Abstract:
1. An electrical pack to illuminate at least one electroluminescent (EL) lighting element positioned on a garment sized to be worn by a human, the electrical pack coupled to the garment, the electrical pack comprising: rechargeable batteries to power an EL driver circuit to illuminate the EL lighting element in an EL illumination mode of the electrical pack; a charging circuit coupled to the rechargeable batteries to charge the rechargeable batteries in an electrical pack charging mode; an input jack coupled to the charging circuit to receive electrical energy in the electrical pack charging mode and to power the charging circuit in the electrical pack charging mode to charge the rechargeable batteries; and a charge state indicator circuit coupled to the charging circuit and the EL driver circuit, the charge state indicator circuit associated with the electrical pack charging mode and the EL illumination mode, the charge state indicator circuit including at least one LED lamp, wherein in the electrical pack charging mode the charge state indicator circuit is adapted to illuminate the at least one LED lamp to a first color while the electrical pack is in the electrical pack charging mode, and, while the electrical pack is in the EL illumination mode, the charge state indicator circuit is adapted to illuminate the at least one LED lamp to a second color other than the first color.
