How to buy LED panel lights - LED lighting experts teach you a few strokes

LED panel lights and other lighting compared advantage is very outstanding: ultra-thin, ultra light, ultra energy saving, long life, super easy worry! Green environmental protection. However, LED panel light quality is great, consumers do not know how to choose? In view of vicious competition in the flat-panel lamp market price fight, a large number of unqualified products listed (professionals call (him, poor goods, rotten goods), has violated the LED energy saving and long life, environmental protection and other real value, contrary to the integrated ceiling in the field of application of LED technology, and seriously affected the healthy development of the integrated ceiling LED panel lights, LED panel lights as manufacturers have the responsibility to introduce and illustrate the method is how to choose LED panel lights or differential LED panel lamp:
, look at the overall lighting power factor "": the low power factor, and illustrate the use of the driving power supply, circuit design is not good, will reduce the lighting life greatly! The power factor is low, the use of good lighting lamp life is not president。 Power factor high or low, with the "power factor meter" can be detected! General export LED flat-panel lamp power factor requirements to achieve more than 0.85. The power factor is less than 0.5, it should be said that the unqualified products or waste products, not only the short life, and the actual power consumption than the nominal is about to double, that is to say, with the ordinary energy-saving lamps, no electricity! So this is the reason why LED lamp driving power supply with high quality, need high efficiency the! No "power factor meter" is used to detect the LED lighting power factor of consumers, there is a way to use the "current" to detect two of similar products in the same nominal power, the greater the current and harmonic current is larger, indicating the actual power consumption is large, it is not at the same time, saving! The current is not stable, the life span and the overall lighting life unfavorable!
two, see "lighting cooling conditions -- materials, structure: radiating LED lighting is also very important, the same power factor and lighting With the quality of the lamp, if the heat condition is not good, light work under high temperature, light will be great, life will reduce lighting. At present, there are copper, aluminum, PC to the cooling material, thermal conductivity of copper is better than aluminum, aluminum heat conduction than PC good, now radiator material is usually made of aluminum is the most, the best is in aluminum sheet, car aluminum (aluminum profiles, aluminium extrusion) times, the worst are made of cast aluminum in aluminum heat sink effect best!
3, see "quality of beads": bulb quality decided on the chip quality and packaging technology. Brand chip is divided into three camps: the first camp in Europe and America, Japan as the representative of the manufacturer, mainly including Cree, OSRAM, Nichia, Toyoda Gosei,; the second camp in the United States, South Korea, China Taiwan, as the representative of the manufacturer, mainly including Puri, Xuming, Seoul, Jing Yuan, Taigu, wide shocks, and new century; the third camp in China as the representative of the manufacturer, mainly Saman, Di Yuan, blue, Silan azure, the United States and other. The chip quality decides the brightness and light bulb. The lamp not only lighting, but also small and light.
4, see using lighting drive power, the use life of power relative lighting of other parts, life is much shorter, the overall life of the lighting affecting the life of power supply, beads of the theory of life in the 5-10 million hours, and the life of the power supply in 0.2 - 3 million hours, power supply design and material choice will determine the service life of the power supply. Appearance with aluminum alloy power driven than engineering plastics, one is the good heat dissipation, and the use of the transport process can effectively protect the inside parts will not be crushed and loose, reduce the driver's fault rate.
5, see light effect: the same bulb power, higher luminous efficiency, brightness is high, the same brightness, power consumption is small more energy-saving.
6, look at the power efficiency, power efficiency, the higher the better, the higher that the smaller the power consumption of the power supply itself, the greater power output.
seven, China's LED lighting safety standards have been introduced, according to the provisions of the national security standard selection of LED lighting.
eight, to see whether the fine workmanship, a good quality LED panel lights, in addition to the above mentioned several major aspects, the fine workmanship is the perfect product of an external embodiment. In short, a good quality of LED panel lights, high-quality driving power, good heat dissipation, high quality chip, conforms to the safety standard of perfect combination! Only emphasize any one party, cannot be called a qualified products!
