LIGHT-EMITTING DIODE WITH HEAT-SENSITIVE LIGHT ATTENUATION ALONG BLACK BODY LINE Russian patent published in 2019 - IPC H01L33/50 F21K9/64 F21K9/65 

FIELD: lighting.

SUBSTANCE: invention relates to the field of lighting equipment and concerns a lighting device. Device has a light source and a light-converting element, which includes a light-transmitting matrix. Light-transmitting matrix is configured in thermal contact with the light source and comprises a first luminescent material and a heat-sensitive liquid crystal connection. First luminescent material is configured to convert at least part of the light source light and, optionally, the light of the second luminescent material into the light of the first luminescent material. Illumination device is designed so that to enable light of the lighting device including light of the light source, light of the first luminescent material and, optionally, light of the second luminescent material. Light-converting element is made with possibility of changing by means of electric power supplied to light source one or more of color and light color temperature of lighting device.

EFFECT: technical result consists in simplification of design and possibility of automatic change of spectrum of emitted light along line of black body at change of illumination device luminosity.
