What is most important for LED light's lifespan ?
The most important things for LED light's lifespan is temperature acturely. The temperature more higher, the lfe span more shorter. And the led light bulb must be lowwer than 85 degrees
Most manufacturers now publicity is 60,000 hours of LED lamp life, the whole lamp life is typically 40,000 hours. Practical application is subject to many factors, not reach the theoretical value. With technology constantly led advances, declining costs and continuously improve the energy saving performance, LED display is gradually from the initial stage toward the stage lighting applications in depth, both in the international market or domestic market, LED lighting has entered commercial even home lighting market sector, showing a good momentum of development. Its long life, high efficiency, energy saving features have been more and more attention and research, LED lights and other products have been more and more widely used.
But LED lights also have some defects, single LED lamp and LED lamp composed of luminaires been tested in terms of aging or have some differences. This distinction can be analyzed from LED lights use environment and a variety of other parameters, how to effectively extend the service life of LED lights is a problem worth talking about.
First, the quality of selection LED lamp is a very important factor. The quality of different packaging processes of the product will have a considerable impact. Package out of ordinary plastic bottom LED lights than the A class of low attenuation glue package out of LED lights in the same aging environment, reduce light decline of 76%. So, choose a good package fabrication of LED lights will greatly extend its life.
Secondly, LED lamp beads at work, a single lamp beads heat will be relatively small, the stent temperature does not exceed 45 degrees, LED lamp life at this time would be ideal, but when the LED light group composition, the corresponding temperature is will rise, LED lighting is not conducive to long-term use.
There are two ways to solve, is the first choice of lamp beads lamp apart from the bigger group, the best distance of more than 25MM, the second LED is at work, it is best next to a small fan to help it dissipate heat, it will also extend its service life.
In short, it is afraid of the heat, the higher the temperature, the shorter the life of the LED, the lower the temperature, the longer LED life. LED is of course ideal operating temperature between minus 5 to zero. But this is basically impossible. Therefore, consumers in the choice of LED lamps when we must understand its performance, and to reasonable protection when in use, so as to play its best results, let you add luster.
So the heat sink is very important for LEDs.
