LIGHT-EMITTING DEVICE AND METHOD OF LIGHT EMISSION Russian patent published in 2013 - IPC F21V7/00 

FIELD: electricity.

SUBSTANCE: invention relates to a light-emitting device (10, 50, 70), comprising the first source (12a, 52a, 72a) of light, the second source (12b, 52b, 72b) of light, a partially transparent mirror (16, 56, 76) and a collimating facility (14a, 14b, 54a, 54b, 74), made as capable of at least partial collimation of light of the first and second sources of light, so that during operation substantially the entire at least partially collimated light of the first and second sources of light drops onto the partially transparent mirror. The partially transparent mirror is arranged as capable of receiving during operation substantially the entire light at least partially collimated and emitted by the first and second sources of light, and reflecting a part of light emitted by the first source of light, and passing a part of light emitted by the second source of light, and vice versa, so that the light from the first source of light is fully imposed onto light from the second source of light after reflection/passage in the partially transparent mirror. The collimating facility comprises parts arranged in a mirror order that accordingly correspond to the first source of light and the second source of light. The first source of light and the second source of light are arranged at opposite external ends of the collimating facility.

EFFECT: device improvement.
