LED anti-natural gas station prices compete for the vicious competition, a large number of unqualified products listed on the contrary to the LED energy saving, long life, environmental protection and other true value, how to distinguish the advantages and disadvantages of LED lamps should proceed from the following aspects:
1. See the overall power factor of the lamp. Power factor is low, 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 lamp life will not be long.
2. See the lamp cooling conditions, materials, structure.LED lamps cooling 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, the light will be great, Lamp life will be reduced.
3. To see the quality of light beads, lamp quality depends on the chip quality and packaging technology.
