道路与隧道照明的评价标准不是"亮不亮",而是照度、均匀度与眩光控制。LED 替换传统高压钠灯后,同样的功耗可以做到 1.5~2 倍的地面照度。上海曦韵照明把隧道灯与路灯的选型要点做成一页速查。
误区一:瓦数越大越好——超过标准照度后继续加亮只会增加电费与眩光;误区二:忽略维护系数——LED 寿命长但驱动与密封仍会老化,选质保 5 年以上的产品更稳妥;误区三:只看灯具价——含配电、安装与智能控制的整体方案价比单灯价更有参考价值。
Q:隧道灯功率怎么配?入口段要不要更亮?
A:隧道照明按视觉适应梯度分段:入口段最亮,向中间段逐级降低。具体功率按设计照度(入口段 cd/m² 与路面照度 lux)计算,不能全隧道一个功率到底,否则既费电又影响行车安全。
Q: How should tunnel light wattage be distributed?
A: Tunnel lighting follows an adaptation gradient: brightest at the entrance, decreasing toward the middle. Wattage is calculated from design luminance/illuminance values, not applied uniformly, to save energy while keeping traffic safe.
Q:LED路灯和高压钠灯比省多少电?
A:达到同等路面照度,LED 路灯通常比高压钠灯节能 40%%~60%%,再叠加智能调光(后半夜降功率运行),综合节电可达 60%% 以上,且显色性更好、维护周期更长。
Q: How much energy do LED street lights save versus high-pressure sodium?
A: For equal road illuminance, LED saves 40-60% versus sodium lamps; with smart dimming (reduced output after midnight), total savings can exceed 60%, plus better color rendering and longer maintenance intervals.
Q:道路灯具质保多久算靠谱?
A:行业主流为灯体 3~5 年、驱动 3 年;建议选整体质保 5 年、光衰承诺(如 30000 小时 L80)明确的品牌,并保留检测报告备查。
Q: What warranty period is considered reliable for road luminaires?
A: The industry norm is 3-5 years for the housing and 3 years for the driver. Choose brands with 5-year overall warranty and explicit lumen-maintenance commitments (e.g. L80 at 30,000 hours), and keep test reports on file.
