Abstract
A light assembly includes a housing, a light emitting diode (LED), and a hemispherical dome. The housing has a lens mounted thereon. The light LED is mounted within the housing and operable to emit light within a predetermined range of wavelengths and at an emission intensity toward the lens. The hemispherical dome mounted is within the housing between the LED and the lens. The hemispherical dome comprises a material that attenuates the emission intensity by a predetermined magnitude, and has an aperture formed therein and through which a portion of the light emitted from the LED may pass unattenuated.

A light assembly, comprising:
- a housing having a lens mounted thereon;
- a light emitting diode (LED) mounted within the housing, the LED operable to emit light within a predetermined range of wavelengths and at an emission intensity toward the lens;
- and
- a hemispherical dome mounted within the housing between the LED and the lens, the hemispherical dome comprising a material that attenuates the emission intensity by a predetermined magnitude, the hemispherical dome having an aperture formed therein and through which a portion of the light emitted from the LED may pass unattenuated.
An aircraft position light assembly, comprising:
- a housing having a lens mounted thereon;
- an infrared light emitting diode (IRLED) mounted within the housing, the IRLED operable to emit IR light at an emission intensity toward the lens;
- a plurality of non-IR LEDs mounted within the housing and spaced apart from the IR LED, each of non-IR LEDs operable to emit visible light in a direction away from the lens;
- and
- a hemispherical dome mounted within the housing between the IRLED and the lens, the hemispherical dome comprising a material that attenuates the emission intensity by a predetermined magnitude, the hemispherical dome having an apex and an axis of symmetry that extends through the apex, and further having an aperture formed therein and through which a portion of the IR light emitted from the IRLED may pass unattenuated, the aperture disposed at a predetermined angle relative to the axis of symmetry.
