Abstract
(EN)

PROBLEM TO BE SOLVED: To eliminate weak points of a conventional technique; to enhance a value and attractiveness of a front lighting system of an automobile; and to provide an LED headlight using multiple LED light sources simulating point light sources.

SOLUTION: A hollow cylinder part 20 arranged symmetrically around a longitudinal axial line 18 is projected from a housing 12 having, in its inside, a base part 14 having a circumferential wall 16 arranged around the longitudinal axial line 18. A light guide 21 is positioned in the hollow cylinder part 20. The light guide 21 includes: a single exit end 22 arranged along the longitudinal axial line 18; and a plurality of arms 23 radially extended and each having an entrance end 24.

【課題】 従来技術の欠点を無くすこと及び自動車の前方照明装置の価値や魅力を高めること及び点光源を疑似する多数のLED光源を用いるLEDランプを提供することである。
【解決手段】 長手方向軸線18を中心として配列した周囲方向壁16を有するベース部14を内側に有するハウジング12から長手方向軸線18を中心として対称に配列した中空胴部20が突出される。中空胴部20内には光ガイド21が位置決めされる。光ガイド21は長手方向軸線18に沿って配列された単一の出口端22と、半径方向に伸延し且つ各々入口端24を有する複数のアーム23を有する。
