DETAILED DESCRIPTION

[0044] FIG. 1 illustrates a flash device system 1 according to one example. The flash device system 1 is arranged to be used for photographic purposes. According to one example, the flash device system 1 is arranged to be releasably attachable to a camera. The flash device system 1 comprises in the illustrated example a flash holder 20 and a flash housing 2 hinged onto the flash holder 20. The flash device further comprises a releasable battery 30, attached to the flash holder 20. The flash housing is equipped with a lens element 3 arranged to affect the generated flash light in a desired way. According to one embodiment, an exterior surface 40 of the battery 30 forms an exterior surface 40 of the flash holder 20 when the battery 30 is attached to the flash holder 20.

[0045] FIG. 2a-c illustrates a flash device 1a viewed from different angles. The flash device comprises a flash holder 20 having a battery accommodating cavity 25 formed therein and a flash housing 2 hinged onto the flash holder 20. The flash holder 20 comprises a battery accommodating cavity 25. The battery accommodating cavity 25 comprises electrical access contacts 26a, 26b; a battery locking protruding element 27; and a battery locking cavity 28. The battery locking protruding element 27 and the battery locking cavity 28 are arranged on opposite inner side walls of the battery accommodating cavity 25. The battery accommodating cavity 25 is arranged to accommodate a battery for the flash device 1a. According to one embodiment, the battery locking protruding element 27 and/or the battery locking cavity 28 comprises a spring loaded push button.

[0046] According to one embodiment, two of the electric contacts 26a of the battery accommodating cavity 25 are arranged to switch on a battery 30 placed in the battery accommodating cavity 25 when put in contact with the corresponding electric contacts of a battery 30 at the moment when the battery 30 is locked into a the battery accommodating cavity 25.

[0047] According to one embodiment not illustrated, the battery is attached to the battery accomodating cavity by means of magnetic engagement.

[0048] FIG. 3a-d illustrates a battery 30 for a flash device for photographic purposes viewed from different angles. The battery 30 comprises: electric contacts 36a, 36b; a cavity locking protruding element 37 and a cavity locking cavity 38 for engagement with a corresponding battery locking protruding element 27 and battery locking cavity 28 in a battery accommodating cavity 25. According to one embodiment, the cavity locking protruding element 37 and/or the cavity locking cavity 38 comprise a spring loaded push button. According to the illustrated embodiment, cavity locking protruding element 37 comprises a spring loaded push button. By pushing cavity locking protruding element 37, the battery may be released from for example a battery accommodating cavity 25 accommodated in the flash device 1a. In addition, the cavity locking protruding element 37 may be involved in locking the battery 30 into a battery accommodating cavity 25. As the battery is pushed into a battery accommodating cavity 25, the spring loaded cavity locking protruding element 37 is affected and when the battery 30 is in its final position in the battery accommodating cavity 25, the spring loaded cavity locking protruding element 37 springs back into its starting position, thereby locking the battery to the battery accommodating cavity 25.

[0049] According to one embodiment, two of the electric contacts 36a of the battery 30 are arranged to switch on the battery 30 when put in contact with corresponding electric contacts 26a of a battery accommodating cavity. By arranging two of the electric contacts 36a so that the battery 30 is switched on when the two electric contacts 36a are put in contact with corresponding electric contacts of a battery accommodating cavity, a safe battery is achieved, where the risk of accidentally starting the battery is reduced.

[0050] According to one embodiment, the battery 30 is of Lithium-ion type. According to one embodiment, two of the electric contacts 36a of the battery 30 are arranged to switch on the battery 30 when put in contact with the corresponding electric contacts 26a of a battery accommodating cavity 25, 45 at the moment when the battery 30 is locked into the battery accommodating cavity 25. By this construction, an even safer battery is achieved, wherein the risk of accidentally starting the battery is further reduced.
