Title (EN) VEHICLE LAMP
(FR) LAMPE DE VÉHICULE
(JA) 車両用灯具
Abstract:
(EN) In order to provide a vehicle lamp that exhibits superior heat dissipation, a vehicle lamp (100) is provided with: a substrate (10); a semiconductor light source (20) which is mounted on the substrate (10); a lens (30) which emits light from the semiconductor light source (20); and a heat sink (40) having a planar first surface (40a) which is formed in the shape of a plate from a metal material, is in contact with and affixed to the substrate (10), and supports the lens (30), and a planar second surface (40b) which is the back surface of the first surface (40a), the heat sink (40) being plastically deformed by a plurality of recesses (45) disposed in a prescribed pattern in a surface machining area (44) on the second surface (40b) that includes an area on the back side of the contact area.
(FR) Afin d'obtenir une lampe de véhicule qui présente une dissipation de chaleur supérieure, l'invention propose une lampe de véhicule (100) qui comporte : un substrat (10) ; une source de lumière à semi-conducteur (20) qui est montée sur le substrat (10) ; une lentille (30) qui émet de la lumière à partir de la source de lumière à semi-conducteur (20) ; et un dissipateur thermique (40) ayant une première surface plane (40a) qui est formée sous la forme d'une plaque à partir d'un matériau métallique, est en contact avec le substrat et fixée à ce dernier (10), et soutient la lentille (30), et une seconde surface plane (40b) qui est la surface arrière de la première surface (40a), le dissipateur thermique (40) étant plastiquement déformé par une pluralité d'évidements (45) disposée selon un motif prescrit dans une zone d'usinage de surface (44) sur la seconde surface (40b) qui comprend une zone sur le côté arrière de la zone de contact.
(JA) 放熱性に優れた車両用灯具を提供するために、車両用灯具(100)は、基板(10)と、基板(10)に実装された半導体型光源(20)と、半導体型光源(20)からの光を出射するレンズ(30)と、金属材料により板状に設けられ、基板(10)が接触して固定されレンズ(30)が支持される平面状の第1面(40a)と、第1面(40a)の裏面である平面状の第2面(40b)とを有し、第2面(40b)のうち接触領域の裏側の領域を含む表面加工領域(44)に所定のパターンで配置された複数の凹部(45)により塑性変形された状態のヒートシンク(40)とを備える。
