Spectral Analysis of Natural Solar Ultraviolet B for Improving Vitamin D Synthesis

日光中的紫外線B為人體合成維生素D的最主要貢獻。本文提出了一種用於長期測量太陽紫外線B的光譜分析系統與分析方法。該系統具有抗候、低成本和高分辨率的優點，透過測量與分析固定位置的太陽光的絕對輻照度信息，並在考慮維生素D的作用合成函數與皮膚癌發生的權重函數後，即能提出出門曬太陽的最佳時期。在這段時間內，人類可以獲得最高的維生素D合成，而對皮膚的損害最小。這項研究為健康燈具的開發，建立了一個重要的參考方案。 The paper presents a spectral analysis system for the long-term solar ultraviolet B measurement. It has the advantages of weatherproof, low cost and high resolution. The absolute irradiance information of sunlight in a fi xed location has been measured and analysed. After considering the weighting function of vitamin D action synthesis and skin cancer generation, the best period to go out for sunning could be proposed. During this period, humans can get the highest vitamin D synthesis with minimum damage of skin. This study provides a solution for database establishment of healthy lamp development.
