摘要
在车辆行驶过程中,隧道照明会对视觉造成光源频闪现象。《公路隧道通风照明设计规范》JTJ026.1-1999第4.2.2条款和第4.3.4条款对闪烁频率有重要规定,如果隧道内灯具间距布置不当,所产生的"频闪效应",就会造成视觉错误甚至危及行车安全。本文阐述了闪烁频率的基本概念,详细解析《规范》对闪烁频率的区间定义,分析隧道照明灯具布置中存在的设计误区,通过计算与验算给出合理的灯具布置间距,作为安全、经济的隧道照明设计参考。
in the process of vehicle, the tunnel lighting for visual light stroboscopic phenomenon. Specification for design of highway tunnel ventilation lighting the first clause 4.2.2 JTJ026. 1 - 1999 and the first clause 4. 3.4 is important to flicker frequency regulation, if the tunnel span arrangement of lamps and lanterns is undeserved, produced by the ＂stroboscopic effect＂, can cause visual error and even endanger the safety. This paper expounds the basic concept of flicker frequency, parsing the ＂specification＂ of the flicker frequency range definition, analysis of existing in the tunnel lighting lamps and lanterns decorate design error, through the calculation and checking, the lamps and lanterns of a reasonable distance for safe and economic of tunnel lighting design reference.
