Affect life span of the power switch times: Most power has capacitor input type rectifier circuit Tianshui LED rainproof power suppliers, in the electric power was turned, will produce surge current Tianshui specialized in producing LED flashing power supply, causes the switch contacts to fatigue, cause contact resistance increases and adsorption problems. Theorized that life expectancy during power, the number of switch-off about 10,000 times. Affect affect electrolytic capacitor LED power life: the sealing portion of the electrolytic capacitor will leak electrolyte gasification LED waterproof power supply, this phenomenon will accelerate as the temperature rises and Tianshui LED waterproof power supply manufacturers, is generally believed that each temperature rise 10 ℃, the leak rate will increase to 2 times. Therefore we can say electrolytic capacitors determines the service life of the power supply unit. If you use 105 degrees, life of 10,000 hours of high-temperature electrolytic capacitors, electrolytic capacitor according to the prevailing life estimation formula "for each 10 degrees, doubling the life," then it is 95 degrees below ambient operating life of 20,000 hours at 85 degrees environment working life of 40,000 hours. LED driver power supply to normal working life depends on the supply used life of electrolytic capacitors, electrolytic capacitor life and life itself depends on the capacitance and temperature. Capacitance Temperature 65 ℃ life can only be guaranteed when about 80,000 hours; the life of the capacitor temperature 75 ℃, only about 40,000 hours guarantee; lifetime capacitor temperature at 85 ℃ only guarantee about 20,000 hours; capacitance when temperature 95 ℃ can only guarantee the life of about 10,000 hours; From the above projections: electrolytic capacitor temperature rise 10 ℃, life will be halved.
