技術說明

本發明係關於一種光源品質量測裝置，係包括一光接收單元、一第一處理單元、一記憶單元、一第二處理單元、 一顯示單元、以及一電源管理單元。本發明之裝置係以人的生理感受度為基準所進行的指標評估;於評估的技術上則係藉由光度函數將一光源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，進而決定該光源之光源品質之高低;如此，相較於習用的演色性指數評估方法，本發明之光源品質量測裝置所採用的光源品質評估方式係更具公正性與一致性。 The present invention relates to a light source quality evaluating device, comprising ：a light receiving unit, first processing unit, a memory unit, a second processing unit, a display unit, and a power management unit. The device is used for evaluating 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 throuth a luminosity function. Next, the method compares the luminance spectrum of the light source with a black body radiation spectrum thereof. Therefore, an index of special resemblance with respect to the black body radiation (SRBR) would be calculated and then obtained, such that SRBR can be used for evaluating the quality of the light source. Moreover, comparing to conventional color redering index (CRI), SRBR is a better light source quality evaluating method because of having faimess and consistency.
