DIRECT VIEW LIGHT BASED ON LIGHT EMITTING DIODES (LEDS) WITH HOMOGENEOUS MIXING OF OUTPUT LIGHT Russian patent published in 2017 - IPC F21S10/02 

FIELD: lighting.

SUBSTANCE: light includes a plurality of light sources (132), made in combination and configured to generate a plurality of different colours of light, one first light-mixing chamber (110) and at least one second light-mixing chamber (120), in optical communication with the first mixing chamber by means of at least one opening (134). At least one output surface (112) of direct view light is connected to the first light-mixing chamber. The light sources are contained in the second light-mixing chambers, which are designed to prevent direct incidence of light, emitted from the light sources onto the output surface (surfaces) of the light. The first light mixing chamber and the output surface (surfaces) of the light are configured to mix light, emitted from the light sources so that all the light, leaving the surface (surfaces) of the light substantially has uniform brightness and colour.

EFFECT: production of mixed light in the direct view light, which is essentially uniform in brightness and colour.
