The price of LED market is in vicious competition. The listing of a large number of unqualified products has violated the real value of LED energy saving, long life and environmental protection. How to distinguish the advantages and disadvantages of LED lamps should be started from the following aspects:
1、 Look at the overall "power factor of lamps": a low power factor indicates that the driving power supply and circuit design used are not good, which will greatly reduce the service life of lamps. A low power factor will not prolong the service life of lamps no matter how well they are used.
2、 Look at "lamp heat dissipation conditions - material and structure": LED lamp heat dissipation is also very important. Lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperature, the light attenuation will be great, and the lamp life will be reduced.
3、 See "lamp bead quality": lamp bead quality depends on chip quality and packaging technology.
4、 Looking at the driving power supply used by the lamp, the service life of the power supply is much shorter than that of other parts of the lamp. The service life of the power supply affects the overall service life of the lamp. The theoretical service life of the lamp bead 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、 Look at the light effect: the higher the light effect is, the higher the brightness is. The lower the power consumption is, the more energy-saving is.
6、 Look at the power efficiency. The higher the power efficiency, the better. The higher the power efficiency, the smaller the power consumption of the power supply itself, and the greater the output power.
7、 See whether it meets the safety standards. China's safety standards for LED lamps have been issued. Please select LED lamps according to the national safety standards.
