LED LIGHTING APPARATUS WITH A BATTERY MONITORING DEVICE

摘要

A portable lighting apparatus comprising a re-chargable battery and a plurality of LED's (light emitting diode) located on a PCB are housed in separate enclosures. The battery is managed by a first microprocessor in the battery enclosure and operation of the LED(s) is managed by a second microprocessor in the lamp enclosure. The two microprocessors are connected to respective data transmitters which generate signals to pass information and/or commands between the two microprocessors. The electrical systems of the two enclosures are interconnected by a bi-direction data link formed by a twin core cable.
