LIGHTING DEVICE Russian patent published in 2018 - IPC G02B19/00 

FIELD: lighting.

SUBSTANCE: invention relates to lighting devices. Device (1) comprises plurality of light sources (2) and the first secondary optic (3) and the second secondary optics. First secondary optics is made so that the light emitted from the light sources was directed directly to the first secondary optics. First secondary optics emits light in the second secondary optics direction, and the secondary optics is the retro-reflective collimating element (4) having peripheral surface (43) arranged to extend around the plurality of light sources and the first secondary optics. Emitted by each light source from plurality of light sources light is mutually overlapped before its output from the lighting device and the first secondary optic (3), comprising the reflecting surface one or more segments (5) to reflect light back into the said first secondary optics and the light-emitting surface one or more segments (6) intended for the light output from said first secondary optics.

EFFECT: invention provides reduction in size, increase in the collimation degree.
