LIGHT-EMITTING DEVICE Russian patent published in 2018 - IPC F21V8/00 

FIELD: optics.

SUBSTANCE: invention relates to lighting engineering. Light-emitting device (1) comprises a plurality of first solid state light sources (21, 22, 23, 24, 25, 211) adapted for, in operation, emitting first light (13) with a first spectral distribution, and first light guide (3) comprising first light input surface (31), first end surface (32) extending at an angle different from zero with respect to each other and at least one first further surface (33, 34, 35, 36) extending parallel to first light input surface (31), wherein plurality of first solid state light sources (21, 22, 23, 24, 25, 211) is arranged at first light input surface (31). First light guide (3) is adapted for receiving first light (13) with the first spectral distribution at first light input surface (31), and guiding at least a part of first light (13) with the first spectral distribution to first end surface (32). Light emitting device further comprises at least one first optical element (91), which is adapted for shaping light that is output from first light guide (3) through at least a part of at least one first further surface (33, 34, 35, 36) so as to provide first shaped light (81), and at least one second optical element (92) arranged at or on first end surface (32).

EFFECT: technical result is a wider range of equipment.
