The editor has collected some LED injection molding module installation skills, and shared them with you here for communication and learning.
1. At this stage, the light sources used for luminous characters are mainly LED injection molding modules with a conventional input voltage of DC12V. The three-lamp, two-lamp, and one-lamp light source modules are relatively common. The DC12V output by a constant-voltage switching power supply is If there is no switching power supply installed when installing the LED injection molding module, do not directly connect the LED injection molding module to the mains AC 220V, otherwise the LED light source will be burned out due to excessive voltage.
2. In order to avoid the long-term full-load operation of the switching power supply, the optimal load power of the switching power supply and the LED injection molding module is 1:0.8. According to this configuration, the service life of the product will be more secure and durable.
3. If there are more than 25 groups of LED injection molding modules, they should be connected separately first, and then connected in parallel with high-quality copper core wires larger than 1.5 square millimeters to the outside of the LED injection molding module light box. The length of the power cord should be as short as possible. The wire diameter must be appropriately increased to 3 meters. The unused connection at the end of the LED injection molding module must be cut and pasted firmly to prevent short circuit. If necessary, use self-tapping screws to fix the waterproof series. When the series is used outdoors, waterproof measures must be taken for the groove characters;
Fourth, there must be enough brightness. The visible brightness of the LED injection molding module spacing needs to be between 3 and 6CM, and the thickness of the characters can be between 5 and 15CM. There are two types of LED injection molding module light sources suitable for luminous characters: piranhas and straw hats. Piranha luminous LED injection molding module is suitable for luminous characters with a height of 8-15cm on the word wall.
5. In the process of using LED injection molding module, we must pay attention to the problem of voltage drop. Don't just make a loop, connect it from the beginning to the end. Doing so will not only make the brightness inconsistent between the head and tail due to different voltages, but also cause the problem that the single-channel current is too large to burn the circuit board. The correct way is to connect as many circuits in parallel as possible to ensure a reasonable distribution of voltage and current.
6. If the interior of the word needs to use anti-corrosion materials, it is best to use a white primer to increase its reflection coefficient.
