With the continuous improvement of technology, LED manufacturers' pursuit of lighting trend has gradually changed from the high light efficiency and long life in the past to the current high light quality and healthier lighting products.
Natural light full spectrum LED lighting development trend
Comfortable and healthy illumination becomes consumption new demand, what kind of illuminant is comfortable and healthy illuminant? Humans have been living on the earth for millions of years, evolving with the changes in living environments, but the only constant is reliance on and adaptation to the sun's rays. Therefore, it can be considered that natural light or sunlight is the most comfortable and healthy light source for human beings. So when health lighting products are introduced, manufacturers almost always use sunlight as a benchmark, similar to or even better than sunlight.
The spectrum of sunlight includes ultraviolet, visible and infrared spectrum curves, which can be called full spectrum. Full spectrum LED light source of natural light refers to the proportion of each band in the visible part of LED light source is similar to that of sunlight, and the color index is close to 100. The traditional LED light source, whose luminescence mode is mainly about 450nm wavelength of blue light chip, can stimulate fluorescence powder to form white light, which will lead to excessive blue-green light radiation and lack of some blue-green light and deep red light. In particular, some low-quality light source products can easily lead to vision loss, cataract, blindness and other eye diseases of different degrees. Therefore, high quality natural light full-spectrum LED light source has become a new trend of healthy and comfortable lighting development.
