Lighting element with a light emitting diode
View Patent ↗A lighting element has a light emitting diode that is installed in a light carrier. The lighting element has a light guide element that is optically coupled to the light emitting diode and the light guide element has a smaller light exit surface than the light emitting diode. With a plurality of such lighting elements it is possible to embody an effect lighting configuration for example in an aircraft cabin.
1. A lighting element, comprising:
a light emitting diode being releasably fixed in a light carrier and defining a closed space above said light emitting diode, said light emitting diode having a light-emitting surface;
a light guide element installed in the light carrier and optically coupled to said light emitting diode, said light guide element having a light exit surface being smaller than said light-emitting surface of said light emitting diode and being flush a surface of the light carrier, said light guide element having a recess formed therein being shaped for plugging-in said light emitting diode with a large part of said light-emitting surface of said light emitting diode being enclosed by said light guide element; and
said light emitting diode and said light guide element defining an air gap therebetween.
2. The lighting element according to claim 1 , wherein said light exit surface of said light guide element is at least one of flat and roughened.
3. The lighting element according to claim 1 , further comprising silicone cast around said light emitting diode.
4. The lighting element according to claim 1 , further comprising a sleeve installed in said light carrier, said light emitting diode and said light guide element are held in said sleeve.
5. The lighting element according to claim 4 , wherein said sleeve is glued in the light carrier and has passages formed therein through which excess adhesive can escape to an exterior of the light carrier.
6. The lighting element according to claim 1 , wherein the light carrier is a ceiling or wall of an aircraft cabin, said light emitting diode emits white light.
7. The lighting element according to claim 1 , wherein the lighting element is part of a lighting configuration.
8. A lighting element, comprising:
a light emitting diode to be installed in a light carrier;
a light guide element optically coupled to said light emitting diode, said light guide element having a smaller light exit surface than said light emitting diode;
a sleeve having an end face and being installed in the light carrier, said light emitting diode and said light guide element being held in said sleeve; and
said light exit surface of said light guide element, said end face of said sleeve and a surface of the light carrier being flush.
