Multi-beam light
An LED light system for an aircraft may comprise a first LED lamp having a first LED array. The first LED array may include at least a first LED and a second LED. A first optical element may be configured to direct light emitted from the first LED in a first beam centered around a first angle and to direct light emitted from the second LED in a second beam centered around a second angle. The LED light system may further comprise a second LED lamp having a second LED array. The second LED array may include at least a third LED and a fourth LED. A second optical element may be configured to direct light emitted from the third LED in a third beam centered around the first angle and to direct light emitted from the fourth LED in a fourth beam centered around the second angle.
1. A light emitting diode (LED) light system retrofitted for an aircraft having a preexisting mounting area, comprising:
an LED lamp sized and configured to fit within the preexisting mounting area of the aircraft, the LED lamp having multiple light emitting diodes (LEDs) that define an LED array, the LED array being configured such that beams centered around different angles are formed by light emitted from different LEDs in the LED array being directed by a single optical element, wherein the LED array comprises a first LED aligned with an axis of the single optical element, a second LED positioned above the first LED, and a third LED positioned above the second LED.
2. The LED light system of claim 1 , wherein the single optical element comprises at least one of a reflector or a lens.
3. The LED light system of claim 2 , wherein the first LED and the second LED are disposed in a fixed position relative to the at least one of the reflector or the lens.
4. The LED light system of claim 2 , wherein the LED lamp comprises a parabolic aluminized reflector (PAR) lamp having the diameter between 17.8 centimeters and 22.9 centimeters.
5. The LED light system of claim 1 , wherein the LED lamp has a diameter based on the preexisting mounting area.
6. The LED light system of claim 1 , wherein the LED lamp operates as a takeoff light for the aircraft and as a landing light for the aircraft.
7. A method of replacing a light system of an aircraft with a light emitting diode (LED) light system retrofitted for the aircraft, comprising:
defining a defined lamp diameter based on a preexisting mounting area of the light system; and
installing a first LED lamp having the defined lamp diameter in the preexisting mounting area, the first LED lamp having multiple light emitting diodes (LEDs) that define a first LED array, the first LED array being configured such that beams centered around different angles are formed by light emitted from different LEDs in the first LED array being directed by a first single optical element, wherein the first LED array comprises a first LED aligned with an axis of the first single optical element, a second LED positioned above the first LED, and a third LED positioned above the second LED.
8. The method of claim 7 , further comprising:
positioning the first LED relative to the first single optical element to direct light emitted from the first LED in a first beam centered around a first angle; and
positioning the second LED relative to the first single optical element to direct light emitted from the second LED in a second beam centered around a second angle.
9. The method of claim 8 , wherein the first angle is configured for a takeoff light for the aircraft, and wherein the second angle is configured for a landing light of the aircraft.
10. The method of claim 9 , wherein the third LED is positioned relative to the first single optical element to direct light emitted from the third LED in a third beam centered around a third angle.
11. The method of claim 7 , wherein the first LED lamp comprises a parabolic aluminized reflector (PAR) lamp, and wherein the defined lamp diameter is between 17.8 centimeters and 22.9 centimeters.
12. The method of claim 7 , further comprising installing a second LED lamp having the defined lamp diameter in the preexisting mounting area, the second LED lamp having multiple LEDs that define a second LED array, the second LED array being configured such that beams centered around different angles are formed by light emitted from different LEDs in the second LED array being directed by a second single optical element.
