Since the birth of high-power LED lamp bead, it has been used in outdoor lighting and trade lighting, such as new year's Eve power street lamp, industrial and mining lamp, projection lamp, etc. With the aggravation of the competition in LED industry and the rapid growth of high-power LED skills, at present, the use of high-power LED devices has become more and more popular. With the indoor lighting as a new target for the growth of LED industry, high-power LED devices will also occupy a larger share in the application of indoor lighting. The reason why high power LED is more and more widely used in indoor lighting is as follows:

1. High power LED lamp beads have the advantage of organic energy: in the R & D and testing of Tongjia optoelectronics Dongguan company, relevant engineers invented that high power LED lamp beads not only have the advantage of ordinary LED lamp beads (high brightness, low light decay, longer service life), but also have the advantage of high luminous flux, higher cost performance and better luminous efficiency.

2. High power LED lamp beads have the advantage of price: Tongjia engineer explained that we have been thinking about it from the cost level of our mutual partners. When LED develops new lamps and lanterns, when it adopts traditional LED components, compared with the
