LED DIMMING SYSTEM

摘要

Disclosed is an LED dimming system, comprising: an integrated driver module, and at least one LED module. Each LED module comprises at least one LED branch. An input end of the integrated driver module is connected to a power source. The integrated driver module receives a control signal indicating an adjustment instruction, and is used to output a DC bus voltage to each LED module, wherein the DC bus voltage carriers the adjustment instruction. Each LED module is used to detect the adjustment instruction carried in the DC bus voltage, and adjust the current in the LED branch in the LED module according to the adjustment instruction. The LED dimming system merely uses one integrated driver module, has a simple structure and is easy to control. Therefore, the cost of the whole system is low.
