It is a new trend for light boxes to use solar energy as the light source of LED injection molding modules. Solar energy is a green and environmentally friendly renewable resource, which is in line with the national emission reduction policy and is the trend of the times. It is believed that the application of solar technology will provide a bright prospect for the development of the advertising light box industry .

In recent years, China's light box industry has developed rapidly, and its production capacity has expanded rapidly, and many manufacturers have entered the industry one after another. In this context, and at the same time considering labor costs, some old-fashioned light box manufacturers in Europe, America and even South Korea have successively reduced or stopped production, providing favorable conditions for Chinese light box companies to occupy the international market share. However, since most of the production enterprises in this industry are mainly private and self-employed, the industry supervision and self-discipline system and orderly competition order have not yet been formed. China's light box industry is currently in the process of transforming from disorder to orderly development.

China is a big energy-consuming country. At present, China's power supply is tight. Therefore, the development of light box technology must first change the light source. Use low-energy and environmentally friendly light sources. The use of LED injection molding modules on light boxes is imperative. LED injection molding modules are environmentally friendly, because LED injection molding modules are economical and affordable, and a reform of advertising light boxes will surely arise. We believe that the most energy-saving and environmentally friendly light boxes will represent the mainstream of future development. If solar power is used on the LED injection molding module, it will no longer rely on the traditional power supply system and call itself a system. Power saving, free cable, wire construction, reduce man-made damage to the ring. And solar energy is absolutely safe, will not cause leakage, electric shock accidents, greatly reduce business risks and safety hazards.
