Abstract (en)
[origin: EP0523903A2] A rechargeable electronic flasher circuit is powered by a solar panel (21) and solar-rechargeable battery. The circuit has particular application as an auxiliary safety measure for use in reflecting roadstuds (20) or in memorial symbols for mounting on, or near, gravestones and the like so as to provide substantially perpetual illumination. Minimum charging time is necessary, while operation on battery power is extended to many days, rather than hours. The circuit can also be set to flash at a rate above the critical frequency of fusion that the eye can distinguish, creating a substantially constant light. The flashing light may also be used in a roadside warning lamp. <IMAGE>
