Patent ID: 8100537

Claim:
A laser lighting apparatus comprising: a heatsink housing having an opening to allow light emanating from a coherent light source to project therethrough; a lighting device within the housing, the lighting device comprising at least one coherent light source; at least one holographic optical element, the at least one holographic optical element positioned within a light pathway of the coherent light source when power is supplied thereto; a switched-mode power supply to supply power to the coherent light source; and a proportional temperature control system to allow the coherent light source to function at sub-zero Fahrenheit temperature conditions; a printed circuit board positioned adjacent to the heatsink, the printed circuit board having components to electrically connect the coherent light source to the power supply; and, a first lens and a second lens, the first lens having an opening therethrough and affixed to the top surface of the heatsink, the second lens affixed to a bottom surface of the heatsink wherein a circumference of the first lens is smaller than an inner luminal surface of the housing.
