Light emitter sub-assemblies especially containing an array of light emitting devices (LEDs) and modules containing such sub-assemblies which provide lighting apparatuses, especially light bars for mounting on a vehicle |
摘要 |
A sub-assembly for a light-projecting module has an array of LEDs mounted on a circuit board potted in a tray at the bottom thereof by a solidified body of potting material. The body of potting material and the tray are heat-conductive and serve to dissipate heat generated by the LEDs. A light-emitting module includes the sub-assembly and a reflector. The reflector has a base which is assembled in heat-conductive relationship with the tray, so as to facilitate dissipation of heat generated by the LEDs. The reflector is a parabolic reflector which collects light from the LEDs and projects the light as a beam. The reflector contains an optical element for concentrating or diffusing the light projected from the module. The module may be assembled in a housing having an opening through which the light projects so as to provide a light bar suitable for mounting on the dash or windshield of a vehicle. A plurality of modules may be assembled around the edge of a frame which is contained in a cover of translucent material, whereby light, which may be of different colors depending upon the LEDs, is projected omni-directionally through the cover. |
