技術說明

本發明係關於一種以黑體輻射光譜相似性分析光源品質之方法，係具有5個主要的步驟流程。本發明之方法主要係以人的生理感受度為基準所進行的指標評估。並且，於評估的技術操作上，係藉由光度函數將一發光元件的能量光譜轉換成人眼感受度較為敏感的一亮度光譜；接著再藉由與黑體輻射光譜的光譜比對，進而決定該發光元件所發出的光的品質高低；如此，相較於習用的演色性指數評估方法，本發明之以黑體輻射光譜相似性分析光源品質之方法更具公正性與一致性。 The present invention relates to a light source quality evaluating method by using spectral resemblance with respect to the blackbody radiation, which mainly comprises 5 method steps. This method is used for evaluate the quality of light based on physiological perception of human. In evaluating operation, the method firstly transfers a power spectrum of a light source to a luminance spectrum through a luminosity function. Next, the method compares the luminance spectrum of the light source with a black body radiation spectrum thereof. Therefore, a spectral resemblance with respect to the black body radiation (SRBR) would be calculated and then obtained, such that the SRBR can be used for evaluating the quality of the light source. Moreover, comparing to conventional color rendering index (CRI), SRBR is a better light source quality evaluating method because of having fairness and consistency.
