Abstract
An apparatus and method for producing an improved light emitting diode (LED) spotlight. One or more layers of LEDs shine light into an array of elliptical reflectors. Each elliptical reflector has an LED at one focal point and shares the second focal point with a larger parabolic reflector that collimates the light. A hole in the center of the parabolic reflector receives additional LEDs, with or without collimation optics.
Claims20
A light assembly comprising:
- a housing having a longitudinal axis;
- a first layer of light emitting diodes (LEDs) located at a first position on the longitudinal axis within the housing;
- and
- a second layer of LEDs located at a second position on the longitudinal axis within the housing,
- wherein each of the layers comprises a plurality of optical reflectors.
