LIGHT-EMITTING DIODE RADIATION SOURCE FOR TRANSPORT CONTROL SYSTEMS Russian patent published in 2010 - IPC H01L33/50 H01L25/13 

FIELD: physics.

SUBSTANCE: in a light-emitting diode radiation source having at least one or more semiconductor light emitters, monochromatic radiation emitters in the UV or optical region, a light emitter holder with connection leads, a radiator and a casing lens, in accordance with the invention, the semiconductor light emitters and monochromatic radiation emitters in the UV or optical region are coated with a luminophor. The wavelength of the radiation emitters coated with luminophor lies in the 450-455 nm range, and its chromaticity coordinates lie in the range X=(0.310, 0.315, 0.360, 0.360)±0.001, Y=(0.330, 0.310, 0.370, 0.350)±0.01.

EFFECT: invention enables design of a light-emitting diode radiation source which combines all advantages of light-emitting diode devices on one hand, and its parametres weakly depend on ambient temperature on the other hand.
