Abstract

PURPOSE:To make it possible to observe a design expressed on a tire wheel as this design stops, during running at night, by setting a stroboscopic light emitting device adapted to emit light synchronously with the rotating speed of the wheel, on the fender part at the wheel position. CONSTITUTION:A permanent magnet m is fixed by adhesive on the inside surface of a wheel H, and a detecting coil c of a detecting part D1 is fixed to a knuckle A, by the position which the magnet m passes with the rotary motion of the wheel H. A stroboscope S is fixed by a machine screw, on the fender part F which is correspondent with the wheel position, at the position as this stroboscope S lightens up the outside face of the wheel. Then, light is emitted intermittently from a xenon lamp L synchronously with the wheel, by giving pulse current which is synchronous with the rotation of the wheel, from the coil c to a trigger of the stroboscope S, during running at night. That is, a design on the outside face of the tire wheel is lightened up always at the set phase condition, by emitting light from the lamp L always at the set phase position of the wheel.

Description

Detailed Description of the Invention 10 Objects of the Invention [Field of Industrial Application] The present invention relates to an illumination device for the wheels of an automobile while driving at night, and more specifically, a lighting system for illuminating the wheels of an automobile while driving at night. [This is a lighting device characterized by providing a 1-bore light emitting device.

[Conventional technology]

As automobiles become more popular, users are becoming more and more individualized, and there is a trend for automobiles to be decorated in unique ways, such as with unique paint or unique accessories.

One of these trends is that relatively expensive tires and wheels with unique designs have come to be used.

However, conventionally, no consideration has been given to illuminating such wheel portions, and therefore, wheel illumination devices such as the present invention have not been manufactured or used at all.

[Problem that the invention seeks to solve]

With the rise of luxury 1, a wide variety of tire and wheel designs are being offered as individualization progresses, but no matter how elaborate the design is, it is usually difficult to recognize visually due to the rotational movement of the wheels while the car is running. I couldn't do it. However, for users, having others recognize the design of the tires and wheels they are wearing means realizing their individualization, and even when the car is running, the desire for this is It existed quite latently.

[Means for solving problems]

The present invention provides a wheel lighting device that meets the above requirements, and is characterized in that a strobe light emitting device that emits light in synchronization with the rotation of the wheel is provided in a part of the hood at the wheel position. The rotation of the wheel is detected by magnetism or light, and the detection signal is sent to the strobe light emitting device to adjust the cycle of the wheel rotation and strobe light emission.
As a result, the tire wheels are always illuminated with pulsed light emission in the same phase, so the design expressed on the tire wheels can be recognized even when the vehicle is stationary while driving at night. .

[Effect]

The electrical system related to the lighting device of the present invention is shown in the block diagram of FIG. It consists of three parts: a strobe part S that causes the arc tube to emit light, and a detection part that provides a wheel rotation signal to the trigger of the strobe part S.

The illumination device of the present invention is comprised of a strobe section S and a detection section surrounded by dotted lines among the three parts mentioned above.

Electric V! Part E usually uses the own VJ vehicle's power supply.

The strobe unit S is manufactured by changing the shape and dimensions of a normal strobe light emitting device to suit the usage conditions of the present invention, and is attached and fixed to the fender part corresponding to the position of the wheel. Ru.

The detection section detects the rotation of the wheel using magnetism or light, and a detection object is fixed to a fixed position on the inner or outer side of the wheel, and the rotation is detected by the detection object.

In the case of a detection unit that uses magnetism, a permanent magnet or
When a coil is used as the detection object and light is used, a coil is used as the detection object, and a light emitting element and a light receiving element consisting of a photodiode are used as the detection object.

〔Example〕

Hereinafter, a first embodiment in which a magnetic detection section D2 is provided on the inner surface of the wheel, and a first embodiment in which a detection section D2 using light is provided on the outer surface of the wheel ff.
A second embodiment provided in 1l will be described with reference to the drawings.

FIG. 2 is an explanatory longitudinal cross-sectional view of a first embodiment in which a detection section using a magnet is provided on the inner surface of a front wheel of an automobile.

One permanent stone plate is fixed to the inner surface of the wheel H with adhesive. The detection body d, the roar detection coil C, has a magnet that rotates as the wheel rotates, and the strobe part S is fixed with screws to the fender 1 part corresponding to the wheel position in a position that efficiently illuminates the outer surface of the wheel. has been done. 12V DC is supplied to the strobe part S from the cigarette lighter insertion part.
The power is supplied, the voltage is stepped up and the voltage of 10,000V is stored in the capacitor. On the other hand, the coil C is connected to the trigger of the strobe part S, and the trigger discharges the capacitor when a pulse current of a voltage higher than a certain level is applied from the coil C, and the xenon lamp L is 1/60
It emits light for about 00 seconds.

In the lighting device having the above-mentioned configuration, when the car is running, a pulse current synchronized with the rotation of the wheels is applied to the coil C.
is given to the trigger of the strobe unit S, and therefore the xenon lamp L emits light intermittently in synchronization with the wheel rotation. That is, since the lamp always emits light at a constant phase position of the wheel, the design on the outer surface of the tire wheel is always illuminated at a constant phase. Therefore, the human eye can observe the tire wheel in a stationary state, so that the design can be recognized as vX.

3 and 4 are an explanatory longitudinal cross-sectional view and a side view showing a second embodiment in which the optical detection section D2 is provided on the outer surface side of the rear wheel of an automobile, and shows a mirror l' of the object to be detected. are fixed to the outer surface of the wheel in three parallel directions in the same phase direction. The detector d2 and the strobe part S are integrally fixed to the fender 1, and the tip of the detector d2 is a mirror m'.
is located near the rotation passage and extends downward.

A light emitting element p1 is provided at the base of the detection body d2, and a glass fiber 9 that guides and irradiates light from the light emitting element p to the outer surface of the wheel extends downward, and has a tip end that emits light reflected from the mirror m'. The light receiving element p2 to be captured is provided so as to face the mirror m' in parallel. The # end of the glass fiber 9 is provided so as to cover the outer periphery of the light receiving element p2 and radiate light in the direction of the mirror 1.

The signal from the light-receiving element p is amplified by a suitable amplifier and inputted to the input terminal of the strobe section S.

Then, strobe light is emitted by the same operating mechanism as in the first embodiment, and the object of the present invention is achieved.

In this embodiment, since the detection object d2 is fixed to the fender part, the mirror l' which is the detected object fixed to the wheel.
The mirrors 1 are arranged in parallel in the circumferential phase direction, that is, in the diametrical direction of the wheel, within the range of the change, since the relative position of the mirrors 1 to the wheel changes due to perturbations of the vehicle, especially vertical vibrations.

Further, in order to avoid erroneously detecting the reflected light from the wheel itself, it is necessary to provide the mirror l' at a sufficient angle with the outer surface of the wheel.

It should be noted that it is not preferable to provide the detection body on the fender portion of the front wheels, which change direction as the vehicle turns left or right, as in the second embodiment.

In the above two embodiments, the object to be detected was provided in one phase part, but the object to be detected was provided at a position that equally divided the wheel.
Multiple light emissions may be obtained for each wheel rotation.

Effects of the Invention As described above, according to the present invention, it is possible to recognize the design of tires and wheels of automobiles driving at night. By applying unique designs such as letters and figures to wheels and tires and using the wheel lighting device of the present invention,
It is now possible for others to recognize and appreciate the design expression while driving, further satisfying the sense of fun in car life. The wheel surface can also be used for nighttime advertising.
