一、层高与功率对照
- 层高4-6米：100-150W LED高棚灯，间距4-5米
- 层高6-9米：150-200W LED高棚灯，间距5-6米
- 层高9-12米：200-300W LED高棚灯，间距6-8米
- 层高12米以上：300-500W LED高棚灯，需配反光罩
二、照度标准（GB50034-2013）
- 机械加工车间：≥300lx
- 精密装配车间：≥500lx
- 一般仓储：≥100lx
- 包装分拣区：≥300lx
三、防护等级选择
- 一般车间：IP54（防尘防溅）
- 潮湿环境：IP65（防喷水）
- 食品车间：IP67（可冲洗）
- 粉尘环境：IP65+密封散热
四、散热方案对比
- 压铸铝外壳+铝基板：成本低，散热一般，适合≤150W
- 拉伸铝+热管：散热好，适合150-300W
- 压铸铝+风扇主动散热：散热最佳，但风扇有寿命风险
建议选择被动散热（无风扇）方案，维护成本更低。
五、安装方式
- 吊链安装：最常见，适用于大多数厂房
- 吊杆安装：更稳固，适合有震动的环境
- 吸顶安装：适合低层高仓库
- 支架安装：适合墙壁或立柱

1. Height vs Wattage Guide
- 4-6m height: 100-150W LED high-bay, 4-5m spacing
- 6-9m height: 150-200W LED high-bay, 5-6m spacing
- 9-12m height: 200-300W LED high-bay, 6-8m spacing
- Above 12m: 300-500W LED high-bay with reflector
2. Illuminance Standards (GB50034-2013)
- Machining workshop: ≥300lx
- Precision assembly: ≥500lx
- General storage: ≥100lx
- Packaging/sorting: ≥300lx
3. Protection Rating Selection
- General workshop: IP54 (dust/splash proof)
- Humid environment: IP65 (water jet proof)
- Food workshop: IP67 (washable)
- Dusty environment: IP65 + sealed heat dissipation
4. Heat Dissipation Comparison
- Die-cast aluminum + aluminum substrate: Low cost, average cooling, ≤150W
- Extruded aluminum + heat pipe: Good cooling, 150-300W
- Die-cast aluminum + fan: Best cooling, but fan has lifespan risk
Passive cooling (no fan) is recommended for lower maintenance costs.
5. Installation Methods
- Chain mount: Most common, suitable for most factories
- Pendant mount: More stable, for vibration environments
- Surface mount: For low-height warehouses
- Bracket mount: For walls or columns
FAQ
Q: How much energy do LED high-bay lights save vs metal halide?
A: 200W LED replaces 400W metal halide — 50% energy savings, with ~20% higher illuminance.
Q: How long do high-bay lights last?
A: Quality brands offer L70 life ≥50,000 hours — 13 years at 10 hours/day.
