Beijing roof characters make | 13121820298 professional production of roof characters, Beijing roof characters make | a professional production of roof characters, buy the regular manufacturers of qualified LED single light particle (the need for manufacturers to provide quality parameter description), to produce their own modules. It was not to seek cheaper to buy in the electronic market LED single light particle or ready-made modules. To purchase the module, the module is installed should see a few resistors, install a resistor module is best not to use. Resistance in the module is played by limiting the role, it is easy to heat. Long continuous use, once resistance to burn, this module is not bright. LED lights are generally not bad. Do not throw away the modules, simply replace an equal value resistors can be used normally. This saves costs for the production units. In order to reduce trouble, save money, the best choice of modules installed two resistors. In addition, the production module supplier's production facilities to understand, to see whether to use the module in the production of anti-static facilities. If no additional anti-static facilities, in use even if the resistance is not burned, LED lights can easily be breakdown. 2, LED lamp is generally safe to use current 20 mA, more than this value, although the brightness will increase the number, but the color will be significantly accelerated decay. Therefore, when buying already assembled LED modules must test its output current. Less than 20 mA brightness is not enough, more than 22 mA of LED life, so that the color decay faster. 3 white LED lights in the factory to go through the spectral separation (not after separation by the LED light emit some white, some bluish, some yellow), by the separation device is expensive, General small plants are not the kind of equipment, so the production of white light are generally carried out by separation of manufacturers get, because it is not their own plant products, spectral separation would not be so careful. Some small plants can not be bothered by separation. They are generally at a low price to pull customers. Therefore, the purchase of white LED Do not blindly freeloaders, be sure to purchase the same manufacturer, same batch, LED light tube single light particles or modules of the same color to make the same batch of luminous words.
