Abstract
A portable rechargeable lighting device uses software in a microcontroller to turn on a charger protection circuit when a charging circuit is activated, to monitor at least one electrical characteristic relative to a rechargeable battery, to control at least one charging parameter of the charging circuit, and to alert a user of a low battery condition before light emitted from the device terminates.
Claims1
A portable rechargeable lighting device, comprising:
- a portable housing which houses at least one rechargeable battery and a light source;
- an electronic circuit which provides power from the at least one rechargeable battery to the light source;
- a pair of charging contacts;
- a battery monitoring circuit to monitor at least one electrical characteristic relative to the at least one rechargeable battery configured within the portable housing;
- a microcontroller configured within the portable housing;
- a recharging device with a pair of recharging contacts which configured to charge the at least one rechargeable battery when the pair or recharging contacts are in electrical contact with the pair of charging contacts;
- and
- a charging detection circuit which detects when the pair of recharging contacts are in electrical contact with the pair of charging contacts;
- wherein software within the microcontroller is programmed to turn on a charger protection circuit when the charging detection circuit detects the pair of recharging contacts are in electrical contact with the pair of charging contacts.
