Problems solved by technology

[0002] Daily lighting sources require good brightness, especially the consistency of chromaticity and color rendering rate. In the current semiconductor lighting technology, the generation of white light is based on the approximate white light generated by exciting yellow phosphor powder from blue light-emitting chips, but Usually, there is a lack of red light components in the white LED light source module, so tha

Abstract

The invention provides a photochromic controllable illumination device by using automatic white balance for regulation and control, and an illumination method thereof. The illumination device comprises an LED lamp-house module, a radiator and a reflecting shade. The illumination method comprises the following steps: after the light source is connected with electricity, light rays which are shined on an astigmatic sheet by LED light source and reflected back from the reflecting shade, are received and transformed to an analog signal by a photoelectric sensor which is arranged in the LED light source, then adaptation and digital-to-analogue conversion ( A/D conversion) by an A/D conversion circuit are carried out, the comparison with a targeted value in a value comparison circuit and a data processing circuit is carried out and a light regulating instruction is output, finally, the red light output response curve of the light source is regulated by a red light control circuit, and the processes are repeated till the error between the measured value and the targeted value is within the allowed range.

Description

technical field [0001] The invention relates to an optical electronic device, in particular to an illuminating device with controllable color temperature and color rendering rate, and also relates to an illumination processing method of the illuminating device. Background technique [0002] Daily lighting sources require good brightness, especially the consistency of chromaticity and color rendering rate. In the current semiconductor lighting technology, the generation of white light is based on the approximate white light generated by exciting yellow phosphor powder from blue light-emitting chips, but Usually, there is a lack of red light components in the white LED light source module, so that the color rendering of the semiconductor light source cannot reach above 0.9. The speed is not synchronized with the attenuation speed of other phosphors, so that the color rendering and consistency of semiconductor lighting cannot be greatly improved, and the lighting source cannot ...
