BACKLIGHT UNIT AND LLUMINATION SYSTEM USING THE SAME

摘要

PURPOSE: A backlight unit and a lighting system using the same are provided to secure uniform brightness by using a reflector for air guides having an inclined surface. CONSTITUTION: A light source module(100) is arranged between a first and a second reflector(200,300). A heat radiation member(400) is contacted with the light source module. A bottom chassis(500) supports the second reflector and the heat radiation member. The upper surface of the bottom chassis includes a flat surface and an inclined surface. The flat surface is adjacent to the light source module. The inclined surface is sloped or extended from the end of the flat surface. The lower surface of the bottom chassis is inclined on the inclined surface. [Reference numerals] (AA) Air guide
