Abstract

　上下の縁部に配置された光源モジュール１，１と、この光源モジュール１，１の間に配置された導光板２と、光源モジュール１及び導光板２の背面側に配置された背面板３と、この背面板３の背面側に配置されたファン取付板４と、このファン取付板４に取り付けられた冷却ファン５を備える。背面板３に、光源モジュール１，１の背面側の部分に突出部３ａを形成し、上下の突出部３ａの間の部分に平坦面３ｂを形成する。ファン取付板の前側面４ａと背面板の平坦面３ｂとの間に、冷却風路１１を形成する。光源モジュールのＬＥＤチップ１ａの熱を背面板の突出部３ａに集中させて、この熱を冷却ファン５から冷却風路１１に導いた風で外部に放出する。
