Abstract

A Light Emitting Diode (LED) light for an aircraft includes a hollow cylindrical body, a plurality of LEDs mounted in the hollow body, and at least one reflector to receive light beams emitted by the LEDs and configured to direct the light beams in a lighting direction of the LED light. The LEDs are mounted on a cylindrical support and disposed radially in the cylindrical body, and the cylindrical support has a polygonal contour.

First claim

What is claimed is:

1 . A Light Emitting Diode (LED) light for an aircraft, comprising:
a hollow cylindrical body: a plurality of LEDs mounted in the hollow body; and at least one reflector to receive light beams emitted by the LEDs and configured to direct the light beams in a lighting direction of the LED light, wherein the LEDs are mounted on a cylindrical support and disposed radially in the cylindrical body, the cylindrical support having a polygonal contour.

2 . The LED light according to claim 1 , wherein each side of the cylindrical support having the polygonal contour comprises a plurality of LEDs.

3 . The LED light according to claim 1 , wherein:
the support comprises an annular support; and at least one piece of equipment to execute an auxiliary function is mounted at a center of the annular support.

4 . The LED light according to claim 3 , wherein the piece of equipment is selected from the group consisting of a camera, a radar, and a sensor.

5 . The LED light according to claim 3 , wherein the piece of equipment is covered by a glass that is transparent to light.

6 . The LED light according to claim 5 , wherein the glass comprises a de-icer.

7 . The LED light according to claim 1 , wherein the support includes a front face comprising a radiator for dissipating thermal energy, and the radiator is annular or disk shaped.

8 . The LED light according to claim 1 , wherein the diodes are mounted on at least one printed circuit board fixed on the support.

9 . The LED light according to claim 1 , further comprising an electronic card for powering the diodes mounted in the body.

10 . The LED light according to claim 1 , further comprising an annular glass sealably covering the diodes and the reflector.

11 . The LED light according to claim 1 , wherein the body includes a rear face comprising a radiator for dissipation of thermal energy.

12 . The LED light according to claim 1 , further comprising a set of juxtaposed reflector elements of revolution having a typically parabolic generatrix.

13 . The LED light according to claim 12 , wherein each diode is associated with a reflecting element.

14 . The LED light according to claim 12 , further comprising reflector elements inclinedly mounted with respect to the lighting direction of the LED light.

15 . The LED light according to claim 14 , wherein the reflector elements comprise injection molded plastic covered with a layer of light-reflecting aluminum.
