この発明は照明器具のグローブやセード醇の透光カバー
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a light-transmitting cover for a glove or shade for a lighting device.
従来、乳白色のグローブでは、第６図（６）に示すよう
に、グローブ５の壁部の肉厚に対して均一に乳白の添加
剤６が入っているが、添加剤の密度が淡いため、外から
見えたときに、真白のグローブに見えず、ぼけた半透明
な白色に見える。真白なグローブに見せるために、第６
図の）のように、添加剤６の密度を増すと、透過率が悪
くなってしまう。さらに改良して、透過率を上げるため
に、第６図（Ｃ）のように、グローブ５の厚みを薄くす
ると、はっきりとした白色に見え、しかも透過率も良い
が、強度的に問題が生じる。Conventionally, in the case of a milky white glove, the milky white additive 6 is uniformly contained in the wall thickness of the glove 5, as shown in FIG. 6 (6), but since the density of the additive is low, When viewed from the outside, it does not look like a pure white glove, but rather a blurry, translucent white color. To make it look like a pure white glove, the sixth
As shown in ) in the figure, when the density of the additive 6 is increased, the transmittance deteriorates. In order to further improve the transmittance and make the thickness of the globe 5 thinner as shown in FIG. 6(C), it looks clear white and has good transmittance, but a problem arises in terms of strength. .
第７図のように、透明板７の外側に白色の塗膜８を塗装
したものは、外から見ると透過率もよく、かつ強度的に
も強いが、塗膜がはがれたシするという問題がある。As shown in Fig. 7, a transparent plate 7 with a white paint film 8 painted on the outside has good transmittance and strong strength when viewed from the outside, but the problem is that the paint film peels off. There is.
また、場所によって厚みの異なるグローブの場合、第８
図のように添加剤６を均一に混入したものでは、透過率
が異なり、グローブ５の外面に輝度むらが発生する。In addition, in the case of gloves with different thickness depending on the location,
If the additive 6 is uniformly mixed as shown in the figure, the transmittance will be different and uneven brightness will occur on the outer surface of the globe 5.
また、従来、プリズムパネルからなる透光カバーでは、
無色透明の材料で作らｎていることが多いが、その場合
、内部のランプイメージが著しかっ九り、パネル面上の
輝度比が大きかったりする問題が生じることがある。こ
の問題を防ぐ方法としては、従来、パネル全体に乳白の
添加剤を入れる方法がある。しかし、パネル全体に乳白
の添加剤をい□ると、７．あア中。鼠、ゆる所ア光、１
拡散し、そのため光学的に優ｎたプリズムパネルを作る
ことができない。In addition, conventionally, transparent covers made of prism panels,
They are often made of a colorless and transparent material, but in that case, problems may occur, such as the internal lamp image being extremely sharp and the brightness ratio on the panel surface being large. A conventional method to prevent this problem is to include an opalescent additive throughout the panel. However, if you apply a milky white additive to the entire panel, 7. Ah middle school. Mouse, Yurudokoro Ako, 1
It is difficult to make optically superior prism panels.
この発明は、光の透過性と外観に優ｎ５かつ強度的にも
優ｎた照明器具の透光カバーを提供することを目的とす
る。An object of the present invention is to provide a light-transmitting cover for a lighting device that has excellent light transmittance and appearance, and is also excellent in strength.
この発明の照明器具の透光カバーは、透明樹脂板と色付
き樹脂板とを重ねて熱融着させた２層構造としたもので
ある。The light-transmitting cover of the lighting equipment of the present invention has a two-layer structure in which a transparent resin plate and a colored resin plate are stacked and heat-sealed.
そのため、色付き樹脂板を添加物の多い外観の優れたも
のとしても、強度上の問題を生じることなく肉厚を薄く
して光の透過率を向上させることができる。また、２枚
の板を熱融着させたものであるから、塗装したものと異
なり、はがれ等の問題が生じない。Therefore, even if the colored resin plate contains many additives and has an excellent appearance, the thickness can be reduced and the light transmittance can be improved without causing problems in terms of strength. Furthermore, since it is made by heat-sealing two plates, unlike painted plates, problems such as peeling do not occur.
実施例
この発明の一実施例を第１図ないし第３図に示す。すな
わち、この照明器具の透光カバーは、無色透明の透明樹
脂板１と、色付き樹脂板２とを重ねて熱＃ｊＩＷしたも
のである。色付き樹脂板２は添加剤濃度が濃く肉厚の薄
い乳白色のものを用いている。熱融着は、第２図のよう
に、加熱された透明樹脂板１と色付き樹脂板２とを、加
熱状態の金型３．４で加圧して行なう。この透光カバー
は、グローブまたはセードとして成形したものであり、
加熱融着時に金型３．４で湾曲成形を同時に行なう。Embodiment An embodiment of the present invention is shown in FIGS. 1 to 3. That is, the light-transmitting cover of this lighting fixture is made by overlapping a colorless transparent resin plate 1 and a colored resin plate 2 and heating them #jIW. The colored resin plate 2 is a milky-white one with a high concentration of additives and a thin wall. Heat fusion is performed by pressing the heated transparent resin plate 1 and colored resin plate 2 together using a heated mold 3.4, as shown in FIG. This transparent cover is molded as a glove or shade,
Curved molding is simultaneously performed using mold 3.4 during heat fusion.
このように構成したため、外から見たときは、添加剤濃
度の濃い乳白色の色付き樹脂板２が見え、真白の透光カ
バーに見える。そのため外観が良い。With this configuration, when viewed from the outside, the milky white colored resin plate 2 with a high concentration of additives can be seen, and it looks like a pure white transparent cover. Therefore, the appearance is good.
色付き樹脂板２の厚さは薄いため、中からの光の透過率
は悪くならない。また、透明樹脂板１の厚みは充分に厚
くできるので、強度的に問題がない。Since the colored resin plate 2 is thin, the transmittance of light from inside does not deteriorate. Further, since the thickness of the transparent resin plate 1 can be made sufficiently thick, there is no problem in terms of strength.
オた、透明樹脂板１と色付き樹脂板２と線熱融着するの
で、色付き樹脂板２がはがれる心配がない。Additionally, since the transparent resin plate 1 and the colored resin plate 2 are wire-heat fused, there is no fear that the colored resin plate 2 will peel off.
第４図は他の５ｉ！施例を示す。この例は透明樹脂板１
′の肉厚を部分的に変化させたものである。このように
透光カバーの厚みを部分的に変化させても、色付き樹脂
板２は厚みを均一とできるため、透光カバー全体にわた
ｐ１透過率を一定とすることができる。そのため、輝度
むらが発生しない。Figure 4 shows other 5i! An example is shown. In this example, transparent resin plate 1
The wall thickness of ′ is partially changed. Even if the thickness of the light-transmitting cover is partially changed in this manner, the thickness of the colored resin plate 2 can be made uniform, so that the p1 transmittance can be made constant over the entire light-transmitting cover. Therefore, uneven brightness does not occur.
その他は第１の実砲例と同様である。The rest is the same as the first actual gun example.
第５図はさらに他の実施例を示す。この例は、プリズム

ら出九光は、その外側の透明なプリズム板１′を通り、
空気との界面を通って室内に出る。ここでは光拡散は起
こらないので、拡散光を良好にコントロールできる。FIG. 5 shows yet another embodiment. In this example, the prism panel 1' is made of a transparent resin plate, and a thin milky white colored resin plate 2 is provided on the inner surface of the prism panel 1'. This milky white colored resin plate 2 can diffuse the light from the land 3 and erase the lamp image. Also, the nine lights coming out of this diffusion part pass through the transparent prism plate 1' on the outside,
It exits the room through the interface with the air. Since no light diffusion occurs here, the diffused light can be well controlled.
その他は第１のｖｍ例と同様である。The rest is the same as the first VM example.
なお、前記各実施例では色付き樹脂板２を乳白色とした
が、他の色としてもよい。In each of the above embodiments, the colored resin plate 2 was made milky white, but it may be made of other colors.
