Automatic control system and method for lamp power-onTechnical Field
The application relates to the technical field of illumination, in particular to a lamp power-on automatic control system and method for detecting the circuit conductivity of a lamp.
Background
In an LED control system, the LED control system generally comprises a power supply, a controller, and a lamp. In some simple LED control systems, the addition of a controller increases the cost and reduces the stability of the lamp. In the production test process of the traditional lamp, a light controller is required to be connected to verify that the serial signal lines among the lamps are complete. Therefore, the production test steps are increased, and the production efficiency is reduced.
The invention provides an automatic control system for lamp power-on, which can omit a light controller so as to save cost and improve stability. And the defective products in the lamp can be detected in the state of being electrified only.
