1. At this stage, the light source of the light -emitting characters is mainly commonly set in the LED three lights, five lights, and six lamps with the input voltage of the DC12V. Pay attention that if you do not install the switching power supply when installing the emitting character, do not directly power the light word or the LED light source module directly into the market, otherwise the LED light source will burn the LED light source because the voltage is too high.
Second, in order to avoid the long -term load of the switching power supply, the best power supply and LED load power of the switching power supply are 1: 0.8, and the service life of the product will be more secure and long -lasting according to this.
3. If the module exceeds 25 groups, the connection should be separated first, and then connects to the light -emitting box in parallel from high -quality copper core wires greater than 1.5 square millimeters. Properly increase the line diameter. In order to avoid short circuit, the end of the module must be cut and paste. If necessary, use a self -attack screw to fix the outdoor use of the outdoor.
Fourth, there must be enough brightness. The spacing brightness of the module requires between 3 and 6cm, and the thickness of the word can be selected between 5 and 15cm. There are two LED light sources suitable for luminous characters: people and small straw hats. The luminous module of the people is suitable for luminous characters between the height of the word wall between 8-15cm?
Fifth, in the process of using LED emitting modules, be sure to pay attention to the problem of voltage drop. Don't just do only one loop, from the first string of couplet. This will not only make the brightness inconsistent due to the different voltage between the first and tails, but also cause the problem that the single -circuit current is too large to burn the circuit board. The correct approach is to connect as much as possible to ensure that the voltage and current distribution is reasonable.
6. For the inside of the word cavity, if you need to use anticorrosive materials, it is best to use a white primer to increase its reflection coefficient.
