ABSTRACT:
A method for dimming multiple lamps includes: getting a brightness range of a lighting area which has at least two light sources, getting a dimming range of the light sources, setting the brightness of the lighting area, determining the dimming value of each light source, and defining different dimming values of at least two light sources. The luminosity adjustment upper limit and lower limit of the individual light sources are obtained. After the brightness of the lighting area is set the dimming value of each light source is determined to form the brightness of the lighting area through the two light sources of different brightness.
