LED spotlight
First Claim
1. An LED spotlight comprising:
- a housing, an LED and a reflector within the housing, and a handle that protrudes from the housing, wherein the reflector is to collimate light from the LED into a beam, wherein the reflector has a focal length, and wherein the reflector has a diameter within a range from 3 to 12 inches to produce intense illumination of a relatively small area at a distance many times the focal length of the reflector and beyond.

Abstract
LED lamp has LEDs aimed rearwards with either a concave mirror to the rear of each LED, or one concave mirror to the rear of two or more LEDs, collecting the light from the LEDs to form a forward projecting beam. LEDs may be high power types that require heatsinking. LED lamp may have a lens forward of each LED to collimate the radiation produced by the LEDs into a beam, where at least one lens has at least one aspheric curved surface. LED lamp may have a transparent reflective optic to collimate the radiation produced by each LED into a beam. LEDs mounted to heatsink mount with spokes and ring to support LEDs in place above mirror and conduct away heat.

9. An LED spotlight comprising:
- a housing, a plurality of LEDs and a plurality of reflector elements within the housing, and a handle that protrudes from the housing, wherein each reflector element is associated with a respective LED to collimate light from the LEDs into a beam, wherein the reflector elements have a focal point, and wherein the reflector elements together produce intense illumination of a relatively small area at a distance many times the focal length of the reflector elements and beyond.

10. An LED lamp, comprising:
-
a) a head section that contains at least one light emitting diode that emits radiation, and contains at least one concave reflector, wherein the at least one light emitting diode is aimed rearwards towards the at least one concave reflector for receiving and collimating a majority of the rearwardly directed radiation into a beam, and b) a handle section such that the lamp can be hand held, wherein the head section further contains a heatsink mount to which the at least one light emitting diode is mounted, the heatsink mount comprising a plurality of spokes extending radially away from the at least one LED toward the head section to support the at least one LED in the head section in place above the reflector and to conduct heat from the at least one LED. - View Dependent Claims (11, 12, 13, 14)
