Description

Push-pull SSL module and socket
FIELD OF THE INVENTION
The present invention is generally related to the field of lighting application design. In particular, the present invention relates to a lighting module receivable in a socket element.
BACKGROUND OF THE INVENTION
Light-emitting diodes (LEDs) intended for indication purposes have been used for a long time, but high-brightness LEDs, e.g. LEDs having a brightness that is high enough to enable general illumination of various locations such as rooms, have in a short period of time caused a significant growth in the LED and lighting applications market. High brightness LEDs are generally associated with a small size, a relatively high efficacy (and associated low temperature), a relatively long lifetime, a wide color gamut and ease of control. Naturally, such LEDs are of importance to lighting designers in developing new lighting applications.
The dominating conception in the lighting applications market today seems to be that the lifetime of LEDs is very long, on the order of 5· 104 hours, and do not break down prematurely. Thus, most lighting fixture designs are such that if the light source fails, the entire fixture needs to be replaced. However, similar to other types of light sources a LED may show early or premature failure. In addition, in some applications (e.g. shops, restaurants, and bars) the refurbishment cycles are shorter than the specified LED lifetime of 5- 104 hours, whereas in other applications (e.g. outdoor, street, office, and hospital) the LED lifetime is shorter than the refurbishment cycle. Furthermore, it may be desirable to replace LEDs prematurely (i.e. prior to failure) due to desire to change brightness, color or the like of light emitted by the lighting fixture. Thus, an arrangement that enables easy replacement of the LEDs in the lighting fixture is desirable.
US 2009/0207609 Al discloses socket arrangements for releasably mounting LEDs and light fixtures or assemblies employing such sockets. In particular there is disclosed a socket for releasably mounting an LED lamp comprising an LED chip in a package, the socket comprising socket power contacts for contacting lamp power contacts on the LED lamp and supplying power to the LED chip and a mechanism for maintaining the socket power contacts in electrical contact with the electrical contacts during operation. The mechanism comprises a spring biased tray which can be depressed with finger pressure to replace the LED lamp, and which tray when not depressed provides a spring force to bias the socket power contacts against the lamp power contacts of the LED lamp in the tray.
SUMMARY OF THE INVENTION
It is with respect to the above considerations and others that the present invention has been made. The present invention seeks to mitigate, alleviate or eliminate one or more of the above-mentioned deficiencies and disadvantages singly or in combination. In particular, it would be desirable to achieve a light-emitting lighting module that can be mounted in a socket element, which lighting module facilitates insertion of and/or retrieval of the lighting module into and from the socket element, respectively. It would be desirable to achieve a light-emitting lighting module that can be received in a socket element, which lighting module can be inserted in and/or retrieved from the socket element in a manner that is relatively easy for the user to understand and/or is intuitive (i.e. relatively straightforward) for the user.
To achieve this, a light-emitting lighting module and a light-emitting device having the features as defined in the independent claim are provided. Further advantageous embodiments of the present invention are defined in the dependent claims.
In the following, the wordings "light-emitting lighting module" and "lighting module" will be used interchangeably.
According to a first aspect of the present invention, there is provided a light- emitting lighting module that is arranged to be mounted in a socket element. The light- emitting lighting module comprises a coupling mechanism for releasably coupling the lighting module with the socket element. The coupling mechanism comprises at least one coupling element having a first resilient member. The first resilient member comprises an engaging section for engaging with a receiving portion on the socket element. The engaging section is arranged to engage with the receiving portion such as to apply pressure on the receiving portion to impede movement of the lighting module in at least one direction.
By the arrangement of the engaging section of the first resilient member such as to, when the engaging section engages with the receiving portion, apply pressure on the receiving portion such that movement of the lighting module in at least one direction is impeded, there is enabled facilitation of inserting the lighting module in and/or retrieving the lighting module from the socket element.
Specifically, the said arrangement enables that the lighting module can be retrieved from the socket element, e.g. for replacing the lighting module with another lighting module, in a pull-out fashion. Thus, additional operations such as twisting the lighting module out of a locking position in the socket element, opening a lock or similar operations for facilitating or even enabling removal of the lighting module from the socket element may not be necessary. This further entails that less space in the vicinity of the lighting module (and socket) may be required for the user to be able to, or efficiently and/or securely, seize the lighting module with his or her hand in order to remove the lighting module from the socket element. In turn, this may enable eliminating or reducing a need to remove any secondary optics such as one or several lenses, mirrors, reflectors, beam shapers and/or color mixers, etc., arranged on a lighting fixture in which the lighting module is arranged before the lighting module can be replaced with another.
Specifically, the said arrangement enables that the lighting module can be inserted into the socket element in a push-in fashion, without the requirement of additional operations such as twisting the lighting module into a locking position in the socket element, securing a lock or similar operations.
Thus, the lighting module may be inserted into and/or retrieved from the socket element using a single-hand operation.
By the said arrangement no special insertion and/or retrieval tools may be required.
Thus, by the said arrangement the insertion of the lighting module into and/or removal of the lighting module from the socket element may be relatively easy for the user to understand and/or intuitive (i.e. relatively straightforward) for the user.
As additional operations for retrieval and/or insertion as discussed above may not be necessary, the form factor ('footprint') of the lighting module and/or the socket element may be relatively small. In turn, this may enable or facilitate accommodating additional components for driving or controlling the lighting module, for example additional electrical channels or contacts for powering light emitter channels such as light-emitting diode (LED) channels, which may be required for achieving adjustable white color (e.g. with regards to color point) or even adjustable color of light emitted by the lighting module. In addition to the coupling element described above, the coupling mechanism may comprise additional means for effectuating a releasable coupling between the lighting module and the socket element.
The lighting module may comprise a material having a relatively high thermal conductivity for providing a thermal path from any light-emitting element arranged in or on the lighting module away from the lighting module, for example to a heat sink that can be coupled to the lighting module. The heat sink may be comprised in a lighting fixture or a light-emitting device as described in the following. For example, the lighting module can comprise a metal core printed circuit board.
The light-emitting lighting module may comprise an electrical connector module for coupling with an electrical connector module of the socket element, wherein the electrical connector module is at least partly constituted by the first resilient member.
In other words, electrical contact means of the lighting module may have an integrated spring function, which may effectuate a releasable coupling between the lighting module and the socket element such as described in the foregoing. By such a configuration the number of components required for assembly of the lighting module may be decreased, which in turn may lead to lower costs for manufacturing the lighting module.
The electrical connector module of the lighting module, or the electrical connector module of the socket element, may be configured such that it matches or facilitates matching with the electrical connector module of the socket element or the electrical connector module of the lighting module, respectively.
The first resilient member may be arranged such as to be biased against the receiving portion on the socket element. Such a configuration may facilitate adapting the strength of the releasable coupling between the lighting module and the socket element according to user and/or capacity requirements.
The lighting module may comprise a lighting module release actuator arranged such as to, when activated, engage the at least one coupling element such as to mitigate the pressure applied by the engaging section on the receiving portion, whereby the coupling between the lighting module and the socket element is released, such that movement of the lighting module in at least one direction is facilitated.
Alternatively or optionally, the lighting module release actuator may be arranged such as to, when activated, cause the lighting module to be displaced a
predetermined distance away from a mounted position in the socket element. The direction and/or magnitude of the displacement may be such that it becomes easier for a user to seize the lighting module with his or her hand in order to remove the lighting module from the socket element. In other words, the lighting module actuator may be arranged such as to enable or facilitate a push-eject fashion of retrieving the lighting module from the socket element.
The lighting module release actuator may for example comprise a resilient member such as a spring element.
The lighting module may comprise a light-emitting unit.
The lighting module may comprise a thermal interface for transporting heat generated by the light-emitting unit away from the lighting module.
The engaging section of the first resilient member may be arranged to engage with the receiving portion of the socket element such as to apply pressure on the receiving portion to impede movement of the lighting module in at least one direction by a resulting elastic force acting on the socket element. The thermal interface may be positionally arranged such that, as a result of the elastic force acting on the socket element, a predetermined pressure is applied on at least a portion of the thermal interface.
The lighting module may comprise at least one second resilient member positionally arranged such as to apply pressure on the at least a portion of the thermal interface. Alternatively or optionally, the at least one second resilient member may be positionally arranged such that pressure is applied throughout the thermal interface (e.g., so that pressure is applied more homogeneously, or evenly, throughout the thermal interface). By each of these configurations, an efficiency of a thermal path between the light-emitting unit and a component coupled to the thermal interface such as to receive heat therefrom, such as a heat sink, may be increased with regards to heat transfer through the thermal path.
The light-emitting unit may for example comprise at least one LED, which may be organic or inorganic, a multi-die LED unit comprising a plurality of LED dies and/or any other solid-state light source (i.e. a light source emitting light by means of solid-state electroluminescence) .
A multi-die LED unit as described above can be used 'bare' or with a cover for protecting the LED unit itself, facilitating handling of the LED unit and/or providing an interface to the LED unit to other components of the lighting module or a light-emitting device comprising the lighting module.
The light-emitting unit may comprise at least one optical element adapted to at least reflect, focus, redirect and/or modify wavelength of light emitted by the light-emitting unit. The at least one optical element may for example comprise one or several lenses, mirrors, reflectors, beam shapers and/or color mixers, etc.
The engaging section may be arranged to engage with the receiving portion such as to apply pressure on the receiving portion to impede movement of the lighting module in at least one direction by a resulting elastic force acting on the socket element. The coupling element may comprise a first surface portion on which the first resilient member is arranged and a second surface portion situated on an opposite side of the coupling element relatively to the first surface portion. The elastic force may cause the second surface portion to engage with the socket element to impede movement of the lighting module in at least one direction.
At least one of the first and a second resilient member may for example comprise a (pressure) spring.
According to a second aspect of the present invention, there is provided a light-emitting device comprising a light-emitting lighting module, a socket element and a coupling mechanism. The coupling mechanism is arranged to releasably couple the lighting module with the socket element. The coupling mechanism comprises at least one coupling element having a first resilient member arranged on the lighting module. The first resilient member comprises an engaging section for engaging with a receiving portion on the socket element, wherein the engaging section is arranged to engage with the receiving portion such as to apply pressure on the receiving portion to impede movement of the lighting module in at least one direction.
With respect to the first and/or second aspect of the present invention as described above, the engaging section may for example be arranged to engage with the receiving portion such as to apply pressure on the receiving portion, such that movement of the lighting module in at least one direction is impeded by a resulting elastic force acting on the socket element.
The light-emitting device may comprise an electrical connector module arranged on the lighting module for coupling with an electrical connector module arranged on the socket element, wherein the electrical connector module arranged on the lighting module is at least partly constituted by the first resilient member.
In other words, electrical contact means of the lighting module may have an integrated spring function, which may effectuate a releasable coupling between the lighting module and the socket element such as described in the foregoing. By such a configuration the number of components required for assembly of the lighting module may be decreased, which in turn may lead to lower costs for manufacturing the lighting module/light-emitting device.
The lighting module of the light-emitting device may comprise a light- emitting unit.
The lighting module of the light-emitting device may comprise a thermal interface for transporting heat generated by the light-emitting unit away from the lighting module.
The light-emitting device may comprise a heat sink positionally arranged such as to receive heat from the thermal interface.
The thermal interface may for example comprise a compressible material and/or a resilient material such as silicone. By such a configuration the capacity of a thermal path between the light-emitting unit and a component coupled to the thermal interface such as to receive heat therefrom, such as a heat sink as described above, with regards to efficiency of heat transfer via the thermal path may be less sensitive to irregularities or particles such as dirt situated between the thermal interface and the component (e.g., a heat sink). Thus, such a configuration may enable the thermal interface to shape around surface irregularities (such as particle contamination) on a component coupled to the thermal interface such as a heat sink, and may provide an interface which is robust against scratches and dust.
The thermal interface may for example comprise a metal film with silicon adhesion.
According to another example, the thermal interface may comprise a silicone layer or a silicone member or another member comprising a resilient material and a layer comprising material exhibiting a relatively low friction, such as aluminum foil, arranged on a side of the member comprising a resilient material.
The present invention relates to all possible combinations of features recited in the claims.

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplifying embodiments of the invention are shown. This invention may however be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will convey the scope of the invention to those skilled in the art. Furthermore, like numbers refer to like or similar elements throughout.
Referring now to Fig. 1, there is shown a schematic perspective view of a lighting module 100 according to an exemplifying embodiment of the present invention and a socket element 110 that the lighting module 100 is arranged to be mounted in.
The lighting module 100 comprises a coupling mechanism, generally referenced by the reference numeral 102, for releasably coupling the lighting module 100 with the socket element 110. The coupling mechanism 102 comprises a coupling element 104 having a first resilient member 106 with an engaging section 108 for engaging with a receiving portion 112 on the socket element 110. The engaging section 108 is arranged to engage with the receiving portion 112 such as to apply pressure on the receiving portion 112 to impede movement of the lighting module 100 in at least one direction.
The at least one direction may for example comprise the direction of insertion and/or retrieval of the lighting module 100, i.e. upwards and/or downwards, respectively, in Fig. 1.
The lighting module 100 comprises a light-emitting unit 118 adapted to emit light. The light-emitting unit 118 comprises a number of light-emitting diodes (LEDs).
Generally, the light-emitting unit 118 may for example comprise at least one LED, a multi- die LED unit comprising a plurality of LED dies, or any other solid-state light source.
In accordance with the embodiment depicted in Fig. 1, the engaging section 108 may be arranged to engage with the receiving portion 112 such as to apply pressure on the receiving portion 112, such that movement of the lighting module 100 in at least one direction is impeded by a resulting elastic force acting on the socket element 110. In this regard, the coupling element 104 comprises a first surface portion 11 la on which the first resilient member 106 is arranged and a second surface portion 11 lb situated on an opposite side of the coupling element 104 relatively to the first surface portion 111a facing the viewer in Fig. 1, wherein the elastic force causes the second surface portion 11 lb to engage with the socket element 110 to impede movement of the lighting module 100 in at least one direction. The portion of the socket element 110 with which the second surface portion 11 lb is caused to engage is not shown in Fig. 1.
The lighting module comprises an electrical connector module for coupling with an electrical connector module 116 of the socket element 110. According to the embodiment depicted in Fig. 1, the electrical connector module of the lighting module 100 is at least partly constituted by the first resilient member 106.
Referring now to Fig. 2a, there is shown a schematic perspective view of a light-emitting device 200 according to an exemplifying embodiment of the present invention. The light-emitting device 200 comprises a light-emitting lighting module 220 and a socket element 210. The lighting module 220 is arranged to be mounted in the socket element 210. Fig. 2a depicts a scenario where the lighting module 220 is mounted in the socket element 210.
The lighting module 220 comprises a light-emitting unit 228 adapted to emit light and a thermal interface 229 for transporting heat generated by the light-emitting unit 228 away from the lighting module 220. The socket element 210 comprises an electrical connector module 216 for coupling with an electrical connector module of the lighting module 220 (not shown in Fig. 2a).
The light-emitting device 200 comprises a heat sink 232 positionally arranged such as to receive heat from the thermal interface 229 of the lighting module 220.
With reference to Fig. 1, the engaging section 108 may be arranged to engage with the receiving portion 112 of the lighting module such as to apply pressure on the receiving portion 112, in such a way that movement of the lighting module in at least one direction is impeded by a resulting elastic force acting on the socket element.
With further reference to Fig. 2a, the thermal interface 229 may be positionally arranged such that, as a result of an elastic force such as described above acting on the socket element 210, a predetermined pressure is applied on at least a portion of the thermal interface 229.
Alternatively or optionally, in accordance with the embodiment depicted in Fig. 2a, the lighting module 220 can comprise a second resilient member 236 positionally arranged such as to apply pressure on the portion of the thermal interface 229. The second resilient member 236 may be positionally arranged such that pressure is applied throughout the thermal interface 229, e.g. such that pressure is applied substantially evenly over the portion of the thermal interface 229. By such configurations, the capacity of a thermal path between the light-emitting unit 228 and the heat sink 232 coupled to the thermal interface 229 such as to receive heat therefrom with regards to efficiency of heat transfer via the thermal path may be improved.
The light-emitting device 200 may comprise additional components that are not illustrated in Fig. 2a, such as a housing, electrical circuits for supplying power, etc. As important as such additional components may be, they are not essential to embodiments of the present invention and are therefore not described further with reference to the drawings.
Referring now to Figs. 2b and 2c, there are shown schematic perspective views of a light-emitting device 200 according to another exemplifying embodiment of the present invention.
The light-emitting device 200 comprises a light-emitting lighting module 220 and a socket element 210. The lighting module 220 is arranged to be mounted in the socket element 210. Fig. 2b depicts a scenario where the lighting module 220 is to be mounted in the socket element 210, whereas Fig. 2c depicts a scenario where the lighting module 220 is mounted in the socket element 210. The lighting module 220 comprises a light-emitting unit 228 adapted to emit light. The light-emitting device 200 comprises a heat sink 232 positionally arranged such as to receive heat from a thermal interface (not shown in Figs. 2b and 2c, see Fig. 2a) of the lighting module 220.
By a configuration such as depicted in Figs. 2b and 2c, an improved thermal path between the light-emitting unit 228 and the heat sink 232 with regards to efficiency of heat transfer via the thermal path may be achieved.
The lighting module 220 depicted in Figs. 2b and 2c may comprise additional components such as described with reference to Fig. 2a. However, since such additional components have already been described in the foregoing with reference to Fig. 2a, such additional components are not described further with reference to Figs. 2b and 2c.
Referring now to Fig. 3a and 3b, there are shown schematic perspective views of light-emitting devices 300 according to exemplifying embodiments of the present invention, respectively.
The light-emitting device 300 comprises a lighting module 320, a socket element 310, a light-emitting unit 328 and a heat sink 332. These components are identical or similar to the respective components described with reference to Fig. 1 and/or Figs. 2a-c, and are therefore not described further with reference to either of Figs. 3a and 3b.
The light-emitting device 300 may comprise at least one optical element adapted to at least reflect, focus, redirect and/or modify wavelength of light emitted by the light-emitting unit 328. Two specific examples are provided with reference to Figs. 3a and 3b.
With reference to Fig. 3a, the light-emitting device 300 comprises an optical element 334 comprising a reflector unit 334 adapted to reflect light emitted by the light- emitting unit 328.
With reference to Fig. 3b, the light-emitting device 300 comprises an optical element 334 comprising a clear bulb 334a and a so-called remote emitter 334b located within the bulb 334, which remote emitter 334b is capable of emitting light having a spatial intensity distribution similar to an incandescent light source. In this context, by the term "remote emitter" it is meant a light emitter such as one or more LEDs, a light guide, and a reflector, wherein the light emitting region of the light emitter is substantially shifted or replaced to an end of the light guide at which the reflector is arranged.
The optical element 334 may be coupled to the lighting module 320 and/or to the socket element 310. Referring now to Fig. 4, there is shown a schematic block diagram of a lighting module 420 according to an exemplifying embodiment of the present invention and a socket element 410 that the lighting module 420 is arranged to be mounted in.
The lighting module 420 comprises a coupling mechanism 402 for releasably coupling the lighting module 420 with the socket element 410. The coupling mechanism 402 comprises a coupling element 404 having a first resilient member 406 with an engaging section 408 for engaging with a receiving portion 412 on the socket element 410. The lighting module 420 comprises an electrical connector module 407 for coupling with an electrical connector module 416 of the socket element 410. These components are similar or identical to the respective components described with reference to Fig. 1 and/or Figs. 2a-c, and are therefore not described further with reference to Fig. 4.
With further reference to Fig. 4, the lighting module 420 comprises a lighting module release actuator 419 arranged such as to, when activated, engage the at least one coupling element 404 such as to mitigate the pressure applied by the engaging section 408 on the receiving portion 412, whereby the coupling between the lighting module 420 and the socket element 410 is released such that movement of the lighting module 420 in at least one direction is facilitated.
Such a lighting module release actuator can for example comprise a resilient member such as a spring that can be actuated by means of a button integrally arranged in the lighting module, which resilient member is at least arranged to engage the coupling element such as to mitigate the pressure applied by the engaging section on the receiving portion.
According to one example the socket element may be arranged on the light- emitting device such that it is pivotable, for example such that the socket element can be turned from a first position by about 90° (or by another angle) into another position. Such a configuration may facilitate insertion of the lighting module into the socket element and/or removal of the lighting module from the socket element, and/or increase flexibility with regards to design of the socket element and/or light-emitting device, depending on the particular geometrical arrangement of the light-emitting device.
For example, the socket element can be turned about 90°, after which the lighting module is inserted into the socket element, and subsequently the socket element is turned back to its original position. This may enable additional design possibilities for installing or mounting the lighting module into the socket element.
The electrical connector module of the socket element and the electrical connector module of the lighting module as depicted in the drawings comprise two electrical contacts (e.g. anode and cathode). However, this is not to be regarded as limiting - the electrical connector module of the socket element and/or the electrical connector module of the lighting module may alternatively or optionally comprise other electrical contacts, for example for providing additional electrical channels or contacts for powering light emitter channels such as LED channels, which may be required for achieving adjustable white color (e.g. with regards to color point) or even adjustable color of light emitted by the lighting module. According to other examples the electrical connector module of the socket element and/or the electrical connector module of the lighting module may alternatively or optionally comprise other electrical contacts or connectors for communication of control signals, data packets, etc. between the lighting module and the socket element, for example for controlling light emission of the lighting module, measuring light emission levels, etc.
A lighting module and/or a socket element such as described in the foregoing may comprise additional equipment such as power supply electrical circuits, an LED driver, a temperature sensor/feedback circuit for dimming or switching off illumination by the lighting module when sensed temperature exceeds a predetermined threshold, etc. (Such additional equipment is not shown in the drawings.)
For example, a temperature sensor/feedback circuit may be utilized to protect against cases where sufficient heat dissipation from the light-emitting unit for some reason does not take place, thereby putting the lighting module at risk of failure and/or damage due to excessive temperatures.
The height of the lighting module may not be fixed or limited by the socket element and therefore the height of the lighting module may be adapted towards desired functionality. The additional space can for instance be used to integrate LED driver electronics into a lighting module comprising a LED-based light-emitting unit, add beam shaping optics (static and/or dynamic), add wireless communication, create a means to connect a reflector, add buttons for configuration of the lighting module (static and/or dynamic), create a means for protection, etc. The size of the lighting module can also be reduced by removing electronics to create a lighting module that is substantially flat. This flexibility enables the lighting module to be adapted to many different lighting applications. For example, in applications such as track lighting, a low AC or DC voltage may be supplied at an electrical interface between the socket element and the lighting module by providing a converter for converting the 230 V AC to an LED current outside the lighting module, thereby enabling a lighting module having a relatively small size. Further, providing LED driver electronics in the lighting module may be advantageous for future readiness and in case of failure of electronics.
In conclusion, there is disclosed a lighting module arranged to be mounted in a socket element. The lighting module comprises a coupling mechanism for releasably coupling the lighting module with the socket element. A first resilient member with an engaging section for engaging with a receiving portion on the socket element is provided, wherein the engaging section is arranged to engage with the receiving portion such as to apply pressure on the receiving portion to impede movement of the lighting module in at least one direction.
Although exemplary embodiments of the present invention have been described herein, it should be apparent to those having ordinary skill in the art that a number of changes, modifications or alterations to the invention as described herein may be made. Thus, the above description of the various embodiments of the present invention and the accompanying drawings are to be regarded as non-limiting examples of the invention and the scope of protection is defined by the appended claims. Any reference signs in the claims should not be construed as limiting the scope.
