Abstract
LED based searchlight/sky light including, in a basic embodiment, a housing; an LED array supported in/by the housing, a heat sink in communication with the LED array, and a reflector supported in the housing such that the LED array is supported by the housing a distance sufficient above the reflector to allow the light emitted by the LED array to be reflected by the reflector. The reflector is preferably a parabolic reflector such that the light emitted by the LED array is reflected by the parabolic reflector in an intense collimated beam. The LED array may be supported above the parabolic reflector a distance equal to the focal length of the parabolic reflector. A power supply may also be included to regulate the electrical current applied to the LED array.
