Abstract

This invention relates to an adaptive complementary green illumination system, which collects solar rays for illumination controlled by a controller, when the sunshine exceeds a requirement of illumination, it will store the exceeded part to a storage cell via a solar energy battery, when it is lower than the that, the storage cell will drive a LED irradiance tube to makeup illumination, if the cell does not store enough electricity, then the commercial power will drive the LED. The base of a collecting mirror is connected with a tracer, and the solar rays received by the collecting mirror enter into a light splitter, one part of the output of the splitter enters into an astigmatic device via fibers, the other is sent to the solar energy cell, the output of which is connected with the cell, the LED driver and the LED illumination lamp orderly by the controller, the output of the commercial converter is connected with the LED driver and the LED illumination lamp orderly and the photosensitive tube on the tracer and that of the illumination in the test room are connected with the input of the controller and the control ends of the tracer, the splitter and the LED driver are connected with the output of the controller separately.

Description

technical field [0001] The invention relates to a self-adaptive complementary green lighting system, in particular to the comprehensive utilization of the three lighting technologies, which mainly use solar energy for lighting, direct lighting by collecting sunlight, LED lighting driven by solar battery energy, and LED lighting driven by mains power. Realize automatic complementary lighting system. Background technique [0002] At present, the use of solar lighting technology mainly includes two categories: one is to use solar cells to drive LED lighting, and the way of energy conversion is "light-electricity-light". The efficiency is only about 10% to 20%. The second type is direct collection of sunlight lighting, which includes sunlight collection devices and optical fiber transmission devices, which can track the sun and transmit visible light. The disadvantage is that when the sun is strong, the light energy is not stored. When the sunlight is weak, the illumination lig...
