Attorney, Agent or FirmInternational ClassA44C 003/00AbstractA modular electronic message badge has a detachable lamp unit which contains a light bulb associated with an interchangeable lens cover. A power pack unit provides one protected enclosure for receipt of electronic components or circuitry, and another portion defining a chamber, which opens to the exterior of the power pack unit for receipt of a battery. Introduction and removal of a battery from the chamber automatically switches on and off the electronic circuitry protectively enclosed within the power pack unit without requiring that such unit be opened. The lamp unit is physically attached to the power pack unit for support thereon and electrically connected therewith so that the light bulb is powered by an output of the electronic circuitry. The lens cover may be partially transparent and provided with a selected message or design. The cover is backlighted by the lamp to display the message intermittently, under the control of the power pack unit.Other References
