Abstract

The invention discloses a color temperature adjusting device and a color temperature adjusting method, relates to the technical field of lighting, and aims to solve the problems of poor real-time performance and low accuracy in color temperature adjustment of light-emitting devices. The color temperature adjusting device comprises a calculation unit and a control unit. The output end of the calculation unit is connected with the input end of the control unit. The calculation unit is used for acquiring the duty ratio of RGB channels of a light-emitting device at the current moment according to current ambient brightness information and current moment corresponding to the current ambient brightness information. The control unit is used for adjusting the color temperature of the light-emitting device at the current moment and in the current environment according to the duty ratio of the RGB channels of the light-emitting device at the current moment. The color temperature adjusting device is applied to the color temperature adjusting method, and is used for accurately adjusting the color temperatures of the light-emitting devices in real time.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a color temperature adjustment device and method. Background technique [0002] Color temperature is an index used to measure the spectral quality of a light source. The higher the color temperature, the cooler the light, and the lower the color temperature, the warmer the light. The colder or warmer the color temperature of the light will make people feel uncomfortable, it can be seen that the color temperature can affect Therefore, more and more light-emitting devices are equipped with color temperature adjustment devices. [0003] The existing color temperature adjustment devices mainly adopt the following methods to adjust the color temperature: the first method is to set a memory in the light emitting device, and the color temperature adjustment formula preset in the memory controls the light emitting color temperature of the light emitting device, and the light emitting d...
