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.

Claims

1. A lens comprising:

a plurality of protrusions;

each protrusion having varying thickness;

wherein the outermost edges of said protrusion have the thickest measurement;

wherein the center of said protrusion has the thinnest measurement; and

wherein said plurality of protrusions is adapted to merge individual beams of light into a single beam of light.

2. The lens of claim 1, wherein the protrusions are semi-circular.

3. The lens of claim 1, wherein at abutting borders of said protrusions are flattened.

4. A lens comprising:

a plurality of semicircular monolithic protrusions having a roughly circular border mounted in a single lens piece;

each monolithic protrusion comprising a plano-convex lens;

said plurality of semicircular protrusions extending along at least two axes in a substantially flat plane of the lens piece;

wherein said plurality of semicircular monolithic protrusions is adapted to merge individual beams of light into a single beam of light.

5. The lens of claim 4, wherein abutting borders of said protrusions are flattened.

6. A light system comprising:

a housing means supporting a plurality of light emitting diodes;

a lens means attached to said housing means over said plurality of light emitting diodes; and

said lens means comprising a series of semicircular monolithic protrusions having a roughly circular border mounted in a single lens piece;

said plurality of semicircular monolithic protrusions extending along at least two axes in a substantially flat plane;

wherein said plurality of monolithic protrusions is adapted to merge individual beams of light into a combined single beam of light.

7. The light system of claim 6, wherein each monolithic protrusion has a varying thickness;

wherein the outermost edges of said monolithic protrusion have the thickest measurement; and

wherein the center of said monolithic protrusion has the thinnest measurement.

8. The light system of claim 6, wherein each monolithic protrusion comprises a plano-convex lens.

9. The light system of claim 8, wherein each plano-convex lens comprises a flat side and a curved side;

and

wherein light travels from said flat side to said curved side.

10. The light system of claim 6, wherein each of said plurality of light emitting diodes is approximately centered next to a monolithic protrusion.

11. The light system of claim 6, wherein abutting borders of said monolithic protrusions are flattened.
