How to choose the high quality LED lamp

LED market prices fight the vicious competition, a large number of unqualified products listed on the contrary to the LED energy saving, long life, environmental protection and other real value, how to distinguish the advantages and disadvantages of LED lamps, should proceed from the following aspects:

1, see the overall "lamp power factor": low power factor, indicating the use of the drive power, circuit design is not good, will greatly reduce the lamp life, power factor is low, the use of no longer lamp beads life will not long The

2, see the "lamp cooling conditions - materials, structure": LED lighting is also very important, the same power factor lamps and the same quality of the lamp beads, if the heat conditions are not good, the lamp beads at high temperatures, Large, lamp life will be reduced.

3, see "light bead quality": lamp quality depends on the quality of the chip and packaging technology.

4, to see the use of the lamp drive power, power supply life relative to other parts of the lamp, the life is much shorter, the life of the lamp life of the overall life, lamp beads of the theoretical life of 5-10 million hours, and power Life expectancy of 0.2-3 million hours, power supply design and material selection will determine the power supply life.

5, see light effect: the same lamp beads power, the higher the luminous efficiency, the higher the brightness, the same brightness, power consumption, the more energy-efficient.

6, see the power efficiency, power efficiency, the higher the better, the higher the power itself, the smaller the power consumption, the greater the output power.
