Talking about the current form of urban lighting products
At present, the most common building body lighting products are mainly digital tubes, because they are cheap and effective. This is the main reason why they are widely used. However, due to the mixed quality of digital tubes, plus some lighting companies The construction level is too low, which leads to the unsatisfactory effect after installation, and some minor problems often occur, such as the unsynchronized scrolling of the digital tube light bar, often flickering or not bright, which is very annoying for customers, but The solution to these problems is very simple.
The non-synchronization of the light bar of the digital tube when scrolling is mainly caused by the signal controller. The digital tube has three wires, namely the positive electrode, the negative electrode, and the signal wire. If the signal wire is not pressed to the correct position of the controller, then After the power is turned on, the scrolling on both sides will be out of sync. If the lights of some of the digital tubes dim after the entire row of digital tubes are powered on, it can be concluded that there is a problem with the power supply, indicating that the output current or voltage is insufficient and the brightness is dimmed. Just replace the power supply with a good one.
