Compact LED light module
First Claim
1. A modular LED light unit for mounting to an object to illuminate objects distally located from said light unit, said light unit comprising:
- a circuit board supporting a plurality of LED lights, said circuit board being planar and having a back side and a front side and including a plurality of apertures with said LED lights being reverse mounted to said back side of said circuit board such that each said LED light is located by and extends into a separate one of said apertures with said apertures being sized to axially align each said LED light with a corresponding said aperture into which said LED light extends such that said LED lights are positioned in axial alignment with said apertures; and
a light permeable front cover having an outer surface and an inner surface, said front cover including at least one optical structure, said at least one optical structure being located on one of said outer surface and said inner surface of said front cover, and wherein no part of said front cover extends into any of said apertures;
wherein said circuit board and said front cover are assembled together to be in engagement such that said apertures are axially aligned with said at least one optical structure whereby light emitted from said LED lights is directed into said at least one optical structure.

Abstract
A modular LED light unit for mounting to an object to illuminate distally located objects comprises a circuit board supporting a plurality of LED lights and a light permeable front cover. The circuit board includes a plurality of apertures with the LED lights being reverse mounted to the circuit board such that each LED light is located by and extends into a separate one of the apertures. The front cover includes an outer surface and an inner surface and at least one optical structure located on the outer surface or inner surface. At least one of the LED lights is axially aligned with the optical structure whereby light emitted from the aligned LED lights is directed into the optical structure.
