Abstract
The utility model relates to a multistage dimming lamp which comprises a power switch, light emitting diode (LED) luminous bodies, and a constant current power supply connected with the power switch and the LED luminous bodies in a circuit mode. A single chip is further arranged between the constant current power supply and the LED luminous bodies. Corresponding switch signals are generated by switching times of the power switch, and the switch signals are transmitted to the single chip. Current values passing through the LED luminous bodies are adjusted through corresponding pulse width modulation signals generated by the single chip according to the switch signals to switch to different dimming gears. According to the multistage dimming lamp, switching and dimming functions of the lamp are achieved through one switch, multistage dimming of the lamp is controlled by means of the switch signals, and cost of circuit installation is reduced.
