摘要(Abstract):

因LED光源发光面积小、亮度高等特点,使得在后组合灯中广泛使用,却带来了驾驶员在等红绿灯或慢速跟车时制动灯对驾驶员造成直接眩光的问题,这会带来行车安全隐患。本文基于统一眩光值UGR理论,采用de Boer量表来评价人眼直视灯具的眩光程度,验证URG模型合理性及制动灯在特定环境下对不同年龄段驾驶员的眩光程度。结果表明:UGR理论模型在一定程度上能够评估制动灯对人眼不舒适的眩光程度,眩光指数越小,眩光时间相对就越长。31~50岁年龄段对光刺激不敏感,同等条件下眩光程度弱,眩光时间短。夜间在城镇道路行驶中,两车相距3 m时,灯具光强大于150 cd或表观亮度高于2×105cd/m5cd/m2,制动灯对后方驾驶员会造成不舒适眩光,存在安全隐患。
Due to the characteristics of small luminous area and high brightness of LED light source, it is widely used in the rear combination light. However, it brings the problem of direct glare caused by the stop lamp when the driver is waiting for the traffic light or following the car slowly, which will bring the hidden danger of driving safety. In this paper, based on the UGR theory of unified glare value, De Boer scale was used to evaluate the glare degree of human direct vision lamps, and the rationality of the URG model and the glare degree of brake lamps to drivers of different ages in a specific environment were verified. The results showed that: to a certain extent, the UGR theoretical model can evaluate the glare degree of the brake lamp on the discomfort of human eyes. The smaller the glare index, the glare time is the longer. The age group of 31~50 years old is not sensitive to light stimulation, and under the same conditions, the degree of glare is weak and the glare time is short. When the distance between two vehicles is 3 m, the light intensity of the lamp is stronger than 150 cd or the apparent brightness is higher than 2×102,制动灯对后方驾驶员会造成不舒适眩光,存在安全隐患。

When the distance between two vehicles is 3 m, the light intensity of the lamp is stronger than 150 cd or the apparent brightness is higher than 2×105cd/m5cd/m2 when driving on urban roads at night, the brake light will cause uncomfortable glare to the rear driver, and there are safety risks.
