The development of led application technology has added new vitality to the highly competitive advertising industry and has been widely used in the production of advertising products. Different size of led light source also have different illumination angles and brightness. So, how to choose the right led light source for illuminated letters, so that it can maximize the efficiency and minimize the cost ? The application and use of led light source in illuminated letters mainly have the following requirements:

1. Because there are many types of illuminated letters, there are different specifications, so it is required that the light source should be versatile and not subject to the shape of the illuminated letters;

2. Due to the installation of the completed led illuminated letters maintenance is extremely inconvenient, in order to reduce the maintenance cost, the light source is required to have a longer life;

3. In the process of led illuminated letters using led light source, we must pay attention to the problem of voltage drop. Don't just make one loop from the first to the end. This will cause the brightness to be inconsistent between the first and last tails due to the different voltages, and the problem that the single circuit current is too large to burn the circuit board. The correct approach is to connect as many circuits as possible to ensure proper voltage and current distribution. In addition, if you need to use anti-corrosion materials inside the word cavity, it is best to use a white primer to increase it’s reflection coefficient.

In short, in addition to considering the stability of the led light source, it is also necessary to determine the illumination angle of the led light source according to the requirements of the product. Only reasonable selection of led with different specifications can ensure that the product quality meets the standard while minimizing the cost.
