Abstract
The present invention provides a changeable lighting device, which is connected to an alternate-current power source and which uses the switching operation of a power switch to change the light and brightness of light, comprising a compound light source that is comprised LED light sources of R, G, B colors, a direct-current power supply circuit, a power switch signal detection circuit, and an RGB control circuit. The RGB control circuit receives an output signal from the power switch signal detection circuit to control the luminance and variation of brightness of the R, G, B color LED light sources. Combining the different luminance and variations of brightness of the R, G, B color LED light sources allows the compound light source of the changeable lighting device to provide plural types display modules that have light sources of different colors and luminance.
