Embodiment Construction

[0041] The light emitting diode (LED) modules disclosed herein can be used for exterior vehicle lighting. The LED modules can be installed in the light kit socket from the side rather than from the rear. The LED module may include optical elements adapted to distribute light to a reflector that receives light from the LED chip(s) and directs the reflected light towards a viewer. Since the LED modules can be mounted from the side rather than the rear, the reflector can be more compact compared to conventional reflector designs. This is more fully disclosed in the detailed description below herein.

[0042] With typical, known rear combination lamps using light emitting diodes as light sources, there are a number of ways to ensure that the output light exits the device in the proper direction. For example, a first generation system commercially available under the name "JOULE" used light emitting diodes mounted at specific angles. The assembly process of the first generation ...

Abstract

The invention discloses a side loading LED module for rear assembled lamp mounted of assembled lamp mounted on the rear part of a motor vehicle. One or more LED are mounted on remote side of a printed circuit board with a circuit that drives the one or more LED. A circuit board and a heat yielding pad are fixed onto a heat radiator by screw thread or rivets, then the heat radiator is mounted on lateral face of an outer housing. The LED emits astigmatism in the outer housing. One surface of the outer housing is multi-faceted parabolic reflector, which receives divergent light from the LED, and reflects the collimated light beam to foreside of the outer housing vertically, and there ejaculated from the lamp through a transparent cover. Each facet on the parabolic reflector makes part of the reflected light beam off set angularly, and reflected light is collimating with angle wider than single collimated light beam.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under the provisions of Title 35, United States Code, Section 119e, of Provisional Application 61 / 056,738, filed May 28, 2008, entitled "SIDE ENTRY LED LIGHT MODULE FORAUTOMOTIVE REAR COMBINATION LAMP," with The contents thereof are incorporated herein in their entirety by reference. Thus, the full Paris Convention priority is expressly reserved. technical field [0003] The invention relates to rear combination lamps for motor vehicle lighting systems. Background technique [0004] For many years, motor vehicles have employed electric lighting for many functions. For example, lights provide forward lighting (headlights, auxiliary lights), alerting (front parking lights, rear tail lights), signaling (turn signals, hazard, brake lights, reverse lights) and convenience, just to name a few applications (Dome lighting, Instrument lighting). Historically, incandescent bulbs have been use...
