Methods and systems for easily integrating a light-emitting diode (LED) light assembly with an existing xenon power supply. An exemplary system includes a xenon power supply that includes an energy storage device and a device that commands the energy storage device to discharge the stored energy and transmit a trigger signal after a predefined amount of time since at least one of a previous discharge or a beginning of initial charge of the energy storage device. The LED light assembly includes one or more LEDs and a current regulator that receives the discharge from the storage device and regulates current to the LEDs based on LED requirements. The LED light assembly also includes a processing device that receives the trigger signal, resets and begins a timer upon reception of the trigger signal and deactivates the current regulator when the timer has reached predefined threshold.

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.

A rotationally symmetrical anti-collision light () for an aircraft utilizing light-emitting diodes (LEDs) is mounted to the fuselage of an aircraft. The LEDs (') may be configured in one or more concentric rings. The anti-collision light includes a reflector (&#x2032;) configured to redirect the light emitted by at least one of the rings, so that the light pattern satisfies predetermined specifications.

Flashing lights powered by a common wild frequency power source () are synchronized with respect to flash rate and duration. Each lighthead includes a power supply device (), which includes a timing signal generator () and a synchronization device (). The timing signal generator () includes a precision clock (), which generates a timing signal to regulate the flashing operation of the corresponding light. The synchronization device recurrently causes the timing signal to be reset in accordance with the wild frequency power source signal. By recurrently resetting the timing signal of each light according to a common wild frequency source, the flashing of the lights can be synchronized without transferring synchronization signals between the lights.

A system and method for implementing an LED-based luminaire () incorporates one or more color channels (-). The luminaire includes a controller () that uses optical sensing and feedback to control LEDs (A) in each channel to deliver a consistent intensity and/or color output. The optical feedback loop may provide measured intensity and/or color of the luminaire's output to the luminaire controller. The controller may then adjust the current, pulse width modulation (PWM) duty cycle, or both, which are delivered to discrete color channels of the luminaire to obtain the desired intensity and/or color.

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