Abstract

The invention relates to an illuminating device (1) for a photographing means, in which the light source (3) is in the immediate vicinity of the lens (2), inside the photographing means, and the light (4; 40) emitted by the light source is adapted through said lens to illuminate an approximately rectangular area (5). The light source of the flashlight device (1) is a LED (3), which emits circular symmetrical light. The lens (2) comprises a light-refractive area and a totally light-reflective area, the lens being made of one monolithic piece.
