what factors will make the back light source life greatly reduced?

  Many venues use led as a product, which is often used for backlight illumination. However, due to the limitations of using led, led is gradually being replaced by backlighting, a product that is often used to illuminate the background so that promotional graphics can show a better visual, which is the reason why many people choose backlighting. So, what factors will make the back light source life greatly reduced?

First, long-term exposure to the sun or rain

Many products can not be regularly exposed to the sun, otherwise the exterior shell will become more fragile, often drizzle will make the internal parts of the aging rust faster. The back light source is often affixed to the sea treasure in the outdoor, so the location often irradiate the sun will let the back light source life shortened, rain or sprinkle to the water is also the same will let the back light source effect become weak.

Second, a long time to use

There is a limit to the amount of time people can work in a day, after that limit they will feel physically exhausted, and the backlight is also used for a long time, the temperature of the surface will rise and the internal parts will work under load, which will greatly reduce the cycle time of its use. It should be opened when needed and closed briefly for a rest when not needed.

Third, the current used is too high

Under normal circumstances the voltage used at home is fixed, only the factory may be different, the use of the product is also within the prescribed current range. But if the backlight used is their own secondary transformation products, then it is possible to change the range of its current, so for the backlight is burning life, the use of life will be shortened accordingly.

Under normal circumstances the life of a good backlight is quite long and can last for several years with reasonable use. However, if you do not pay attention to protection in the process of use, the life span will be shortened, and failure to switch off the power supply for a long time will also put the backlight under load. For the use of backlighting considerations or should be more understanding of the correct to use in order to improve the life.
