LED Tube Light shell accessories theoretical life expectancy of 50000-100000 hours, but the power LED ceiling light is a short board, power supply number is based on the quality of the life is good or bad is usually 3000-20000 many hours of life expectancy, power supply if broken then the whole lamp will light can not afford it. The use of the electronic components within the power supply quality, the design of the power of the resolution power, power factor, stability, temperature value, the use life expectancy.
Power LED Tube Light shell accessories higher the better, the higher the power to clarify their own consumption is smaller, the greater the power output. Like Eneltec and other specifications as the light of the manufacturers of the power supply and light products through the factory is about 24 hours aging test the impact of the piezoelectric irregularities, if power failure the uneven light products, the impact of the piezoelectric quickly broken away, through the aging test can greatly improve product yield. Beads (Chip): Light bead quality resolution on chip quality and packaging skills.
Chip quality resolution LED brightness and the light fades. Good is not bare lamp beads brightly lit high, and the light fades too small, the price difference is particularly large, the same one watt lamp beads, not the same chip and packaging skills to reach 3-10 times the price difference, especially the price low ceiling, and many use chip production lines to manufacture defective products laid, inconsistent color temperature, brightness difference, life expectancy is short.
LED Tube Light lamp shell accessories first and foremost is the heat conduction to the LED beads scattered out of the radiator, the thermal conductivity of aluminum plate data and alloy aluminum plate data related to the amount of other information, if the high thermal conductivity of copper and silver added information, aluminum plate data the thermal conductivity must be high, differentiate the quality of the aluminum plate, the primary side to see the appearance technology, the thermal conductivity of aluminum plate, high pressure resistance, intolerant, over the board after reflow will yellow.
