How to choose and buy:

LED flat lamp 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 flat lamp quality varies greatly, consumers do not know how to choose?
In view of the flat lamp market price fight closely of vicious competition, a large number of unqualified products listed (professionals say the (bastard, difference of goods, goods rot), has violated the LED energy-saving, long life, environmental protection and real value, contrary to the LED technology application to the field of integrated ceiling, and a serious impact on the healthy development of the integrated ceiling led plate lamp, as LED lighting panel manufacturers have the responsibility to introduce and explain how to choose the quality of the LED flat lamp or differential LED flat lamp:
First, look at the overall "lighting power factor": low power factor, illustrate the driving power supply, circuit design is not good will greatly reduce the service life of the lamp! Low power factor, the use of even the best lamp lighting life also won't grow. 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 no! "Power factor" 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, the current electricity! The life span is not stable, and the overall lighting adverse life!
Second, the "heat sink for lighting, material and structure: heat dissipation of LED lighting is also very important, lighting of the same power factor and the same quality of beads, if the heat dissipation condition is not good, beads in the high temperature working, attenuation will be great, lamp life will be reduced. The cooling materials are copper, aluminum, PC, thermal conductivity of copper is better than aluminum, aluminum thermal conductivity 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 is best!
Third, "light quality: quality depends on the quality of the chip and chip package technology.
The chip quality decides the brightness and light bulb. The lamp not only lighting, but also small and light.
Fourth, 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.
Fifth, Look at the light bulb power efficiency: the same light effect, higher brightness, higher brightness, lighting the same power consumption, smaller, more energy saving.
Sixth, 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.
Seventh, China's LED lighting safety standards have been introduced, according to the national standard of safety selection LED lighting. Pathfinder lighting LED lamp has passed the CE certification, ROSH certification.

Maintenance attention:

1.before cleaning the lamps, please be sure to turn off the power supply.
2. please use a dry or dry cloth to clean.
3.Do not use chemicals or corrosive things to clean.
