LED light-emitting character  is an advertising logo product that is illuminating by LED lamp. It is loved by many advertisers and popularized rapidly due to its varied colors, even and bright luminous effect, high efficiency, energy saving and convenient installation and use. According to the different kinds of LED luminous effect, the LED light-emitting products are divided into: LED exposed lights, luminous words, LED plastic light-emitting words, LED light box luminous characters, LED back emitting words, LED resin luminous characters and many other varieties. Many Chinese industrial chain, low concentration, high-end products R & D capability is low, the advertising industry industry manufacturing technology level low phenomenon still exists, the next few years will be the advertising industry high speed shock period, a direct consequence of this is to bring high-speed shocks lead to the expansion of the trend of brand camp polarization. It is expected that in the next few years, there are absolutely not so many companies that can live on the market in the next few years. But the high speed shock of the advertising industry will bring great opportunities, and the result of the shock will make the market more rational. The domestic road of high-end electric is "bumpy". In 12th Five-Year, the government will continue to intensify the localization of high-end equipment and parts in advertising industry. Some famous companies, such as a diversified company, including advertising planning, design, production, lighting, decoration, prop, and fixed point procurement. Semiconductor ultra high brightness light-emitting diode (LED), especially the nitride light emitting diode, has the advantages of small size, low voltage, long life, fast response advantages, no flicker, less energy consumption, less heat, it has gradually become a new generation of green, energy saving, environmental protection, long-life lighting light source.
