Description

[Detailed description of the invention] This invention is suitable for illuminating the dial of a main switch for two-wheeled vehicles such as motorcycles, and uses one reflective ring made of a transparent material to disperse and reflect the light from one small bulb. This feature is characterized in that the characters are illuminated.

A few conventional switch lighting devices have been released, but most of them illuminate local areas such as keyholes and letters, and there are also devices that use translucent light guide plates. However, since the light guide plate is flat, its reflection efficiency is poor, and there is no one that has the ability to effectively highlight the various characters provided on the circumference.

This invention uses a thick ring with a certain degree of height to effectively utilize the light from a single small light bulb to effectively highlight the letters placed on the circumference. One embodiment thereof will be described below based on the drawings.

Figure 1 shows a character ring 9 used in the present invention. This character ring has white characters on the back side of a transparent ring, black paint on other parts, and green paint on the back side of the character part. The letters are white during the day, and when illuminated from the back at night, the letters stand out in green.

Figure 2 shows a reflective ring 8 according to the present invention, which has a certain height and is entirely made of transparent acrylic.
It has a notch 5 into which a small light bulb fits, and a linear inclined surface 6 is provided at a position of about 100° to the left, and a step-like inclined surface 7 is provided at a position of about 170° to the right. . This notch 5 is the letter ring in Figure 1.
Located between OFF and ON, both characters are illuminated almost directly by a small light bulb, and the sloped surface 6 illuminates the character LOCK by reflection, and the stepped slope 7
is positioned so that almost the entire area of the word IGNITION is illuminated uniformly by the reflection from the slope of the stairs. The inclined surface provided on this reflective ring 8 is not limited to a linear shape or a stepped shape, but may have any shape. The key is to effectively reflect the light from the bulb and illuminate the desired characters effectively. Therefore, the positions of these inclined surfaces may be appropriately determined depending on the position of the characters on the character ring and the length of the characters.

In the present invention, as shown in FIG. 4, the reflective ring 8 is loaded into a ring-shaped concave groove 3 provided on a concentric circle of a rotor case 2 having a cylinder lock 1 in the center, and the reflective ring 8 is mounted on the upper surface of the reflective ring. A character ring 9 is provided, and a small light bulb 10 is made to face the notch 5 at the lower end of the reflective ring from the lower part of the rotor case.

Therefore, when the small light bulb 10 is turned on at night, the light from the light bulb passes through the transparent reflective ring 8 as shown by the arrows in FIG. This makes the characters located in the area stand out vividly and uniformly in green.

Claims (1)

[Scope of utility model registration request] A ring-shaped concave groove 3 is provided concentrically in the rotor case 2 which has a cylinder lock 1 in the center, and this concave groove has a notch 5 into which a light bulb fits at one place at the lower end of the transparent ring, and is inclined at other appropriate positions. A thick reflective ring 8 having a certain height is fitted by cutting out the surface 6 or the stepped inclined surface 7, and the upper surface of the reflective ring has white letters that can be seen from the surface at all times, and is visible at night. This is a character illumination device for a main switch, which is provided with a character ring 9 in which the characters stand out when illuminated from the back side, and a small light bulb is exposed in the notch 5 of the reflective ring.
