The object of protection of the invention relates to a lighting device comprising at least one solid state light emitter, for example at least one light emitting diode.

Efforts to develop more energy efficient systems continue. Much of the electricity produced in the United States each year (some estimates are as high as 25%) is for lighting, many of which are general lighting (eg, downlights, flood lights, spotlights, and other common residential or commercial lighting products). to be. Thus, there is a continuing need to provide more energy efficient lighting.

Solid state light emitters (eg light emitting diodes) are of great interest due to their energy efficiency. It is known that incandescent bulbs are very energy inefficient light sources-about 90% of the electricity he consumes is emitted as heat rather than light. Fluorescent bulbs are more efficient (about 10 times) than incandescent bulbs, but much less efficient than solid state emitters such as light emitting diodes.

In addition, incandescent light bulbs have a relatively short lifetime, typically about 750-1000 hours, compared to the normal lifetime of a solid state light emitter, such as a light emitting diode. In comparison, light emitting diodes have typical lifetimes between 50,000 and 70,000 hours. Fluorescent bulbs generally have a longer lifetime (eg 10,000-20,000 hours) than incandescent bulbs, but typically provide less preferred color reproduction. The typical lifetime of a conventional installation is about 20 years, corresponding to the use of at least about 44,000 hours of light generating devices (based on 6 hours of use per day for 20 years). In the case where the light generating device life of the light emitter is less than the life of the installation, the need for periodic exchange is presented. The impact of the need to replace the light emitter is particularly noticeable in difficult accesses (eg arched ceilings, bridges, high-rise buildings, highway tunnels) and / or in extremely high exchange costs.

There are a number of problems presented in using solid state light emitters in lighting devices. In many cases, additional components are added to the lighting device to solve this problem. Such a problem is solved and at the same time the lighting device can be fitted in the same or substantially the same space provided for equivalent conventional lighting devices (eg, space occupied by conventional incandescent light sources and / or conventional fluorescent light sources). It is desirable to provide an illumination device comprising at least one solid state light emitter. The ability of a lighting device that includes one or more solid state light emitters to fit in a space that is similar or identical to the space that would have been occupied by a conventional device is important when retrofitting the lighting device and when installing the lighting device in a new building.

One such problem stems from the fact that the emission spectrum of any particular light emitting diode is typically concentrated around a single wavelength (as indicated by the composition and structure of the light emitting diode), which is desirable for some applications, but ( For example, it is not desirable for other uses) to provide general illumination, such divergence spectra that generally do not provide light that appears white and / or provide very low CRI. As a result, in many cases (eg, to make a device that emits light perceived as white or quasi-white, or to make a device that emits highly unsaturated light), in many cases, a light source that emits light of a different color (e.g., , One or more solid state light emitters and optionally also one or more other types of light sources, such as additional light emitting diodes, luminescent materials, incandescent lamps, etc.). There are various reasons why one or more solid state emitters can stop light divergence and / or change the intensity of its light divergence, which debalances the color output and causes the lighting device to perceive it as a different color than the color of the desired light output. Light can be emitted. As a result, in many such devices, one problem that necessitates the inclusion of additional components is that each maintains a balance of color output between light emitters that emit light of different colors to achieve the desired color output. There may be a need to provide additional circuitry that can regulate the current supplied to the solid state light emitters (and / or other light emitters).

Another such problem is that there may be a need to mix light of different colors emitted from different solid state emitters by providing additional structure to aid mixing.

One example of why one or more solid state light emitters may vary in their light divergence intensity is a temperature (eg, resulting from a change in ambient temperature and / or heating of the solid state light emitter and / or surrounding components or structures). It is a change. Some types of solid state emitters (e.g., solid state emitters that emit light of different colors) experience differences in the intensity of light divergence (if the same current is supplied) at different temperatures, and often such changes in intensity are caused by temperature As changes occur for different degrees for emitters that emit light of different colors. For example, some light emitting diodes that emit red light have very strong temperature dependence within at least some temperature ranges (e.g., AlInGaP light emitting diodes are heated by -40% by -20%, i.e. approximately -0.5 per ° C). Optical power may be reduced by%; some blue light emitting InGaN + YAG: Ce light emitting diodes may reduce optical power by about -0.15% / ° C.). Various thermal plans have been developed to dissipate at least some of the heat generated by the LEDs. See, eg, Application Note: CLD-APO6.006, entitled Cree ® , which was published at cree.com/xlamp in September 2008. XLamp ® XR Family & 4550 LED Reliability ].

Another example of why one or more solid state light emitters may vary in their light divergence intensity is aging. Some solid state light emitters (eg, solid state light emitters that emit light of different colors) experience a decrease in light divergence intensity (as long as they are supplied with the same current) as they age, and often such decreases occur at different rates. .

Other examples of why one or more solid state light emitters may vary in their light divergence intensity are damage to the solid state light emitter (s) and / or damage to the circuit that supplies current to the solid state light emitter (s).

Another problem presented in making lighting devices with light emitting diodes that often require the inclusion of additional components is that the performance of many solid state light emitters can be reduced when they are subjected to elevated temperatures. For example, many light emitting diode light sources have an average operating life of tens of years, contrasted with just months or 1-2 years for many incandescent bulbs, but the lifetime of some light emitting diodes is significantly shortened if he is operating at elevated temperatures. Can be. A general manufacturer's recommendation is that the junction temperature of a light emitting diode should not exceed 85 ° C if a long lifetime is required. In many cases, there may be a need to offset such problems by providing additional structures (or structures) to provide the desired degree of heat dissipation.

Another problem presented in making a lighting device with a light emitting diode, which often requires the inclusion of additional components, results from the relatively high light output from the relatively small area provided by the solid state emitter. Such concentration of light output can present a problem in providing a solid state lighting system for general illumination, that is, largely, large differences in luminance within a small area can be perceived as glare and disturb the user. . In many cases, there is therefore a need to provide additional structures to mix the emitted light and / or to create a perception that the emitted light is output through a larger area.

Another problem presented in making a lighting system with light emitting diodes that often requires the inclusion of additional components is that the light emitting diodes typically operate most effectively on low voltage DC currents, and the line voltage is typically much higher voltage AC. It is a current. As a result, there is often a need to provide circuitry to convert line voltages, for example from AC to DC, and / or to reduce voltage.

In addition, in some circumstances there is a need for retrofitting or installing lighting devices in circuits with conventional dimmers. Some dimmers operate based on the signal contained in the current supplied to the lighting device (eg, the duty cycle of the AC signal, for example from triac), and additional circuitry is usually needed for this.

It is possible to create a variety of lighting devices (which thereby generate heat at a variety of different rates) and to solve the effects attributable to such different rates of heat generation (including elevated rates of heat generation). It is desirable to be able to make such lighting devices in a wide variety of shapes and sizes, and / or to correspond to conventional lighting devices.

There is a conventional lighting device having a light intensity output and / or a power input that requires a wide variety of circuits to provide equivalent output from a lighting device comprising one or more solid state light emitters, and can provide such light intensity output. It is desirable to be able to easily make various solid state light emitter lighting devices that can be powered by and / or powered by such a power input.

According to one aspect of the object of protection of the invention, there is provided a light engine module comprising at least a first solid state light emitter support member and at least a first solid state light emitter mounted on the first solid state light emitter support member. The light engine module may be inserted into one of a wide variety of lighting device elements (which may each include one or more lighting device components) to make the lighting device.

According to this aspect of the subject matter of the invention, multiple light engine modules corresponding to a single design can be made, which modules then form lighting devices comprising similar light engine modules of different shape and / or size but similar. Can be incorporated into a variety of different lighting device elements (some or all of which may correspond to the conventional shape and size of the conventional lighting device, ie the “shape factor”).

Alternatively, according to this aspect of the subject matter of the invention, it comprises a solid state light emitter of (e.g., different type (and / or number) of different types), each corresponding to a different design, and / or light of different hue or color temperature. Multiple light engine modules can be made, and / or emit light of different intensities, and / or have different types of compensation circuits, the different modules can then be of the same shape and size (and possibly Are other features) and can be integrated into lighting device elements corresponding to a single design to form lighting devices having different light engine modules.

Alternatively, according to this aspect of the subject matter of the invention, it comprises a solid state light emitter of (e.g., different type (and / or number) of different types), each corresponding to a different design, and / or light of different hue or color temperature. Multiple light engine modules can be made, and / or emit light of different intensities, and / or have different types of compensation circuits, the different modules can then be of different shapes and / or sizes (and Possibly other features) and can be integrated into lighting device elements of different shapes and / or sizes to form lighting devices having different light engine modules.

Furthermore, according to this aspect of the subject matter of the invention, different designs (eg comprising different types of solid state emitters, and / or emitting light of different hue or color temperature, and / or light of different intensities) Multiple light engine modules), and / or having different types of compensation circuits, may be provided, and multiple designs of different designs (eg, having different shapes and / or sizes, and / or other different features). Lighting device elements may be provided, some or all of the different light engine modules may be interchangeable, some or all of the different lighting device elements may also be interchangeable, wherein different designs for the entire lighting device The number of can be as many as the product of the number of different light engine modules and the number of different lighting device elements.

According to one aspect of the subject matter of the invention, some are referred to herein (such as A lamps, such as A19 bulbs, or standard fluorescent tubes, etc.), and existing shape factors of conventional lighting devices, such as those skilled in the art. There is provided a light engine module that can be used in one of a wide variety of shape factors known to the art. In other words, the light engine module can be inserted into one of a wide variety of other lighting device elements to provide a lighting device that corresponds to the shape factor of a conventional lighting device.

According to another aspect of the subject matter of the invention, a light engine module that can be used to replace a module included in a lighting device of the type described in the previous paragraph, ie a lighting device comprising at least one lighting device element and a light engine module. This is provided. Such replacement can be performed if the module burns out or becomes less efficient or if different colors or performance are required.

As described above, one very attractive feature of solid state lighting is its efficiency and its low operating cost. However, the property of solid state lighting that limits its use is its installation cost. One way to make solid state lighting more attractive is to extend the already good service life of at least some of the components of a lighting device that employs solid state lighting, with the cost of the installation over time compared to other lighting options. By much less.

In many cases, the installation cost for solid state lighting is approximately 1/3 power conversion, 1/3 light emitting diode, and 1/3 mechanical part.

As described above, solid state lighting devices typically degrade over time, but such degradation generally takes much longer to occur than in other lighting options such as incandescent and fluorescent lights. Such degradation is typically faster when the solid state light emitter (s) in the solid state lighting device are subjected to higher temperatures.

According to another aspect of the object of protection of the invention, there is provided a lighting device comprising a support member, for example equipped with at least one solid state light emitter, comprising a removable light engine module. In such lighting arrangements, whenever required or when deemed necessary, it is possible to periodically replace the support member (with one or more solid state light emitters mounted thereon) according to a predetermined schedule. In that way, the lifetime of the other components of the lighting device can be extended, and / or the lighting device can be operated at a higher temperature (ie to generate more light) than is possible, and / or Different color output may be achieved by replacing one or more support members (with solid state light emitters or solid state light emitters mounted thereon).

For example, while satisfying a given lighting requirement (e.g., the overall brightness within a particular space, such as a dining area in a restaurant), the equipment cost is at least one solid in order to use fewer lighting devices and compensate for fewer lighting devices. It can be reduced by supplying higher current to the state light emitter. In such a case, the higher operating temperature generated by operating the at least one solid state light emitter at a higher current may cause the solid state light emitter to degrade more quickly (mainly due to deterioration of the encapsulant), but the effect of such degradation It is appreciated that can be solved by replacing the light engine module (including one or more solid state light emitters that are part of the module) at the onset of degradation (or at any other stage of degradation).

Alternatively or additionally, the equipment cost is such that one or more solids whose effect of the faster degradation of at least one solid state light emitter resulting from such high operating temperatures is part of the module at the onset of degradation (or at any other stage of degradation). Recognizing that it can be solved by replacing a light engine module (or one or more of the plurality of light engine modules), including a state light emitter, below a threshold level that is generally considered to be unacceptable to deterioration of at least one solid state light emitter. It may be reduced (or further reduced) by removing one or more radiator elements provided to maintain the operating temperature of the at least one solid state light emitter at a level maintained at.
