Description
Technical field
This utility model relates to a kind of LED luminescent system, particularly relate to a kind of be performed relative motion by the Magnet on vehicle butterfly brake caliper and the inductor on vehicle hub and produced electric energy, and produced electric energy is supplied to LED by drive circuit, so that the LED luminescent system being mainly used in the motor vehicles such as automobile or electric motor car or bicycle that LED is luminous.
Background technology
Along with the fast development of science and technology, car has become people's daily life, has gone on a journey, goes to work and one of the important vehicles of tourism etc..At present, in order to enable vehicle to cause the attention of pedestrian and other vehicle when night travels, therefore, vehicular manufacturer are installation settings LED on the wheel hub of car, and be that LED is powered by storage battery or independent power supply, when vehicle in the process of moving can be luminous.When the LED being arranged on wheel hub is colourful, car the most just can send motley light, can either cause the attention of pedestrian and other vehicle, enhance safety, can play again decoration function.
At present, many Railway Car Plants use button cell or solaode etc. and provide working power for the LED being arranged on wheel hub, use the method can realize the power supply of LED to a certain extent, but have the disadvantage in that
1, use the defect that button cell is powered: the LED power according to being arranged on wheel hub varies in size, higher to the electricity stored by button cell and voltage request, and button cell electricity is limited, persistent period can only be about at 30～50 hours, so button cell have to be regularly replaced, a general low-power LED lamp driving voltage is 3.2V, the series connection button cell being so accomplished by two 1.5V is powered, if the LED string driving a 12V is the most difficult, volume will be the biggest, it is unfavorable for installing, change button cell the most frequent, relatively costly, installation button cell is loaded down with trivial details.In order to save button cell electricity, LED is made not work daytime, it is necessary to vibration switch to be set and optical switch is controlled by the consumption of electricity.There is above-described defect, so product can not popularity.
2, the defect of solar cell for supplying power is used: first solar cell for supplying power needs certain illuminance, the four wheels of automobile is perpendicular to ground, and four wheels is unlikely to be simultaneously in the face of sunlight, so each wheel is received, to shine upon be uneven.Limited additionally, due to by wheel volume size, the size of solar panel is also subject to certain restrictions that can not to be made the biggest impact attractive in appearance, moreover the charge lifetimes of solar storage battery can shorten increasingly along with the increased frequency of discharge and recharge, undercharge, causes LED normally not use.
Utility model content
In order to solve the problem in the presence of prior art, the purpose of this utility model is to provide a LED luminescent system that can be used in various types of vehicles, luminescent system provided by the utility model provides running voltage by the cooperation of the permanent magnet being arranged on vehicle butterfly brake caliper and the inductor being arranged on wheel hub for LED, solves to be continuously, in prior art, the problem that LED is powered.
In order to realize the purpose of this utility model, be the technical scheme is that at this
A kind of LED luminescent system on vehicle, including LED string, LED lamp drive circuit and permanent magnet, described LED string and described LED lamp drive circuit are separately mounted on wheel hub, and described permanent magnet is arranged on vehicle butterfly brake caliper；Described LED lamp drive circuit includes inductor, the rectification circuit being connected to the output of described inductor and is connected to the electric capacity C for storing electric energy of described rectification circuit output, the two ends of described LED connection in series-parallel to described electric capacity C.
Automobile is in the process of moving, wheel starts to rotate, the inductor being arranged on wheel hub rotates together along with wheel, and perform relative motion in being arranged on the permanent magnetism of geo-stationary on butterfly brake caliper, when inductor and permanent magnetism relative motion are by as far as recently, again by recently to remote process, inductor is received by the alternating current of once sinusoidal ripple, two pulse direct currents are become again through full-wave bridge rectifier circuit, the more stable unidirectional current of voltage is become for LED string by the filtering of electrochemical capacitor, the Capacity design of electric capacity be can store wheel hub rotate a circle the time used LED needed for electric energy, constantly rotate along with wheel and just have the generation of continuous electric energy, achieve as LED continued power.Because the inductor distance nearest with permanent magnetism relative motion is 2mm～5mm, there is no physical friction each other, so just there is no mechanical loss, it is thus possible to be greatly improved the service life of product, only need once mounting, it becomes possible to for LED continued power, feature is: produce electric energy with vehicle wheel rotation for power, as long as vehicle wheel rotation LED is the brightest, the brightest regardless of daytime, it is not necessary to do any operation.
In certain embodiments, described LED string is arranged on the outside of wheel hub, and wherein said outside is that car wheel hub surface in the process of moving is towards pedestrian or the side of other vehicle.
In certain embodiments, hub and/or be installed on the outer hub of wheel hub in described LED string is arranged on the outside of wheel hub and/or is installed on wheel hub.
Running voltage in order to make LED lamp drive circuit be provided to LED string is more stable, and the rectification circuit in this utility model uses bridge rectifier.
Accompanying drawing explanation
Fig. 1 is principle assumption diagram of the present utility model.
