If you can use a LED light source for a long period of time, you will get to experience great economic benefit as well as green footprint. In accordance with the system design, negligible decrease in luminous flux eventually is expected. When life span degradation is extremely slow, the system tends to stay in good conditions without maintenance for a longer period.
LEDs are superior as compared to other sources of lights in a number of applications. In order to maintain the system in good conditions; it is important that you take into consideration the following factors.
5 major factors that influence longevity of LED lights
Efficiency
LED lights and LED modules are manufactured and driven within a particular current range. You should provide the LED in accordance to its features with appropriate current range from 350mA to 500mA. A number of systems drive the LED at the higher end of the current range.
Acid conditions
LEDs that are operated under diverse conditions such as coastal weather in the midst of a high salt content, in plants that produce chemicals or indoor swimming pools are susceptible to acid conditions. LEDs are made for such areas but only packed cautiously into a closed housing with a high IP rating.
Heat
Heat affects the luminous flux and life cycle of LEDs. Heat sinks avert the system from becoming too hot. Heated systems means that the permitted ambient temperature of the LED light is surpassed. The longevity of the LED depends upon how cool the ambient temperature is.
Mechanical effects
Mechanical stress during manufacturing, packaging, transportation, or simply handling the LEDs impacts the lifespan of an LED light and sometimes even destroys it completely. Watch out for electrostatic discharge (ESD), which causes an extremely short but elevated current pulse. The LED and the LED driver may be damaged by ESDs.
Humidity
Depending upon the damp surroundings, LEDs are quite resistant to humidity. However, the electronic devices, metal parts and connections tend to get damaged really quickly. They begin to rust and therefore, it is better to guard the LED system cautiously against humidity。
