As the current market price of flat-panel lights fights vicious competition, the listing of a large number of non-conforming products ( sub-standard and poor goods, a bad lot ), has violated the true value of LED energy saving, long life, environmental protection, contrary to the significance of the application of LED technology to the field of the integrated ceiling and seriously affected the healthy development of integrated ceiling LED panel lights.
First, look at the overall " lamp power factor ": if the power factor is low, indicating power supply, circuit design used properly, will greatly reduce the lamp life, low power factor, no matter how light the use of beads lamp life is not the president.
Second, look at " heat lamps conditions - materials, structures ": LED lighting heat is also very important, the same quality of lamps and lamp beads with power factor, if the heat is not good condition, lampwork beads at high temperatures, the light fades will great, lamp life will be reduced.
Third, look at " lamp bead quality": lamp beads quality depends on the quality and chip packaging technology. Explosion-proof led exit signs https://www.eneltec-led.com/led-explosion-proof-lights/led-explosion-proof-exit-lights.html
Fourth, the use of lighting to see other parts of the drive power, the relative power of the lamp life, the life expectancy is much shorter, the overall impact on the life of the lamp power, the theoretical life of lamp beads 5-10 million hours, and the power of life in the 0.2-3 million hours, power supply design and material selection will determine the life of the power supply.
Fifth, check 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. best led headlights http://bestledheadlight.com/
Six, check the power efficiency, power efficiency as high as possible, the higher, indicating smaller power supply itself, the greater the power output.
Seven, check the safety standards? Our LED lighting safety standards have been promulgated, press the safety standards prescribed by the state to select LED lamps.
