LED panel light is a upscale indoor lighting, its external borders made from aluminum by anodic oxidation, the light source is LED, the entire lighting design beautiful and simple, luxurious atmosphere, both good lighting effects, but also gives brings a feeling of beauty. LED panel lights unique design, high transmittance of light through the light guide plate to form a homogeneous plane glow, illumination uniformity, light, soft, comfortable yet bright, can relieve eye fatigue. LED panel lights can also radiation, does not irritate the pregnant women, the elderly, children’s skin.
Compared with other lighting products, LED panel lights are very prominent advantages: ultra-thin, ultra-bright, ultra energy-efficient, long life, ultra-easy peace of mind! Green. However, LED panel light quality varied widely, consumers do not know how to choose? Given the current market price of flat-panel lights fight the vicious competition, a large number of substandard products to market (professionals call it (sub-standard and poor goods, bad lot) , has violated the LED energy-saving, long life, environmental protection and other real value, contrary to the LED technology to the field of integrated ceiling meaningful and integrated ceiling seriously affected the healthy development of LED panel lights, Manufacturers for LED panel lights have the responsibility to introduce and explain how to choose LED Panel lights or LED panel lights to identify good and bad ways:
First, look at the whole “lighting power factor”: if the power factor is low, indicating that circuit design of lighting will greatly be reduced. Also, if power factor is low, the use of even the best LED lighting life is not president . Power factor level, with the “power factor meter” can be detected. General export LED panel light power factor required to achieve above 0.85. Power factor is less than 0.5, it should be said substandard products or refuse products, not only short-lived, and the actual electricity consumption to be higher than the nominal about twice, that is, compared with the ordinary energy-saving lamps, simply not saving. So, this is why LED panel light needs with high-quality, high-efficiency drive power of reason. There is no “power factor meter” is used to detect power factor LED lighting to consumers, there is a way to use the “meter” to test two a nominal power of the same similar products, the greater the current and current harmonics greater, indicating the actual electricity consumption is large, but also the less saving! Meanwhile, the current instability, and the overall life of the lamp beads adverse lighting life!
Second, look at “Lighting cooling conditions – materials, structures”: LED lighting heat is also very important, the same lighting and power factor with the quality of the lamp beads, if the conditions are not good heat dissipation, light bead work at high temperatures, the light fades will be greatly reduced. Currently, the use of the heat sink material are copper, aluminum, PC, thermal conductivity of copper than aluminum, PC better off than the thermal conductivity of aluminum, are most aluminum radiator materials in general, preferably for the insert piece, aluminum die-casting aluminum (Al profiles, extruded aluminum), followed by the worst is cast aluminum, aluminum inserts cooling effect is best.
Third, look at “light bead quality”: LED chip quality depends on the quality and packaging technologies.
Chip Brand of three camps:
The first camp to Europe, America, Japan, as the representative of manufacturers, including Cree, Osram, Nichia, Toyoda Gosei, etc.;
Second camp in the United States, South Korea, China Taiwan as the representative of manufacturers, including Bridgelux, Seoul, Epistar, etc.;
Fourth, drive power. The power of life relative to other parts of lighting, the life expectancy is much shorter, the power of life affect the overall life of lighting, lamp beads theoretical life of 5-10 million hours, and the power of life of 0.2 -3 million hours, power supply design and material selection will determine the power of life. Aluminum exterior with a good power-driven than plastic, one of its good heat dissipation, and second, transport and use can effectively protect the inside of the parts are not to be crushed and loose, lower power drive failure rate.
Fifth, luminous efficiency. Based on the same power lamp beads, light efficiency is higher, the higher the brightness, the same illumination, power consumption is smaller, more energy efficient.
Sixth, power efficiency, the higher the better power efficiency, higher, indicating that the power consumption of the power supply itself is smaller, the greater the power output.
Seventh, China’s LED lighting safety standards have been introduced, according to state regulations, please choose LED lighting safety standards.
Eighth, a good quality LED panel lights, in addition to several key aspects mentioned above, the workmanship is an external manifestation of the perfect product. In short, a good quality LED panel lights, drive power is high quality, good heat dissipation, high-quality chips, meet the safety standards of several aspects of the perfect combination! Merely emphasized that any party can not be called a qualified products !
