Problems solved by technology

However, the position sensor disclosed by Metz cannot adapt to different types of aircraft and reconfigure the operating range, so it is forced to adjust by trial and error
[0013] Need to limit inrush current, eliminate low reliability relays and switches associated with retractable landing lights

Embodiment Construction

[0022] figure 1 A retractable landing light 100 is shown. One base or fixture 102 is the frame and also easily secures the retractable landing light 100 to the aircraft. Transformer 104 converts electrical power from the aircraft to a level compatible with lights 112 . Controller 106 monitors the position of lamp head 108 . The controller 106 also provides "soft start" solid state power switches for the motor 110, brake 111 and light 112 to extend the life of the motor 110, brake 111 and light 112 and reduce electromagnetic emissions. Additionally, the controller 106 may provide protection during fault conditions, such as overcurrent or overtemperature conditions, stalling of the motor 110 and obstruction of the lamp head 108 . Furthermore, the controller 106 is easy to simplify changing the given value of the lamp head 108, and can also add new functions. The controller 106 may optionally include means for causing the lights 112 to flash on and off on a regular basis, or ...

Abstract

An electronically controlled retractable landing light ( 100 ) for use with aircraft. A controller ( 106 ) compares the commanded position of a lighthead ( 108 ) by means of a contactless absolute position sensor ( 212 ). Operation of a brake ( 111 ), motor ( 110 ), and lamp ( 112 ) is controlled by a control unit ( 210 ). Electrical power to the brake ( 111 ), motor ( 110 ), and lamp ( 112 ) is slowly applied and removed to reduce electromagnetic emissions and extend the service life of a power stage ( 208 ), brake ( 111 ), motor ( 110 ), and lamp ( 112 ). The lighthead ( 108 ) may be manually stowed in the event of a fault.

Description

[0001] related reference [0002] This application is related to a co-pending application entitled "High Efficiency Solid State Switching and Control System for Retractable Aircraft Landing Lights" by D. Melvin and S. Mubaslat (Attorney Docket No. H0002974). [0003] This application claims the benefit of US Provisional Application No. 60 / 339,635, filed December 12, 2000 entitled "Electronically Controlled Retractable Landing Light". technical field [0004] The invention relates to a retractable landing light for an aircraft. More particularly, the present invention is directed to an aircraft retractable landing light with electronic position control and switch, with manual head retraction capability. Background technique [0005] Landing lights are mounted on the aircraft to illuminate the area in front of the aircraft when performing night operations on taxiways and runways. The "retractable landing lights" are remote-controlled, and when not in use, the hinged lights c...
