易に視認出来る高さに設置される。2. Description of the Related Art Conventionally, an illumination device used as a corner pole or a fender marker for checking the width of an automobile at night is generally configured as shown in FIG. The conventional illuminating device shown in the figure comprises a light source 1 composed of a light emitting diode (LED), a pole 9 and a cap 8 which are formed of a light transmissive resin or the like into a substantially cylindrical shape. The light source 1 is provided at the lower end of the pole 9, the cross section of the pole 9 has a cylindrical curved surface, and the inner wall thickness is formed uniformly. The cap 8 is closely fitted and adhered to the upper end of the pole 9 and has a substantially integral shape with the pole 9. The illuminating device configured in this manner is usually installed at the left end above the front bumper or the left end above the rear bumper of a vehicle at a height that can be easily visually recognized by the driver.

の先の方ほど暗く見える。According to the illuminating device having the above-mentioned configuration, the light emitted from the light source 1 goes straight as shown by an arrow in FIG. Therefore, when the normal driver sees this illuminator from the direction of the arrow a in the figure, the distribution of the light rays is close in the vicinity of the light source 1, and the direction of the light rays and the observation direction (indicated by the arrow a) are almost the same. Because they match, they look very bright and dazzling. However, in a portion far from the light source 1 of the illumination device, the distribution of the light rays becomes sparse, and the driver proceeds to see the traveling direction of the light from the side. For that, Paul 9
It looks darker toward the end.

In the figure, the same components as those in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted. In the figure, a light shielding member 3 made of an opaque metal plate is attached around the pole 9 near the light source 1. When viewed from the direction indicated by the arrow a in the figure, the portion of the pole 9 in the vicinity of the light source 1 is covered with the light shielding member 3 and shielded from light, so that it is not dazzling.

There was a drawback in that the area around was locally dazzling and became darker toward the end of the pole, and the overall brightness was significantly uneven. Further, if a light-shielding member is provided in order to solve the local glare, the brightness of the entire illuminating device is lowered and it is difficult to see, and the commercial value is significantly impaired.

It is possible to prevent local glare without causing a glare. In addition, since the taper is formed so that the diameter of the inner peripheral portion gradually increases toward the tip, the light transmitted through the light transmissive medium is bent outward by the taper of the diameter that gradually changes. And output,
The rod-shaped member emits light to the outside substantially uniformly, and it looks as if the rod-shaped member emitted light uniformly. At the tip, the light-transmissive medium becomes thin and light, so the moment is small. It is possible to reduce the shaking caused by vibration.

効率よく反射するように形成されている。First Embodiment FIG. 1 shows a sectional view of a first embodiment of the present invention. In the figure, the pole 2 is made of a light-transmissive resin, and its outer shape forms a substantially cylindrical shape. The cap 6 is metal-plated and has a large taper formed at the lower end thereof,
It is pressed into and fixed in. A light shielding member 3 made of an opaque metal is attached and covered at the lower end of the pole 2.
The inside of the pole 2 is hollow, and the light source 1 composed of a light emitting diode (LED) is arranged at the lower end. The pole 2 has a cylindrical outer shape, but the inner cavity is integrally molded by a mold into a shape in which the diameter gradually changes. That is, the wall thickness of the pole 2 near the cap 6 is formed to be the thinnest and constant, and then forms a first taper 4 1 toward the center of the cylinder. Then, and again after being formed in the constant thickness, without the second taper 4 2 the cylinder center direction. In this way, the wall thickness of the pole 2 is increased stepwise a total of 6 times,
6 to form a taper 4 1 to 4 6. The taper 4 1 to 4 6
And tapered 4 0 of the cap 6 is formed from the light source 1 to reflect better respective efficiently in the horizontal direction as indicated by an arrow in FIG. 1 the incident light to the tapered surface.

体に一様に明るく視認性の良いものとなる。また、上述
した如く、複数のテーパが一体成形されているために、
少ない部品点数、簡単な構成で、安価に上記の効果が得
られる利点がある。According to the present invention constructed as described above, light incident on the tapered 4 0-4 6 out of the light source 1, in order to taper 4 0-4 6 forms a boundary surface of the resin and the atmosphere, As shown in the figure, the taper surface reflects the light and changes its direction in the horizontal direction. Further, since the pole 2 is shielded by the light blocking member 3 in the vicinity of the light source 1, the pole 2 does not become too dazzling in the vicinity of the light source 1 when viewed from the direction of the arrow a in the figure, and is evenly distributed up to the vicinity of the cap 6. It is bright and has good visibility. Further, as described above, since the plurality of tapers are integrally molded,
There are advantages that the above effects can be obtained at low cost with a small number of parts and a simple configuration.

を確保できる。Further, according to the present embodiment, since the taper is formed so that the diameter of the inner peripheral portion gradually increases toward the tip, the wall thickness of the pole 7 becomes thinner toward the tip, Since the weight is reduced, the moment acting on the pole 7 can be reduced, so that the vibration due to vibration or the like can be reduced, and good visibility can be ensured even when the pole 7 is installed when there are many vibrations or the like.

よい。It should be noted that, in the above-described embodiments, the visibility when viewed from the horizontal direction is changed by changing the light in the horizontal direction by utilizing the reflection or refraction of the incident light from the light source 1 to the tapered surface of the light transmissive medium. Although an example in which the above is improved, the same effect can be obtained by using a curved surface without forming a taper. Also, the shape of the pole is not limited to the cylindrical shape,
It may have a polygonal prism shape, a conical shape, or a polygonal pyramid shape. Further, instead of using the light shielding member, a pole having a very low transmittance may be used in the vicinity of the light source.
Further, the light source may be near the center of the light transmissive rod-shaped member.
