In accordance with an example embodiment, there is disclosed herein a LED PAPI () with condensation protection. The condensation protection may suitably comprise passive components, such as gaskets and seals () and a desiccant (), and/or active components, such as a defroster () and/or a heater ().

LED PAPI with condensation protection

Described in an example embodiment is an airfield light where the optical system can be easily removed, e.g., no tools. This allows maintenance of the optical system to be performed elsewhere, reducing the amount of time that airfield maintenance crews have to be spend on the field.

Airfield luminaire having optical removability

A runway, taxiway or obstruction fighting system having at least one side emitting LED mounted on a base. A cover is optically coupled to the side emitting LED to direct fight at a desired angle from a horizontal plane extending from the base. The cover is manufactured to have the highest transmissivity when used with a monochromatic LED light source. The color of the material is tuned to the wavelength of the LED light source to obtain the maximum light output. A heater circuit is included in the lighting system wired in series with the side emitting LED. A constant current source is employed to supply power to the side emitting LED and heater circuit so that operation of the heater circuit does not affect the intensity of the light from the side emitting LED.

Airfield edge-light utilizing a side-emitting light source

An airfield guidance sign. The sign 100 (of FIG.) includes a case (), a multi-element light source () attached to the case () for providing light interior to the case (), a light dispersion subsystem of the case for dispersing the light from the light source () substantially uniformly throughout the interior of the case (); and a side panel () forming a side of the case () for displaying information.
