Claims (2)
- LED光源および前記LED光源に熱的に接続された放熱部材を有する光源ユニットを収容した、アウターレンズとハウジングで形成された灯室と、
前記灯室から灯室外に延長されて再度前記灯室に至る通気路と、によって密閉構造の空気循環路が形成されてなる車両用LED灯具であって、
前記通気路に、前記空気循環路に空気を循環させるためのファンを有した空気循環手段が設けられており、
前記アウターレンズには、前記空気循環手段と気密に連通するように貫通孔が設けられ、
前記空気循環手段は、前記灯室外の下方前部に前記アウターレンズを介して取り付けられており、
前記通気路の少なくとも一部は前記ハウジングを気密に連通するように前記灯室内まで延設されたダクトであり、
前記灯室内に位置する前記ダクトに設けられた吹出口から噴出する空気が直接前記放熱部材に当てられることで、該放熱部材が冷却されて前記LED光源の点灯時の温度上昇が抑制されることを特徴とする車両用LED灯具。 - 前記灯室内に温度センサが設けられると共に前記灯室外に前記温度センサによる検知温度が設定温度以上になると前記空気循環手段を作動させる空気循環手段制御回路を有していることを特徴とする請求項1に記載の車両用LED灯具。
