LIGHTING DEVICE, DISPLAY DEVICE AND TV SET Russian patent published in 2012 - IPC F21S2/00 

FIELD: electricity.

SUBSTANCE: module 12 of rear light includes light-emitting diodes 15, light-conducting plates 18, reflective sheets 24, light-emitting-diode boards 17 and reflective parts 47. Each light-conducting plate 18 has light entry surface 34 and light exit surface 36. Light entry surface 34 is directed to corresponding light-emitting diode 16 through gap C, light from light-emitting diode 16 passes to light entry surface 34. Light exit surface 36 is arranged parallel to direction in which light-emitting diode 16 and light entry surface 34 are located. Each reflective sheet 24 is located on surface of light-conducting plate 18 opposite to light exit surface 36 and is designed to reflect light on light exit surface 36. Each light-emitting-diode board 17 is directed to corresponding reflective sheet 24. Light-emitting diodes 16 and light-conducting plates 18 are installed on corresponding light-emitting-diode boards 17. Each reflective part 47 is located on corresponding light-emitting-diode board 17, at least in area between light-emitting diode 16 and light entry surface 34, and is designed to reflect light to light entry surface 34.

EFFECT: image intensification.
