Compared with other lighting, the advantages of LED panel lights are very prominent: ultra-thin, ultra-bright, ultra-energy-saving, ultra-long service life, saving trouble, and environmental protection. However, the quality of LED panel lights varies greatly, and the common people do not know how to choose?
In view of the current vicious competition in the price of panel lights, a large number of unqualified products are listed, which has violated the true value of LED energy saving, long service life, environmental protection, etc., violated the significance of applying LED technology to the integrated ceiling field, and seriously affected the healthy development of integrated ceiling LED panel lights. As a manufacturer of LED panel lights, it is the responsibility to introduce and explain to everyone, how to choose LED panel lights? Let Anem introduces it in detail.
The low power factor indicates that the driving power and circuit design used are not good, which will greatly reduce the service life of the lighting. The power factor is low, no matter how good the lamp bead is used, the lamp life will not be long.
The level of power factor can be detected with a "power factor meter". Generally, the power factor of export LED panel lights is required to reach 0.85 or more.
If the power factor is lower than 0.5, it should be said that the unqualified product has a short lifespan, and the actual power consumption is about twice as high as the nominal. That is to say, compared with ordinary energy-saving lamps, it does not save electricity at all. So, this is why LED panel lights need to be equipped with high-quality, high-efficiency driving power.
For consumers who don't have a "power factor meter" to detect the power factor of LED panel lighting, there is another way to use an "amperometer" to detect two similar products with the same nominal power. The greater the current and the greater the current harmonics, it means that the actual power consumption is larger, and the less power is saved. At the same time, the current is unstable, which is detrimental to the life of the lamp beads and the overall lighting.
The heat dissipation of LED panel lighting is also very important. For lighting with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperatures, the light decay will be great, and the life of the lighting will be reduced.
At present, the main heat dissipation materials used are copper, aluminum, PC, copper has better heat conduction than aluminum, and aluminum has better heat conduction than PC. Nowadays, aluminum is generally used as the most radiator material, and the best is insert aluminum, car aluminum (aluminum profiles, extruded aluminum) followed by cast aluminum, and the insert aluminum has the best heat dissipation effect.
The quality of the lamp beads is determined by the chip quality and packaging technology.
Compared with other parts of the lighting, the service life of the power supply is much shorter. The life of the power supply affects the overall life of the lighting. The theoretical life of the lamp bead is 50,000 to 100,000 hours, and the life of the power supply is 0.2 to 30,000 hours. The design and material selection will determine the service life of the power supply.
The appearance of the power drive with aluminum alloy is better than that of engineering plastics. One is that it has better heat dissipation. The other is that the parts inside can be effectively protected from being crushed and loose during transportation and use, and the failure rate of the power drive is reduced.
