商品の照明色を変えることが行われている。In refrigerated showcases, straight tube fluorescent lamps are used for interior lighting, and an air layer is formed between the lamps and the fluorescent lamps to prevent the illumination from becoming abnormal or shortening their lifespan due to cold air. on its outer periphery so that it is -]
The fluorescent lamp is protected by covering it with a transparent cylindrical protective tube that is rounded and supported at both ends by the fluorescent lamp socket. On the other hand, it is desired that the lighting for the products in the warehouse be changed in color depending on the products on display in order to enhance the display effect. For this purpose, a plurality of protective tubes colored in different colors are prepared, and by changing the protective tubes depending on the product, the light of the fluorescent lamp is changed and the illumination color of the product is changed.
ところで蛍光灯の照明色を変えるために保護管を取替え
るには、一端蛍光灯を収り外し保護管を抜き出さねばな
らず、甚だ厄介な作業が伴う。However, in order to change the lighting color of a fluorescent lamp, it is necessary to first remove the fluorescent lamp and pull out the protective tube, which is a very troublesome task.
この発明は、極めて容易に庫内照明色を変えることので
きる冷蔵ジゴーケースの蛍光灯保護管を提供することを
目的とする。An object of the present invention is to provide a fluorescent lamp protection tube for a refrigerated gigo case that allows the interior lighting color to be changed extremely easily.

護骨分回転可能に支持するものとする。In order to achieve the above object, according to the present invention, in a transparent cylindrical fluorescent lamp protection tube that is placed over the outer periphery of a straight tube fluorescent lamp in a refrigerated showcase with an air space in between, this protection tube force is applied. The circumferential surface is divided into a plurality of sections, each section is colored in a different color, or some of the sections are colored, and the protective bone is rotatably supported.
保護管を回転させるだけで異なる色の着色面が庫内側に
向くことにより照明色を変えられる。By simply rotating the protection tube, the colored side of the different color faces towards the inside of the refrigerator, allowing you to change the lighting color.

に回転する。The embodiment of this invention will be explained based on the first (¥1 and second L!!II).In the figure, 1 is a straight tube fluorescent lamp manufactured by T! These are a pair of cycads that have matching current-carrying parts and are connected to a power source via a lead wire 2a. This socket 1-2 has a cylindrical support portion 2b formed on its outer periphery, and is fixed to a side wall or a porcelain inside the refrigerated refrigerator via a mounting member (not shown). 3 is a cylindrical protective tube made of transparent plastic, and its circumferential surface is divided into two in this case, one section 3A has a surface colored red with transparent coloring paint, and the other section 3A has a surface colored red with transparent coloring paint. 3B is similarly colored blue. Furthermore, both ends of the protective tube 3 have sockets 71 to 2.
It fits into the support part 2b with some play and rotates on its outer circumference.

れる。In the above-mentioned 41W configuration, the protective tube 3 placed over the outer circumference of the fluorescent lamp 1 and supported by the cycad 1-2 forms an air layer 4 between it and the fluorescent lamp 1 to remove the fluorescent lamp 1 from the cold air inside the refrigerator. Protect. Further, by rotating the protection tube 3 and directing the compartment 3A or the compartment 3B toward the interior of the refrigerator, the illumination color inside the refrigerator changes to red or blue. In this way, the illumination color can be changed extremely easily.

と同様の効果が得られる。In the embodiment described above, protection 'i! The case where the circumferential surface of No. 3 is divided into two and colored in different colors has been described, but as another example, the circumferential surface may be divided into two and colored in three different colors, or only one section may be colored. It is also possible to illuminate the interior of the refrigerator with the illumination color of the fluorescent lamp 1 as it is, and the same effects as in the above-mentioned embodiments can be obtained.
