Abstract:
A rotational obstruction and beacon signaling apparatus, in which chip-on-board (COB) packaged light emitting diodes (LEDs) are employed to provide a flashed emission pattern with high luminous intensity. The flash sequence of individual LEDs is controlled by an electronic timing circuit to simulate a rotational or other motional signaling effect.
