The advantages and disadvantages of high-power LED lamps, the vicious competition of high-power LED market price, and the listing of a large number of unqualified products have violated the real value of high-power LED energy saving, long life, environmental protection, etc. How to distinguish the advantages and disadvantages of high-power LED lamps should start from the following aspects:
1. Look at the overall "power factor of lamps": the low power factor indicates that the poor design of driving power supply and circuit will greatly reduce the service life of lamps. The low power factor will not last long even if the lamp beads are used well.
2. Look at "heat dissipation conditions of lamps - materials and structures": heat dissipation of high-power lamps is also very important. Lamps with the same power factor and lamps with the same quality will have great light attenuation and reduce lamp life if the heat dissipation conditions are not good and the lamps work at high temperature.
Look at "lamp bead quality": lamp bead quality depends on chip quality and packaging technology. 4. As for the driving power supply used by the lamps, the service life of the power supply is much shorter than that of other parts of the lamps. The service life of the power supply affects the overall service life of the lamps. The theoretical service life of the lamp beads is 50000-100000 hours, while the service life of the power supply is 20000-30000 hours. The design and material selection of the power supply will determine the service life of the power supply. 5. Light efficiency: for the same lamp bead power, the higher the light efficiency, the higher the brightness, and the same lighting brightness, the smaller the power consumption, the more energy-saving. 6. In terms of power efficiency, the higher the power efficiency, the better, the higher, indicating that the smaller the power consumption of the power supply itself, the greater the output power. 7 is to see if it meets the safety standards? The safety standard of high-power LED lamps has been issued in China. Please select high-power LED lamps according to the national safety standard. 8 is to see if the workmanship is fine. A high-power LED lamp with good quality has different technical requirements, such as dampproof, dustproof, antimagnetic, lightning protection, etc. in addition to the main aspects mentioned above, according to different use environments.
