How to identify the quality of the merits of the LED panel light

LED lamps and other lamps compared very prominent advantages: energy saving, long life, green. However, LED panel lightquality vary widely, and consumers do not know how to choose? View of the battle was vicious competition in the market priceof the flat LED panel light, a large number of substandard products listed (professionals call it (sub-standard, poor goods, bad lot), contrary to the real value of LED energy saving, long life, environmental protection, contrary to LED technology is applied tothe significance of the field of integrated ceiling, and seriously affected the healthy development of the integrated ceiling LEDpanel light how to distinguish the pros and cons of  LED panel light should be in the following aspects:

First, look at the whole "lighting power factor: power factor is low, indicating that the drive power circuit design is not good, it willgreatly reduce the life of the lamp, the power factor is low, even the best lamp beads lamp life is not president.

    High and low power factor, can be detected with the "power factor table"! General export LED panel should reache 0.85power factor requirements. The power factor is less than 0.5, it should be said that substandard products or trash products,not only short life, and the actual power consumption to about twice than the nominal, that is, than with ordinary energy-saving lamps, and simply do not power-saving! So, this is why LED panel light need to be equipped with high-quality, high-efficiencydrive power of reason!

    Without lighting power factor meter consumers, there is a way "ammeter to detect similar products with the same twonominal power, the greater the current, the greater the current harmonics, indicating that the actual consumption of electricity,also less power saving! Meanwhile, the current instability, detrimental to the life of the lamp beads and overall lamp life!

Second, "heat lamps conditions - materials, structure is very important: LED heat lamps, lamps of the same power factor andthe same quality lamp beads, heat conditions is not good, the lamp beads at high temperatures, light failure will The greatlamp life will be reduced.
    Currently, the use of the heat dissipating material is mainly copper, aluminum, PC, copper, the thermal conductivity is better than aluminum, a good thermal conductivity of aluminum than the PC, the heat sink material of the plate light Usuallyaluminum most car aluminum (aluminum, extruded aluminum) the worst is cast aluminum, aluminum inserts the bestcooling effect!

    If using air convection cooling must handle circuit, power supply insulation problem. Otherwise, lamps work in a more humid environment, prone to short circuit, causing accidents!

Third, look at the the lamp beads quality: the quality of the lamp beads depends on the chip quality and packaging technology.

  Chip brand is divided into three camps:

 The first camp to Europe and the United States, Japan, on behalf of manufacturers, including Cree, Osram, Nichia, Toyoda Gosei, etc.;

    The second camp, represented by the United States, South Korea, China Taiwan manufacturers, including Puri, Xuming,Seoul, wafer, Thai Valley, Guang Jia, new century;

    The third camp as the representative to the domestic manufacturers, Sanan, Di Yuan, Blu-ray, the SILAN AZURE, RoadAmerica and other. The chip quality determines the brightness of the lamp beads light fades. Good lamp beads not only bright lighting, and light fades.

    The fourth parts of life is relatively light to see drive power lamps, power, life is much shorter, the life of the power to affectthe overall life of the lamps, lamp beads theoretical life of 5-10 million hours, and the power life in 0.2-3 ten thousand hours,the power of design and material selection will determine the service life of the power.

The fifth, Light efficiency: the same lamp beads power, higher luminous efficiency, the higher the brightness, the samelighting brightness, low power consumption is smaller, more energy-efficient.
