Compared with other lamps, the flat panel lamp is a bit very outstanding: ultra-thin, super bright, super energy-saving and over-life, it is a very energy-saving and environmentally friendly product. The quality of the flat lamp in the competitive market of lamps is also very different, and consumers How to choose a flat lamp instead? Here are some factors to buy a flat lamp.

Panel Light

First, look at the overall flat panel light-flat panel power factor

The low power factor means that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lighting! The power factor is low, and the life of the lighting decoration using the best lamp beads will not be long. The power factor is high or low, you can use the "power factor meter" to detect it! General export LED flat lamp power factor requirements reach 0.85 or more. If the power factor is lower than 0.5, it should be said that the unqualified product or waste product not only has a short life, but also the actual power consumption is about twice higher than the nominal, that is, compared with ordinary energy-saving lamps, it does not save electricity at all! Therefore, the editor of China Ceiling Net told everyone: This is why LED flat panel lights need to be equipped with high-quality and high-efficiency driving power!

However, there is no "power factor meter" to detect the power factor of LED lighting consumers, there is another way to use the "ammeter" to detect these two similar products with the same nominal power, the greater the current and the greater the current harmonics, The greater the actual power consumption, 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 life of the overall lighting.

Second, look at the material of the flat lamp-flat lamp heat dissipation conditions

The heat dissipation of LED lighting is also very important. For the same power factor lighting and the same quality lamp beads, if the heat dissipation conditions are not good, the lamp beads work at high temperature, the light attenuation will be great, and the life of the lighting will be reduced. In addition, the editor of China Ceiling Net will tell you again that the heat dissipation materials used are mainly copper, aluminum, and PC. The heat conduction of copper is better than aluminum, and the heat conduction of aluminum is better than PC. Now the heat sink material generally uses aluminum most , The best is the insert aluminum, car aluminum (aluminum profile, extruded aluminum) followed, the worst is cast aluminum, the insert aluminum has the best heat dissipation effect!

Third, look at the quality of the flat lamp-flat lamp lamp beads

The quality of the lamp beads depends on the chip quality and packaging technology. The quality of the chip determines the brightness and decay of the lamp beads. A good lamp bead is not only bright and bright, but also has little light decay.

Fourth, look at the power supply of the flat panel lamp-the flat panel lamp consumes energy


The service life of the power supply is much shorter than that of other parts of the lighting. The service life of the power supply affects the overall life of the lighting. 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. The design and material selection will determine the service life of the power supply. The power drive of aluminum alloy is better than that of engineering plastic. First, it has better heat dissipation. Second, it can effectively protect the parts inside from being crushed and loosened during transportation and use, and reduce the failure rate of power drive.
