FIELD: physics.
SUBSTANCE: high colour rendition index white LED has a heat-conducting base, a lead frame, a holder mounted on the top surface of said heat-conducting base, LED chips mounted on said heat-conducting base and in said holder, and transparent silicone covering the top surfaces of said LED chips, in which said holder is a conical cup having an open bottom and protrusions for mixing light on the inner surface of the wall of the holder and in which said lead frame has a size which corresponds to the bottom of said holder and is mounted on the outer side of said holder and on the top surface of said heat-conducting base, and in which said LED chips contain at least six types of LED chips which emit light with different wavelength peaks, wherein each type of LED chips includes at least one chip, and said LED chips are configured and connected electrically on said heat-conducting base such that the interval between wavelength peaks of two adjacent LED chips is equal to 20-35 nm, said LED chips further contain electrodes which are electrically connected to leads of said lead frame.
EFFECT: high colour rendition index and luminous efficacy.
