Flashing, illuminated sign formed with LEDs, in the form of an illuminated house number or an illuminated roadside warning triangle.

摘要

An illuminated sign is formed with LEDs 6 to provide the illumination and is in the form of an illuminated house number or letter, or an illuminated roadside warning triangle (Fig. 6). The LEDs may be continuously illuminated or they may flash. If formed as an illuminated house number this flashing may be used to indicate an emergency and to help emergency services locate the house. The sign is preferably adapted to be powered from an external power supply such as a mains power supply or a cigarette lighter socket of a vehicle.
