Rotative indicator system with power lighting source

Abstract

The invention is a rotating pointer system with electric light source, comprising at least a rotating pointer and a rotating shaft module of the rotating pointer, where the rotating pointer and the rotating shaft are linked through shaft. And the surface of the rotating shaft module is coated with plural annular electrodes comprising a coaxial outer annular electrode and a coaxial inner annular electrode; and the one side of the rotating pointer is opposite to the first surface of the rotating shaft module and plural semiannular electrodes are coated relative to plural annular electrodes, and these semiannular electrodes have plural electric coupling spring electrodes. The contact between the spring electrodes and plural annular electrodes can electrically couple plural semiannular electrodes with plural annular electrodes. Thus, at least an electric light source electrically coupled with plural annular electrodes on the rotating shaft module can be placed at the point of or on a second surface of the rotating pointer for lighting.

Description

technical field [0001] The present invention relates to a rotary pointer, in particular to a rotary pointer with an electric power supply. Background technique [0002] Rotating pointers are widely used in many human-machine interface instruments, such as watches, wall clocks, and automobile and motorcycle instruments. To read the index in the dark, the rotating pointer is usually covered with or at least decorated with fluorescent material at the tip. In addition, an external light source can also be installed on the back panel of the instrument to illuminate the rotating pointer. [0003] Please refer to figure 1 As shown, it is a schematic diagram of a traditional timepiece 100 . The timepiece 100 includes a plurality of rotating pointers 110, and here, the tip 120 of each of the plurality of rotating pointers 110 is decorated with a fluorescent material, so that the indicated place can be seen in a dark place. In addition, an illumination source 130 such as a light b...

Problems solved by technology

[0004] However, in some dark environments, the visual effect of fluorescent materials is not ideal

Furthermore, limited by the degree of luminescence and installation location, the light source provided by the lighting source cannot illuminate all possible indication positions of the above-mentioned rotating pointer.
