Many border characters can be made using an advertising marking machine, also known as a border marking machine. It is a common advertising device used to make advertising borders. Sometimes, the illuminated characters made by the marking machine are installed on the door head. If the brightness of the illuminated characters is different, there are several situations: the light is not on, some strokes of the characters are not illuminated, some are well lit, some are not well lit, the colors of the illuminated characters are different, some are completely white, some are yellow, but visible to the naked eye, there are obvious differences. Some LED luminous characters that have been used for a long time have been found to have uneven light emission, which is actually not related to the edges made by the marking machine, but mainly due to internal reasons. Below, we will briefly understand the reasons for the uneven light emission of luminous characters made by the marking machine
The reason for uneven illumination of luminous characters produced by marking machines is:
1. Different models of lamps are used
The lighting effect of different models of lamps from different manufacturers varies to some extent. Generally speaking, few companies do this. They require the use of a uniform batch of lamps during production to avoid the problem of different lighting effects. Different batches from the same manufacturer may also have certain differences. Be sure to avoid this very basic mistake during production.

2. Uneven arrangement of light sources
Perhaps you brought too many LED lights along the way, but this should not be too many. Please ask the manufacturer of the lights you purchased for the specific number of lights per string. There are some places that are too bright and some places that use too little, so the brightness is definitely different. The arrangement density of the light sources should be operated according to the requirements, and cannot be arranged arbitrarily. Generally, companies have requirements when making them, and the light sources should be arranged according to the company's requirements.
3. There is leakage current
Some installation sites may have certain electrical leakage, or the wiring may not be properly routed during the writing process, or the joints may not be properly connected. Starting from the second character, there may be electrical leakage where the adhesive tape of the terminal is broken and grounded. This requires that the wiring be properly routed and checked repeatedly during production.
4. Series connection
The main line pulled out by the power supply is connected with a word first and then the second one is connected in series. As the current passes through, it becomes smaller and the brightness decreases as the current decreases
5. Insufficient transformer power
To use the normal required transformer, use different transformers according to the size of the characters.
In the face of such a situation, we analyze using two power sources (transformers). For example, if you have four words, use one for the first two and one for the last two. You can place the power source in the middle and connect it at both ends to perfectly solve this problem. It is better to use a slightly thicker main line, and then pull a line from the power source to connect the last four words, and use the main line for the first four words. Of course, the second solution is more effective and completely solves the problem. When making LED luminous characters, it is required to use a unified batch and model of light source. In terms of using wires, it is required to use wires specified by the state, with good quality and long service life. Attention should be paid to the spacing between light sources and the connection of circuits during production. Before leaving the factory, it is necessary to conduct inspection to ensure that the product is qualified before leaving the factory.
The above is the complete content of the reasons for uneven light emission in the production of luminous characters by marking machines. We hope this article can be helpful to everyone.
