Abstract

A one piece heat sink LED platform body for a streetlight with an integrally formed hemispherical protuberance, a LED cluster, a lens cover, a LED driver, an array of cooling fins, and a fiber optic cable.

Claims

1. A heatsink LED platform body for a streetlight having a thickness, outside dimensions, a rear surface, and a front surface, said platform having:

a. a LED driver mounted on the rear surface;

b. an integrally formed hemispherical protuberance on the front surface;

c. an open cavity formed in said protuberance;

d. a LED light source mounted within said cavity and electrically connected to said LED driver;

e. a lens cover mounted on said cavity; and

f. an array of integrally formed cooling fins on the front surface thereof.

2. The platform of claim 1, wherein said protuberance is centrally located.

3. The platform of claim 1, wherein said body is made of a material having high thermal conductivity.

4. The platform of claim 3, wherein said material is aluminum.

5. The platform of claim 4, wherein said aluminum is alloy 6061 T6.

6. The platform of claim 4, wherein said light source is a LED light cluster.

7. The platform of claim 6, wherein said LED light cluster is either a 50 W or a 100 W EdiStar Series LED module.

8. The platform of claim 7, wherein said lens is a type 3 light distribution pattern.

9. The platform of claim 8, wherein said body has outside dimension that are standardized and made referable to a standardized street light fixture and the platform body is thereby adapted to be fitted therein for operational use.

11. A heatsink LED platform body of claim 1, for installation into standardized streetlight housing.

12. The platform of claim 1, wherein an ambient light detecting fiber optic cable is operatively connected to the LED driver to thereby control the amount of electrical power being delivered to the LED light source as a function of ambient light conditions.

10. A heatsink LED platform body having a thickness, outside dimensions, a rear surface, and a front surface, said body having:

a. an integrally formed hemispherical protuberance centrally located on the front surface;

b. an open cavity formed with said protuberance ;

c. and an array of integrally formed cooling fins.
