公路隧道用高压钠灯的试验研究

随着光源技术的不断发展，对于公路隧道中原有高压钠灯的更换，考虑到一次性更换成本及所换下的灯具如何再利用的问题，不可能一蹴而就。在现有已运营的隧道中，如何在大部分都是采用电感镇流器高压钠灯照明的情况下，用过渡型灯具逐步替换原有灯具且保证其使用功能是值得思考的问题。根据公路隧道的视觉特点，结合隧道实地用灯的对比试验，探讨对电感镇流器、反光板进行改造后，其对隧道照明亮度和能耗的影响，为隧道灯具的改进和选择提供依据。

Research on High-pressure Sodium Lamp in Highway Tunnel

With the constant development of luminous source technology,taking into account the cost of one-time replacement and the problem how to re-use the changed lamps,the replacement of the original high-pressure sodium lamp in the highway tunnel can not be achieved easily.In the existing operational tunnels,how to use transitional lamps gradually to replace the original lamps and ensure the using function is a problem worth for consideration,when most use the lighting of magnetic ballast high-pressure sodium lam...
