Abstract

Ring lighting unit (1) can be fastened to lens (3) in the manner shown in fig.2. In this position the light channel (10) (fig.3) connects to flashlight (5). When a photograph is taken the light from the flashlight will therefore be guided through a light channel (10). This channel (10) comprises walls (6, 7, 8, 9) and transitions therebetween. Light channel (10) transposes into in a reflection chamber which is bounded by annular reflector (13) and edge (12). In the mounted position the reflection chamber is further bounded by lens edge (21). A light diffuser (20) can be placed on the front side of the reflection chamber. Reflecting mirror (19) is arranged at the end of light channel (10) in a manner such that light from flashlight (5) is reflected to annular reflector (13). In order to enhance this, edges (12) and (21) can be provided with reflective material.
