LED has high luminous efficiency, energy saving, long service life, long-term maintenance-free, no mercury, no pollution, environmental protection, wide color temperature range, easy to create dynamic space lighting effects, and can meet different lighting needs at the same time. In today's information In the era of advanced technology and new technology, electronic display devices play a very important role, such as the government's policy advocacy, corporate image and product advertisements, live performances on the stage, and various information instructions in public places, etc., all need to be passed through various electronic display devices. In order to achieve the best effect, LED can be widely promoted, so the requirements for LED are also increased. In the prior art, the drive control chip used to control the lamp generally needs four control signal lines, so it is connected with a flexible wire. Generally, there are two input heads, two output heads, one power connector and one signal connector. Due to the large number of connectors, the failure rate of the connectors is high, the reliability is low, and it is easy to cause problems such as short circuits and dropped connections. The four signals interfere with each other, affecting normal use and shortening the service life of the lamp. the
