FIELD: physics.
SUBSTANCE: described light-emitting diode (LED) contains a crystal (crystals), a conical reflector and luminophor, wherein the crystal emits in the violet spectral range, the luminophor is base on barium-strontium orthosilicate, the reflector has an optimum angle of inclination of walls and height, a polymer layer with the luminophor is deposited on the reflector, as well as on the light-emitting surface of the LED.
EFFECT: highly efficient green LED, with luminous efficacy which is higher than that of traditional green LEDs, is obtained based on the disclosed invention.
