ABSTRACT:
An electric lighting device that uses a concave reflector to collect and concentrate the light emitted by a plurality of luminescent light sources. The cooperating relationship between the orientation of the light sources and contour of the reflector increases the parallelism of the light beams projected from the device so that they can combine to form a composite beam. The spatial relationship between the light sources and the inclusion of a light transmitting medium reduce overheating and increase the efficiency of the device.
