（発明が解決しようとする問題点）しかしながら、一度付者した汚れは容易に取れず、また
、作業も非常に面倒である。(Problems to be Solved by the Invention) However, once the stain is attached, it is not easy to remove it, and the work is very troublesome.

本発明は上記欠点を除去するもので、容易にきれいにで
き、しかも作業が簡単な照明器具を提供することを目的
とする。The present invention eliminates the above-mentioned drawbacks and aims to provide a lighting fixture that is easy to clean and easy to work with.

[Structure of the invention]

（問題点を解決するための手段）本発明は本体の投光開口の周囲に突出片を設けるととも
に、上記突出片に嵌合する係合縁を有する透光性カバー
を上記投光開口に設けたことを特徴とする。(Means for Solving the Problems) The present invention provides a protruding piece around the light emitting opening of the main body, and a translucent cover having an engaging edge that fits into the protruding piece, on the light emitting opening. It is characterized by:

（作　用）透光性カバーは本体に対して、容易に着脱でき、したが
って、別個に用意した透光性カバーを交換することによ
って、投光開口の汚れは容易に除去できる。(Function) The translucent cover can be easily attached to and removed from the main body, and therefore dirt on the light projection opening can be easily removed by replacing the separately prepared translucent cover.

（実施例）以下本発明の詳細を図面を参照して説明する。(Example) The details of the present invention will be explained below with reference to the drawings.

１はランプ２を収納し、投光開口３を有する本体。1 is a main body that houses a lamp 2 and has a light projection opening 3;

４は本体１の投光開口３の周囲に設けられた突出片、５

でもよい。9 is Patsukin. Roughly speaking, 10 is a front frame having an opening 11, and a gasket 12 is interposed between it and the front glass 8. Reference numeral 13 denotes a latch mechanism for holding the front frame 10 around the front surface of the light projection opening 3 of the main body 1. The translucent cover 5 is made of plastic such as polyethylene film, Teflon film, silicone rubber, etc., and may be either soft or hard.

、したがって、清掃作業の安全性は向上する。Next, the operation of the above embodiment will be explained. Translucent cover 5
When the cover becomes dirty, the engaging edge 6 fitted to the protruding piece 4 is removed from the protruding piece 4, and the translucent cover 5 is removed from the main body 1. Next, another similar new translucent cover 5 prepared separately is placed over the front surface of the main body 1, and its engaging edge 6 is fitted into the protruding piece 4. As a result, dirt on the light emitting aperture 3 is removed, and the light from the lamp 2 can be emitted from the light emitting aperture 3 with transmittance close to the initial state. The work is easy because the engaging edge 6 of the translucent cover 5 is simply fitted into or removed from the protruding piece 4 provided on the main body 1, and therefore the safety of the cleaning work is improved.
