the socket and grip ring essentially form two coupling collars, the at least one external structure of the socket and the grip ring At least one internal structure with complementary threads, easy to be mechanically connected in a screw-type interlocking manner when the grip ring is installed on the socket and rotated against it Turn into. Thus, when the light generating module is installed in the socket, the grip ring fits over at least a portion of the outer periphery of the light generating module and enters the socket via a threaded (rotating) interlocking mechanical connection. It is configured to hold a light generation module.

  FIG. 25 is a top view of a decorative design of one aspect of chassis 336-1 that includes multiple chambers 502. FIG. FIG. 26 is a perspective bottom view of the chassis 336-1 of FIG. 25, with a number of screws formed in the body of the chassis for receiving screws that can be used to couple the base plate and LED assembly to the chassis. Shows a bore with a mountain.

  27 and 28 show two different exploded perspective views of a light generation module 300-3 and a grip ring 332-3 according to an alternative aspect of the present disclosure. FIG. 42 (described in detail below) shows a light generation module 300-3 based on the various components shown in the perspective views of FIGS. 27 and 28, and the assembled light generation module 300-3 includes: Coupled to the coupling socket 302-1 to form the lighting fixture 100.

  In the embodiment of FIGS. 27 and 28, unlike the embodiment described above with respect to FIGS. 7-9, an LED assembly 338-1 including a number of LED hexagon subassemblies 344-1 includes a thermally conductive baseplate and printed circuit. It is not disposed so as to be sandwiched between the plate substrate and is configured to be inserted into the chassis 336-2 instead.

  FIGS. 29 and 30 show various perspective views of the chassis 336-2 including six complementary receiving portions or chambers that house six LED hexagon subassemblies 344-1. In one aspect of this embodiment, the chassis 336-2 may be a plastic injection molded part. In addition, the chassis 336-2 is configured to include a number of electrical connectors 410 and contacts 412 integral with the body of the chassis 336-2 so that each of the LED hexagon subassemblies 344-1 has a chassis 336-2. The operating power may be supplied from the main connector assembly 352-2 disposed in the central channel. One special layout of electrical contacts 412 and connectors 410 is shown in the top view of FIG.

  In various aspects, the electrical contacts or connectors of chassis 336-2 include components that are insert molded into the chassis, stamped pieces that can be pushed into the chassis during assembly, flex printed circuit boards ( flex PCB), or conductive ink that covers the molded chassis. The LED hexagon subassembly 344-1 may be assembled into the chassis 336-2 by pressing to ensure sufficient electrical contact with the chassis contacts or connectors. To facilitate sufficient contact, the chassis may further include small fasteners or retaining clips within the injection molded plastic.

  Referring again to FIGS. 27 and 28, once the LED assembly 300-3, including the LED hex subassembly 344-1, is assembled into the chassis 336-2, the stamped aluminum base plate 340-2 is countersunk. (Counter-sunk) can be attached to chassis 336-2 via screws that penetrate through-holes 414 (see FIG. 28) (and the base plate material can be copper, graphite or other suitable thermally conductive material) Can be). The base plate 340-2 also includes a central through hole 350-1 for the connector assembly 352-2, but in some aspects, the through hole 350-1 is not in the center of the base plate 340-2 and some In the embodiment, there is no through hole 350-1. Base plate 340-2 may provide a thermal connection to the housing, as described above with reference to FIG. The gap pad 414 may include a thermal material, optionally positioned adjacent to the bottom surface of the aluminum base plate 340-2 and attached via thermal paste or thermal grease. In general, gap pads can be used to tightly bond two surfaces and remove voids that are present when two bare surfaces are bonded.

  In various example embodiments, other alternative thermal materials can be used, such as a viscous paste or a liquid metal sandwiched between a plate and a slightly recessed thin sheet. When the light generating module is locked into engagement with the socket, the recessed sheet deforms under compression and against a fixture housing (eg, a heat sink, described below with reference to FIG. 43). And become flat. Alternatively, a thin sheet of a very soft material such as indium (Brinell hardness 0.9) that can be deformed under pressure can be replaced by a gap pad. In another aspect, the gap pad or other thermal material is manufactured with wings or flaps that fold through or around the base plate and are clamped / captured when the base plate is fastened to the chassis. May be.

  As described above, the various components and / or subassemblies of the light generation module 300 can be configured to conduct heat out of the light generation module 300. In some aspects, the chassis 336 is die cast with metal or formed of other suitable thermally conductive material so that heat is transferred from the LED assembly 338 to the faceplate 330 and / or the grip ring 332. It may be. The electrically insulative thermally conductive layer 348 described above may be inserted between the LED assembly 338 and the chassis 336 as part of promoting heat dissipation. In this way, heat dissipation can be promoted from the front and / or both sides of the light generation module 300.

  Heat dissipation can also be promoted from the rear side of the light generation module 300 in some aspects. For example, a thermally conductive base plate 370 can be provided as a backing for the LED assembly 338 to facilitate heat dissipation through a housing and / or socket to which the light generating module 300 is attached.

  As shown in FIGS. 32-39, the light generation module may include one or more active heat dissipation components, such as fans, and / or passive heat, such as fins or air circuits or channels. A diffusion mechanism may be included. Such aspects are useful for certain LED assemblies and light generation modules in that the use of heat dissipation components can make the light generation module stand alone in heat dissipation. That is, thermal coupling to the housing or other fixture is not required for proper heat dissipation. In this way, flexibility is gained in associating the light generation module with various lighting fixtures and systems.

  One embodiment of a light generation module 300-4 that uses heat dissipating fins 510 is shown in FIGS. In this embodiment, the fin 510 is integral with the light generation module 300-4 in that the fin 510 is included as part of the die cast metal light generation module housing 512. The LED assembly 514 is thermally coupled to the die cast housing 512 such that heat is transferred to the heat dissipating fins 510. The module housing 512 includes an insert molded copper core 516 and an injection molded flange 518 for engaging engagement with a socket 302-2 as shown in FIG. The socket 302-2 in this embodiment is die cast metal, but in this embodiment, the plastic flange 518 prevents appreciable amount of heat from being transferred to the socket 302-2. In some aspects, the socket 302-2 may be thermally conductive to facilitate heat transfer.

  The module housing 512 includes a leaf spring 520 for forming operating power and a control connection with the socket 302-2 when the light generation module 300-4 engages the socket 302-2.

  One aspect of the light generation module 300-5 including the fan 530 is shown in FIG. The fan 530 is disposed between the LED assembly 338-2 and the module housing 512-1. The fan 530 may be a low speed (RPM) fan that draws air into the housing 512-1 through the intake 532 and exhausts air from the module 300-5 through the outlet 534. . During operation, heat is transferred from the LED subassembly 344-2 through the metal core printed circuit board 346-1 to the heat dissipation fins 510-1. The air flow generated by the fan 530 passes over the heat dissipating fins 510-1 and removes heat from the heat dissipating fins 510-1 before exiting the module housing 512-1 via the outlet 534. . Any air flow passing over the metal core printed circuit board 346-1 and / or the LED subassembly 344-2 will also remove heat. Of course, the specific arrangement or configuration of the heat dissipating fins 510-1 may differ from that shown in this embodiment. More than one fan may be used for a given light generation module 300-5. In some aspects, the operation of fan 530 may be controlled using temperature sensing or a measure of the amount of energy supplied to LED assembly 338-2.

  Another aspect of the light generation module 300-6, including the fan 530-1, is shown in FIG. For example, a fan 530-1 such as a low decibel fan can be placed in a heat sink 540 such as a diecast heat sink. LED assembly 338-3 (the back of which is visible in FIG. 35) is thermally coupled to a heat sink 540 (eg, using a gap pad, viscous plate or liquid metal). The heat sink 540 has fins 510-2 that form channels 542 through which air flows. The LED assembly 338-3 and the chassis 336-2 that supports the secondary optical component 334-2 can be removably attached to the heat sink 540, for example, using screws. In some aspects, the LED assembly 338-3 and chassis 336-3 may be permanently attached to the heat sink 540, and the entire light generation module 300-6 that incorporates all of the components shown in FIG. Can be attached to and removed from the lighting fixture housing. The heat sink 540 can also serve as a housing or support for additional components, electronic circuitry, or the like for the light generation module 300-6.

  In one aspect of the light generation module 300-7 shown in FIGS. 36-38, the thermal components include a thermally conductive base plate 340-3, fins 510-3, and a cover 550. The components may be configured to facilitate air flow through some of the heat dissipation components (eg, fins 510-3) as shown in FIGS. For example, in some aspects, one or more fans 530-2 may be used to enhance the air flow through the channel 542-1 formed by the fins 510-3.

  The cover 550 is configured to allow the light generating module 300-7 to be screwed to the housing 304-2 of the lighting fixture 100-2 or, in some embodiments, the light generating module 300-7 to the fixture housing. The cover may be configured to allow clipping or snapping within 304-2. Cover 550 includes contacts 352-3 for operating power and / or control connectivity, or cover 550 for allowing access to power and / or control contacts on the LED subassembly. Holes may be included.

  As can be seen in FIG. 39, the mounting bracket 316 is designed to be mounted, for example, between joists, beams or similar building structures on the ceiling 560 to substantially lower the lower portion of the lighting fixture 100-2. Alternatively, the lighting fixture 100-2 may be embedded on substantially the same surface as the ceiling 560. The lighting fixture 100-2 may be configured to hold a removable light generation module (eg, light generation module 300-7). The lighting fixture 100-2 may include other components that can be disposed within the controller housing 562 in addition to the controller. The wiring section 564 may include various electronic components such as wiring for supplying operating power and data to the light generation module 100-2. The controller housing 562 and / or the wiring section 564 allows the recessed lighting fixture 100-2 with a low vertical profile to minimize the height of the recessed lighting fixture 100-2 within the ceiling 560. It may be configured to provide. In some aspects, the profile of the recessed lighting fixture 100-2 can be connected to a ceiling, for example, a two-by-four stud or beam without requiring additional space above the ceiling. It may be about 4 inches deep above 560.

  As shown in FIGS. 40 and 41, the light generation module 300-5 described with reference to FIG. 34 (or another suitable light generation module disclosed in the present specification) is further disclosed. According to another aspect, it may be used inside the implantable beam mounted lighting fixture 100-2. The recessed lighting fixture 100-2 may include a housing 304-2 and a mounting bracket 316 configured to mount the lighting fixture 100-2 on the ceiling 560 or other suitable location. The light generation module 300-5 is shown in a state removed from the recessed lighting fixture 100-2 in FIG.

  In some aspects, the light generation module 300 may not include control functions within the module, or may include a very limited amount of memory, processing, or control functions within the light generation module 300. For example, the light generation module 300 receives a drive signal for an LED from an external controller module (ie, a controller that is not located on the light generation module 300) and does not perform further control of the LED and provides feedback to the external controller module or Does not provide information.

  In some aspects, the light generation module 300 may include various memories, processing or control functions on the light generation module 300 itself. For example, the light generation module 300 may include a unique identification code such as a serial number. This serial number is available for reading by the external controller module, and the information associated with the serial number can be present in the memory associated with the controller module and / or information related to the serial number can be transferred from an external source to the controller module. It is possible to supply. In one aspect, the controller module reads the unique identification code of the light generation module 400 and accesses a database containing information specific to the light generation module 300. In some aspects, the identification code can identify groups of light generation modules 300 that have similar or identical characteristics and do not identify special light generation modules 300.

  The light generation module 300 may include only an identification code from which further information can be accessed as discussed above. Alternatively, in some aspects, the light generation module 300 may include additional information within a memory on the light generation module 300. Examples of information that can be included on the light generation module 300 include, but are not limited to, operating power requirements; operating power rated output; LED source description; light generation characteristics or parameters related to color or color temperature; There is a description of the beam angle; calibration parameters; operating temperature; controller operating instructions related to operating temperature; and historical data related to temperature, time or other light generation characteristics.

  The operating power requirement may be supplied by the light generation module 300 in place of voltage or current, and may include any other suitable information regarding the supply of power to the light generation module 300. The operating power rated output may provide the rated power in watts or lumens and may include information regarding any predicted aging. The description of the LED-based source may include the type and / or number of RGB LEDs and / or white LEDs, and color temperature specifications. In some aspects, information regarding the light beam angle and / or achievable light beam angle may be included. In some embodiments, information regarding the expected usable life span may be included. The light generation module 300 may communicate the operating temperature measurement to the controller, and in some aspects may provide data or instructions to the controller regarding the desired power level based on the operating temperature measurement. For example, the light generation module 300 may instruct the controller to reduce the power supplied to the light generation module 300 when a certain threshold operating temperature is reached. In some aspects, historical data such as the number of hours of execution time, historical operating temperature, or other data may be provided by the light generation module 300 to the controller or other suitable device. In some aspects, information and / or instructions provided by the light generation module 300 may be initiated by the light generation module 300 itself and communicated to the controller. In some aspects, the controller or other reading device may request information from the light generation module 300 or read information directly from a memory module or other suitable component of the light generation module 300.

  As shown in FIG. 42, in some embodiments, a socket 302 may be used to replace the light generating module to the lighting fixture housing or heat sink. In this embodiment, the grip ring 332 is rotatable on the molded ridge feature 580 of the chassis 336-2 and follows and engages a complementary helical path 584 on the socket 302 to socket the module. Including an embossed feature (eg, post 582) that locks onto. In some aspects, the socket 302 may include a key 586 that provides a linear docking path for engaging the light generating module with the socket 302. Key 586 prevents the light generating module (other than grip ring 332) from rotating within socket 302. In this way, rotation of the grip ring 332 does not substantially affect the orientation of the LED assembly. Furthermore, the orientation of any connector on the back side of the light generating module does not change, which allows the orientation-designating connector to be coupled with a complementary connector on the housing.

  In some embodiments, the tool on the lighting fixture of the light generating module 300 by using a post 582 on the inner surface of the grip ring 332 and a helical path 584 or threaded thread on the outer surface of the socket 302. Without installation and removal can be achieved. In this regard, the light generation module can be easily attached to the lighting fixture and thermal, mechanical and electrical connections can be automatically generated as a result of the attachment. Of course, in some aspects, the user may require one or more additional steps to make all connections to the housing of the light generation module. For example, in some embodiments, the physical and thermal coupling of the light generation module to the housing can be obtained by twisting the light generation module into a socket, as described with reference to FIG. Electrical connection to can be accomplished by separately plugging the light generating module connector into the housing connector.

  In one aspect, an electrical contact or other means may be incorporated into the socket 302 to detect that the grip ring 332 has reached the locked position and the LED hexagon unless the light generating module 300 is fully locked into the socket 302. The drive signal and / or the operating power may not be supplied to the subassembly.

  FIG. 43 illustrates one embodiment of a socket 302 attached to a heat sink 540-1 that can form a thermally conductive portion of a fixture housing. The socket 302 can be bolted or otherwise fastened to the heat sink 540-1 using the through hole 306 in the flange 308. The through hole 590 can be provided in the heat sink 540-1 with respect to the electrical connector. In some aspects, other methods of securing the socket 302 to the heat sink, housing, or lighting fixture may be used, and in some aspects the socket 302 may be integrally connected to the housing.

  In some embodiments, attachment elements other than sockets may be used to attach the light generating module to the housing. For example, in some embodiments, the light generating module may be attached to the housing using an adhesive. In some embodiments, the light generating module may be attached using fasteners such as screws or bolts, and in this method there is no socket.

  44A and 44B show an alternative embodiment of the socket 302-3, in which the stamped sheet 602 includes a locking groove 694 for receiving the post 606 of the light generating module 300-8. In order to mount the light generating module 300-8 in the socket, the post 606 is inserted into the locking groove 604 and rotated clockwise. At the end of rotation, a detent may be used to releasably lock the light generating module 300-8 to the socket 302-3. For example, one or more rounded ends 610 of the post 606 may be engaged with the raised portion 612 of the stamped sheet to provide stability to the attachment (see FIG. 45). . The bent portion 614 of the stamped sheet may be biased to push the post 606 to further ensure attachment.

  A keyed center post 620 may be used to correctly orient the contact pads 616 of the light generating module 300-8 with the leaf spring contacts 618 on the stamped sheet 602. Of course, alternatively, the contact pad 616 may be placed on the stamped sheet 602 and the leaf spring contact 618 placed on the light generating module 300-8. Other suitable connection assemblies may be used to achieve electrical and / or mechanical connections.

  46 and 47 show another alternative of the socket 302-4 and the light generation module 300-9. In this aspect, the light generation module 300-9 includes at least two flexible wings 628 that are deformable inward, thereby engaging when the light generation module is pushed into the socket. Element 630 is allowed to move inward. Once the engaging element reaches the groove 632 in the socket 302-4, the flexible wing 628 moves outward, and the engaging element engages the groove 632 to place the light generating module 300-9 in the socket 302-. 4 to hold. Spring eccentric contact plate 636 is disposed at the base of socket 302-4 and facilitates electrical connection to the light generating module. To remove the light generating module 3000-9 from the socket 302-4, the user pushes one or more flexible wings 628 inward to release the engaging element 630 from the groove 632.

  While each of the socket aspects described so far used a circular socket as an example, it is important to note that the socket need not be circular. For example, in the embodiment of socket 302-5 and light generation module 300-10 in FIG. 48, socket 302-5 is substantially rectangular. In this aspect, the light generation module 300-10 includes one or more tabs that engage corresponding compliant catches 642 in the heat sink 540-2.

One or more hangers 650 support the lighting fixture 100-4 and provide wiring conduits that carry operating power and / or control signals to the controller 105. One or more sockets 302-6 are facing upwards and include an electrical connector 310 for engaging an electrical connector on the light generation module. The light generation module can be secured to the lighting fixture by passing a screw through the light generation module and through a threaded hole 652 on the base of the socket 302-6.

  Another embodiment of a substantially rectangular socket 302-7 is shown in FIG. The light generation module 300-11, which is also substantially rectangular, includes an LED assembly 338 and "clicks" into the socket 302-7 ("snap-fits"). The light generating module 300-11 includes a spring-biased catch 660 that protrudes into a groove 662 in the socket 302-7 to hold the light generating module 300-11 in place. In some embodiments, the fastener may be locked in the equipped or unequipped position using a tool. The light generation module 300-11 also includes an orientation notch 664 that helps align the light generation module 300-11 by coupling with a corresponding protrusion 668 in the socket 302-7. The light generation module 300-11 may include a heat sink fin 510 integrated with a die cast aluminum housing. In some aspects, the heat sink fins may be incorporated into the socket 302-7 and / or the housing to which the socket is attached. Socket 302-7 includes leaf springs 670 for operating power and data connections, although any suitable connection may be used. The socket 302-7 may be attached to the lighting fixture using a through hole 306 in the socket flange 308.

  Another aspect of socket 302-8 and light generation module 300-12 is shown in FIG. In this aspect, the light generating module 300-12 includes pivot hooks 694 that extend outward when the pinch lever 696 is squeezed. In this aspect, the light generation module 300-12 is held within an extruded aluminum module housing 698.

  One aspect of the toolless light generation module 300-13 is shown in FIG. The light generation module 300-13 has an over-center latch 702 on one side. When the latch handle 704 is pulled, the hook 706 is released from the corresponding groove in the socket (not shown). The latch 702 is configured to allow a user to grip and allow the light generating module 300-13 to be installed and removed without a tool with one hand. In an alternative embodiment, a similar light generation module is free of latches but instead includes flanges at both longitudinal ends for bolting to a socket or fixture housing.

  An embodiment using mounting hardware that attaches the light generating module 300-14 to a socket or lighting fixture is shown in FIG. The light generation module 300-14 includes two through holes inside the module for inserting screws 710 or other hardware. Through holes may be disposed between the LED assemblies 338. Screws 710 are fastened into threaded holes in the socket base or elsewhere on the lighting fixture.

  Referring to FIG. 54, one aspect of the light generation module 300-15 attached to the socket 302-9 is shown. The base of socket 302-9 includes a threaded hole for receiving screw 710 that passes through a through hole in light generating module 300-15. The base of socket 302-9 also includes an electrical connector 352 for receiving a corresponding electrical connector of light generation module 300-15.

  FIGS. 55 and 56A-56E show various lighting fixtures 100-4 that provide light in an upward direction using a removable light generation module 300-15 attached to a socket 302-10 in the lighting fixture. An aspect is shown. The electrical connector is provided at the bottom of the socket base and light generation module 300-15. From the figure, it is apparent that the controller module 105 can be any of a number of configurations.

  FIG. 57 is an exploded view showing one aspect of a rectangular light generation module 300-16 including a heat dissipation fan 530-3. The light generation module 300-16 includes an acrylic faceplate 330-2, a secondary optical component 334, a set of LED assemblies 338, a die cast aluminum module housing 512-2 including a heat dissipation channel 714, and a fan 530-3. And a cover 716 for the heat dissipation channel 714. The fan 530-3 is a flat one-way fan that draws air into the module housing 512-2 through the intake 720, moves air through the heat dissipation channel 714, and through the outlet 722. Air is discharged from the module housing 512-2. A metal core printed circuit board 346 may be used as part of each LED assembly 338 to assist in the transfer of heat from the LED assembly 338 to the thermally conductive baseplate 340-4 and then to the heat dissipation channel 714.

  FIG. 58 shows one embodiment of a lighting fixture 100-5 that includes a housing 304-3 that can accommodate up to six light generation modules 300-16. In this aspect, the light generation module 300-16 is snapped into the lighting fixture 100-5 so that the operating power connection and the control signal connection engage the connector 310 located in the housing 304-3. This is done via a connector on the base of the generation module 300-16.

  In some aspects of the disclosure according to the present invention, the modular lighting fixture is configured such that the housing is attached through an opening in a building structure such as a ceiling or a hole in a wall. In this regard, lighting fixtures can be installed as an embedded fixture in an existing structure, i.e., without having to cut a ceiling, wall, or other building surface until it reaches a beam or other support element, and existing units. Can be mounted in an opening in a building surface or structure.

  In one aspect, as shown in FIG. 59, the lighting fixture 100-1 is somewhat L-shaped and configured to be mounted within a building surface such as a ceiling. Mounting cone 802 includes mounting feet 804 for supporting and securing lighting fixture 100-1 to the ceiling (or other building surface). The housing 304-1 extends in the vertical direction away from the mounting cone 802 in one direction. The housing 304-1 may include a heat dissipation element 320 (eg, a fin). Furthermore, the detail of the aspect of the lighting fixture 100-1 is demonstrated below.

  The order of attaching the lighting fixture 100-1 to the ceiling 560 is shown in FIG. Initially, the distal end 806 of the housing 304-1 is moved through the opening 812 in the ceiling 516 in the vertical direction or at an angle somewhat offset from vertical. As the distal end advances further into the space behind the ceiling, the housing 304-1 is rotated to bring the housing 304-1 closer to the horizontal. In some aspects, the proximal end 808 of the housing 304-1 is rounded to help fit through the opening 812 when rotating the housing 304-1. The mounting cone 802 is connected to the housing at the hinge 801 so that the mounting cone 802 remains substantially in contact with the opening 812 while the housing 304-1 is rotated into place. (FIG. 60 shows a mounting cone 802 that maintains the same orientation throughout the installation of the lighting fixture 100-1.) After housing 304-1 reaches a horizontal orientation, mounting cone 802 is pushed upward until flange 814 of mounting cone 802 engages the exposed surface of ceiling 560. When the lighting fixture 100-1 is first installed in the ceiling 560, the mounting legs 804 are pivoted so that they do not prevent the mounting cone 802 from being inserted into the opening 812. Once the flange 814 of the mounting cone 802 engages the exposed surface of the ceiling 560, a screwdriver is used to rotate the mounting legs 804 and then bias them downward to attach the mounting cone flange 814 and The mounting leg 804 sandwiches the ceiling 516.

A hinge 810 connecting the mounting cone 802 and the housing 304-1 can be seen at the proximal end 808 of the housing 304-1. The controller housing 818, in this aspect, is integrated into the housing 304-1 along the bottom portion of the housing. In some aspects, the controller housing 818, and thus the controller module, is thermally isolated from the housing 304-1.

  In some embodiments, the housing 304-1 may be extruded as in the embodiment shown in FIGS. As shown in FIG. 62, a through hole 822 for positioning the operating power connector and the control input connector may be located at the distal end 820 of the controller housing 818.

  Mounting hardware 826 for adjusting the mounting legs 804 is shown in FIG. Also visible in FIG. 63 is a light generation module 300 that can be replaced by the user. As with some other aspects disclosed herein, the light generation module 300 can be attached and removed by rotating a grip ring that interacts with the socket. In this regard, once installed in an opening in the ceiling (or other building surface or structure), the lighting fixture 100-1 provides the function of an unnecessary light generating module interchangeability of the tool. In some aspects, the mounting hardware 826 may be configured to allow unnecessary operation of the tool so that both the attachment of the lighting fixture 100-1 and the replacement of the light generation module 300 are tool-free.

  Instead of including an extruded fixture housing, in some embodiments, the lighting fixture 100-1 may include a die cast fixture housing 304-2. As shown in FIG. 64, the housing 304-2 and the mounting cone 802 are not hingedly connected in some aspects. Although mounting hardware 826 and mounting legs 804 similar to the embodiment shown in FIG. 59 may be used, any suitable mounting hardware and coarse landing legs may be used. The controller housing 818 may be located below and thermally insulated from the fixture housing 304-2. In some aspects, the controller module and / or controller housing 818 is thermally coupled to the fixture housing 304-2. In some aspects, the controller and / or controller housing 818 is thermally coupled to a separate heat sink (not shown). Additional perspective views of the embodiment of FIG. 64 are shown in FIGS.

  FIG. 68 shows a frame-in kit and lighting fixture for new construction attachment. A joist hanger 830 supports a support surface 832, a junction box 832, and a hanging bracket 316. In some embodiments, a controller module (not shown) may be installed in the junction box 834 instead of being placed on the bottom surface of the fixture housing. The dimensions of one embodiment of the lighting fixture 100-1 for use in a new build attachment are shown in FIGS. 69A, 69B and 69C. These dimensions are given as examples only, and other dimensions are possible.

  One aspect of the controller module 105 for modular lighting fixtures disclosed herein and other suitable lighting fixtures is shown in FIG. The controller module 105 accepts input operating power, such as “wall power” (eg, 110 V AC or 220 V AC) via the input wiring 850. Data and / or input control signals are also provided to the control module 105, which may also be supplied via the input wiring 850 as well. As an output, the controller module provides a low DC voltage and one or more control signals to the LED assembly of the light generation module via output wiring 852. As described above, the controller module 105 may further receive or exchange information that resides on the light generation module, including circuitry, memory, or processing power. For example, the controller module 105 may receive identification information from the light generation module.

  One aspect of the controller module 105 is shown in FIG. 70 along with its structural package (controller housing 818). The illustrated configurations and dimensions are by way of example only, and other sizes, shapes, and configurations can be used. In this embodiment, the controller housing 818 is constructed of stamped sheet steel or stamped sheet aluminum, although other structural materials and methods are possible. In addition to the input wiring 850 and output wiring 852, the controller module includes an indicator light 856, a flexible elastomer pull tab 858 attached to one side of the controller housing 818, and the user can properly control the controller when installing it in the housing. A visual indicator 860 may be included to assist in orienting the module. Controller housing 818 may have a curved front end 862 to facilitate insertion and removal of controller housing 818. In some aspects, the controller housing 818 may have a shape and / or element that prevents insertion of the controller housing 818 in the wrong orientation.

  71A-71C show various input interfaces for the controller module 105 that can be exchanged to select how to receive control signal inputs. In FIG. 71A, the controller module 105 includes input and output spring clips 870 that allow for zero to 10 volt control that can be coupled from the controller module to a multi-unit controller module. 71A to 71C, the input operating power is supplied to the controller module 105 via the input wiring 850. FIG. 71B shows a controller module having an RF receiver 872 and a zone selector 874. In this configuration, the controller 105 can be controlled wirelessly using radio frequency signals. The zone selector 874 allows group control and facilitates remapping. In FIG. 71C, the controller module includes an RJ-45 jack 876 that allows Ethernet-based control signals to be used as inputs. Multiple controller modules can be linked by using two jacks.

  72, 73, 74, 75 illustrate four steps in the method of attaching the controller module 105 within the recessed lighting fixture 100 that is already attached to a building structure (eg, ceiling 560).

    In the first step, as shown in FIG. 72, the controller module's output wiring 852 and input wiring 850 are connected to the associated wiring of the lighting fixture and wall power supply. Although not shown, the control input line may be connected to the control input connector 880. Controller housing 818 can be oriented with the aid of visual indicator 860. In the second step, as shown in FIG. 73, the controller module 105 is moved through an opening 884 (eg, a light emitting opening) in the fixture housing 304 and rotated in a horizontal orientation. Once in the horizontal orientation, the controller module 105 is rotated to the working orientation about the vertical axis as shown in FIG. The clamp element 888 is then used to lock the controller module in place, as shown in FIG. To remove the controller module, the process is reversed and a pull tab 858 is used to pull the controller module 105 away from the housing wall and toward the opening 884.

  In some aspects, the controller module itself is modularly configured in terms of input and output interfaces. One aspect of the modular controller module 105-1 is schematically illustrated in FIG. The controller module 105-1 includes a processor 102 (see FIG. 1) that processes input signals to determine and deliver output power and / or drive signals for controlling LED-based light sources. In some aspects, the processor 102 is located on the motherboard. More generally, the controller module includes at least a first circuit board including an input circuit 892 configured to receive an input signal including information related to lighting, and at least one output signal. Configured to allow modular attachment and removal from a second circuit board including an output circuit 896 configured to output at least one lighting control signal based at least in part on the included information. , At least one connection mechanism 894 may be included. In one aspect, the connection mechanism 894 includes at least one electrical connection between the first circuit board and the second circuit board when both the first and second circuit boards are coupled to the at least one connection mechanism. I will provide a. In an exemplary embodiment, as described above, this connection mechanism may be provided by a motherboard. In another aspect, the processor 102 is disposed on the motherboard and processes at least one input signal to provide at least one lighting control signal (eg, one or more PWM drive signals). .

  More specifically, the synonymous “front end” interface or input interface 892 provides flexibility to the user in configuring the controller module 105 for receiving control signals. For example, a user may use various input interface boards and / or connectors 894 to provide input information via Ethernet, DMX, Dali, wireless connection, analog control, or any other suitable connection. Can be done. The synonymous “back end” or output interface 896 provides flexibility to the user regarding the number of LED channels driven and / or the type of channels driven. For example, depending on the type of light generation module used, the output interface board can provide single channel / single color drive capability, or use different output interface boards for multiple colors or multiple color temperatures. Multiple channels can also be driven. In particular, in some embodiments, an output interface board may be used to drive multiple color temperature white LEDs. The output power may be sent to the LED base light source via the output wiring 852.

  According to another aspect of the present disclosure, a battery or other auxiliary power source may be provided on the LED lighting fixture so that the LED lighting fixture can be used for emergency lighting in addition to its primary lighting purpose. . For example, as shown in FIG. 77, the controller module 105 may typically be coupled to a main power source, such as a wall power supply 900, but in the event of a power loss, a rechargeable battery or a high capacity capacitor instead. The auxiliary power source 902 may be coupled. In some embodiments, a connection to an auxiliary line power source may be used as an auxiliary power source. The controller module may be configured to automatically switch to using the auxiliary power source 902 as the power source for the LED lighting fixture when the main power source is interrupted for a threshold time.
