Integrated ceiling LED lights how to choose integrated ceiling LED panel lights

Compared with other lighting products, LED panel lights have outstanding advantages: ultra-thin, super-bright, ultra-energy-saving, long-life, and saving worry! Green. However, the quality of LED flat panel lamps varies greatly, and 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 substandard products are listed (professionals call it (bad goods, bad goods, bad goods), Has violated the real value of LED energy saving, long life, environmental protection, and violated the significance of applying LED technology to the integrated ceiling area, and seriously affected the healthy development of integrated ceiling LED panel lights, as a manufacturer of high-end LED panel lights, No shadow angle integrated lighting has this responsibility to introduce and explain how to choose the LED panel light or identify the LED panel light is good or bad:

First, look at the overall "power factor of lighting": low power factor, indicating that the use of power supply, circuit design is not good, will greatly reduce the service life of the lamp! Power factor is low, the use of a good lamp 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 as high 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 drive 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 is saved! At the same time, the current is unstable, and it is detrimental to the lamp life and the overall lighting life!

Second, look at the "heating conditions of lighting - 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 decline will Large, lighting life will be reduced. The heat-dissipating materials used mainly include copper, aluminum and PC. The heat 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 one 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 by the drive power: the 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 Lifespan 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 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.

Sixth, look at the power efficiency: The higher the power efficiency is, the better, and the higher, the smaller the power consumption of the power supply itself, the greater the output power.
