Why does the demand for LED back light spreading light boxes increase? Since 2013.

1. The market for LED back light spreading light boxes is large. First of all, because of the development and maturity of LED technology, the core components of the backlight have been solved. The traditional large light box uses lamp tubes or EEFL. Both traditional lamps have several disadvantages: first, they consume a lot of power, second, they are easily damaged during transportation, third, the installation is extremely troublesome, and fourth, the service life is short, and the lamps need to be replaced every year. The mature technology of LED has completely solved the above problems.
2. The trend of turning the side light source to the backlight source: The so-called side light source is the side lighting, and the light guide plate is used to guide the light to form a surface light. However, there are many restrictions on side light emission. 1. The maximum size is 160*310CM. (There are also manufacturers on the market that can achieve 1.6*6M, but this is very unreasonable in terms of technology and materials, and it is not a qualified product) 2. The side light source cannot reach high brightness Claim. For example: 150*300CM light box, light guide plate and LED light all use the best materials. The illuminance of the light box is hard to exceed 3000LX. And the backlight light box. That is, the light is lit behind, and the entire light box is covered with LED light bars. Brightness is very easy to reach 6000LUX

Such as airport light boxes, subway light boxes, parking lot light boxes, mobile phone light boxes in various mobile phone shops across the country, urban pedestrian tunnel light boxes, railway station light boxes
