Use light emitting diode can the Luminous kite of self power generation and method of work thereof
Technical field
The present invention relates to outdoor toy art, especially, relate to a kind of kite.
Background technology
Kite is a kind of traditional outdoor toy, has a long history, generally liking by people;Lack illumination due to height in the air, therefore, make kiteflying at night become the most difficult activity.And along with people gradually become accustomed to night life, demand be there is also for kiteflying at night;To this, need to make to have on kite illuminator, just can see the kite in high-altitude.But, owing to being in high aerial kite distance ground farther out, therefore, according to low pressure aneroid battery to the power illuminating device on kite, to produce the illumination of lasting higher brightness, battery will quickly exhaust, and make kite need frequently and change battery or charging, therefore, practicality is poor, it is difficult to promote.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of Luminous kite, this Luminous kite can provide with the form of self power generation in the air at height and continue and powerful lighting effect.
The technical solution adopted for the present invention to solve the technical problems is: this Luminous kite includes sail and the draught line being fixed on sail;Described sail central authorities are additionally provided with an impeller that can rotate windward;The sail of described impeller periphery is provided with a sensing ring of encirclement;One in described impeller and the sensing ring of encirclement is shaped with power coil, and another one is permanent magnet;Described permanent magnet radial magnetizing, the coil plane of described power coil is orthogonal to the magnetizing direction of described permanent magnet;The outfan of described power coil is by being delivered to the illuminator being located on described sail after Voltage stabilizing module.
As preferably, described illuminator is the Light-Emitting Diode being embedded on described sail.
As preferably, described draught line is made up of the optical fiber blending impurity, and it is connected on described sail by a fiber connector, and the aperture of described fiber connector is towards described illuminator.
As preferably, described impeller is a centrifugal fan wheel, and is made up of ferromagnet, and this centrifugal fan wheel overall radial magnetizes into permanent magnet;The described sensing ring of encirclement is surrounded by the power coil laid around described centrifugal fan wheel.
Improving the most further as above-mentioned, the leaves density of the half cycle of described centrifugal fan wheel is more than the leaves density of another half cycle.
The beneficial effects of the present invention is: this Luminous kite is after rising to high-altitude, there is in the air powerful air-flow due to height, therefore, the impeller of kite sail central authorities will rotate rapidly, thus produce a lasting more superpower electric current by electromagnetic induction, provide lasting highlight illumination for described illuminator;The superiority environment energy that when this kite have employed use, self is residing, has abandoned traditional battery and has powered, and is allowed to without charging or changes battery, so that its practicality is greatly improved.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
In the embodiment shown in fig. 1, this Luminous kite includes a sail 1 triangular in shape and the draught line 5 being fixed on sail 1;Described sail 1 central authorities are provided with an impeller that can rotate windward 2;The sail of described impeller 2 periphery is provided with a sensing ring of encirclement 3.
In the present embodiment, described impeller 2 is a centrifugal fan wheel, it is that cover cap shape is towards direction of the wind comes from, blade ring is on the periphery being arranged in this impeller, after the circular hood head-on blown is lived by the bottom surface of this impeller, guide surrounding, radially promote each blade of impeller side, thus drive impeller to rotate continuously.Described impeller 2 is made up of ferromagnet, and radially magnetizes into permanent magnet.
The described sensing ring of encirclement 3 is surrounded by a series of power coils laid around described impeller 2;The coil plane of each described power coil is orthogonal to the magnetizing direction of described permanent magnet;The outfan of described power coil is by being delivered to each light emitting diode 4 being located on described sail 1 after Voltage stabilizing module.
Above-mentioned Luminous kite, described draught line 5 is made up of the optical fiber blending impurity, and it is connected on described sail 1 by a fiber connector 6, and the aperture of described fiber connector is towards at least one light emitting diode 4.Now, the illumination of described light emitting diode 4, can be delivered on whole draught line 5 by fiber connector 6, and, in draught line 5 in transmittance process, by the impurity scattering within draught line, make whole piece draught line 5 luminous, consequently facilitating see position and the trend of draught line 5 clearly, it is possible to prevent draught line 5 to be hooked into the objects such as branch.
Centrifugal fan as described impeller 2 is taken turns, one embodiment as shown in Figure 2: this centrifugal fan take turns include for catching distinguished and admirable bottom surface 21, this center, bottom surface 21 is axis hole 20, has blade 23 and vane ring 22 ring week.In the present embodiment, the leaves density of the half cycle of this centrifugal fan wheel is more than the leaves density of another half cycle, in Fig. 2, i.e. has the leaves density leaves density more than left half cycle of half cycle.Having the prominent advantages that of the program, impeller 2 is in rotary course, air-flow is discharged to surrounding from side, and this density is uneven, and this kind of inhomogeneities continuous circulation rotating of wound impeller surrounding, cause the air pressure consecutive variations on the sail surface of impeller periphery, so that sail rocks continuously, the more conducively rapid increase of kite.
Above-mentioned Luminous kite is after rising to high-altitude, there is in the air powerful air-flow due to height, therefore, the impeller 2 of kite sail 1 central authorities will rotate rapidly, thus produce a lasting more superpower electric current by electromagnetic induction, provide lasting highlight illumination for illuminator (for light emitting diode in the present embodiment);The superiority environment energy that when this kite have employed use, self is residing, has abandoned traditional battery and has powered, and is allowed to without charging or changes battery, so that its practicality is greatly improved.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
