The LED lamp has long service life


The life of LED chips is generally more than 100 thousand hours. But why is the service life of the general LED lamps sold on the market only 10 thousand to more than 20 thousand hours? This depends mainly on the life of the electrolytic capacitor in the power supply of the LED lamp. The driving power of 3W and 5W bulbs has long life capacitors instead of electrolytic capacitors. Although the cost has been greatly improved, the service life of the whole lamp has increased to more than 35000 hours. The service life of LED lamps and lanterns does not stop at the point of light, but is based on the period of maintaining the luminous flux at 70% or more. The LED bulb lamp has been tested by the authority of the domestic authorities in the temperature environment of nearly 60 degrees C, and has created a record for 2500 hours to keep the luminous flux attenuation better than 2%. It depends on the selection of high quality import chip and excellent heat dissipation effect. Chip attenuation and long service life, long service life, high price. Japanese and American chips are more expensive, and the prices of Taiwan and domestic chips are lower than those of Japan and the United States.
