Over the entire
commercial range of LEDs – from
near-ultraviolet (360 nm) to nearinfrared
(950 nm) – there is no
consistency in defining specifications.
This makes it challenging
for users to compare the relative
efficiencies of LEDs in the visible
region to LEDs outside it.
Particularly in the visible region, it
is difficult for users to specify
LEDs in a manner that correlates
well to the system application.
This article provides an overview
of the important LED performance
parameters, enabling users to select the product that
best meets the needs of their particular application.
