Abstract
An electromagnetic induction flashing stick comprises a casing, a magnet and LEDs, wherein the casing is a coaxial body formed by connecting a plurality of coils which are fewer than 20 in series; two LEDs with opposite polarity directions are connected to each coil; and the magnet is located inside the casing. The electromagnetic induction flashing stick can glow through electromotive force generated by the coils without a power supply, the flashing effect of the LEDs can be achieved, the cost is reduced, and energy conservation and environmental protection are achieved.
Description
Technical field
The utility model relates to a kind of flash rod, relates in particular to a kind of electromagnetic induction flash rod.
Background technology
In the epoch of this amusement nowadays, concert, theatrical evening etc. increases gradually, and the spectators at concert, theatrical evening scene much can hand flash rod and build on-the-spot ardent atmosphere, and the kind of flash rod is also more and more.General flash rod is to use button electronics or battery as power supply, and button electronics price is comparatively expensive, and battery then exhausts electric energy easily.
The utility model content
The purpose of this utility model provides a kind of electromagnetic induction flash rod, to solve deficiency of the prior art, reduces cost, and increases the life-span of flash rod.
A kind of electromagnetic induction flash rod, wherein, comprise shell, magnet and light emitting diode, described shell is the same axis body that is connected into to tens coils with several, at the light emitting diode of two opposite polarity directions of each coil connection, described magnet is positioned at the inside of shell.
Above-mentioned a kind of electromagnetic induction flash rod, wherein, described magnet be shaped as cylinder.
In sum, owing to adopted technique scheme, a kind of electromagnetic induction flash rod of the utility model can not use power supply, and luminous by the electromotive force of coil generation, can realize many light emitting diodes effect of flash of light again and again, reduce cost energy-conserving and environment-protective again.
Description of drawings
Fig. 1 is the structural representation of a kind of electromagnetic induction flash rod of the utility model.
The specific embodiment
Describe in detail below in conjunction with the specific embodiment of accompanying drawing to a kind of electromagnetic induction flash rod of the utility model.
See also Fig. 1, a kind of electromagnetic induction flash rod, wherein, comprise shell 1, magnet 2 and light emitting diode 3, described shell 1 is the same axis body that is connected into to tens coils with several, at the light emitting diode 3 of two opposite polarity directions of each coil connection, described magnet 2 is positioned at the inside of shell 1.
Above-mentioned a kind of electromagnetic induction flash rod, wherein, described magnet 2 be shaped as cylinder.
When described magnet 2 moved in coil, coil can produce induced electromotive force because of the variation of magnetic flux, and magnet 2 enters a coil and leaves a coil and can produce the opposite voltage of direction, so can make two light emitting diodes, 3 each self-luminous of opposite polarity direction.Just can make corresponding light emitting diode 3 luminous when having only the magnetic pole of magnet 2 in coil, to move, when two magnetic poles are simultaneously in a coil, can produce two magnitude of voltage is identical but voltage that direction is opposite, and cancel out each other, can not make light emitting diode 3 luminous.When a plurality of coils are connected into an overall coil, above-mentioned characteristic is arranged equally.At this moment different light emitting diode 3 is glistened again and again during at the inside of coil play when a magnet 2.When a plurality of magnet 2 magnetic pole opposites of the same name are placed on when rocking in the overall coil, can make a plurality of light emitting diode 3 simultaneously luminous.
Can change the length of shell 1 by the quantity that changes coil, simultaneously, the difference of putting into the quantity of shell 1 magnet 2 also can produce different effects, thereby also can connect the quantity that light emitting diode 3 increases light emitting diode 3 at the two ends of different coils.
In sum, owing to adopted technique scheme, a kind of electromagnetic induction flash rod of the utility model can not use power supply, and luminous by the electromotive force of coil generation, can realize many light emitting diodes 3 effect of flash of light again and again, reduce cost energy-conserving and environment-protective again.
More than preferred embodiment of the present utility model is described.It will be appreciated that the utility model is not limited to above-mentioned specific implementations, wherein the equipment of not describing in detail to the greatest extent and structure are construed as with the common mode in this area and are implemented; Any those of ordinary skill in the art, do not breaking away under the technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, or being revised as the equivalent embodiment of equivalent variations, this does not influence flesh and blood of the present utility model.Therefore, every content that does not break away from technical solutions of the utility model according to any simple modification, equivalent variations and the modification that technical spirit of the present utility model is done above embodiment, all still belongs in the scope of technical solutions of the utility model protection.
