LIGHT-EMITTING DIODE LIGHT SOURCE (VERSIONS) Russian patent published in 2015 - IPC H01L33/00 

FIELD: physics, optics.

SUBSTANCE: invention relates to electronic engineering. In a white light-emitting diode (LED), having a housing and a reflector, the housing is made of heat-scattering material, the inner part of the housing is in the form of at least one segmented reflector which forms a directional pattern of light flux distribution, having a layer of reflecting material consisting of at least one layer and a layer of light-transmitting dielectric material consisting of at least one layer. At least one LED chip is mounted inside the housing. The housing is covered on the top by a converter which is made from at least one layer of light-transmitting material. A layer of a point phosphor is deposited on at least one side of the converter. The side of the converter directed towards at least one LED chip is coated by a layer of reflecting material consisting of at least one layer.

EFFECT: providing high efficiency of a white LED light source with a remote converter, providing high colour homogeneity and enabling specification of the directional pattern of the emitted light flux with a small size of the white LED light source.
