Methods and systems are provided for autonomously operating a retractable lighting arrangement. One method involves obtaining a current speed of the vehicle when the lighting arrangement is in an extended state, and when the current speed is greater than a threshold when the lighting arrangement is in the extended state, verifying one or more illumination elements associated with the lighting arrangement are in a deactivated state and thereafter automatically signaling an actuation arrangement associated with the lighting arrangement to transition the lighting arrangement from the extended state to a retracted state.

Retractable lighting systems and autoretraction methods

Provided systems and methods for an aircraft lighting system (ALS) include a centralized blue generator that supplies blue light to a plurality (N) of passive light-heads distributed at various locations on the aircraft. A load profile for use of the N passive light-heads during all flight phases and operational phases is developed and uploaded into the system. Each of the passive light-heads is operationally coupled to the blue light generator via a respective light transmission element that is gated with a respective one of N light switches. A light generating control unit (LGCU) is coupled to the blue light generator, and controls the generation and actuation of blue light, in addition to controlling light switch positions, as a function of navigation data and the load profile. Each of the N passive light-heads comprises a respective light conversion element to convert the blue light into red, green, or white light.

Architecture and method for aircraft lighting system using a centralized blue light source and a plurality of distributed passive light-heads

Systems and methods for allowing replacement of updated light heads with different design parameters to become independent of the remote power supply. An exemplary light system includes a light head remote from a power supply component. The light head includes one or more light-emitting diodes (LEDs) or other light emitting devices, a memory that stores configuration information and a communication component. The power supply component includes a power converter, a memory, and a controller. The power converter outputs an electrical signal for driving the one or more LEDs. The memory stores light head configuration information. The controller receives configuration information from the communication component via the data bus, generates and sends instructions, based on at least one of the configuration information stored in the power supply component memory or the configuration information received from the light head, to the power converter.

Methods and systems for minimizing light source power supply compatibility issues

A secure light emitting diodes (LEDs) power system controls power to a plurality of LEDs residing in a secure LED fixture coupled to a secure LED fixture mounting. An exemplary embodiment provides power to the plurality of LEDs and senses the power provided to the LEDs. In response to sensing the power, an authorization signal is communicated from a security sensor residing in the secure LED fixture. Power to the plurality of LEDs is maintained only in response to the communicated authorization signal.
