| 摘要 |
本发明提供一种包含以下各项的照明设备：(1)一个或多个发光二极管晶片(Light-Emitting Diode，简称LED)设置在一个或多个LED晶片基板上。(2)一个或多个镜头基板，每个镜头基板安装上一个或多个镜头组，每一镜头组有一层或多层镀膜，用以把从LED晶片发出的光，穿越镜头组后，光的色温将会改变。(3)一个传动系统，用以改变LED晶片基板和在同一光轴上的镜头基板的相对位置，从而改变LED晶片发出光的光锥角，以能够高强度远程照明。在一个实施案例中，镜头基板可以在平行于镜头组光轴的方向移动，或在一个与晶片基板平行的平面上移动。; (2) one or more lens bases each of which comprises one or more lenses, said lens comprises coatings for changing color temperature of the light produced by said LED chips and transmitted through said lens; and (3) a motion transmission system to change the position of said lens bases relative to said LED chip bases, wherein each of said lenses is placed along the light path of one or more LED chips, and said lens changes the light beam cone angle of light emitted from said LED chips to produce long distance high intensity illumination. In one embodiment, the lens bases can be moved in a direction parallel to the optical axes of said lens, or moved on a plane that is parallel to said LED chip bases. |
