Light Emitting Diodes for Aerospace and Defense
Reliable and energy efficient solid state Light Emitting Diodes (LEDs) have evolved to the point where they are now an attractive choice for many applications that were once the domain of incandescent lamps. These include indication, backlighting push-buttons, panel overlays, liquid crystal displays (LCD’s), and most recently, general illumination.
Since there are no moving parts, LEDs are very reliable under shock and vibration conditions. And unlike incandescent lamps, there is no surge current when energized. They don’t have a filament that will burn out, and they don’t get especially hot when used with proper thermal management. They are also energy efficient and have a very long operating life.
