The advantages and disadvantages of high-power LED lamp […]
The advantages and disadvantages of high-power LED lamps, the vicious competition of high-power LED market price, the listing of a large number of unqualified products has violated the real value of high-power LED energy saving, long life, environmental protection, etc. How to distinguish high-power LED lamps The advantages and disadvantages should be started from the following aspects:
1 Look at the overall "power factor of the luminaire": the power factor is low, indicating that the driving power supply and circuit design used are not good, which 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.
2 look at "lighting conditions of lamps - materials, structure": high-power lamps are also very important for heat dissipation, the same power factor lamps and the same quality of the lamp beads, if the heat dissipation conditions are not good, the lamp beads work at high temperatures, the light decay will be very Large, the life of the lamp will be reduced.
3 look at "light quality": the quality of the lamp is determined by the chip quality and packaging technology.
4 Look at the driving power used by the luminaire. 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 In the case of 0.2-3 million hours, the design and material selection of the power supply will determine the service life of the power supply.
5 look at the 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.
6 Look at the power efficiency, the higher the power efficiency, the higher, the higher the power consumption of the power supply itself, the greater the output power.
7 is to see if it meets safety standards? China's high-power LED lighting safety standards have been introduced, please select high-power LED lamps according to national safety standards.
8 is to see if the work is fine.
A good quality high-power LED lamp, in addition to the above-mentioned several main aspects, also according to different use environments, there are different technical requirements, such as moisture, dust, anti-magnetic, anti-lightning and so on.
