Light emitting diode perimeter lamp assembly
View Patent ↗A light emitting diode perimeter lamp assembly generally includes a housing a receiving pocket formed therein for receiving a circuit board with a plurality of light emitting diodes mounted thereon. In addition, a culminating lens having a plurality of light directing elements is positioned within the receiving pocket of the housing above the circuit board such that light emitted from said plurality of light emitting diodes passes through said plurality of light directing elements. An outer lens is also mounted over the receiving pocket. When the perimeter lamp is installed on a truck body, the bottom side of the lamp housing is at an acute angle to a ground surface while the back end of the perimeter lamp is adjacent and parallel to a truck wall such that light emitted by the plurality of light emitting diodes is projected onto the ground surface adjacent to the truck wall.

5. The perimeter lamp assembly of claim 1 wherein the front end of the housing includes a cutout portion and the lens includes a projection for fitting within the cutout such that light may project through the lens at the cutout portion of the front end.
6. The perimeter lamp assembly of claim 1 wherein the lens further includes an vent hole covered by a breathable vent patch.
7. The perimeter lamp assembly of claim 1 where in the angle between the bottom side of the housing through which light is projected and the ground is between 10 and 15 degrees.
8. The perimeter lamp assembly of claim 1 wherein the light emitted by the plurality of light emitting diodes onto the ground surface extends outward 5-6 feet from the truck wall.
9. The perimeter lamp assembly of claim 1 wherein the lens includes pillow optics.
10. The perimeter lamp assembly of claim 1 wherein said lens includes an edge flange that extends into a groove formed in the bottom end of housing such that said lens covers and seals the receiving pocket.
11. A perimeter lamp assembly for use in a truck having a trailer body with opposing side walls, each of the side walls having a top end and a bottom end, said perimeter lamp assembly comprising:
a housing having a back end adapted to be affixed to one of said opposing side walls of the truck, a front end, a bottom side extending at an upward angle from said back end and a top side parallel to said bottom side and extending at an upward angle from said back end, said top side having a plurality of fins extending therefrom;
a circuit board adapted to fit within the bottom side of the housing;
a plurality of light emitting diodes mounted on the circuit board;
a collimator having a plurality of light directing elements, said collimator being mounted above the circuit board such that light emitted from said plurality of light emitting diodes passes through said plurality of light directing elements;
a lens mounted over the bottom side of the housing; and
wherein the bottom side of the housing is at an acute angle to a ground surface when the back end of the housing is affixed to and parallel to said opposing side wall such that light emitted by the plurality of light emitting diodes is projected onto the ground surface adjacent to the truck wall.
12. The perimeter lamp assembly of claim 11 further comprising a light blinder positioned between the plurality of light emitting diodes and the back end of the housing.
13. The perimeter lamp assembly of claim 11 wherein the front end of the housing includes a cutout portion and the lens includes a projection for fitting within the cutout such that light may project through the lens at the cutout portion of the front end.
14. The perimeter lamp assembly of claim 11 wherein the lens further includes an vent hole covered by a breathable vent patch.
15. The perimeter lamp assembly of claim 11 where in the angle between the bottom side of the housing through which light is projected and the ground is between 10 and 15 degrees when said back end of the housing is affixed to and parallel to said opposing side wall.
16. The perimeter lamp assembly of claim 11 wherein the lens includes pillow optics.
17. The perimeter lamp assembly of claim 11 wherein said lens includes an edge flange that extends into a groove formed in the bottom end of housing such that said lens covers and seals the bottom end of the housing.
18. A perimeter lamp assembly for use in a truck having a trailer body with opposing side walls, said perimeter lamp assembly comprising:
a housing having a back end adapted to be affixed to one of said opposing side walls of the truck, a front end, a bottom side with a receiving pocket formed therein, said bottom side extending at an upward angle from said back end, and a top side parallel to said bottom side and extending at an upward angle from said back end, said top side having a plurality of fins extending therefrom;
a circuit board adapted to fit within the receiving pocket of the housing;
a plurality of light emitting diodes mounted on the circuit board;
a collimator having a plurality of light directing elements, said collimator being mounted above the circuit board such that light emitted from said plurality of light emitting diodes passes through said plurality of light directing elements;
a lens mounted over the receiving pocket of the bottom side of the housing; and
wherein the bottom side of the housing is at an acute angle to a ground surface when the back end of the housing is affixed to and parallel to said opposing side wall such that light emitted by the plurality of light emitting diodes is projected onto the ground surface adjacent to the truck wall.
