LED Junction Temperature
is the temperature at the light emission point at the
heart of an LED device (called the ‘p-n junction’). This
is a critically important parameter for high reliability
LED applications because both LED lifetime and LED light
output are directly proportional to junction temperature.
By controlling LED junction temperature through a variety
of thermal management techniques, optimally efficient
LED lighting designs with very long service lives can
be realised.
We can conduct empirical LED junction temperature measurement
in our custom built LED laboratory usually within a very
short timescale. From such measurements we can confirm
actual LED operating efficiency and projected lifetime
in whatever environmental conditions you specify.
In contrast to expensive and time consuming computer based
modelling, practical LED junction temperature measurement
provides a very fast and very reliable way to verify the
performance of LED lighting designs. Consequently we are
delighted to offer LED junction temperature measurement
as part of our LED design support capability. |
