LIGHTING

摘要

LEDs are the most efficient light source available in today's market. Toxin-free, LEDs are green and can substantially outlast standard light sources. Although simple in stature, the complexity of LEDs and their functionalities should not be underestimated. The performance of an LED is greatly impacted by elevated temperatures and, if improperly managed, will impact the light output and rate of degradation. In other words, thermal management is crucial and greatly impacts the design of an LED lighting system. Another area of concern is the consistency in the LED chips. A fabricated 2-inch LED wafer can carry thousands of LED chips with vast color and intensity variations across a wafer. Ensuring tight "binning" reduces disparities among the chips selected and ultimately within an LED lighting system.
