摘要
利用光栅光谱仪对几款具有护眼功能的手机开展实验,测得在不同模式下手机背光源的光谱,检验手机护眼模式的有效程度.此外利用光谱仪测量LED灯与一款已经停产的实验用太阳能灯的光谱图,评测用LED灯做为其替代光源的可行性.
The grating spectrometer was used to test the effectiveness of the eye-protection mode of several mobile phones by measuring the spectrum.The backlight spectra of different modes were measured and then the effectiveness of the eye-protection modes was tested.In addition,the spectrometer was used to measure the spectral images of LED lights and a kind of experimental solar lights that have been stopped production.The result helped to evaluate the feasibility of using LED lights as its alternative light source.
