Seven steps to choose LED panel lights or to identify the quality of LED panel lights

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

In view of the vicious competition in the market price of flat panel lights, a large number of unqualified products are listed (professionals call it (inferior goods, bad goods, rotten goods), which has violated the real value of LED energy saving, long life, environmental protection, etc. The application of technology to the field of integrated ceilings has seriously affected the healthy development of integrated ceiling LED panel lights. As a manufacturer of LED panel lights, this responsibility is introduced to explain how to choose LED panel lights or identify LED panel lights. :

First, look at the overall "power factor of lighting":

The low power factor means that the driving power supply and the circuit design are not good, which will greatly reduce the service life of the lighting! The power factor is low, and the lighting life of the lamp bead is not long. The power factor is high and low, and it can be detected by “power factor meter”! The power factor requirement of general export LED panel light is above 0.85. The power factor is lower than 0.5. It should be said that the unqualified product or the garbage product not only has a short life span, but also the actual power consumption is about twice as high as the nominal value. That is to say, compared with the ordinary energy-saving lamp, it does not save electricity at all! This is the reason why LED panel lights need to be equipped with high-quality, high-efficiency driving power supply. There is no "power factor meter" for consumers who detect the power factor of LED lighting. Another way is to use "current meter" to detect two Similar products with the same nominal power, the larger the current and the greater the current harmonics, indicating that the actual power consumption is large, and the more power is not saved! At the same time, the current is unstable, which is detrimental to the life of the lamp bead and the life of the overall lighting!

Second, look at "lighting conditions for lighting - materials, structure":

LED lighting is also very important for heat dissipation. The same power factor lighting and the same quality of the lamp bead, if the heat dissipation conditions are not good, the lamp bead works at high temperature, the light decay will be great, and the lighting life will be reduced. The heat dissipating materials used mainly include copper, aluminum and PC. The thermal conductivity of copper is better than that of aluminum. The thermal conductivity of aluminum is better than that of PC. Now the radiator material is generally the most aluminum, the best is aluminum insert, aluminum aluminum (aluminum profile, After the aluminum is extruded, the worst is cast aluminum, and the insert aluminum has the best heat dissipation effect!

Third, look at the "light quality": the quality of the lamp is determined by the chip quality and packaging technology.

The quality of the chip determines the brightness and light decay of the lamp. A good lamp bead is not only bright but also light.

Fourth, look at the driving power used in 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 is between 50,000 and 100,000 hours, while the life of the power supply is between 0.2 and 30,000 hours. The design and material selection will determine the life of the power supply. The appearance of aluminum alloy power drive is better than engineering plastics, first, its heat dissipation is good, and second, the transportation and use process can effectively protect the inside parts from being crushed and loosened, reducing the power drive failure rate.

Fifth, look at the light effect:

The same lamp power, the higher the light efficiency, the higher the brightness, the same illumination brightness, the smaller the power consumption, the more energy saving.

Sixth, look at the power efficiency:

The higher the power efficiency, the better. The higher the power consumption, the smaller the power consumption of the power supply itself.

Seventh, China's LED lighting safety standards have been introduced, please select LED lighting according to the national safety standards.
