Abstract

The invention relates to power engineering and to lighting technology and can be used in designing, manufacturing and operating various illumination devices. The aim of the invention is to provide for high energy efficiency in an illumination device. The technical results are the following: increasing the efficiency of a device by approximately two times; decreasing heat flow into a room (or device) in which a light source is located; decreasing thermal loads on a light fixture; extending the service life of the light fixture; avoiding the use of mercury. All of the technical results are achieved by means of a light source containing an energy source, a housing, and a diffuser, and in that a substance is applied at least to the diffuser, said substance being capable of converting energy absorbed by the diffuser (said energy being emitted by the energy source) into light radiation, said light source differing from the prototype in that a laser is used as the energy source.
