LED LIFE EXPECTANCY FOR INTERNAL OR EXTERIOR ADVERTISING SCREENS

The approximate lifespan of a LED can range from 80,000 to about 120,000 h, it all depends on the LED manufacturer. 

This estimate can be reduced considerably in cases where the operating conditions are particularly damaging to the LED.

BRIGHTNESS LOSS IN LED SCREENS

Like any light element, LEDS suffer wear during their use. Although its wear is progressive and less evident than other conventional lighting systems, its wear and tear is constant, and it is something that must be taken into consideration when carrying out the repair or replacement of LED panels or modules.

RELATIONSHIP BETWEEN TEMPERATURE - LUMINOSITY AND LED LIFE EXPECTANCY

The first determining factor of the longer or shorter life expectancy of a LED is the operating temperature of the LED. The higher the temperature, the faster the life expectancy will be reduced. That is why it is important for the electronics that accompany the LED to be optimized and well designed to ensure that the LED works in optimal conditions. Forcing the LED with parameters that are higher than its nominal brightness range causes its working temperature to increase and thus reduces its useful life.

WHAT INFLUENCE DOES BRIGHTNESS HAVE IN THE LIFE EXPECTANCY OF A LED?

The second decisive factor in the useful life is the operating current. Usually most LEDs works at 350mA. A greater current causes the luminous efficiency to increase considerably, but at the cost of their useful life. This decreases the higher the value of the operating current. Therefore, to optimize the useful life of LEDs, it is essential to carry out a correct management of the brightness and not force electrical parameters to obtain a greater degree of brightness.
