Abstract

The invention provides a rear navigation lamp with a lower hemisphere plated with an infrared filtering film. The rear navigation lamp comprises a first light source, a second light source and a lampshade (3). Light emitted by the first light source is visible to human eyes, and light emitted by the second light source is invisible to human eyes; the rear navigation lamp is fixed on an aircraft body and is vertically arranged, and the first light source and the second light source are fixedly arranged in the rear navigation lamp and face the tail of the aircraft; the lampshade (3) covers the first light source and the second light source, the lower half portion of the lampshade (3) is plated with a filter membrane, the light transmittance of the filter membrane to the first light source is larger than the first light transmittance, and the light transmittance of the filter membrane to the second light source is not larger than the second light transmittance. And the filter membrane is used for preventing light rays emitted by the second light source from radiating towards the lower part of the airplane.

Description

technical field [0001] The invention belongs to the technical field of aviation accessories, in particular to a rear navigation light coated with an infrared filter film on the lower hemisphere. Background technique [0002] The rear navigation light is an important external lighting device of the aircraft. It is installed at the tail of the fuselage to display the maximum shape of the tail of the aircraft, provide its own position and direction of movement to other aircraft, and also help pilots visually identify other aircraft when flying at night. The heading of the aircraft, so as to grasp the situation of the surrounding airspace, and make timely predictions and corresponding measures. [0003] Most current aircraft use white LED lights as the light source for the rear navigation lights. However, there are some situations where only one's own side is required to be visible, and the existing rear navigation lights cannot be realized. Contents of the invention [0004...
