| 摘要 |
The present invention relates to an indicator device with a pointer, in particular for motor vehicles, of the known type comprising: an indicator apparatus (310), a rotary control shaft (312), driven by the indicator apparatus, an illuminating pointer connected to the control shaft (312), a light source (200) and an optical guide (100), which is optically transparent, placed facing the light source (200) and on the rear of the pointer, in order to direct towards the latter at least a portion of the light generated by the light source (200), characterised in that the optical guide (100) comprises structures (130, 140, 150, 152, 154, 156, 158, 160, 162) with reflecting prism effect, and based on triangular prisms (130, 140), adapted to return the light coming from the light source (200) towards the illuminating pointer, in a substantially homogeneous manner, over a zone with an angular aperture of 360 DEG around the axis (121) of the control shaft (312) and of the pointer. <IMAGE> |
