AI summary

A lighting system based on gesture recognition mechanism includes a first proximity sensor, a second proximity sensor, a processing module and a lighting module. The first proximity sensor generates a first sensing signal. The second proximity sensor generates a second sensing signal. The processing module receives the first sensing signal and the second sensing signal. The processing module generates a gesture recognition result according to the order of receiving the first sensing signal and the second sensing signal. Then, the processing module generates a light adjusting signal according to the gesture recognition result, such that the light adjusting signal is transmitted to the lighting module so as to adjust the light characteristic of the lighting module.
