The vicious competition of LED market price stifling, 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 start from the following aspects:
Power Factor
Low power factor, indicating that the driving power supply used, the circuit design is not good, will greatly reduce the service life of the luminaire, the power factor is low, and the life of the lamp using the lamp bead is not long.
Heating conditions of lamps – materials, structures
LED lamps are also very important for heat dissipation. Lamps of the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads work at high temperatures, and the light decay will be large. Lamp life will be reduced.
LED Chips
The quality of the lamp is determined by the chip quality and packaging technology.
Drvier
The service life of the power supply is much shorter than that of other parts of the luminaire. The life of the power supply affects the overall life of the luminaire. The theoretical life of the lamp bead is 50,000-100,000 hours, and the life of the power supply is 0.2-30,000 hours, power supply design and material selection will determine the life of the power supply.
Light effect
The same lamp power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the smaller the power consumption, the more energy saving.
Power efficiency
The higher the power efficiency, the higher, the higher the power consumption of the power supply itself, the greater the output power.
