Problems solved by technology

[0003] However, in urban lighting projects, the system composed of multiple LEDs or LED light groups generally has a relatively long distance, while the transmission distance of current wireless signals (such as Bluetooth or 2.4G wireless, WIFI, etc.) is very short, probably only is about 100 meters
Therefore, for lighting projects with relatively long distances, the use of wireless control has its limitations, and the scope of application is narrow.
[0004] In addition, there are still aspects to be improved in the driving of LEDs, such as the problems of high power consumption of the circuit and low accuracy of current control

Abstract

The present invention provides a multi-light source control system. By setting a main control loop, an auxiliary control loop, and a communication mode among the main control module, the main control loop, and the auxiliary control loop, various display effects of LED lamp groups are realized. Further, by improving the circuit of the LED node, it is possible to reduce the power consumption of the LED and control its current accuracy.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a multi-light source control system. Background technique [0002] With the promotion of the concept of low-carbon energy saving, LED lights have been widely used in the field of lighting. In the urban lighting project, LED guardrail tubes, LED decorative lights and LED buried lights along the street need to use multiple LED lights or multiple LED light groups to form a system that can reflect and coordinate with each other in order to have a very good visual effect. Therefore, it is necessary to independently control each LED or each LED light group through a system to control its working status at any time, including on and off status, brightness and displayed color. [0003] However, in urban lighting projects, the system composed of multiple LEDs or LED light groups generally has a relatively long distance, while the transmission distance of current wireless signals (such as Bluetooth or...
