How to buy ultra-thin ultra-bright energy-saving LED flat panel light?

Compared with other lighting products, LED panel lights have outstanding advantages: ultra-thin, ultra-bright, ultra-energy-saving, long-life, and saving worry! Green environmental protection. 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 for flat panel lamp prices, a large number of unqualified products went on the market (professionals have called it (bad goods, bad goods, bad goods)) and have violated the real value of LED energy saving, long life, and environmental protection. The application of technology to the significance of the integrated ceiling area has seriously affected the healthy development of integrated ceiling LED panel lights. As a manufacturer of LED panel lights, this responsibility is to introduce and explain how to select LED panel lights or identify the quality of LED panel lights. :

First, look at the overall “power factor of lighting”: low power factor, indicating that the use of the drive power supply, circuit design is not good, will greatly reduce the service life of lighting! Power factor is low, the use of no matter how long the lamp life will not be long . The power factor level can be detected with the “power factor meter”! The power factor of the general export LED flat panel lamp is required to reach 0.85 or more. Power factor is lower than 0.5, it should be said that unqualified products or garbage products, not only short life, and the actual power consumption is about twice higher than the nominal, that is, compared with ordinary energy-saving lamps, simply do not save power! So, this is why LED panel lights need to be equipped with high-quality, high-efficiency driving power! There is no “power factor meter” to detect LED lighting power factor consumers, there is a way to use the “amperometer” to detect two A similar product with the same nominal power, the greater the current and the greater the current harmonics, indicating that the actual consumption of electricity is large, and the less power it saves! At the same time, the current is not stable, which is detrimental to lamp life and overall lamp life!

Second, look at the “lighting heat conditions – materials, structures”: LED lighting is also very important heat, the same power factor lighting and the same quality of the lamp, if the heat conditions are not good, the lamp beads work at high temperatures, light failure will Large, 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. Nowadays, the heat sink material is generally made of aluminum, and the best is aluminum insert, aluminum (aluminum), (Aluminum extrusion) followed, the worst is cast aluminum, insert aluminum best cooling effect!

Third, look at the “lamp beads quality”: lamp beads quality is determined by the chip quality and packaging technology.

The quality of the chip determines the brightness and light decay of the lamp beads. A good lamp is not only bright and bright, but also has a low light decay.

Fourth, look at the lighting used to drive the power supply, the service life of the power supply relative to other parts of the lighting, the life expectancy is much shorter, the life of the power supply affects the overall life of the lighting, lamp beads theoretical life of 5-10 million hours, and the power supply The service life is 0.2-30 thousand 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 supply drive is better than engineering plastics, first, its good heat dissipation, and second, the transportation and use of the process can effectively protect the inside parts are not crushed and loose, reducing the power-driven failure rate.

Fifth, see the light effect: the same lamp power, the higher the luminous efficiency, the higher the brightness, the same brightness, the smaller the power consumption, the more energy-efficient.

Six, look at the power efficiency, the higher the power efficiency as possible, the higher, indicating that the power consumption of the power itself is smaller, the greater the power output.
