のである。[Detailed description of the invention] This invention relates to a lighting cover made of polycarbonate or other resin, and by providing a small gap at the joint between the cover body and the cap, it is possible to reduce the amount of damage that occurs during processing. It is difficult to visually recognize the strain in the part, and the part is 1 minute away from the joint.
The present invention provides an illumination cover that is irradiated with bright beams of light.
以下、本案を図面に示した実施例について説明すると、

部の上端面３′に一体に溶着したものである。Hereinafter, an example in which the present invention is shown in the drawings will be explained.
1 is a cylindrical cover body with a bottom, and as shown in FIG. 2, the upper end opening is cut out so as to be slightly inwardly inclined by about half of the wall thickness, and is connected to a stepped portion 2 and a joint portion 3. In addition, the inner surface of the joint opening 5 of the cap 4 is inclined to match the slope of the joint part 3, and when welded, the tip 5' is slightly connected to the step part 2. Furthermore, a welded part 6 is provided protrudingly on the lower surface of the soil wall of the cap 4 in correspondence with the upper end surface 3' of the joint part 3, so that the welded part 6 is formed in a length that maintains the interval a. The joint part 3 of the cover main body 1 is inserted into the cover, and the weld part 6 is integrally welded to the upper end surface 3' of the joint part by ultrasonic welding means.
従来、照明用カバーのカバ一本体とキャップとを一体に
接合した場合に、表面に表われる両者の接合線はその太
さ乃至幅が全周面において一定でなければならず、これ
が不規則であると、カバ一本体とキャップとは中心軸線
方向において偏心し又はひずみを有して接合されている
ことが直ちに判別されていた。Conventionally, when the cover body of a lighting cover and the cap are joined together, the joining line between the two on the surface must have a constant thickness or width over the entire circumference, and this is irregular. If so, it was immediately determined that the cover body and the cap were joined together eccentrically or with strain in the direction of the central axis.
本案の照明用カバーは、上記のごとく、カバ一本体の段
部とキャップの接合開口部の先端縁との間にその全周に
わたって隙間が形成されるので、カバ一本体とキャップ
とがその中心軸線方向において多少偏心し又はひずみを
有して一体に溶着されても、これを外観上判別すること
がきわめて困難となり、少しもその外観を損なうことが
ない効果がある。As mentioned above, in the lighting cover of the present invention, a gap is formed over the entire circumference between the step part of the cover body and the tip edge of the joint opening of the cap, so that the cover body and the cap are located at the center of the gap. Even if they are welded together with some eccentricity or distortion in the axial direction, it will be extremely difficult to distinguish this from the appearance, and the effect is that the appearance will not be impaired in the slightest.
また、隙間部分は肉厚が薄いので照明光量も多くなり、
照明光に変化を与えることができる効果がある。In addition, since the wall thickness of the gap is thin, the amount of illumination light increases.
It has the effect of changing the illumination light.
