The LED general description, usually said you can use more than
50,000 hours, and some manufacturers claim that the LED can be 100,000
hours of operation. The main problem is in this regard that the LED is
not a simple no longer in operation only, its rated life can not be
calculated with the traditional lighting of the measure.
In fact,
when testing LED life, no one will stay beside waiting for it to stop
working. However, there are still other ways to measure the service life
of the LED.
LED Spotlight
is lasting, because it does not produce a filament fuse. LED will not
directly stop the operation, but as time goes by, it will gradually
degraded. Projections indicate that the high-quality LED after 50,000
hours of continuous operation, can maintain more than 60% of the initial
light levels. Assumed that the LED has reached its rated life, in fact,
it may still luminous, but the light is very weak Bale. In order to
extend the service life of the LED, it is necessary to reduce or
completely disperse the heat generated LED chip. The thermal energy is
the main reason of the operation of LED stops.
It is estimated
that the LED itself can be used thousands of hours, but this does not
guarantee that the LED products can also be used so long. Wrong
operations and processes can easily ruin “LED. For example, the supply
current is higher than the scale approved by the manufacturer,china led bulb
will be brighter, but sustained heat will shorten the service life of
the LED. True connoisseur of LED to the characteristics of the
light-emitting diodes, solid-state lighting, technical expertise and
engineering skills fully understand the need to have enough creativity
