Optical symbol generator using movable LED devices - has LEDs selectively activated as carrier moves to create symbol image

摘要

The optical symbol representing device includes a light bar (1) providing support for a number of separate light source (2), eg LED devices. The bar is produced as a movable element mounted on an arm (3). This is pivot mounted on a base (4) and has an actuator for the motion. Each LED has a separate connector (5) to a control stage (6), coupled to control electrons (7), eg a microprocessor. The controller also has a coupled clock generator (9), input stage (10) and memory (8). A matrix alphanumeric (or other) symbol can be displayed by activating specific LED devices as the carrier is moved (A) with a specific number on view. USE/ADVANTAGE - Provides optical symbol display using moving element.
