Patent ID: 8337062

Claim:
An LED lighting unit, comprising: a base plate having a side surface; a plurality of base boards aligned on the side surface of the base plate, each of the plurality of base boards including a mounting surface and an opposite surface opposite to the mounting surface, and each of the mounting surfaces aligned adjacent to the side surface in a same direction; a plurality of heat sinks located adjacent respective ones of the opposite surfaces of the plurality of base boards; a plurality of LED light sources mounted on respective mounting surfaces of the plurality of base boards in a substantially co-planar relationship, and a virtual line connecting the LED light sources being substantially normal to a light emitting direction of the plurality of LED light sources; a plurality of parabolic reflectors, each of the plurality of parabolic reflectors being adjacent to and having a space between another one of the plurality of parabolic reflectors, and each of the plurality of parabolic reflectors including a parabolic reflective surface having a focus, each focus located substantially at a respective one of the plurality of LED light sources; and at least one V-shaped reflector including two parabolic reflectors, located between adjacent ones of the plurality of parabolic reflectors, and the at least one V-shaped reflector filling the space between the adjacent ones of the parabolic reflectors, wherein a boundary between the two parabolic reflectors of the at least one V-shaped reflector extends in a linear fashion between the adjacent ones of the plurality of parabolic reflectors, the at least one V-shaped reflector reflects light emitted from the respective ones of the plurality of LED light sources that is not received by each of the plurality of parabolic reflectors, and thereby the plurality parabolic reflectors and the at least one V-shaped reflector are configured to transform light emitted from the plurality of LED light sources into a single, integrated light.
