The reasons for the luminous characters themselves. The problems of LED luminous characters themselves mainly come from the production and assembly process. 

Everyone knows that the lamp is fragile. Now the luminous characters are equipped with LED lamps, which are much better than before. However, in the process of producing LED luminous characters, they must be handled with care. Avoid collisions and bumps. 

In addition, the waterproof performance of LED luminous characters and other problems that may arise during assembly. When producing LED light boards, due to the fierce competition in the LED industry, some companies use the quality of the source materials themselves in order to save costs. The service life of LEDs cannot be achieved at all. Therefore, to make a good LED luminous character logo, every detail and step of production must be checked. 

External reasons. Generally, LED luminous characters are installed outdoors, so the outdoor installation angle and installation details are particularly important. Otherwise, its light decay rate will be very fast. And regular maintenance must be carried out during use. 

Maintenance also includes whether the mounting frame is fixed, whether the power is turned off during the day, and whether it has been turned off during thunder. These are the reasons that affect the life of LED luminous characters. In fact, the external reasons are to use LED luminous characters according to the standards stated by the LED luminous character manufacturers. 

 In short, the most important factor affecting the service life of LED luminous characters is the LED itself. For example, the copper foil thickness and insulation effect of the PCB board, the quality of LED lamp beads, whether the wires are welded firmly, the quality of the character shell, the sealing effect of the resin and other factors will have a certain impact on the service life of LED luminous characters.
