[0001] The disclosure relates generally to light emitting assemblies and systems, and more particularly, the disclosure relates to a panel mounted light emitting element, assembly and system.
[0002] Recent technological advances in low voltage light sources, such as light emitting diodes (LEDs), now present low voltage light sources as suitable candidates as light sources. Low voltage light sources operate at a small fraction of the electrical power of conventionally used light sources and are an attractive option due to generally lower cost and higher efficiency than conventionally used light sources.
[0003] A specific use of an LED based light may be a small pin light emitting element assembly for spot illumination. These pin spot lights may be panel mounted for directing the illumination. In some proposed applications, the entire pin spot light assembly must be sufficiently small to fit in restricted spaces. Additionally, the light emitting assemblies must be accessible for repair or replacement. Conventional designs provide the latches outside of the lamp housing. This makes the overall size of the bezel used to mount the lamp assembly to the panel very large. The problem is that the bulky external latch configurations make the assembly less pleasing aesthetically and also make it difficult to package the light emitting assemblies in extremely tight locations. The minimization of space occupied by these light emitting assemblies is often an issue with applications, such as automotive interior lighting.
[0004] The solution is provided by a light emitting element assembly and system that are capable of being mounted in areas having restricted space and also afford easy installation and disassembly for repair, replacement and/or upgrading of individual components of the assembly as disclosed herein. The assembly includes a housing configured to receive a light emitting element therein. In addition, the assembly includes a bezel having a first set of latch arms and a second set of latch arms extending from a surface of the bezel. The bezel is configured to retain the assembly in a position relative to the panel. The assembly also includes a mounting structure having the light emitting element operably mounted therein. The first set of latch arms include at least one latch arm configured to detachably engage a surface of or within the housing and the second set of latch arms include at least one latch arm configured to detachably engage a surface of the panel.

[0029] FIG. 1 shows an exploded view of a panel mounted light emitting element assembly 100 according to an embodiment of the present disclosure. The assembly 100 includes a mounting board 101 having wires 103 in electrical communication therewith. Light emitting elements 105 may include any devices capable of providing illumination. Suitable light emitting elements 105 may include any light emitting elements 105 known for providing illumination, such as, but not limited to, light emitting diodes (LEDs), laser diodes, organic light emitting diodes (OLEDs), incandescent lights, fluorescent lights, polymer light emitting diodes, emissive phosphor lights and electroluminescent lights. Mounting board 101 may be any device, surface, structure or substrate capable of supporting, controlling and/or providing power to light emitting elements 105. Suitable structures for use as mounting board 101 include, but are not limited to printed circuit boards (PCB). In addition, wires 103 may be any configuration of wires or other power supplies. The source of power for the light emitting elements 105 is not limited to wired power, but may include batteries, photovoltaic cells or other power sources, which may or may not include wires 103. Housing 107 is configured to receive the mounting board 101 and the light emitting element 105. The housing 107 further includes flexible cantilevered legs 109 extending along distal ends of housing 107. The housing 107 may be fabricated from any suitable material, including electrically insulative polymeric material, such as acrylonitrile butadiene styrene (ABS) or other similar polymeric materials. The housing 107 further includes a lens portion 111 extending from the body of the housing. The lens portion 111 includes a substantially transparent, translucent or otherwise light distributing or dispersing material. Suitable material for the lens portion 111, includes, but is not limited to, transparent polymer, such as acrylic or polycarbonate.
[0030] Panel 113 includes an opening 115, which is disposed therethrough. The panel 113 is any surface, structure or substrate onto which a light emitting assembly 100 may be mounted. For example, the panel 113 may include a polymeric or other material sheet wherein lighting is desired on one side of the panel 113, wherein space is limited and the majority of the light emitting element structure, such as the housing 107, the mounting board 101 and the light emitting element 105, is disposed on the opposite side of the panel 113. Disposed between the housing 107 and a panel 113 is a gasket 117. While the assembly 100 is shown including gasket 117, the gasket may be omitted in certain embodiments of the disclosure. The gasket 117 may be fabricated from foam or other insulative material and provides sealing, shock/vibration resistance and/or protects the housing 107 and panel 113, particularly during installation and disassembly of the assembly 100. The assembly 100 further includes a bezel 119 having a display surface or face plate 120 and two latch arms 121 extending therefrom. The latch arms 121 are flexible cantilevered latches configured to pass through opening 115 and detachably engage a surface within housing 107. When engaged with housing 107, the bezel 119 rests against or adjacent to panel 113, wherein the engagement retains the assembly 100 in position with respect to panel 100. In other words, the latch arms 121 engage housing 107, wherein the engagement of the latch arms 121 with housing 107 provides an engagement between bezel 119 and panel 113, wherein the bezel 119 retains the positioning of the assembly 100.

As shown in FIG. 2, the bezel 119 is engaged with housing 107 through opening 115 (not visible in FIG. 2) of panel 113. The engagement of bezel 119 with housing 107 maintains the relative positioning of the assembly 100 with respect to the panel 113. During operation, the light emitting element 105 provides illumination wherein the lens portion 111 transmits or otherwise distributes the resultant light in a desired manner.
[0032] FIG. 3 shows a cutaway view of the assembly 100 of FIG. 2. As shown in FIG. 3, the mounting board 101 is engaged with housing 107. The housing 107 may include features 301 to secure the mounting board 101 with the light emitting element 105 facing downward in a direction toward housing 107. The mounting board 101 may be engaged or otherwise attached to housing 107 in any suitable manner known in the art. For example, although FIG. 2 shows a mechanical interlocking arrangement, the mounting board 101 may be affixed to housing 107 by adhesive, latches, or any other known method known for engaging PCB structures to housings 107. In addition, the positioning of light emitting element 105 is in sufficient proximity to the lens portion 111 to provide a high efficiency of light distribution into the desired locations.
[0033] FIG. 4 shows a cutaway view of the assembly 100 of FIG. 2 which is perpendicular to the view shown in Fig. 3. The latch arms 121 of bezel 119 extend through slots 401 in housing 107 and engaged a surface 403. As shown in FIG. 4, legs 109 are arranged adjacent or in proximity to latch arms 121 of bezel 119. In order to disengage bezel 119 from the housing 107, the legs 109 may be depressed inwardly for a sufficient distance to disengage the latch arms 121 from surface 403. Upon disengagement, bezel 119 may be removed via slot 401. Once the bezel 119 has been removed, the assembly 100 may be removed from panel 113 and/or disassembled for repair, replacement and/or upgrade of individual components.
[0034] FIG. 5 shows a bottom perspective view of mounting board 101. Mounting board 101 may be any device, surface, structure or substrate capable of supporting, controlling and/or providing power to light emitting elements 105.

The housing 107 further includes a lens portion 111, which is preferably fabricated from a clear polymer, such as, but not limited to, acrylic or polycarbonate. When these components are snapped together, the latch arms 121 engage housing 107 securing the housing 107 and permitting the exposure of the lens portion 111 to the space in which illumination is desired. The lens portion 111 distributes the light emitted by the light emitting element 105. In one embodiment, the lens portion is transparent and the light of the light emitting element 105 is permitted to travel through the lens portion substantially unaltered. The lens portion 111 may also be hollowed out to create yet different light patterns. The lens potion 111 may include optical features, filters or other effects that may be desirable for the particular lighting application. In addition, the surface of the lens portion 111 can be angled or made prismatic, so that various light distribution can be achieved by making simple changes to the housing 107.

The mounting board 101 may be engaged or otherwise attached to housing 107 in any suitable manner known in the art. For example, although FIG. 12 shows a mechanical interlocking arrangement, the mounting board 101 may be affixed to housing 107 by adhesive, latches, or any other known method known for engaging PCB structures to housings 107. In addition, the positioning of light emitting element 105 is in sufficient proximity to the lens portion 111 to provide a high efficiency of light distribution into the desired locations. The bezel 119 is detachably engaged with a surface 1101 of panel 113 and surface 1201 of housing 107. Specifically, the latch arms 121 of the first set 1001 elastically deflect outwardly around the housing during installation and lock or latch the housing 107 to provide retention and/or contact with surface 1201. The latch arms 121 of second set 1003 detachably engage surface 1101 of panel 113. Specifically, the latch arms 121 elastically deflect inwardly as the latch arms are directed though opening 115 of panel 113 and lock or latch the panel 113 to provide retention and/or contact with surface 1101.

In order to disengage bezel 119 from the housing 107, the latch arms 121 may be deflected manually or by force applied by a tool or by other manipulation from surface 1201. Further, the second set 1003 of latch arms 121 may be disengaged in a similar manner from surface 1101. Upon disengagement, bezel 119 may be removed from opening 115 and the assembly 100 may be further disassembled, as desired for repair, replacement and/or upgrade of individual components.
[0054] FIG. 21 shows the elongated housing 107 according to this embodiment of the disclosure. The housing 107 includes a first dimension 2100 that is approximately equal to the diameter of the lens 111. Such reduced diameter permits the positioning and placement of the housing 107 and the assembly 100 into locations having little clearance or having elongated geometries. While not so limited, latches, slots or other features may be utilized to engage mounting board 101.
[0055] FIG. 22 shows bezel 119 having a first set 1001 of latch arms 121 and a second set of latch arms 1003. As discussed above, the first set 1001 of latch arms 121 are configured to engage housing 107, wherein the latch arms 121 may be inserted into opening 115 and engage surface 1201 of housing 107 (see e.g., FIG. 20). In addition, second set 1003 of latch arms 121 are arranged to extend through opening 115 and detachably engage surface 1101 of panel 113 (see e.g., FIG. 19). As discussed above, bezel 119 may include aesthetically desirable features, such as curved or decorative surfaces that are visible when the bezel 119 is engaged to trim the lens portion 111 in addition to securing the assembly 100 onto the panel 113. Further bezel 119 may include functional features, such as alignment mechanisms, slots or other features that provide alignment, stability and/or improved mechanical properties. In addition, as shown, the latch arm 121 of first set 1001 includes a circular chamfer geometry configured to guide engagement of the lens portion of the housing.
