Abstract
The invention relates to the field of lighting technology and addresses the issues of poor light efficiency and stability in existing full spectrum white light LED implementations, which provides a full spectrum semiconductor lighting device and health lighting fixture, which includes: blue light LED chips and fluorescent powders. The blue light LED chips comprise at least a first and second blue light chip, each with peak wavelengths within a specific wavelength range, differing from each other. The fluorescent powders include first, second, third, and fourth fluorescent powders, each with peak wavelengths in distinct wavelength ranges. Through the synergistic use of chips and fluorescent powders, the invention enables the resulting full spectrum lighting devices to have higher light efficiency and stability.
