A method for manufacturing a panel includes forming a path segment on a surface of a substrate from a photoluminescent material. The method further includes overlaying the path segment with an overlay material. The overlay material is configured to render the path segment substantially invisible under an ambient photopic condition and render the path segment visible under an ambient mesopic or scotopic condition.

An air duct system comprising an air duct having a main body, a visible light source, an emitter configured to emit radio frequency waves, and one or more antennas. The main body of the air duct defines a passageway having a reflective inner surface. The visible light source is configured to generate visible light. The visible light source directs the visible light along the reflective inner surface of the air duct. The emitter directs the radio frequency waves along the reflective inner surface of the air duct. The one or more antennas are each connected to a corresponding power harvesting circuit, where the radio frequency waves are received by the one or more antennas and are converted into electrical power by the corresponding power harvesting circuit.

A light assembly may comprise a heatsink, a plurality of light emitting diodes, and a lens. The heatsink may include a first surface and a second surface opposite the first surface. The second surface may define an airflow path extending from a first end of the heatsink to a second end of the heatsink. The plurality of light emitting diodes may be coupled to the first surface of the heatsink. The lens may be located over the plurality of light emitting diodes and may contact the heatsink.

A runway-embedded flash lighting device, includes a body configured to be embedded in a runway; a ceiling member including a flash emission window and disposed in an upper opening of the body and configured to be exposed to a runway surface when the body is embedded in the runway; a light guide member disposed in the flash emission window; an LED flash light source disposed inside the body and configured to emit a flash toward the light guide member; and a heat conducting member, wherein the light guide is configured to allow the flash emitted from the LED flash light source to be emitted from the flash emission window, the heat conducting member is disposed inside the body and includes a first part in contact with the LED flash light source, and a second part in contact with the ceiling member.

A lighting unit may include a first light-emitting diode (“LED”), a second LED, and a third LED. The first LED may be configured to emit first electromagnetic radiation having a first wavelength of between about 600 nanometers (“nm”) and about 740 nm, the second LED may be configured to emit second electromagnetic radiation having a second wavelength of between about 500 nm and about 565 nm, and the third LED may be configured to emit third electromagnetic radiation having a third wavelength between about 315 nm and about 430 nm. Thus, the third electromagnetic radiation may be disinfecting UV-A radiation that is incorporated into a lighting unit that produces visible light.

A non-pyrotechnic aerial display apparatus may include a head portion and a wing portion. The head portion may include a front portion, a rear portion, and a plurality of channels extending from the front portion toward the rear portion. The wing portion may extend rearward from the head portion. The wing portion may include a top surface, a bottom surface, a leading edge, a trailing edge, a rear edge extending from the leading edge to the trailing edge, and an airfoil extending along the leading edge. The wing portion may include a counterweight. The apparatus may include one or more forward-facing lights. The apparatus may include one or more rearward-facing lights. Other examples may be described and claimed.

An installation powers and controls a plurality of signaling lights arranged in series, each having at least one light source. The installation includes a unit with a primary power supply situated upstream for remotely programming or managing operation of the installation; a primary series circuit with a transformer for each signaling light; a control module for each signaling light; a secondary power supply circuit for powering the control modules, independent of the primary circuit; a first optical cable for bi-directionally connecting a first upstream module to the programming or managing unit; and a second optical cable for bi-directionally connecting a last downstream control module to the programming/management unit, with each control module being connected in series to an adjacent upstream module and to an adjacent downstream module by means of a respective bi-directional optical connection.

A cover for an exterior aircraft light includes a lens cover structure, attachable to an exterior aircraft light housing and configured to close the exterior aircraft light housing, wherein the lens cover structure has an inside and an outside and is at least partially made of transparent material; and a wear indicator, attached to the inside of the lens cover structure, the wear indicator having a contrasted pattern visible from the outside of the lens cover structure through the transparent material.
