New Solar Spectral Fitting Technique Based on LED
This paper studies a new type of solar spectral fitting technique based on LED.Firstly,Using the light collecting equipment collected several typical periods of the solar spectrum of Beijing.And then,After a preliminary analysis,five specific bands LEDs are used to fit the target solar spectrum.Among them,the use of two pieces of normal white light LEDs,a single LED with 480nm wavelength,a single LED with 500nm wavelength,and a single LED coated red fluorescent powder emitting 650nm light.To sum up,through the five different bands LEDs fitting the solar spectrum of Beijing,light is more soft,eye viewing is more comfortable; Compared with the acquisition of the solar spectrum,fitting degree reached 98%,total power 3.5-3.8w,light efficiency is about 100lm / w,color rendering index(CRI) is about 85.
