Illuminating device on vehicle wheels

Abstract

The invention provides an illuminator used on wheels of vehicles. The illuminator comprises a frame, at least a magnetic inductive coil, an illuminating component, a rotational component and at least a magnetic component. The frame is arranged at the position deviated from the wheel center on the wheels, and a solid rotational center is provided; the magnetic inductive coils all cross over the frame and wind around the frame; the illuminating component is electrically connected with the magnetic inductive coil; the rotational component can be fixed on the rotational center of the frame rotationally; the magnetic component is fixed on the rotational component. When the vehicles are traveling, the illuminating device conducts the rotational movement relative to the center of the wheels so that the magnetic component conducts the rotational movement relative to the rotational center of the frame along with the rotational component, thus generating the inductive coil produce inductive current and providing for the illuminating component to make the illuminating component illuminate.

Description

technical field [0001] The invention relates to a light emitting device, in particular to a light emitting device applied to vehicle wheels. Background technique [0002] Most of the wheels of general vehicles are not equipped with light-emitting devices that can provide warning functions, so that the driver cannot be alerted by other drivers on the road when driving at night or when the vision is poor, which will cause a certain degree of danger to the driver. sex. In view of this situation, most manufacturers only add reflectors or reflective strips to the wheels of the vehicle. This type of reflective sheet or reflective strip must be irradiated by an external light source to be able to play a warning role. However, at night or when the line of sight is poor, this type of reflective device will not be effective, and the safety effect will be greatly reduced. This shortcoming has always been a common complaint. [0003] In addition, China Taiwan Patent Publication No. 4...

Problems solved by technology

[0005] For the light-emitting device mentioned above, there are two main disadvantages: first, it needs the swing of a heavy weight to drive the magnet to swing the permanent magnet coil, thereby generating electric energy

In the magnetic energy conversion effect, only the relative movement of the magnet to the coil is needed to generate power generation, and an additional and heavy weight is not required to drive the magnet. Therefore, the above-mentioned weight not only increases the complexity of the device, but also extra unnecessary cost

Second, in the magnetic energy conversion effect, according to Lenz’s law, the induced electromotive force is equal to the number of coil turns multiplied by the rate of change of the magnetic flux of the coil. Simply put, the amount of electricity generated can be regarded as the number of coils multiplied by the moving rate of the magnet. Therefore, only the swing effect is generated by the magnet and the permanent magnet coil. In the case of such a low moving speed of the magnet, the generation of electric energy is bound to be insufficient.
