Back of the envelope calculations are useful at the beginning of a project for estimating LED type and count. Techniques for calculating optical quantities and estimating LED count will be presented for some typical applications.
This video informs viewers about using commonly-available software to model their proposed LED system and its effects on the lighting environment.
One of the most critical design parameters in an LED illumination system is the system’s ability to draw heat away from the LED package. High operating temperatures at the LED junction adversely affect the performance of the LED, resulting in color shifts and decreased light output and lifetime for the LED package. Therefore, monitoring the LED function temperature is paramount for the overall system performance.
