LED scanning indicator

摘要

The device has a light source with at least one light emitting diode (6) for producing a light beam (7) that can be selectively deflected by a movable deflection arrangement to different areas of a display surface (4). The movable deflection arrangement contains a continuously rotating rotary body (10), especially a rotary mirror. An optical system (8,18) is provided for focusing the light beam on the display surface and a control arrangement is provided for intermittently driving the LED. An independent claim is also included for a method if indicating information with light on different regions of a display surface.
