Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp called a combination lamp.

<Prior Art> As a conventional vehicle lamp, a plurality of curved refracting surface portions are formed on one side surface in a state of being aligned in at least one direction in a housing including a plurality of valve-equipped compartments formed by partition walls. It is known that a known fish-eye lens body for light diffusion is assembled (see Japanese Utility Model Laid-Open No. 60-192307).

<Problems to be Solved by the Invention> However, in such a conventional technique, since each curved refracting surface portion of the fish-eye lens body plays a role like a convex lens, the fish-eye lens body and the partition wall Depending on the positional relationship, the tip portion may be enlarged, and the presence of the partition wall may be visually recognized from the outside.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a vehicular lamp in which a partition wall is invisible from the outside through a lens.

<Means for Solving the Problem> The vehicle lamp according to the present invention, in order to achieve the above-mentioned object, the tip of the partition wall is sharpened, and all the tips of the tip are made of a fisheye lens body. The straight boundary line between the curved refracting surface portions along the alignment direction is closely matched. Here, the “aligned state” means that the boundary lines of the curved refracting surface portions are arranged in a straight line.

<Operation> If the tip of the partition wall tip is made to match the boundary line between the curved refracting surfaces along the alignment direction of the fisheye lens body, the tip will not be enlarged in each curved refracting surface, making it difficult to see from the outside. .

<Embodiment> A preferred embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 is a combination lamp as a "vehicle lamp", which is arranged at both sides of the rear part of the automobile. Reference numeral 2 denotes a housing, inside which three compartments 3 arranged in the lateral direction A are formed by two partition walls 4 along the longitudinal direction B. Each of the compartments 4 is provided with one bulb 5 and is lit according to an instruction from an electric control circuit (not shown). Reference numeral 6 is a fish-eye lens body, and in order to diffuse the light emitted from the bulb 5, a plurality of curved refracting surface portions 7 are formed in a vertical / horizontal alignment state on the surface on the bulb 5 side. Then, the tip portion 8 of the partition wall 4 prevents the light from the adjacent compartments 3 from entering each other.
It is in a state of being close to the fisheye lens body 6. Therefore, in order to make the presence of the partition wall 4 as invisible as possible from the outside through the fish-eye lens body 6, the tip portion 8 of the partition wall 4 has an acute angle that is obliquely cut as a measure against appearance, and this sharp angle is also provided. All of the tips 9 of the tip 8 are aligned with the linear boundary line 10 in the longitudinal direction between the curved refracting surface portions 7 aligned with each other. Therefore, the tip 9 does not have to be enlarged by the individual curved refracting surface portions 7, and the partition wall 4 becomes difficult to see from the outside.

In the above description, the curved refraction surface portions aligned in both the vertical and horizontal directions are taken as an example, but the curved refraction surface portions may be aligned at least in the direction along the partition wall.

<Effects of the Invention> The vehicular lamp according to the present invention has the contents as described above, in which the tip of the partition wall is sharpened and all the tips of the tip are aligned with the fisheye lens body. The linear boundaries between the curved refracting surfaces along the direction are closely matched to each other, so that the tips are not enlarged in the individual curved refracting surfaces, and the partition wall itself becomes difficult to see from the outside. , The overall appearance of vehicle lighting is improved.
