Abstract

An illumination device comprises at least one LED (36), which can be connected through circuit means (50) to a voltage source optionally formed by a battery unit (70) or an accumulator unit (74). Furthermore, a first contact means (60) is provided for connecting the battery unit (70) and a second contact means (64) for connecting the accumulator unit (74) to the circuit means (50). A bottom unit for a battery grip (11) comprising a grip sleeve (90) in which the accumulator unit (74) is arranged, has a basic body (84) mountable at the lower end of the grip sleeve (90), wherein an upper contact element (89) for contacting the accumulator unit (74) and a lower contact element (95) for contacting a contact element (107) of a charging station, to which a current is applied, are arranged in the basic body (84). An electronic circuit unit (99) having a microprocessor (1) is connected between the upper and the lower contact elements (89, 95), which electronic circuit unit (99) is formed and configured such that it controls a charging process for charging the accumulator unit (74).
