Optimized printed circuit board

摘要

The present invention relates to a printed circuit board (100, 200) comprising several finger portions (102, 103, 104) projecting from a base portion (101), wherein each linger portion is provided with a plurality of light emitting elements (106). By means of the invention it is possible to optimize the physical size of the printed circuit board (100, 200) such that a resulting LED module requires less printed circuit board area per thereon arranged LED, thereby decreasing the cost of the overall LED module.

主权项

1. A printed circuit board comprising:
a base portion, at least three finger portions extending in a transversal direction with respect to said base portion and being substantially parallel to each other, wherein two adjacent finger portions define an intermediate aperture with a shape corresponding to at least one of the finger portions, wherein the at least three finger portions each have a plurality of longitudinal protrusions distributed along at least a first side of the at least three finger portions, wherein each of the at least two finger portions is provided with a plurality of light emitting elements aligned in a first and a second row and wherein light emitting elements of at least one of the first or the second row are arranged on the protrusions, wherein an intermediate finger portion comprises an end portion protruding longitudinally, wherein light emitting elements are arranged on the end portion.
