Abstract
A lighting arrangement includes at least a first and a second LED lighting element arranged next to each other on a carrier surface. The spacer element has, at least in a portion thereof which is in contact with the second LED lighting element, a width which is less than 20% of a width of the first LED lighting element. The first LED lighting element comprises a spacer element projecting into a direction in parallel to the carrier surface. The second LED lighting element is arranged in contact with the spacer element such that it is arranged aligned relative to the first LED lighting element, and such that the first and second LED lighting elements are arranged at a distance forming a gap between the first and second LED lighting elements.
Claims15
A lighting arrangement, comprising:
- at least a first LED lighting element and a second LED lighting element arranged next to each other on a carrier surface, the first LED lighting element and the second LED lighting elements being arranged at a distance forming a gap between the first LED lighting element and the second LED lighting element, wherein
- at least the first LED lighting element comprises at least one of a plurality of spacer elements projecting into a direction at least substantially in parallel to the carrier surface extending over the gap,
- the second LED lighting element being arranged in contact with at least one of the plurality of spacer elements (such that the second LED lighting element is arranged aligned relative to the first LED lighting element, the at least one of the plurality of spacer elements having, at least in a portion thereof being in contact with the second LED lighting element, a width which is less than 20% of a width of the first LED lighting element, and
- the at least one of the plurality of spacer elements are formed integrally with an optically active part of the first LED lighting element, the optically active part emitting light during operation of the first LED lighting element.
(canceled)
A vehicle headlight, comprising:
- a lighting arrangement including
- at least a first LED lighting element and a second LED lighting element arranged next to each other on a carrier surface, the first LED lighting element and the second LED lighting element being arranged at a distance forming a gap between the first LED lighting element and the second LED lighting element, wherein
- at least the first LED lighting element comprises at least one of a plurality of spacer elements projecting into a direction at least substantially in parallel to the carrier surface extending over the gap,
- the second LED lighting element being arranged in contact with at least one of the plurality of spacer elements such that the second LED lighting element is arranged aligned relative to the first LED lighting element, the at least one of the plurality of spacer elements having, at least in a portion thereof being in contact with the second LED lighting element, a width which is less than 20% of a width of the first LED lighting element, and
- the at least one of the plurality of spacer elements are formed integrally with an optically active part of the first LED lighting element, the optically active part emitting light during operation of the first LED lighting element.
Method A method of manufacturing a lighting arrangement, comprising the steps of arranging a first LED lighting element on a carrier surface, the first LED lighting element comprising at least one of a plurality of spacer elements projecting into a direction at least substantially in parallel to the carrier surface, the at least one of a plurality of spacer elements having, at least in a portion thereof being in contact with a second LED lighting element, a width which is less than 20% of a width of the first LED lighting element,
- arranging at least the second LED lighting element on the carrier surface next to the first LED lighting element to be in contact with the at least one of the plurality of spacer elements, such that the second LED lighting element is arranged aligned relative to the first LED lighting element and such that the first LED lighting element and the second LED lighting elements are arranged at a distance forming a gap between the first LED lighting elements and second LED lighting elements and that the spacer element extends over the gap,
- wherein the at least one of the plurality of spacer elements are formed integrally with an optically active part of the first LED lighting element, the optically active part emitting light during operation of the first LED lighting element.
