1, The LED three light module with a conventional input voltage of DC12V is mainly used as the power supply.
It needs to output DC12V through a constant voltage switch power supply. Therefore, it is important to note that when installing the luminous character, if a switch power supply is not installed, do not directly connect the luminous character or LED light source module to the AC 220V power supply, otherwise the LED light source may be burned out due to high voltage.
2, To avoid long-term full load operation of the switching power supply, the optimal power ratio for the switching power supply and LED load is 1:0.8. According to this configuration, the product's service life will be safer and more durable.
3, If the module exceeds 25 groups, it 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 luminous box. The length of the power cord should be as short as possible. If it exceeds 3 meters, the wire diameter must be appropriately increased. The unused connections at the end of the module must be cut and pasted firmly to avoid short circuits. If necessary, self tapping screws should be used to fix the non waterproof series. When used outdoors, waterproof measures must be taken for the groove type characters;
4, It needs to have sufficient brightness.
The visual brightness of the module spacing needs to be between 3 and 6CM, and the thickness of the characters can be selected between 5 and 15CM. There are two types of LED light sources suitable for luminous characters: piranhas and small grass hats. The piranha luminous module is suitable for luminous characters with a wall height between 8-15cm.
5, When using LED luminous modules, it is important to pay attention to the issue of voltage drop.
Never make just one circuit, connecting from the beginning to the end. This approach not only causes inconsistent brightness between the head and tail due to voltage differences, but also leads to the problem of burning out the circuit board due to excessive single current. The correct approach is to connect as many circuits in parallel as possible to ensure a reasonable distribution of voltage and current.
