Which five main factors will affect the span life of LED lights?

If you use a light source for a long time, you will get huge economic benefits and reduce your carbon footprint. Depending on the system design, luminous flux reduction is a normal process, but can be ignored. When the luminous flux is reduced very slowly, the system will remain in good condition without long maintenance.
Compared to other light sources in many applications, LEDs are undoubtedly superior. In order to keep the system in good condition, the following five factors need to be considered.
Effectiveness
LED lamps and LED modules are manufactured and driven in specific current ranges. LEDs with currents from 350mA to 500mA can be provided according to their characteristics. Many systems are driven in high value regions of this current range
Acidic condition
LEDs are also susceptible to some acidic conditions, such as in coastal areas with high salt content, in factories that use chemicals or manufactured products, or in indoor swimming pools. Although LEDs are also manufactured for these areas, they must be carefully packaged into a fully enclosed enclosure with a high degree of IP protection.
Heat
Heat affects the luminous flux and life cycle of the LED. The heat sink prevents the system from overheating. The heating of the system means that the allowable ambient temperature of the LED lamp is exceeded. The life of the LED depends on the ambient temperature around it.
Mechanical stress
When manufacturing, stacking or simply operating LEDs, mechanical stress can also affect the life of the LED lamp, and sometimes even completely destroy the LED lamp. Pay attention to electrostatic discharge (ESD) as this can cause short but high current pulses that can damage the LED and LED driver.
Humidity
The performance of the LED also depends on the humidity of the surrounding environment. Because in a humid environment, electronic equipment, metal parts, etc. are often quickly damaged and begin to rust, so try to keep the LED system from moisture.
