摘要
在明视觉和中间视觉条件下,选取5个背景亮度对10名视觉正常的测试者进行反应时间测试试验,研究高压钠灯(HPS)、金属卤化物灯(MH)、紧凑型荧光灯(CFL)和发光二极管(LED)这4种光源的光效,及其光效相互之间的换算关系。同时,基于反应时间试验结果,以高压钠灯为基准,计算其余3种光源的亮度对比系数、相对光效和折算发光效率,最后综合确定不同光源在隧道照明环境中的适宜性和节能性。
Under the conditions of photopic vision and mesopic vision,this paper tests response time of 10 testees with normal vision by selecting 5 background light intensities to study lighting effects of 4 light sources including high-pressure sodium lamp（HPS）,metal halide lamp（MH）,compact fluorescent lamp（CFL） and light emitting diode（LED） and conversion relationship between them.At the same time the paper calculates brightness contrast coefficient,relative lighting effect and reduced luminous efficiency of other 3 light sources with high-pressure sodium lamp as a reference and based on test results of response time,and finally determines suitability and energy conservation of different light sources in tunnel lighting environment in a comprehensive way.
