INTENSIFIER, DISPLAY AND TV RECEIVER Russian patent published in 2011 - IPC F21S2/00 G02F1/00 H04N7/00 

FIELD: physics.

SUBSTANCE: intensifier 12 comprises assemblage of linear light sources 17 arranged in parallel, and light reflector 40 arranged on side of linear light sources that corresponds to opposite side of light emitting sides. Linear light sources 17 are arranged to provide for small gap area 17A wherein gap between them is relatively small and large gap 17B wherein their spacing is relatively great. Light reflector 40 comprises open recess 50 arranged under linear light sources 17. Said open recess 50 is made so that aperture factor of said recess in entire light reflector 17A of small gap exceeds that in large gap area 17B.

EFFECT: simple design, smooth distribution of illumination brightness.
