LAMP DEVICE FOR VEHICLE

To provide a lamp device for vehicles, which secures sufficient heating efficiency for an outer lens, enhances the functions of defrosting and snow melting of the outer lens, and achieves simplification and weight reduction of the structure.SOLUTION: A lamp device A for vehicles used for a headlight, a winker, or the like of an automobile, has: a light emitting element 1; a reflector 2 that reflects the light of the light emitting element 1 in a front direction; an outer lens 3 disposed in front of the reflector 2; a heat conductor 5 on a back side of the reflector 2, which thermally connects the light emitting element 1 and an outer peripheral portion of the outer lens 3; a partition plate 6 that covers a back side of the heat conductor 5; a first heat insulating layer 7 between the reflector 2 and the heat conductor 5; and a second heat insulating layer 8 between the heat conductor 5 and the partition plate 6. Sufficient heating efficiency for the outer lens 3 is ensured, the functions of defrosting and snow melting of the outer lens 3 are enhanced, and simplification and weight reduction of the structure are achieved.SELECTED DRAWING: Figure 1 【課題】アウタレンズに対する充分な加熱効率を確保して、アウタレンズの曇り除去や融雪の機能を高めると共に、構造の簡略化及び軽量化を実現する車両用灯具を提供する。【解決手段】自動車のヘッドライトやウインカーなどに用いられる車両用灯具Ａであって、発光素子１と、発光素子１の光を正面方向に反射するリフレクタ２と、リフレクタ２の正面に配置したアウタレンズ３と、リフレクタ２の背面側に、発光素子１とアウタレンズ３の外周部とを熱的に接続する熱伝導体５と、熱伝導体５の背面側を覆う仕切り板６と、リフレクタ２と熱伝導体５との間で、第１断熱層７を有すると共に、熱伝導体５と仕切り板６との間に、第２断熱層８と、を有する。アウタレンズ３に対する充分な加熱効率を確保して、アウタレンズ３の曇り除去や融雪の機能を高めると共に、構造の簡略化や軽量化を実現する。【選択図】図１
