Patent ID: 8083384

Claim:
An aircraft light source, comprising: a first substrate having a first side and a second side; an array of electromagnetic energy emitters being connected in series, the array comprising at least a first and a second electromagnetic energy emitters, the first and second electromagnetic energy emitters comprising a cathode and an anode, wherein the anode of the first electromagnetic energy emitter is configured to couple to an aircraft electrical power system, wherein the cathode of the first electromagnetic energy emitter is configured to couple to the anode of the second electromagnetic energy emitter, wherein each of the at least first and second electromagnetic energy emitters have a specified forward bias voltage drop, wherein a sum of the forward bias voltage drops reduces a current drawn by the array to produce a specific uniform predetermined spectral output and a thermal signature substantially similar to an incandescent lamp in an aircraft illumination system, wherein the light source is a direct drop-in replacement for the incandescent lamp, and wherein the light source requires substantially no thermal transfer, the electromagnetic energy emitters configured to radiate electromagnetic energy at one or more than one predetermined wavelengths, the second side of the first substrate configure to connect to a second substrate; a second substrate connected to the first substrate, the second substrate comprising a first side, a second side, a first end, a second end, the first and second sides are configured to receive one or more electrical components, the first end is configured to electrically couple to the array of electromagnetic energy emitters and the second end is configured to electrically couple to an aircraft electrical power system; and a housing having a cylindrical portion and a base portion, the cylindrical portion having a first end configured to couple to a lens and a second end configured to couple to an electric socket suitable for the incandescent lamp in the aircraft illumination system, the cylindrical portion defining an opening to receive the array of electromagnetic energy emitters and the first and second substrates therein, the base being adapted and configured to electrically couple to an electric socket suitable for the incandescent lamp in the aircraft illumination system.
