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 herein is a LED PAPI having an array of light emitting diodes (LEDs), the array of LEDs comprising a first set of LEDs emitting a first color and a second set of LEDs emitting a second color. Light from the array of LEDs passes through a pair of apertures separated by a precision ground blade. The precision ground blade has a first edge that is closest to the array of LEDs and a second edge opposite the first edge. The first and second edges have different thicknesses. After passing through the apertures, the light passes through a first lens and a second lens.
