Abstract

The present invention relates to a rotative light emitter assembled in a rotating member, and comprising a encase fixed in said rotating member, a coil assembly fixed in a chamber of the encase, a shaft pole pivotally attached to the encase, a set of magnets provided on the shaft pole and pivoting coaxially with the shaft pole, a light emitting assembly electrically connected with the coil assembly and a counterweight unit fixed on the shaft pole. When the encase rotates but the shaft pole does not rotate, a relative rotation between these two occurs, and a relative motion between the magnet and the coil assembly occurs, so that the coil assembly induces an electromotive force to actuate the light emitter lightening. The rotative light emitter has a light alarming function, so that it can increase the novel sense and will not be influenced by the amount of the air intake.

Description

The rotation illuminator

[technical field]

The present invention relates to a kind of illuminator, the rotation illuminator that can emit beam after particularly a kind of rotation.

[background technology]

With reference to Fig. 1, a kind of known wheel cover is to have a lid body 10, a turn seat 11, a permanent magnet 12, a coil assembly 13 haply, and most luminescence components 14.Aforementioned wheel cover mainly is that each luminescence component 14 and coil assembly 13 are electrically connected, relend by lid body 10 when rotating along with wheel, air by a plurality of fresh air inlets 101 of lid on the body 10 by lid body 10 and act on each blade 111 of this turn seat 11, to drive this turn seat 11 and this permanent magnet 12 with respect to coil assembly 13 rotations, at this moment, coil assembly 13 can cut the magnetic line of force that permanent magnet 12 produced and produce an induction electromotive force and make each luminescence component 14 produce light sources.Only the turn seat 11 of aforementioned wheel cover must drive by the air that is entered by each fresh air inlet 101, and when intake reduces, the rotating speed meeting of turn seat 11 thereby slow down, its illumination effect also can with influence, this situation can occur in as the vehicle gait of march when slow, and the mud foreign matter on the road surface is when spattering on the fresh air inlet 101 of wheel cover, that is, described wheel cover still remains to be broken through on the problem of aforementioned intake, how this case promptly at allowing permanent magnet 12 and the coil assembly 13 can relative turn, and the part that is not subjected to the intake influence is improved.

[summary of the invention]

The object of the present invention is to provide a kind of rotation illuminator, possess the light-emitting caution effect and promote under the prerequisite of novel visual sense effect, can not be subjected to the intake influence, and use for the present invention and rotate the design that does not need air inlet on the revolving part of illuminator assembling, can increase the scope of application of the present invention.

For reaching above purpose, a kind of rotation illuminator of the present invention, be to be assembled on the revolving part, this rotation illuminator comprises a housing that is fixedly installed in the printing opacity on the described revolving part, one is fixedly mounted on the interior coil block of room of this housing, one rotatably is articulated in the axostylus axostyle on this housing, one be sheathed on this axostylus axostyle and can with the magnet of the coaxial pivot of this axostylus axostyle, and one and the luminescence component that electrically connects of this coil block, this coil block comprises one around a central axis and define the circular base of a magnetic field space, one around the coil that is arranged at this pedestal periphery, and two be assembled in the pedestal both sides respectively and around the sense magnet ring sheet of this central axis, and this sense magnet ring sheet is to electrically connect with this coil, this magnet is to be assembled in this magnetic field space, this luminescence component is to feel the magnet ring sheets with two of this coil block to electrically connect, it is characterized in that: this rotation illuminator also comprises a counterweight element that is installed on this axostylus axostyle, this axostylus axostyle is to rotate freely on this central axis and have a mounting end that stretches outside the housing, this counterweight element is the mounting end that is installed on this axostylus axostyle, is used for making this axostylus axostyle to be constant at a position and does not rotate.

Described rotation illuminator is characterized in that: this counterweight element can have the combined hole that a conical body, is positioned at this body top, and one away from this combined hole and be positioned at the weight district of conical body bottom.

Described rotation illuminator is characterized in that: this weight district places this conical body bottom part with the higher metal displacer of density.

And rotating the effect and the advantage of illuminator, the present invention is:

One, during rotation, this counterweight element 8 not influenced by air inflow and have caution and increase the effect of novel visual sense: owing to can limit rotating around himself axis of this axostylus axostyle 6, therefore, when this housing 4 rotates along with described revolving part 3 with coil block 5, coil block 5 promptly can relative to this axostylus axostyle that does not rotate 6 on affixed magnet 71 produce the cutting magnetic line phenomenons, it is luminous that the electromotive force that is produced can drive each luminescence component 72, so, the present invention rotates illuminator 2 need not be subjected to the air inlet promotion and turn really, and can reach caution and the effect that increases novel visual sense by the light of each luminescence component 72.

Two, rotate on the revolving part 3 that illuminator 2 assembled for the present invention being used for, do not need to have again the relevant design of air admission hole, can increase the scope of application of the present invention, for example can be widely used in the vehicle runner, on rotation facility and the recreation facility: because housing 4 need not driven by air with relatively rotating of axostylus axostyle 6, really on described revolving part 3, can impose the design of air admission hole again, moreover, no matter whether the rotation 30 of described revolving part 3 is overlapping with the central axis 50 of illuminator, when described revolving part rotates, all can fall in ground and axostylus axostyle 6 is positioned a position and not rotate, make the present invention rotate illuminator 2 and emit beam by counterweight element 8 perseverances.

Take a broad view of above-mentionedly, the present invention really can provide a kind of rotation illuminator of practicality.
