Embodiment Construction
[0032] A method for dimming lamps using adaptive pulse width modulation technology:
[0033] a. Using time-people and vehicle flow optimization control, the clock module generates a reference clock signal, which is sent to the port of the computer module, and the built-in computer determines the corresponding time according to the time-people and vehicle flow statistics of pedestrians and vehicles on urban roads. The time-illuminance adjustment rate is built into the built-in computer, and then according to the time-illuminance adjustment rate, the pulse width modulation signal is output from the adaptive pulse width modulation terminal to drive the intelligent power switch device and control the luminous intensity of the light-emitting element to achieve the actual illuminance best match for
[0034] b. Adaptive pulse width modulation technology dimming method is adopted. The photoelectric sensor outputs the corresponding voltage according to the ambient light level, and send...
