First Claim
Patent Images
1. A headlamp, comprising:
- a housing defining an inner surface and an outer surface;
an outer light transmissive member adapted to engage with said housing, defining a three-dimensional space therebetween;
a plurality of reflector units positioned within said space;
a corresponding plurality of high-flux light emitting diodes arranged at the base of said reflector units and operatively mounted to a support member such that emitted light rays are directed away from said support member;
a plurality of inner light transmissive members adjacent to said outer light transmissive member, wherein each of said plurality of inner light transmissive members is fixedly secured to at least one alignment mechanism such that each of said plurality of inner light transmissive members corresponds to one of said plurality of light emitting diodes; and
a heat dissipating mechanism;
wherein said headlamp effectively emanates white light in any given direction.
