Abstract

The invention relates to an automatic adjusting color temperature illumination system based on a visual perception of human eyes. The system comprises: a mode selection circuit, a digital power supply circuit, a microcontroller, a temperature sensor, a humidity sensor, a brightness sensor, a timer circuit, an artificial scene geography information selection and color temperature brightness setting circuit, a light source driving circuit and an RGB three primary color light source. The temperature sensor, the brightness sensor and the timer circuit are all connected with the microcontroller. External environment signals are sent to the microcontroller. The microcontroller controls the light source driving circuit through processing the signals so as to control the color temperature and light and darkness of the RGB three primary color light source. The invention has the following advantage: combining influences of the light source color temperature on human physiology and mentality to control the color temperature and the brightness of the light source so that human comfort can be satisfied maximally by the light source and indoor illumination can become more humanized.

Description

technical field [0001] The invention relates to an illumination system for adjusting color temperature by adjusting RGB three primary color light sources, in particular to an illumination system for automatically adjusting color temperature based on human visual experience. Background technique [0002] The color of the light source is often expressed by the concept of color temperature. When the color of light emitted by a light source is the same as that radiated by a black body at a certain temperature, the temperature of the black body is called the color temperature of the light source. In blackbody radiation, the color of light varies with the temperature, and the blackbody presents a gradual change process from red-orange-red-yellow-yellow-white-white-blue-white. [0003] Human beings live on the earth, and the color temperature of sunlight is constantly changing from morning to night. Human vision has adapted to this change after years of interaction with sunlight. ...
