id you hear that? The Earth shifts on its axis? Perhaps not.
This movement in aircraft lighting wasn't the sort of
tectonic shift that registers on the Richter scale or shows up
in a U.S. Geological Survey earthquake report.
But it's something of a tectonic movement nonetheless,
o
one
ne seen accelerating well beyond the old glacial pace that marked
the initial shift to modern light-emitting diode technology for our
illumination needs - particularly in aviation.
And good timing, too. As aircraft panels evolved into glass from
mechanical, demands grew on electrical-generating sources; throw
in the need for standby power, and moving away from incandescent
and halogen sources of illumination helps reverse the growth in
generating power.
In fact, the shift in illumination source follows an early move to LED
technology to light most of today's glass-cockpit displays - from cathode
ray tubes to liquid crystal to light-projected and on to an increasingly
LED world for lights, displays, engine instruments - the works.
Arguably, shifting to today's LEDs for aircraft lighting stands
