投影式图像显示装置
摘要：
本发明提供比以往更能提高对发光管的球状部的冷却效果的投影式图像显示装置。本发明的投影式图像显示装置，具备：成为光源的灯具(4)；冷却该灯具的冷却扇；以及以灯具(4)为光源生成彩色图像光的光学装置，灯具(4)具备成为光源的发光管(42)和将从该发光管(42)出射的光向所述光学装置反射的反射器(41)。在反射器(41)上，在接近所述发光管(42)的球状部(43)的位置朝向该球状部(43)的垂直方向的顶部(43a)开设将从冷却扇排出的空气导入反射器(41)内的空气导入孔(44)，空气被吹到该顶部(43a)。
摘要（英）：

A liquid crystal rear projector device of the present invention includes a lamp unit providing a light source, a cooling fan for cooling the lamp unit, and an optical system for generating color imagelight with the lamp unit providing a light source, the lamp unit including a light emitting tube providing a light source, and a reflector for reflecting light emitted from the light emitting tube toward the optical system. The reflector has an air introduction hole for introducing air discharged from the cooling fan into the reflector, which is provided near the spherical portion of the light emitting tube, and faces to a vertical top of the spherical portion to blow the air to the top.
