LIGHT-EMITTING DIODE EMITTING HOMOGENEOUS PARALLEL LIGHT

摘要

The invention relates to a light-emitting diode (LED) and a source of light comprising a plurality of light-emitting diodes used for homogeneously illuminating surfaces by means of parallel light beams. The aim of the invention is to create an LED and a source of light comprising a plurality of LEDs, which make it possible to illuminate surfaces in a homogeneous manner by means of parallel light beams. Said aim is achieved by an LED (1), the lens body (2) of which is provided with a Fresnel lens (3) used for reflecting light beams with a parallel beam path, and by providing said Fresnel lens (3) with total reflection surfaces (5).
