LED system and housing for use with halogen light
First Claim
1. A light assembly comprising:
- a heat sink;
said heat sink having a first side, a second side, a base and a top;
a length of printed circuit board mounted to said first side of said heat sink;
wherein said second of said heat sink includes cooling fins and air channels formed between the cooling fins;
at least one light emitting diode mounted to said printed circuit board;
a lens mounted over said printed circuit board;
a bezel connecting said projection lens and said printed circuit board to said first side of said heat sink;
a case mounted to said second side of said heat sink; and
said case enclosing a driver;
said top and said base of said heat sink includes cooling fins, the cooling fins defining air channelsa top and bottom of the bezel further comprising cooling fins with air channels formed between the cooling fins, the air channels on the bezel aligning with the air channels on the heat sink in use;
wherein air enters at either the base of said bezel, travels behind said heat sink, and exits at said top of said bezel, transferring heat away from said cooling fins.

Abstract
An LED optical light engine spotlight which can accommodate a variable number of light-emitting diodes (LEDs) is disclosed. An optical projection lens mounted in front of the LEDs merges the separate LED beams into a single beam, similar to the single beam provided by a halogen light and reflector. A heat sink provides convection cooling up to approximately 100° F. An optional fan provides additional heat dissipation for more extreme conditions. The depicted device can include a vertical tilt of over 200°. Optimally, the depicted device is designed to have a full vertical tilt range between zenith (0 degrees) to horizontal (90 degrees) to full depression (135 degrees). An optional accessory lens provides additional capabilities, including flood lenses, colored lenses and rock guards, for example. The depicted device can be hard wired or wireless. The depicted device can be adapted to many base units and/or pan and tilt platforms.
