Starting from September 2015, production line number 5555, Boeing began to use the new LTRTL system in the 737NG fleet, that is, the new LED landing lights/taxi lights/runway departure lights.
Now, this system has been in use for 4 years and should not be new to everyone. However, it has recently been discovered that many people do not know this system very well.
Basic principles of system
LTRTL：Landing, Taxi, and Runway Turn off Light
LTRTL system uses light-emitting diode (LED) as light source, replacing the existing halogen lamp system.
The system combines five devices into two, reducing weight and energy consumption and reducing resistance. In addition, LED lamps to generate less heat than halogen lamps, thus prolonging the service life and improving the reliability of the system, thus reducing the operating and maintenance costs of airlines.
For example.
Old landing lights and runway turning lights.
Old system: Some aircraft taxi lights are ON/OFF and have no automatic position.
LTRTL system: LED landing light/taxi light integrated, retractable landing light canceled. New LED Runway Off Lamp.
LTRTL System: Removed retractable landing lights and switches.
Traditional halogen taxi lights and runway break-off lights can also be replaced by LED lights.
So LED is not less used in airplanes than cars.
Whether on planes or in cars, it shows a trend: the future is the era of LED, which is a trend. In the future, LED headlamps will continue to develop in the direction of high brightness, low energy consumption, and high response.
The LED lamp not only has the function of lighting but also can be used as a signal output port to timely indicate the status and needs of vehicles and drivers, which is the exploration direction of LED lamps in the future. Therefore, LED lamps are favored by more car owners.
In the future, lights will develop towards intelligence, digitalization, and personalization. From the light source, lights will gradually penetrate from halogen and xenon to LED and laser. The update of technical means will have a great impact on the whole light industry.
