Problems solved by technology

On the other hand, given the ability of the hands to move relative to the UV light source, they will not always receive the same amount of UV light, so their brightness may vary
A third drawback lies in the mediocre conversion efficiency between visible light and ultraviolet radiation

Embodiment Construction

[0015] The invention proceeds from the general inventive idea of ​​illuminating display hands for portable objects such as wrist watches or measuring instruments by means of point light sources, preferably light-emitting diodes. This luminous display pointer has several advantages: its appearance does not degrade over time, and thanks to the wide variety of light-emitting diodes, it is possible to modify the appearance of the pointer and thus of the portable object on which it is mounted. Personalized so that it can stand out from the competition. Furthermore, according to another advantage of the invention, the light source is arranged on the pointer for which it is used, and not, for example, in the driving arbor of the pointer, which greatly simplifies the design of the pointer and their connection to the frame of the portable object. Electrical connections for electrical energy sources.

Abstract

The invention relates to set of luminous display hands for a portable object which houses an electrical energy supply source, the set of luminous display hands including first and second superposed luminous display hands each provided with a hole for the passage of a drive arbour, the drive arbour of the second luminous display hand being arranged concentrically inside the drive arbour of the first hand with insertion of an insulating layer between the two drive arbours, the first and second luminous display hands respectively carrying a first and a second light source, the first pole of the first light source being electrically connected to a first terminal of the power supply source via the drive arbour of the first luminous display hand, the second pole of the first light source being connected to the first pole of the second light source via a contact piece, and the second pole of the second light source being connected to the second terminal of the power supply source via the drive arbour of the second luminous display hand.

Description

technical field [0001] The present invention relates to a set of illuminated display hands for portable objects. In particular, the invention relates to a set of illuminated display hands for a timepiece such as a wristwatch or a measuring device with an analog display. Background technique [0002] Watch hands are manufactured to tight tolerances. The holes in the pointer for passage through the tubing are typically made with precision on the order of microns. This precision is necessary to ensure that the pointer is pushed correctly on its arbor. Pointers are usually made of sheet metal no thicker than a few hundred microns. In order to reduce the thickness of the watch, the distance between the hands and the crystal is usually no more than 1 millimeter, and the distance separating two coaxial hands (for example, hour and minute hands) is on the order of fractions of a millimeter. [0003] Watch hands obviously have a functional role such as indicating the current time...
