| 摘要 |
The invention concerns a luminous needle for a motor vehicle indicator device, comprising a bushing (150) and a pointer (110) transverse thereto, characterised in that the pointer (110) comprises a curved blind chamber (120) emerging on the pointer (110) lower surface (116) and covering at least the bushing (150), in its longitudinal extension. The chamber lower surface serves mainly to reflect part of the luminous rays coming from the bushing (150) towards the pointer (110) frontward thereof. The chamber (120) upper surface serves mainly to filter and homogenise the light flow coming from the bushing (150) which passes through it and reaches the pointer (110) front wall. The invention thus provides a homogeneous illumination of the pointer (110) over its entire length. |
