LED display for e.g. advertising logo of vehicle manufacturer at vehicle wheel, has disks electrically connected with LEDs and pattern such that disks, pattern and LEDs form circuit, where LEDs are illuminated

摘要

The display has a printed circuit board (1) at which LEDs (10) of different colors such as red, green and blue, arranged over each other are present. Another board (2) with flexible disks (20) is arranged at a rotational axis of a rotary body. The boards are rotated by the body. The disks contact a pattern of a third board, where the pattern is made of copper foil. The third board is electrically connected with the LEDs. The disks are electrically connected with the LEDs and the pattern such that the disks, the pattern and the LEDs form a circuit, where the LEDs are illuminated.
