LED market price battle vicious competition, listing a large number of substandard products have been contrary to the true value of LED energy saving, long life, and environmental protection, how to distinguish between the merits of LED lamps, from the following aspects:
1, look at the overall "lamp power factor": low power factor, indicating that the drive power usage, the circuit design is not good, it will greatly reduce the lamp life, low power factor, the use of even the best lamp beads lamp life is not president .
2, see "heat lamps conditions - materials, structures": LED heat lamps is also very important, the same power and the same quality of lighting lamp beads factor, if the heat is not good condition, lamp beads at high temperatures, will be very bad light Great, lamp life will be reduced.
3, see the "light bead quality": lamp beads quality depends on the quality of chip and packaging technology.
4, to see the rest of the lamp used in drive power, the power of the life of the lamp relatively speaking, much shorter life expectancy, affect the overall life of the life of the lamp power supply, lamp beads theoretical life of 5-10 million hours, and the power of life in 0.2-3 million hours, power supply design and material selection will determine the power of life.
5, see the light efficiency: the same power lamp beads, light efficiency is higher, the higher the brightness, the same illumination, power consumption smaller, more energy-efficient.
6, see the power efficiency, power efficiency as high as possible, the higher, indicating that the smaller the power consumption of the power supply itself, the greater the power output.
7, is to see whether the safety standards? Our LED lighting safety standards have been introduced, press the safety standards prescribed by the state to select LED lamps. 8, is to see whether the fine work. A good quality LED lamps, in addition to several major aspects mentioned above, but also according to different environments, have different technical requirements, such as moisture, dust, magnetic, anti-lightning.
