Abstract RU 2468286 C2

FIELD: electricity.

SUBSTANCE: lighting device 12 includes light source 17, housing 14 containing light source 17 and hole 14b for passing of light emitted by light source 17 and optical element 15a provided so that to be directed to light source 17 and close hole 14b. Optical element 15a is formed of element with uniform light-reflection and it has the first surface 30a directed to light source 17 and the second surface 30b opposite to the first surface 30a. Light-reflective section 31 is formed on section of the second surface 30b which is overlapped with light source 17. Light-reflective section 31 reflects light from the first surface 30a. Light-diffusing section 32 is formed on section of optical element 15a which is not overlapped with light source 17. Light-diffusing section 32 diffuses light.

EFFECT: providing lighting device in which light emitted is used effectively for provision of uniform brightness and energy conservation, also providing display device containing such lighting device and TV set containing such display device.
