Abstract
(EN)
A vehicle lamp fitting (1) is provided with: a lamp fitting main body (2) including a light source unit (10), and a housing main body (11) supporting the light source unit (10); and a ventilation unit (3) which is provided adjacent to the lamp fitting main body (2) and through which wind (W) from the outside passes. The light source unit (10) includes: a light source element unit (20) which emits light (L); and a heat dissipating member (30) which dissipates heat generated by the light source element unit (20). The light source element unit (20) is provided inside the housing main body (11), and the heat dissipating member (30) is provided in such a way as to be exposed inside the ventilation unit (3).
(FR)
La présente invention concerne une pièce de fixation de lampe de véhicule (1) qui comprend : un corps principal de pièce de fixation de lampe (2) comprenant une unité de source de lumière (10), et un corps principal de boîtier (11) supportant l'unité de source de lumière (10) ; et une unité de ventilation (3) qui est disposée adjacente au corps principal de pièce de fixation de lampe (2) et à travers laquelle passe le vent (W) provenant de l'extérieur. L'unité de source de lumière (10) comprend : une unité d'élément de source de lumière (20) qui émet de la lumière (L) ; et un élément de dissipation de chaleur (30) qui dissipe la chaleur produite par l'unité d'élément de source de lumière (20). L'unité d'élément de source de lumière (20) est disposée à l'intérieur du corps principal de boîtier (11) et l'élément de dissipation de chaleur (30) est disposé de telle manière à être exposé à l'intérieur de l'unité de ventilation (3).
(JA)
車両用灯具(1)は、光源部(10)と光源部(10)を支持する筐体本体(11)とを有する灯具本体(2)と、灯具本体(2)に隣接して設けられ、外部からの風(W)を通す通風部(3)と、を備える。光源部(10)は、光(L)を出射する光源素子部(20)と、光源素子部(20)で生じる熱を放熱する放熱部材(30)とを有する。光源素子部(20)は、筐体本体(11)の内部に設けられ、放熱部材(30)は、通風部(3)の内部に露出するように設けられる。
