Abstract

Disclosed is a light source, which includes a light-permeable casing, a thermoconductor, which is mounted inside the casing and has a flat end portion, a plurality of radiation fins fastened to the periphery of the thermoconductor inside the casing, a light source formed of an array of LEDs and installed in the flat end portion of the thermoconductor inside the casing, and a power unit mounted inside the casing to provide the light source with the necessary working voltage. <IMAGE>
