www.jiangtao3.com Shanghai LED production installation maintenance services company LED luminous characters features: 1, high brightness: particularly suitable for high-rise buildings advertising characters. 2, the maintenance is simple: Its easier than plastic characters, neon word maintenance. 3, energy saving: the same brightness than any one word saving more than 80 ads. LED light source word choice: LED to the state and users can save a lot of power, undertook to save a lot of man-hours parties. LED application technology development, to the highly competitive advertising industry has added new vitality. Its unique, different lighting situations, has been widely used in the production of advertising products field. Different specifications of the LED with different light emitting angles and different brightness. How, then, to the different products to choose the right LED, it can not only maximize efficiency, but also to minimize costs? Now we look at professional advice Optoelectronics Technology Co., Ltd. Shanghai Siping. LED luminous characters in the application and precautions to solid light source are the following requirements: First, LED luminous characters with different specifications and different shaped complex projects, requiring limited-shaped light source have not universal; Second, because the installation is complete, LED luminous characters maintenance is extremely inconvenient, to reduce maintenance costs, requires a light source with a long life; Third, LED luminous characters have sufficient brightness Afai advertising works produced by the above requirements for LED light modules, with more than function. Offer applies to three-dimensional luminous characters LED light source, there are two: piranhas and small straw hat. Piranha LED module suitable for gable height 8-10cm between the luminous words. In general, ￠ 3 ￠ 5 and head piranha LED angle of about 90 degrees and 120 degrees. In the distance is used in the plastic characters under piranha LED modules, light radiation can open. Not only save the number of modules, the screen luminance meter test, the utilization of light intensity is also just right. For the shorter word wall, word and shape of the plastic luminous sculpture light words, it must use light-emitting angle of 160 degrees of flat head piranha module LED modules and small straw hat. A large optical radiation area can reduce the amount of modules, while the shorter word wall but also improves the emission luminance of the font. Both organically and follow the law of conservation of energy, but also reflects the importance of correct choice of LED. It is worth noting, LED luminous characters LED light module in use process, must pay attention to voltage drop problems. Do not only do a loop, from the first series to end. This will not only due to the voltage difference between the brightness caused by inconsistent end to end, will produce single overcurrent burned circuit board problem. The correct approach is more parallel loop as much as possible, in order to ensure a reasonable distribution of voltage and current. In addition, the internal cavity for the use of the word anti-corrosion materials, preferably with a white primer to increase its reflection coefficient. Contact: Hu Lin
