The cockpit of an aircraft is an amazingly complex space. While pilots are trained in the operation of the aircraft, pilot light systems are also in place for quick and easy visual confirmation of the status of different systems.
In the past, many of these pilot working lights, indicator lights, signals and even general interior lighting were all done with the use of incandescent bulbs. While they are effective and can get the job done, they also have more than a few significant issues.
By switching from old and outdated types of lamps to LED pilot light systems, airlines can save money, lower costly replacements and also help to ensure all indicators and lights are working.
Vibration Resistance
For airlines and the aerospace industry, vibration can be a very critical factor with many of the traditional types of incandescent bulbs. This is because of the use of a filament to create the light instead of the light emitting diode. The filament is very sensitive to vibration and shock. Damage to the filament is common under these conditions.
With use in airplanes, the constant vibrations and shock during landing and takeoff can increase the risk of damage to the filaments. This leads to the continual need for replacement or having to operate the flight without the lights, leading to safety issues.
Lower Energy Drain
LED lighting requires much less energy. While they are not a substantial drain on the system, conserving energy is always important. Lower power consumption helps to preserve additional power for other sources used during the flight.
At the same time as they decrease the overall power use by the lighting system, the LED lights provide constant light output. This means no fading and flickering of the lights as seen with the traditional lighting systems.
Longer Life
When it comes to pilot light systems, longer life for each individual bulb is important. Not only will this help to decrease maintenance and replacement, but it also provides a better working environment for the pilot and crew.
The typical life of an LED bulb in a control panel or used as a pilot work light or for interior cabin lighting is about 10 years. This is substantially longer than incandescent bulbs, which may only last one to two years. While initially slightly more expensive, their extended life, dependability and decreased replacement costs quickly make up the difference.
