20100149818 | INTEGRATED LED HEAT SINK - A heat sink for use with a high output LED light source is disclosed. The heat sink is used with an LED and conical reflector. The heat sink has a cylindrical back end holding the light emitting diode. The heat sink includes a conically shaped wall having an inner and outer surface and an open front end. The open front end has a rim with notches. The reflector has a front flat surface with arms which are fixed in the notches with a fastener. The heat sink includes a plurality of slits formed on the inner and outer surfaces extending between the back and front ends. A plurality of vanes extend radially from the inner surface. The heat sink is fabricated from a thermally conductive material. The conical shape of the heat sink, the slits and vanes increases exposed surface area to assist in dissipating heat generated from the LED. | 06-17-2010 |
20100091507 | Directed LED Light With Reflector - A high intensity light is disclosed. A first circular lighting array having a plurality of reflectors and light emitting diodes is provided. A second circular lighting array is mounted on the first circular lighting array. The second circular lighting array has a second plurality of reflectors and light emitting diodes. Each reflector includes a tulip-shaped reflective surface having a symmetrical vertical cross section and a different symmetrical horizontal cross section. The reflective surface creates a uniform beam reflecting from a corresponding LED at horizontal angles relative to the reflective surface and a narrow beam in vertical angles relative to the reflective surface. | 04-15-2010 |
