According to the invention, useless power consumption can be reduced, the energy-saving effect is enhanced, and the method can bewidely applied to the field of LED control.

Description

technical field [0001] The invention relates to LED control technology, in particular to an LED street lamp control device and a control method thereof. Background technique [0002] Intelligent lighting controller (that is, LED light control device), also known as programmable lighting controller, that is, the lighting program of the controller can be modified according to the needs of the user, for example, modify the speed, time, pattern, Synchronous and asynchronous etc. Moreover, the controller has good expansibility, and can perform combined synchronous and asynchronous operation of multiple control boards according to the needs of users, so as to meet higher requirements. Usually, the controller uses a stable and reliable microprocessor chip, such as a 51 single-chip microcomputer, as the hardware control core. The microprocessor chip is equipped with a corresponding lighting program, and the host computer can communicate with the microprocessor chip. The interface ...

AI Technical Summary

Problems solved by technology

However, the existing LED street lamp control devices do not have effective and intelligent control technology, so it is easy to cause excessive useless power consumption of the LED street lamp control device, that is to say, the current LED street lamp control device is still difficult to meet the high energy saving requirements
