Linear vs. DOB LED Street Lights – What’s the Difference?
Please refer below format as difference!
| Name | Linear LED STREET LIGHT | DOB LED STREET LIGHT |
| Driver method | Linear | Non-isolated driver solution |
| Input Voltage | 200-265V | 100-265V |
| Convension Efficiency | 75-85% efficiency lower | 90% high efficiency |
| Electromagnetic compatibility | Easy pass to EMC | Difficult to pass EMC |
| Anti-surge properties | Strong | Middle |
| Lifetime | Long (no electrolytic capacitance) | General (with electrolytic capacitors and transformers) |
| Region application | The power grid input voltage is stable, and the lamp stroboscopic requirements are not high; Countries with strict EMC requirements for lamps | The power grid input voltage fluctuation is large, the lamp stroboscopic requirements of the region: no requirements for EMC certification |
| Advantages | Low cost, strong surge resistance, mature program, can pass EMC 2. The structure is simple, relatively stable, the cost has an advantage, and the price of certification is low | can do a wide voltage, the input voltage can be 100-265V, and drive is similar, but the drive components are moved to the lamp board, you can do no flicker |
| Defect | Input voltage range is narrow, can not do wide voltage, stroboscopic | At present, the surge resistance - general (chip factory is improving) too high EMC cost, electrolytic capacitors, high temperature will have a certain impact on life |
