Abstract

The invention provides an illumination system capable of adjusting brightness and color temperature and a control method. The illumination system comprises a cold and warm light source, a processor, a light source driver, a photosensitive element and a control module. Wherein the control module is used for acquiring a control instruction of a user; the photosensitive element is used for acquiring ambient light brightness data of the lighting system; the processor is used for determining a target driving waveform driven by the light source based on the control instruction and the ambient light brightness data; and the light source driver is used for controlling the cold-warm light source to emit light with corresponding brightness and corresponding color temperature grade based on the target driving waveform. The technical problem that the brightness and the color temperature cannot be automatically adjusted in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a lighting system and control method with adjustable brightness and color temperature on home appliances. Background technique [0002] Household kitchen appliances, such as range hoods, steamers and ovens, and other home appliances with lighting systems, need to turn on the lighting system to check the color of the food surface to judge the maturity of the food during the cooking process; It is very important for the kitchen appliances of the system; looking at the lighting systems of existing kitchen appliances, most of the lighting systems of kitchen appliances use halogen lamps as light sources; the defect of halogen lamps as light sources is that it is impossible to adjust the brightness and color temperature etc. However, the color temperature of the lighting system is an important factor that affects the user's observation of food color changes (the brightness cha...
