LIGHT EMITTING MODULE Russian patent published in 2018 - IPC F21K99/00 

FIELD: lighting.

SUBSTANCE: invention relates to a light-emitting module, which comprises a light mixing chamber and at least one light-emitting diode. Result is achieved in that the light-emitting module comprises mixing chamber (10) arranged to mix light, wherein mixing chamber (10) comprises base (12) having a highly reflective inner surface, circumferential side wall (14) having a highly reflective inner surface and semi-reflective light exit window (16); and at least one light emitting diode (5) arranged on the inner surface of circumferential side wall (14) such that light emitted from at least one light emitting diode (5) is emitted into mixing chamber (10) for mixing the emitted light within mixing chamber (10), wherein semi-reflective light exit window (16) is arranged to output light emitted from at least one light emitting diode (5) and mixed within mixing chamber (10), wherein the aspect ratio of width (W) and height (H) of mixing chamber (10) is in the range of 1 to 8, wherein the reflectivity of semi-reflective light exit window (16) is in the range from 30 % to 80 % for light emitted from light emitting diode (5).

EFFECT: technical result is provision of light-emitting modules capable of providing uniform illumination.
