Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a motorcycle lamp used as a tail lamp of a motorcycle.

[Conventional technology]

For example, as shown in FIG. 3, a motorcycle tail lamp is provided with a license lens (clear) 12 on a part of its tail lens (red) 11, and a part of the light emitted from the bulb 13 is used to illuminate the license plate 20.
While irradiating R, R on the 11th surface of the tail lens.
(Reflex reflector) 14 may be attached.

In that case, red miscellaneous light enters the license plate 20 surface due to diffuse reflection from both the inner and outer surfaces of the tail lens 11 to which R and R14 are attached and from R and R14.

Therefore, as shown in Figure 4, (i), R, R14
Paper 15 is placed inside. (ii) Paste the silver tape 16 on the inner surface of the upper part of the tail lens 11. (iii) Countermeasures are taken, such as applying black paint to the inner surface a of the tail lens 11 at the R and R mounting portions.

[Problem that the invention attempts to solve]

However, in the case of (i), with such measures, poor welding may occur due to the placement of the anti-reflection paper 15 within the R and R 14, and workability may be reduced, leading to an increase in costs. In case (ii), pasting the tape 16 not only deteriorates the appearance but also increases costs. In addition, in the case of (iii), the black paint will worsen the feeling when the tail stop is turned on, and the cost will increase.

[Means for solving problems]

In this invention, R and R mounting parts are formed on a part of the front surface of the lens to attach R and R, while a license lens is integrally provided on the license plate side of the lens, and a part of the light emitted from the bulb is attached. In a motorcycle lamp that radiates outward from this license lens to illuminate the license plate,
The present invention is characterized in that prism cuts are provided on both the inner and outer surfaces of the R, R mounting portions to refract the light emitted from the bulb that enters these portions in a direction other than the license plate.

〔Example〕

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

1 and 2 show an embodiment of the present invention, in which 1 is a tail lens (red), 2 is a license lens (clear) provided on a part of the upper surface of the tail lens 1, and 3 is the above-mentioned license lens (clear). A bulb is mounted inside the tail lens 1, 4 is R, R, and 20 is a license plate. An R and R attachment part 5 is formed in a part of the upper half of the front surface of the tail lens 1, and R and R4 are welded to this part by ultrasonic welding or the like. The R, R mounting portion 5 has prism cuts 5A, 5B on both its inner and outer surfaces so that the direction of light incident thereon is other than the direction toward the license plate 20.

With this structure, part of the light emitted from the bulb 3 is irradiated onto the license plate 20 through the license lens 2. In this case, valve 3
The light that has entered the R, R mounting portion 5 from the R, R mounting portion 5 is radiated in a predetermined direction (a direction excluding the direction of the license plate 20) by the prism cuts 5A and 5B as shown in FIG. The incidence of red light on top becomes extremely low.

[Effect of idea]

As described above, according to the present invention, since prism cuts are provided on both the inside and outside of the R and R mounting parts to specify the direction of light travel, it is possible to significantly reduce the stray light (red light) that enters the license plate. I can do it. Furthermore, since there is no need for pasting tape or paper or painting, there are advantages in that the appearance is good and costs can be reduced.
