First, look at the overall "power factor of lighting": 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 can be detected with a "power factor meter"! Generally, the power factor of exported LED panel lights is required to be above 0.85. If the power factor is lower than 0.5, it should be said that unqualified products or garbage products not only have a short lifespan, but also the actual power consumption is about twice as high as the nominal value. That is to say, compared with ordinary energy-saving lamps, it does not save electricity at all! So , This is why LED flat panel purification lights need to be equipped with high-quality, high-efficiency drive power! Consumers who do not have a "power factor meter" to detect the power factor of LED lighting, there is another way to use an "ammeter" to detect two For similar products with the same nominal power, the larger the current and the larger the current harmonics, the larger the actual power consumption, and the less power saving! At the same time, the current is unstable, which is not good for the life of the lamp bead and the life of the overall lighting!
2. Look at "lighting heat dissipation conditions - material and structure": LED lighting heat dissipation is also very important. Lighting with the same power factor and the same quality lamp beads, if the heat dissipation conditions are not good, the lamp beads work at high temperatures, and the light decay will be reduced. Very large, the lamp life will be reduced. The main heat dissipation materials used are copper, aluminum, and PC. Extruded aluminum) is the second, the worst is cast aluminum, and the heat dissipation effect of insert aluminum is the best!
3. Look at "lamp bead quality": lamp bead quality depends on chip quality and packaging technology.
The quality of the chip determines the brightness and light decay of the lamp bead. Good lamp beads not only have high luminous flux, but also have small light decay.
Fourth, look at the driving power used by the lighting. 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 lighting. The theoretical life of the lamp beads is 50,000-100,000 hours, while the power The service life is between 0.2 and 30,000 hours. The design and material selection of the power supply will determine the service life of the power supply. The appearance of aluminum alloy power drive is better than that of engineering plastics. First, it has better heat dissipation. Second, it can effectively protect the parts inside from being crushed and loosened during transportation and use, reducing the failure rate of power drives.
5. Look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.
6. Look at the power efficiency. The higher the power efficiency, the better. The higher the power, the smaller the power consumption of the power supply itself, and the greater the output power.
