  This has the following problems. On the other hand, good visibility can be obtained while traveling, but it seems that the rotation of the wheel has stopped despite traveling, causing a sense of incongruity when viewed from the surroundings, and when looking instantaneously It was difficult to intuitively grasp the movement of the vehicle. The present invention has been made to solve the above problems.

  A light storage function surface is provided in a ring shape on almost the entire circumference of the wheel rim or tire side surface constituting the wheels of various vehicles, and this light storage function surface is divided and arranged according to the circumferential angle of the wheel for each of two or more luminescent colors, The illumination means for wheels directed in the direction of irradiating light with respect to the phosphorescent functional surface is provided in a portion that does not rotate together with the wheel of the vehicle, and the division angle for dividing each luminous color of the phosphorescent functional surface is an angle obtained by dividing 360 degrees into even numbers And a light storage function surface of the same light emission color arranged at equal angular intervals, position detection means for detecting the angular position of the light storage function surface for each light emission color, and the detection signal of this position detection means on the input side, When a switching circuit in which the wheel illumination means is electrically connected to the output side is provided and the light storage function surfaces are provided on the left and right side surfaces of the wheel, the light emission color of the light storage function surface is symmetrical with respect to the wheel rotation surface. Like A wheel-emitting device, characterized in that the.

  When continuously illuminating light by the wheel illumination means when the vehicle is running, the entire light-storing functional surface provided on the wheel is excited to emit light. By visualizing the rotation of the wheel, it is possible to instantly grasp the rotation state of the wheel from the surroundings even in a dark place. In addition, when light is emitted only to a light-storing functional surface of a specific emission color using the wheel illumination means, a light-emitting part and a non-light-emitting part are generated on the light-storing functional surface, and these rotational movements are visualized. Even in a dark place, it is possible to instantly grasp the rotational state of the wheel from the surroundings. If the wheel illumination means is blinked regardless of the light emission color of the phosphorescent function surface, a plurality of light emission colors are irregularly mixed and the light emission color tone is not stable. However, the present invention also avoids such problems. . In addition, since the same luminous color is arranged at equiangular intervals on the luminous function surface of each luminous color, a stable visual effect that does not cause a sense of incongruity due to the deviation of the luminous color can be obtained. Furthermore, when providing a phosphorescent function surface on both the left and right sides of a wheel in a two-wheeled vehicle, etc., even if the lighting devices for the wheels provided on the left and right of the wheel are turned on at the same timing by using a light emission color symmetrical to the wheel rotation surface The same emission color is obtained on the left and right sides, and there is no sense of discomfort that the left and right emission colors are different.

The phosphorescent functional surface (2) is a surface having a phosphorescent function using a phosphorescent functional pigment that is excited by being irradiated with light from the outside and spontaneously emits light for a certain period of time. The phosphorescent functional surface (2) is divided and arranged according to the circumferential angle of the wheel (1) for two or more colors for each emission color. The two or more luminescent colors referred to here are not only combinations of greatly different color tones such as blue and yellow, green and red, but also combinations of different colors in the same system color, and differences in light and shade due to differences in light emission luminance. Also includes combinations that produce differences. The divisional arrangement by the circumferential angle of the wheel (1) is, for example, as shown in FIG. 1, the division angle (4) is 60 degrees, the luminous function surface (6) of the luminescent color A is green, and the luminous function of the luminescent color B This means that the surface (7) emits blue light and is arranged in a ring shape with green, blue, green, blue, green, and blue. For example, blue, green, yellow, blue, green, and yellow may be blue, green, green, blue, green, and green. The phosphorescent functional surface (2) may be provided, for example, by painting a phosphorescent pigment on the relevant part of the wheel (1), or may be provided by adhering a sheet material provided with a phosphorescent functional layer. The width of the phosphorescent functional surface (2) is preferably within a range that can be easily seen from the side surface direction of the wheel as much as possible and can cover the light irradiated by the wheel illumination means (3) described later. For the wheel oriented in the direction of irradiating light to the phosphorescent functional surface (2) in order to irradiate and excite light around the entire circumference of the phosphorescent functional surface (2) using the rotation of the wheel (1) The illuminating means (3) is fixed to a portion that does not rotate with the vehicle wheel, for example, a body frame, a front fork, a stay, a fender, and the like. As an embodiment, FIG. 2 shows a cross-sectional view of a portion provided with wheel illumination means (3). The light source of the wheel illumination means (3) is preferably one that emits short-wavelength light that easily excites the phosphorescent functional surface (2). The power source of the wheel light emitting device of the present invention may be connected to, for example, a battery provided in a vehicle, or may be separately provided with a dry battery.
(B) As described above, the phosphorescent functional surface (2) is arranged by dividing two or more luminescent colors by the wheel circumferential angle, but the division angle (4) per color is an angle obtained by dividing 360 degrees into even numbers. To do. For example, 45 degrees, 60 degrees, and 90 degrees. At the same time, the phosphorescent functional surfaces (2) having the same luminescent color are provided at equiangular intervals. As a result, a light emitting design with no bias in the light emitting color is obtained, and no uncomfortable feeling is produced when the wheel (1) rotates.
