| 摘 要： | 为了研究中间视觉下常用光源的透雾性,运用光谱仪测量不同雾浓度下钨丝灯、LED灯、金卤灯和高压钠灯的光谱,进行透过率比较.研究表明:在明视觉下,钨丝灯的透雾性最佳,LED的透雾性最差；雾浓时金卤灯的透雾性优于高压钠灯,雾稀时高压钠灯的透雾性优于金卤灯,四种光源透过率在不同中间视觉亮度下的变化均不超过5％.该研究结果对道路照明灯具的设计与检测具有重要参考价值.

| Abstract: | This paper focuses on studying the fog penetrability of common light sources in mesopic vision. The spectra of tungsten filament lamp, LED, Metal Halide Lamp （MH）, High Pressure Sodium Lamp （HPS） in different fog densities are measured with a spectrometer, and their fog penetrabilities are compared. It is found that in photopic vision, the fog penetrability of tungsten filament lamp is the best while that of LED is the worst. When the fog is thick, the fog penetrability of MH is better than that of HPS. When the fog is weak, the fog penetrability of HPS is better than that of MH. For all of the four lights, the variation of the fog penetrability with various mesopic vision brightness is less than 5%. This research results are very important reference for designing and testing the road lighting. |
