Abstract: A light-emitting diode (“LED”) lighting unit includes an operational, a sense resistor electrically connected to the input of the operational amplifier, a first field effect transistor (“FET”) whose gate is electrically connected to the output such that the input voltage at the gate of the first FET rises and falls with the output voltage, a second FET whose gate is electrically connected to the output such that the input voltage at the gate of the second FET rises and falls with the output voltage, and a string of LED lights connected such that when the voltage across the string drops below a level to operate, the voltage across a sense resistor drops, causing the operational amplifier to increase its output until the input voltage at the gate of the second FET increases allowing one bank of LED lights to operate.

Abstract: An LED lighting assembly includes, according to various implementations, mechanisms for protecting the LED lights from voltage or current surges, including hardware that absorbs the strike voltage and hardware that provides a bypass path. The provision of a bypass path in the event of the failure of one or LED lights in an LED string allows the string to be, in effect, “turned off” in order to protect the remaining LED lights, thereby allowing the healthy LED lights to stay lit.

Abstract: An LED lighting assembly onboard an aircraft includes at least one light emitting diode (LED) unit and a controller. The LED unit includes any number of primary LEDs and at least two white LEDs. The controller is configured to supply respective driving signals to each of the LEDs, the respective driving signals individually controlling relative intensity outputs of the respective LEDs. The controller is further configured to display a desired color point by continuously driving the white LEDs while not driving at least one of the other LEDs.

Abstract: Described is an LED replacement bulb having the same physical shape and appearance as a fluorescent bulb, but having the superior illumination characteristics of LED lights (e.g., the ability to dim, the absence of flicker) and the ability to switch (with or without transition) from a first color to a second color while the LED lighting assembly undergoes a dimming or brightening procedure. Furthermore, because the bulb uses the output of the light fixture (e.g., the output of the ballast of a fluorescent light fixture) as the cue for whether to change colors, no retrofitting of the lighting system is required (as might be the case if more modern, network-addressable light units were required).

Abstract: The present disclosure is generally directed to an aircraft cabin LED lighting system and lighting assembly, in which each LED light is paired with and controlled by a separate microcontroller, which is individually addressable. In various embodiments, a lighting control device (e.g., a control panel for flight attendants) transmits pixel data to various lighting assemblies around the cabin. These lighting assemblies include the microcontroller-LED light pairs. Each LED light is multicolor and includes multiple LEDs (e.g., one for each color). The pixel data defines a color scheme and/or animation sequence. Each pixel maps to one of the microcontroller-LED pairs. The microcontroller controls the intensity of each LED of the LED light according to the pixel data it receives.
