隨著固態照明普及，人造光源潛在的光輻射危害越來越受到重視。現有光生 物安全規範針對各式光生物安全危害源，定義了不同評估計量與方法。例如：紅 外線對眼睛之傷害，是以分光輻射照度做為此項光生物危害評估之依據。然而， 光源在紅外線（2500~3000) nm之分光輻射照度，因訊號弱，不易直接量取，造 成此波段光生物危害評估之困難。本文針對（2500~3000) nm ,嘗試以環境濕度 與膠原蛋白試片做為光生物安全評估之依據，結果初步證實利用膠原蛋白作為光 生物安全評估試片之可能性。未來可進一步實驗，以此輔助或取代分光輻射照度， 實現準確評估光生物安全之目標。

As modern lighting technology becomes more and more advanced, artificial light sources, such as solid state lighting, become brighter and more popular in our daily life. However, such high luminance lighting also comes with potential photobiological hazards. Quantities and methods are defined and described in photobiological safety standards, to evaluate photobiological hazards. For example, infrared radiation hazard for the eye is evaluated based on the irradiance within the assigned wavelength range, calculated based on the measured values of spectral irradiance. However, for most of the light sources, infrared radiation between (2500~3000) nm is very low and thus difficult to be measured. As a result, it is challenging to evaluate photobiological hazards within this wavelength range accurately. Althernative methods are developed to try to solve this problem. The goal is to be able to evaluate photobiological hazards in the range of (2500 ~ 3000) nm accurately.
