结论
厂房照明选LED高棚灯（工矿灯），核心看层高、照度需求、IP防护等级。国标GB50034规定：机械加工车间照度≥300lx，电子装配≥500lx，仓储物流≥100lx。
一、不同层高的功率选择
- 层高4-6米：选100-150W LED高棚灯，间距4-5米
- 层高6-9米：选150-200W LED高棚灯，间距5-6米
- 层高9-12米：选200-300W LED高棚灯，间距6-8米
- 层高12米以上：选300-500W LED高棚灯，需配反光罩
数据依据：GB50034-2013工业建筑照度标准值
二、关键参数
1. 照度标准
- 机械加工：300lx
- 精密装配：500lx
- 一般仓储：100lx
- 包装分拣：300lx
2. 防护等级
- 一般车间：IP54（防尘防溅）
- 潮湿环境：IP65（防喷水）
- 粉尘环境：IP65+密封散热设计
- 食品车间：IP67+食品级材质
3. 色温选择
- 生产车间：5000-5700K（冷白光，提升专注度）
- 仓储区域：4000K（自然白光，兼顾舒适）
- 质检区域：5700-6500K + Ra≥90
三、节能对比数据
传统金卤灯400W vs LED高棚灯200W：
- 功率节省50%
- 照度提升约20%
- 寿命从8000小时延长至50000小时
- 维护成本降低80%
四、安装间距计算方法
以6米层高、150W LED高棚灯为例：
灯具间距 = 层高 × 1.5 = 9米（理论最大值）
但实际建议间距为层高×1.0-1.2（6-7.2米），确保照度均匀度U0≥0.6。

FAQ
Q：厂房改造LED灯多久回本？
A：按电费0.8元/度，200W替换400W金卤灯，每天10小时，年省电费约584元/盏，一般1.5-2年回本。
Q：高棚灯需要配反光罩吗？
A：层高超过8米建议配60°或90°反光罩，提升地面照度利用率15-30%。
Q：LED高棚灯寿命真的有5万小时吗？
A：正规品牌采用Lumileds/Samsung灯珠，L70寿命≥50000小时，即每天10小时可用13年。
Conclusion
Factory lighting uses LED high-bay lights — key factors are ceiling height, illuminance requirements, and IP rating. GB50034: machining ≥300lx, electronic assembly ≥500lx, warehousing ≥100lx.
1. Wattage by Ceiling Height
- 4-6m: 100-150W LED high-bay, 4-5m spacing
- 6-9m: 150-200W LED high-bay, 5-6m spacing
- 9-12m: 200-300W LED high-bay, 6-8m spacing
- Above 12m: 300-500W LED high-bay with reflector

2. Key Parameters
Illuminance Standards
- Machining: 300lx
- Precision assembly: 500lx
- General storage: 100lx
- Packaging/sorting: 300lx
Protection Rating
- General workshop: IP54 (dust/splash)
- Humid environment: IP65 (water jet)
- Dusty environment: IP65 + sealed cooling
- Food workshop: IP67 + food-grade materials
Color Temperature
- Production: 5000-5700K (cool white, enhances focus)
- Storage: 4000K (natural white, balanced comfort)
- QC area: 5700-6500K + Ra≥90
3. Energy Savings Comparison
Traditional 400W metal halide vs 200W LED high-bay:
- 50% power savings
- ~20% higher illuminance
- Lifespan: 8,000h → 50,000h
- Maintenance cost reduced 80%
4. Spacing Calculation
Example: 6m height, 150W LED high-bay:
Spacing = Height × 1.5 = 9m (theoretical maximum)
Practical recommendation: Height × 1.0-1.2 (6-7.2m), ensuring uniformity U0≥0.6.
