The voltage of the LED varies from 2-9v, and the power also has a wide range. The specific choice of LED depends on the technical requirements of the module as a product. For example, this LED module needs to output 10lm of light. In terms of appearance, it is better to use two LEDs, so you can choose a 5lm LED. Combining color (LED voltage is related to color), temperature, quality and other factors, you can find a suitable LED product.

Instructions for use of LED light source module

1. At this stage, the light source with luminous characters is mainly based on the conventional setting. The input voltage is DC12V. The LED three-lamp, five-lamp, and six-lamp light source modules are more common. They need DC12V output through a constant voltage switching power supply.

It is the power source, so please pay attention to if you do not install the switching power supply when installing the luminous characters, do not directly connect the luminous characters or the LED light source module to the mains AC 220V, otherwise the LED light source module will be burned out due to the high voltage.

2. In order to avoid long-term full-load operation of the switching power supply, the power of the switching power supply and the LED load is preferably 1:0.8. According to this configuration, the service life of the product will be more secure and lasting.

3. If there are more than 25 groups of modules, they should be connected separately, and then connected in parallel with high-quality copper core wires larger than 1.5 square millimeters to the outside of the light box. The length of the power cord should be as short as possible, if it exceeds 3 meters, it must be Properly increase the wire diameter, and the unused wires at the end of the module must be cut and pasted firmly to avoid short circuits. If necessary, use self-tapping screws to fix the non-waterproof series. When outdoor use, the groove type must be waterproof;

Fourth, there must be sufficient brightness. The visible brightness of the LED light source module spacing needs to be between 3 and 6 cm, and the thickness of the characters can be between 5 and 15 cm. There are two types of LED light sources suitable for luminous characters: piranha and small straw hat. Piranha luminous module is suitable for luminous characters with the height of the character wall between 8-15cm.

5. In the process of using luminous LED light source modules, we must pay attention to the problem of voltage drop. Don't just make one loop, connect the end in series from the beginning. Doing so will not only cause inconsistent brightness between the end and the end due to the different voltages, but also cause the problem of burning the circuit board due to excessive single-channel current. The correct approach is to connect as many loops in parallel as possible to ensure a reasonable distribution of voltage and current.
