How to identify the quality of integrated ceiling LED panel lights
Compared with other lamps, LED lamps have outstanding advantages: energy saving, long life, and environmental protection. However, the quality of LED lamps varies greatly, and consumers do not know how to choose? In view of the current vicious competition in the market price of flat panel lights, the listing of a large number of substandard products (professionals call it (bad, poor, bad) has violated the true value of LED energy saving, long life, environmental protection, etc. The application of LED technology to the field of integrated ceilings has a significant impact on the healthy development of integrated ceiling LED panel lights. How to distinguish the pros and cons of LED lamps should start from the following aspects:
1. Look at the overall "power factor of the lamp": 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 lamp. With low power factor, the life of the lamp will not be long no matter how good the lamp bead is used. .
The power factor level can be detected with the "power factor meter"! Generally, the power factor of export LED lamps 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 why LED lamps need to be equipped with high-quality, high-efficiency driving power!
For consumers who don’t have a “power factor meter”, another way is to use an “amperometer” to detect two similar products with the same nominal power. 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 lamp!
2. Look at the "heat dissipation conditions of lamps and lanterns-material 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 under high temperature and the light will decline. Very large, the lamp life will be reduced.
At present, the main heat dissipation materials used are copper, aluminum, and PC. Copper has better heat conduction than aluminum, and aluminum has better heat conduction than PC. The flat light radiator materials used in integrated ceilings generally use aluminum the most, and the best is the plug Sheet aluminum, car aluminum (aluminum profile, extruded aluminum) is the second, the worst is cast aluminum, and the insert aluminum has the best heat dissipation effect!
Third, look at the "lamp bead quality": the quality of the lamp bead is determined by the chip quality and packaging technology.
