White LED is usually formed using two methods. The first method is to use "blue light technology" to combine with fluorescent powder to form white light; The second method is a variety of monochromatic light mixing methods. Both methods have been able to successfully generate white light devices. Hella, a German company, has developed aircraft reading lights using white LED technology; A street in Canberra, the capital of Australia, has been illuminated with white LED street lights; China's urban traffic management lights are also replacing early traffic order indicators with white LED. It is foreseeable that in the near future, white LED will definitely enter homes to replace existing lighting
