The vicious competition of market price of led industrial lamps and lanterns, the listing of a large number of unqualified products have violated the real value of LED energy saving, long life, environmental protection, etc., and LED lamps and lanterns market is facing a severe test! How to distinguish the advantages and disadvantages of led industrial lamps and lanterns should start from the following aspects:
1. Quality of lamp beads
The quality of lamp bead depends on chip quality and packaging technology.
2. Look at the driving power supply used by the lamp
Compared with other parts of lamps, the service life of power supply is much shorter. The service life of power supply affects the overall service life of lamps. The theoretical service life of lamp beads is 50000-100000 hours, while the service life of power supply is 20000-30000 hours. The design and material selection of power supply will determine the service life of power supply.
3. Heat dissipation conditions of lamps - materials and structures
Heat dissipation of LED lamps is also very important. For lamps with the same power factor and lamps with the same quality, if the heat dissipation conditions are not good, the lamp beads work under high temperature, the light attenuation will be great, and the lamp life will be reduced.
4. Power efficiency
The higher the power efficiency is, the better and the higher the power efficiency is, indicating that the smaller the power consumption of the power supply itself is, the greater the output power is.
5. Power factor of overall lamps
The low power factor indicates that the poor design of driving power supply and circuit will greatly reduce the service life of lamps and lanterns, and the lamp life will not be long if the lamp beads are used well.
6. look at the effect of light.
The same lamp bead power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the smaller the power consumption, the more energy-saving.
7. See if the workmanship is fine
A good quality led industrial lamp has different technical requirements, such as moisture-proof, dust-proof, antimagnetic, lightning proof, etc. in addition to the above-mentioned several main aspects, according to different use environment.
8. See if it meets the safety standards
China's LED lighting safety standards have been issued, please select LED lighting according to the national safety standards.
