Circuit board with a regular LED assembly

摘要

The printed circuit board (2) has a regular arrangement of positions (4,6) for mounting with light-emitting diodes, and a rectangular basic shape, where the light-emitting diode-positions are arranged in columns and rows parallel to the both sides of the rectangle. The light-emitting diode-positions are controlled in two different groups or are assembled with two groups of different light-emitting diodes. The printed circuit board has a shorter side (8) and a longer side (10), and the columns and rows are different along the both sides.
