Abstract
【解決手段】 照明装置の一方の端部である前部に位置する発光ダイオード8と、発光ダイオードよりも後方の側部に位置し、側部から光を透過させる側方透過部3と、発光ダイオードの後方に位置し、発光ダイオードから出る光の方向を変えて、側方透過部に向けてその光を出射させる光路変更部15,15aとを備える。
【選択図】 図3
Description
(a)放物面の焦点付近に配置されたフィラメントから発せられた光は四方に広がり、直接前方に出射される光以外は、放物面で反射されて前方への平行光線を形成する。この平行光線を、直接前方に出射される光と合わせて前方レンズにより所望の配光パターンにする(例えば特許文献1、2参照)。
(b)フィラメントから発せられた光は、マルチサーフェスミラーにより所望の配光パターンにされて前方に投射される。前方レンズは単にカバーの役割をする。このマルチサーフェスミラーは、各部分がフィラメントから入射された光を所定の方向に反射し、各部分の集合によって所望の配光パターンが得られるように、各部分の大きさおよび角度配置が決められている(特許文献1、2参照)。
