How to choose right led panel light?
LED panel light compared with other lighting, there 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 vicious competition, a large number of unqualified products listed have been contrary to the true value of the LED energy-saving, long life, environmental protection, etc. Seriously affected the healthy development of integrated ceiling LED panel lights, as manufacturers for LED panel lights, have the responsibility to introduce and explain how to select or identify good or bad LED panel light.
First, look at the whole "lighting power factor": the power factor is low, indicating that the drive power supply, circuit design not well, will greatly reduce the life of the lighting. If power factor is low, the use of better chip, life will not be long. Power factor level, with "power factor meter" can be detected! General export LED panel light required to be achieved power factor above 0.85. Power factor of less than 0.5, it should be substandard products or refuse products, not only short-lived, but the actual consumption of electricity is about twice higher than the nominal.
Second, look at "Lighting cooling conditions - materials, structures": LED lighting heat dissipation is also very important. With the same quality lamp beads and power factor, if the heat dissipation is not good, lamp work beads at high temperatures, the light fades will be great, lighting life will be reduced. Currently, the heat sink material is mainly used in copper, aluminum, PC, better thermal conductivity than aluminum, copper, aluminum, a good thermal conductivity surpasses PC, now up to the heat sink material is typically aluminum, most preferably aluminum inserts, Aluminium (Al profiles, extruded aluminum), followed by the worst is cast aluminum, aluminum inserts cooling effect is best!
Third, look at "lamp beads quality": Lamp quality depends on the quality and chip packaging technology.
Fourth, look at the lighting used in other parts of the drive power, the power of life relatively lighting, the life expectancy is much shorter, the power of life affect the overall life of the lighting, the theoretical life of lamp beads in the 5-10 million hours, and the life of driver at 0.2 -3 million hours, power supply design and material selection will determine the life of the power supply.
Fifth, look at luminous efficiency: the same power lamp beads, luminous efficiency is higher, the higher the brightness, the same illumination, power consumption is smaller, more energy-efficient.
Sixth, look at the power efficiency, power efficiency, the higher the better, higher power efficiency indicates that the smaller power consumption of the power supply itself, the greater the power output.
Seventh, to see whether the fine workmanship, a good quality LED panel lights, in addition to several major aspects mentioned above, fine workmanship is an external manifestation of the perfect product.
