The Lifetime of LED High Bay

In the general instruction,  led high bay   is able to use over 50,000 hours. Some manufactories even declare that LED High Bay could operate about 100,000 hours. The main problem is that LED is not just to stop working. Its rated lifetime could not be calculated by the judging methods of traditional light. In fact, when testing the lifetime of LED light, no one stays there and wait for its stopping working. However, there are some other methods to reckon the lifetime.

The reason why LED is durable is that it won’t occur to the problem of filament fusing. LED is not to cease operation directly, but with the time passing by, it degenerates little by little. It’s said that high quality LED could maintain more than 60% luminance of original light after persistently running 50,000 hours. LED is presumed to reach the rated lifetime but actually it may be still keep shining in a weak light. In order to prolong the lifetime of LED, it’s necessary to decrease or totally dispel the thermal energy that LED chip produces because it is the main reason that causes LED stop running.

It’s estimated that LED is able to use hundreds and thousands hours but it can’t be guaranteed that LED light also has the long lifetime. It’s easy to damage LED with some wrong operation and process. For example, if the supplied current is higher than rated current that manufactories provide, LED looks much brighter, but the persistent thermal energy would shorten the lifetime of LED. Real LED expert must fully understand the feature of light emitting diode and professional technology of solid lighting, besides, enough creativity is also preferred.
