LED chips occupies a major part of the cost of factory high bay lights, so the main way to reduce the cost of LEDs is to reduce the cost of LED chips.

The key to the development of LED chip technology lies in substrate materials and epitaxial growth technology. The basic materials have evolved from traditional sapphire materials, silicon and silicon carbide to new materials, such as zinc oxide and gallium nitride. In just a few years, LEDs have made major breakthroughs in light efficiency and made a series of technological improvements, including chip structure, surface roughening and multiple quantum well structure design.

The cost of silicon substrates is very low, and the technology is constantly improving. However, the current luminous efficiency is still not satisfactory. If this development speed is maintained, once it reaches a higher level, silicon substrates will become the most important technical solution, and enterprises will also become an inevitable choice. Obtain huge economic returns.

Improve the light efficiency of factory LED high bay lights

Increasing light efficiency can also start from increasing the proportion of effective light. Thin-film chip technology can reduce the light output loss on each side, and more than 97% of the light is output from the front through the reflective surface at the bottom, so most of the light obtained through power conversion is effective light, which not only significantly improves the light efficiency of the LED , It also creates excellent convenience for lens design. Thin-film chip technology is the core technology for the production of ultra-bright LED chips.
