Description

[0001]
The present invention relates to a two-wheeled vehicle wheel light-emitting device that emits ultraviolet light to a phosphorescent functional part provided on a wheel rim of a wheel in a motorcycle by ultraviolet illuminating means so that the luminous part of the wheel rim always emits light with high brightness during night driving. It is about.
[0002]
[Prior art]
Conventionally, as a wheel light emitting means for two-wheeled vehicles to improve nighttime vehicle visibility and fashionability, a reflector is attached to the spoke, a fluorescent sticker is attached to the wheel rim, or a sticker having a phosphorescent function is attached. There was a means of.
[0003]
[Problems to be solved by the invention]
These have the following drawbacks. Reflectors and fluorescent stickers are conspicuous by reflecting light only when exposed to light from the outside, and did not function in places where no external light was applied. Also, seals with a phosphorescent function do not emit light if they are not exposed to light for a certain period of time, and because the time for which sufficient brightness lasts is short, they function effectively when entering a tunnel from a bright place. And so on. The present invention has been made to eliminate these drawbacks.
[0004]
The wheel rim (3) of a motorcycle wheel is provided with a phosphorescent functional part (2), and the ultraviolet illuminating means (1) for irradiating ultraviolet rays toward the wheel rim (3) is adjacent to the wheel rim (3) and does not rotate with the wheel. By providing it, it is possible to repeat the re-irradiation of ultraviolet rays to the luminous function part (2) at any angle of the entire circumference when the wheel rotates, and the luminous function part (2) emits light with high brightness while traveling So that they can continue The present invention is a wheel light emitting device for a motorcycle having the above-described configuration.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. First, a phosphorescent function is added to the wheel rim (3) of the wheel provided in the motorcycle. The wheel may be a front wheel or a rear wheel. The positions to be added are desirably left and right side surfaces that have a large effect of improving visibility. For example, a phosphorescent function seal is applied to the wheel rim (3), or a phosphorescent function paint is applied to the wheel rim (3). The phosphorescent seal and phosphorescent coating itself are not described in the scope of the present invention but are described in detail in the respective inventions, and since they are already commercially available, they are not described here.
[0006]
Next, the ultraviolet illuminating means (1) capable of irradiating ultraviolet rays is attached to the two-wheeled vehicle provided with the luminous function part (2) on the wheel rim (3) of the wheel. The ultraviolet illuminating means (1) referred to in the present invention is an illuminating means for irradiating light containing strong ultraviolet rays, and does not mean that the irradiated light should not contain visible light. For the light source of the ultraviolet illuminating means (1), a purple (ultraviolet) light emitting diode which is strong against impact and has a small current consumption is suitable.
[0007]
The ultraviolet illuminating means (1) is attached to a portion adjacent to the wheel rim (3) and not rotating with the wheel, that is, a fender, a fender fixing stay, a front fork, a suspension fork, a vehicle body frame and the like. The attachment means (4) may be a belt, a metal fitting, a double-sided adhesive tape, or the like, but means that does not easily move the ultraviolet irradiation direction of the ultraviolet irradiation means (1). The irradiation direction of the ultraviolet illuminating means (1) is directed to the luminous function part (2) provided in the wheel rim (3). It is desirable that the distance from the phosphorescent functional part (2) of the ultraviolet illuminating means (1) is a non-contact distance and is attached as close as possible. This is to suppress the diffusion of ultraviolet rays as much as possible to enhance the luminous effect of the phosphorescent functional part (2), and to prevent the rubber of the tire (5) from being deteriorated by the diffused ultraviolet light. It is also for the purpose. The light irradiation direction of the ultraviolet illuminating means (1) is directed to the phosphorescent functional part (2). At least one UV illumination means (1) is attached to one side of the wheel rim (3). By rotating the wheels during traveling, it is possible to irradiate the entire wheel rim (3). For this reason, you may provide the luminous function part (2) provided in a wheel rim (3) in any angle. It may also be provided all around.
[0008]
The power source of the ultraviolet illumination means (1) may be supplied from a power generator provided in the motorcycle or a battery, or a separate power source such as a dry cell may be used exclusively. FIG. 5 shows a circuit diagram of an embodiment of the present invention when a battery is used for a bicycle. The purple (ultraviolet) light emitting diodes (LED1, LED2, LED3, LED4) start to emit light automatically by using the battery (BT) as the power source according to the power generation current of the headlight generator (G). It irradiates a site | part (2). The reason why four purple (ultraviolet) light emitting diodes are provided is to provide one each on the left and right of the front wheel and one on each of the left and right of the rear wheel. A photorelay (U1) is used to detect the generated current. The diodes (D1, D2, D3, D4) are for rectifying the detection current, the fixed resistor (R1) and capacitor (C1) are for voltage smoothing, and the constant voltage diode (ZD1) is for overvoltage protection of the photorelay (U1). is there.
[0009]
With the above mechanism, the wheels rotate while traveling, so that the ultraviolet light is repeatedly irradiated to the phosphorescent functional parts (2) arranged all around the wheel rim (3). The reason why the high-luminance emission can be sustained will be described with reference to the graphs of the luminous characteristics 1 (FIG. 3) of the phosphorescent material and the luminous characteristics 2 (FIG. 4) of the phosphorescent material. Normally, when the phosphorescent material is irradiated temporarily for a certain period of time and left to stand, as shown in Fig. 3, it emits light with high luminance during irradiation, but it emits light with the passage of time immediately after the ultraviolet irradiation is stopped. Luminance decreases and weak light emission lasts for a while. In the case of the present invention, as shown in FIG. 4, in the process of reducing the emission luminance, the ultraviolet rays are re-irradiated by the rotation of the wheel while the high luminance is still maintained. It is kept. Increasing the number of ultraviolet light emitting means (1) attached on one side of the wheel increases the light emission luminance of the phosphorescent functional part (2) to a certain level. In addition, when mounting a plurality of light sources, if they are mounted at different angles, the time interval until the ultraviolet rays are re-irradiated is shortened, and the light emission luminance can be increased efficiently. In the embodiment of FIG. 1, the present invention is attached to both the left and right sides of the wheel. However, when the light is emitted by a generator when attached to a bicycle, the current supply capacity of the generator is limited, so only one of the left and right sides is used. It can be installed. At this time, it is desirable to install on the right side in consideration of left-hand traffic.
