水底灯与地埋灯同属"嵌装"灯具,一个入水、一个入地,选型时最容易犯的错是只看 IP 等级。上海曦韵照明结合喷泉、泳池、广场与步道项目经验,把两类灯具的选型体系整理如下。
滨水与广场项目中,水底灯打亮水体与喷泉,地埋灯照亮铺装边界与人行流线,两者色温统一(3000K/4000K)可形成连续的光环境。DMX512 版本可编排整体联动节目,把静态夜景变成可运营的夜游产品。
Q:喷泉水底灯用 IP67 还是 IP68?
A:长期浸没在水下的灯必须选 IP68;IP67 只防短时浸水,喷泉泵启停带来的水位波动与气泡冲击会加速密封老化。音乐喷泉还要额外关注灯体抗水流冲击结构。
Q: For fountain lights, is IP67 enough or is IP68 required?
A: Lights permanently submerged require IP68. IP67 only tolerates temporary immersion; pump cycling and bubble impact accelerate seal aging. Musical fountains also need impact-resistant housings.
Q:广场地埋灯选多少瓦合适?会被车压坏吗?
A:行人区域 6~12W 足够;需要明显光斑或洗亮墙根可用 18~36W。车道与停车场必须选重型抗压地埋灯(钢化玻璃面盖 + 铸铝/铸铁灯体),并核对抗压等级指标,普通地埋灯不可上车。
Q: What wattage suits plaza in-ground lights, and will vehicles crush them?
A: 6-12W is enough for pedestrian areas; visible pools of light or wall washing may use 18-36W. Vehicle areas require heavy-duty rated fixtures with tempered glass and cast iron/aluminum housings — standard in-ground lights are not traffic-rated.
Q:水底灯和地埋灯可以通用配电吗?
A:可以共用 12V/24V 恒压系统与防水电源,但水边安装须把电源与接线盒置于水位线以上并做好防水;一个电源回路不宜混接过多灯,避免同时故障造成大面积灭灯。
Q: Can underwater and in-ground lights share the same power supply?
A: They can share 12V/24V constant-voltage systems and waterproof power supplies, but near water all power units and junction boxes must sit above the waterline with proper sealing. Avoid too many lights per circuit to prevent mass failures.
