Title
(EN) MOTOR VEHICLE INDICATOR NEEDLE
(FR) AIGUILLE POUR INDICATEUR DE VEHICULE AUTOMOBILE
Abstract
(EN)
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.
(FR)
La présente invention concerne une aiguille lumineuse pour appareil indicateur de véhicule automobile, comprenant un canon (150) et un index (110) qui lui est transversal, caractérisée par le fait que l'index (110) comporte une chambre borgne (120), incurvée, qui débouche sur la surface inférieure (116) de l'index (110) et qui couvre au moins le canon (150), dans son extension longitudinale. La surface inférieure de la chambre a pour fonction principale de réfléchir une partie des rayons lumineux provenant du canon (150), en direction de l'index (110) vers l'avant de celui-ci. La surface supérieure de la chambre (120) a pour fonction principale de filtrer et d'homogénéiser le flux lumineux en provenance du canon (150) qui la traverse et qui parvient à la paroi avant de l'index (110). L'invention permet ainsi un éclairage homogène de l'index (110) sur toute sa longueur.
