Conventional Troubleshooting Methods For Led Point Light Sources

1. Phenomenon, cause, solution, all lights are not on, the positive and negative poles of the power cord of the lights are short-circuited or connected reversely or not powered on, check the positive and negative poles of the hot wire and the main power, all the lights only turn on white lights No signal received

2. Check if the controller is working properly

3.Check whether the data and signal terminals connected to the controller are in good contact, and whether they are connected reversely

4. Is there a program corresponding to the lamp IC in the SD card? Only part of the lamp changes color, and the rear part does not change color.

5. Signal magnetic wire, short circuit ,① Check whether the clock line and data line of these two lights are connected one by one; whether they are loose and bad. ② Replace the previous light,③ The input and output terminals are connected reversely.

6. Each wire of the connecting wire should be separately wrapped with waterproof tape; the Power Supply voltage of the local lamp is dark when the light is bright and white, and the power supply voltage of the local lamp is insufficient. Pull a power cord from the power supply to the lamp when the local lamp is in white light or other light colors When flashing, the ground wire GND is poorly connected or not connected properly

① Check if the ground wire of the flashing light is connected to the ground wire of the previous light,

② Connect the negative poles of multiple power supplies in series
