Factors that Affect LED Lifespan

- Aug 19, 2019-

Over even short periods of time, too much heat can erode the capabilities of that circuitry and the quality of the light it produces. LED manufacturers generally control this factor with active or passive heat dissipation technology. Active mechanisms like cooling fans increase an LED lighting system’s electrical load and are prone to mechanical failures. Accordingly, passive cooling fins are preferred for thermal management.

The engineers at Cary, a domestic manufacturer of LED lighting systems, have developed a proprietary passive thermal management system that incorporates multiple double-folded aluminum fins directly into the LED fixture. SpecGrade LED’s proprietary technology configures these fins in a consolidated design to allow maximum airflow with ideal thermal connectivity to the base semiconductor circuitry. That technology is a key factor in the longer LED lifespan of a SpecGrade LED fixture.        

LED lifespan can also be affected by the environment in which the fixture is installed. Environments that have high humidity levels or that expose LED fixtures to corrosive chemicals can degrade the fixtures and harm the LED circuitry. We have designed and engineered LED lighting technology specifically for these types of high-stress hazardous environments. These fixtures separate circuitry from humidity and airborne chemicals with casings that resist corrosion.

The control technology for an LED lighting system will also affect its lifespan. If an LED lighting system experiences electrical loads that exceed the system’s ratings, that excess load will rapidly reduce LED lifespan. As much as it is important to select the right LED lighting system for the environment in which the system will be installed, it is important to use the right control technology that limits electrical load to match the system’s ratings.
