三防灯与普通灯具对比
冲洗场所需要真正密封的灯体,而不是看起来结实。
"看起来工业风"不等于防护等级。钢体加扩散罩的普通灯具在冷库里会积冷凝水,在冲洗区会直接失效。
| 对比维度 | 选项 A | 选项 B | 优胜 |
|---|---|---|---|
| Ingress protection | IP65 to IP69K, gasketed body | IP20 to IP44 | Vapor tight |
| Cleaning | Pressure wash and disinfectant safe | Damp wipe only | Vapor tight |
| Materials | Polycarbonate or fibreglass, stainless clips | Powder-coated steel with a diffuser | Vapor tight |
| Condensation | Vented or sealed designs for cold rooms | Prone to internal condensation | Vapor tight |
| 成本 | 20-60% higher | 基准 | Standard |
| Best fit | Food plants, car washes, cold stores | Warehouses, workshops, retail backrooms | 视应用而定 |
结论
食品厂、洗车场、冷库以及任何会被水枪冲洗的区域,选 IP65-IP69K 三防灯,并确认密封材质与卡扣结构,而不只是看 IP 数字。
