Set-top flash lamp of camera

Abstract

A set-top flash lamp of a camera, comprising a lamp holder (2) and a lamp cap (1). A battery accommodating cavity (4) and a battery accommodating cavity cover (3) are formed in the lamp holder (2). A lithium battery (5) is accommodated in the battery accommodating cavity (4), and the lithium battery (5) comprises an electrical output contact (6). The electrical output contact (6) is in the shape of a right-angled sheet, and is composed of end surface right-angled sides (61) and bottom surface right-angled sides (62), wherein the end surface right-angled sides (61) are located on the front end surface (51) of the lithium battery (5); and the bottom surface right-angled sides (62) are arranged on the bottom surface (52) of the lithium battery (5). An electrical access contact (7) is contained in the battery accommodating cavity (4), and is arranged on a side wall of the battery accommodating cavity (4) which is opposite to the bottom surface (52) of the lithium battery (5). The set-top flash lamp improves the performance and reduces the costs.
