Side reflector for illumination using light emitting diode |
摘要 |
An LED illumination unit uses a first reflector comprising a reflecting surface formed as a surface of revolution about a first revolution axis. The LED emits light about a first LED axis towards the reflecting surface of the first reflector. The first LED axis is non-parallel to the first revolution axis and the light emitting area of the first LED unit is positioned substantially at a focus of the reflecting surface. The reflector may also have two or more reflecting surfaces for collecting and directing light from two or more respective LEDs.
