The life of LED corn lamp beads is generally 3-5 years, and the theoretical life of LED lamps is 100,000 hours. According to the theoretical life, it can be used for 11 years.
But this is the highest value in the ideal state, which is impossible to achieve in normal use. The service life of led is also related to current, brightness, material and so on.
Its lifespan is similar to that of cask stock, not determined by the longest-lived components, but by the shortest-lived time inside.
Life of led corn lamp beads:
Generally speaking, it can be used for more than 50,000 hours, and some manufacturers can advertise that the LED can operate for about 100,000 hours.
The main problem with this is that LEDs don’t simply work, and their rated lifespan cannot be measured by traditional light fixtures.
In fact, no one is sitting around waiting for it to stop working while testing the service life. However, there are other ways to calculate the lifespan of an LED light.
LED light decay is related to its junction temperature. The so-called junction temperature means that the higher the semiconductor PN junction temperature, the earlier the light decay, that is, the shorter the life span.
If the junction temperature is 105 degrees, the lifespan is only more than 20,000 hours when the brightness is reduced to 70%, and 20,000 hours at 95 degrees, and the junction temperature is reduced to 75 degrees, the life is 50,000 hours, and the life can be extended to 90,000 hours at 65 degrees.
Therefore, the key to prolonging the life is to reduce the junction temperature. LED it doesn’t stop outright, but gradually degrades over time.
The prediction shows that after 50,000 hours of continuous operation of high-quality led corn lights, the initial lamp brightness can maintain more than 80%.
It is assumed that the LED has reached its rated lifetime. In fact, it may still be glowing, but in very low light. In order to prolong its light it is necessary to reduce or completely dissipate the heat generated by the LED chip for its lifetime.
