L'invention se rapporte à une aiguille d'affichage électroluminescente (1) pour un objet portable, telle qu'une pièce d'horlogerie ou un instrument de mesure pour fournir une indication horlogère ou de mesure. L'objet portable comprend une source d'alimentation en énergie électrique. L'aiguille d'affichage comprend un agencement de deux diodes (3, 13) montées tête-bêche l'une connectée en parallèle de l'autre et avec au moins une des deux diodes, qui est une diode électroluminescente. Les deux diodes son agencées pour être reliées à la source d'alimentation en énergie électrique de l'objet portable.

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.

An instrument display for a vehicle dash includes a unique light source and light guide assembly. The light source is incorporated directly into the light guide. A non-contact magnetic coupling transfers power from a circuit board to the light source. A textured surface is formed on one portion of the external surface of the light guide to evenly illuminate the light guide. Also, surface roughness on an opposing external surface portion of the light guide is varied depending on the length of the light guide to provide similar luminance for light guides having different lengths.

La présente invention concerne un dispositif indicateur à aiguille du type utilisé généralement dans les tableaux de bord de véhicules automobiles. Plus précisément, la présente invention concerne un tel type de dispositif comportant un arbre d'entraînement creux (12) entraîné en rotation par un moteur conventionnel et à l'intérieur duquel est logée l'aiguille (4), par sa tige. L'invention prévoit une pluralité de modes de réalisation comportant chacun un type de liaison mécanique particulier permettant d'améliorer le démontage de l'aiguille hors de l'arbre creux, sans endommager ni l'aiguille, ni l'arbre. Ainsi, une même aiguille peut être démontée de l'arbre puis remise en place plusieurs fois avant de devenir trop endommagée pour être encore utilisable.

This invention is to provide a display device for a vehicle in which with the pointer portion of light transmission type placed over characters etc, the value indicated by the pointer portion can be accurately read with high visibility. A display device for a vehicle comprises a dial (1) and an indicating board (7) laid on the dial (1). The dial (1) includes a disk-shaped light transmitting portion (2a), light transmitting characters (3a) and graduations (3b) outside the light transmitting portion (2a), and an annular light transmitting portion (2b) outside the characters (3a) and the graduations (3b). The indicating board (7) includes a light transmitting pointer's inner end portion (8a) and a light transmitting pointer's outer end portion (8b) which overlap the light transmitting portions (2a,2b) of the dial (1), respectively, and an annular light transmitting portion (10) which is laid over the characters (3a) and the graduations (3b).

Bei einem Anzeigeinstrument ist auf einer von einer Zeigerwelle (1) gehaltenen Kappe (2) eine Rinne (4) aus lichtundurchlässigem Material befestigt, welche zur Betrachterseite hin offen ist und in die ein Zeiger (5) aus lichtleitendem Material eingesetzt ist. Der Zeiger (5) hat eine Rastnase (6), mit der er an der Kappe (2) verrastet ist.

An illuminated pointer includes an outer pointer that surrounds an inner pointer. The outer pointer extends from a base and is generally elliptical. The inner pointer extends from the base into the void of the outer pointer. The illuminated pointer utilizes a single light source for illuminating both the outer and inner pointer. The inner pointer provides easier reading of a dual scale gauge such as with a speedometer having both English and Metric speed scales.
摘要:
A pointer lighting device which can improve a light introduction efficiency to an indicating unit, and is bright and small in lighting non-uniformity, and which comprises a pointer (7) having a translucent indicating member (indicating unit) (72) and a light introducing member (light introduction unit) (73), and being operated around and by the drive shaft (1) of a drive device (2), and a light source (L) disposed around the drive shaft (1), for allowing the indicating member (72) to emit light via the light introducing member (73), wherein the light introducing member (73) has a light receiving surface (73a) for receiving a light from the light source (L), a first reflection surface (73b) for condensing a light introduced from the light receiving surface (73a) toward the rotation axis (Va) position of the drive shaft (1), a second reflection surface (73c) formed between this first reflection surface (73b) and the rotation axis, for reflecting a light from the first reflection surface (73b) in a direction along the rotation axis (Va), and a third reflection surface (73d) formed on the rotation axis (Va) so as to face the second reflection surface (73c), for reflecting a light from the second reflection surface (73c) in the longitudinal direction of the indicating member (72).
