Compared with other lamps, LED panel lights have outstanding advantages: ultra-thin, ultra-bright, ultra-energy-saving, ultra-long life, ultra-saving and worry-free! Green and environmental protection. However, the quality of LED panel lights varies greatly, and consumers do not know how to choose?    

In view of the vicious competition in the market price of flat panel lamps, a large number of substandard products are listed (professionals call it (bad, bad, bad), which has violated the true value of LED energy saving, long life, environmental protection, etc. The significance of the application of technology to the field of integrated ceiling lights has 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 or distinguish the quality of LED panel lights. :  


Look at the overall "power factor of the lamp": low power factor means that the driving power and circuit design used will greatly reduce the life of the lighting! With low power factor, the life of the lighting will not be long no matter how good the lamp bead is used. 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 unqualified products or junk products not only have a short lifespan, but also 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 the reason why LED panel lights need to be equipped with high-quality and high-efficiency driving power! Consumers who do not have a "power factor meter" to detect the power factor of LED lamps, there is another way to use an "amperometer" to detect the second A similar product with the same nominal power, the larger the current and the larger the current harmonics, the greater the actual power consumption, and the less power saving! 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!


Look at the "heat dissipation conditions of lamps and lanterns-materials and structure": the heat dissipation of LED lamps is also very important. For lamps 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, and the light decay will be very large. , The lamp life will be reduced. The heat dissipation materials used are mainly copper, aluminum, and PC. Copper has better heat conduction than aluminum, and aluminum has better heat conduction than PC. Nowadays, radiator materials generally use aluminum more, preferably insert aluminum, car aluminum (aluminum profile) , Extruded aluminum) Secondly, cast aluminum is the worse one, and the heat dissipation effect of insert aluminum is better!


Look at the "lamp bead quality": the quality of the lamp bead is determined by the chip quality and packaging technology.

The quality of the chip determines the brightness and light attenuation of the lamp beads. Good lamp beads not only have high luminous flux, but also have low luminous decay.


Looking at the driving power used by the lamp, the service life of the power supply is much shorter than that of other parts of the lighting. The life of the power supply affects the overall life of the lamp. The theoretical life of the lamp bead is 50,000 to 100,000 hours, while the life of the power supply is 0.2-30,000 hours, the design and material selection of the power supply 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.


Look at the light efficiency: the same lamp bead power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.


Look at the power supply efficiency. The higher the power supply efficiency, the better, and the higher it is, indicating that the power consumption of the power supply itself is smaller and the output power is greater.
