Compared with other lamps and lanterns the advantage of LED bulb are very outstanding energy saving, long life, and environmental protection. Its quality varies widely. However, ordinary people don’t know how to choose? As one of the led bulb manufacturers, we introduce four ways about how to choose the LED lamps and lanterns, or identify the quality of LED lamps and lanterns:
- look at the whole “power factor”: low power factor means the drive power supply, and circuit design is not okay, which will significantly reduce the use life of lamps and lanterns! If power factor is low, using good light bead its life will not long. “Power- factor indicator detect whether power factor is high or not! General export LED lamp power factor above 0.85 is required. Power factor lower than 0.5, it should be said unqualified products or junk. Because not only the life is short, and the actual consumption of electricity is twice higher than nominal. That is to say, with the ordinary energy-saving lamps, have no electricity!
- see the “lamps and lanterns of the cooling conditions, materials, structure, LED lamps, and lanterns of heat dissipation is also very important, the lamps and lanterns of same power factor and the quality of lamp bead, if the cooling conditions are bad, lamp bead work under high temperature, the light failure will be very big, lamps and lanterns of life will be reduced.
- see the cooling conditions of “lamps and lanterns –materials, structure: heat dissipation is also very important. With the same power factor and the quality of lamp bead, if the cooling condition is dangerous, lamp bead work under high temperature, the light failure will be very big, lamps and lanterns of life will be reduced.
- see “lamp bead quality”: lamp bead quality depends on the chip quality and packaging technology. Chip brand in three major groups: the first camp represented by Europe and the United States, Japan’s manufacturers. The second camp represented by the United States, South Korea, China Taiwan manufacturers; The third faction represented by domestic led bulb manufacturers.
Four, see driver power supply used by the lamps and lanterns: compared with other parts of the lamps and lanterns, power supply’s life time is shorter, and affect the whole life of lamps and lanterns. Lamp bead life is 5-100000 hours in theory, and the life of the power supply is 2000 -30000 hours. Power supply design and material choice determine power life time.
In a word, a good quality LED lamps and lanterns, is high quality driver power supply, good heat dissipation and high quality (chips) lamp bead, conforming to safety standards for several aspects of the perfect combination! Emphasis on any one party only, cannot be called a qualified product! To do this, consumers when choosing LED lamps and lanterns, above several important aspects must be taken into account comprehensively, so as not to cause economic loss!
