我们描述了由白色发光二极管（LED）以及太阳能电池和蓄电池系统组成的电力节能型路灯的照明特性和系统。该原型路灯由两个 LED 光源构成，每个光源总共包含 700 个 10 cd 级白光 LED。白光LED照明系统主要分为控制部分、电源部分和LED照明部分三个部分。照度通常为80 lx。当有人靠近灯附近 2 m 范围内时，人体传感器就会捕捉到这一情况。然后照度增加到约 660 lx，比白色白炽灯亮约 50 倍。显色指数估计为85，与三色荧光灯管的显色指数相似。照度分布可以通过我们最近开发的“LED 光源多源”理论进行分析。
We describe the lighting characteristics and systems of the power energy-saving type street lamp which consists of white light-emitting diodes (LEDs), and a solar-cell and battery system. The prototype street lamp has been constructed by two LED light sources, each of which includes a total of 700 units of 10 cd-class white LEDs. The white LED lighting system is mainly divided into three components which are the control, the electric-power supply and LED lighting divisions. The illuminance is normally 80 lx. When a person approaches within 2 m near the lamp, the body sensor catches the situation. The illuminance then increases to about 660 lx, which is about 50 times brighter than that of a white incandescent lamp. The color rendering index is estimated to be 85 which is similar to that of three color fluorescent tube. The illuminance distribution can be analyzed by our recently developed 'multi sources of LED light' theory.
