考案されている。It has been conventional practice to attach a plastic heat-insulating tube to a fluorescent lamp used at low temperatures to prevent a decrease in lamp tube wall temperature, or in other words, a decrease in luminous flux. Regarding the mounting structure of the heat insulating tube, see Utility Model Application No. 52-76178.
Various structures have been devised, such as in No. 52-159079.

により達せられる。The above purpose is to use a glass tube made of a material similar to that of a glass tube for a fluorescent lamp to serve as a heat-insulating cylinder, and the end of the fixed part is formed to have dimensions larger than the outside diameter of the glass tube of the fluorescent lamp. This is achieved by fixing the glass tube to the fluorescent lamp using adhesive.

作業性の文中アップとなる。By using a material similar to fluorescent lamp glass for the heat insulating tube, it is inexpensive, has excellent light transmittance, and is durable, while also preventing thermal expansion.
Solve the problem of peeling at the joint surface with the lamp due to shrinkage. In addition, by shaping the heat-insulating glass at the end to a size slightly larger than the outside diameter of the fluorescent lamp glass, it is easier to center the heat-insulating glass when fixing it to the lamp.
The workability will be improved in the text.

ガラス管との間には、約２ｍｍの保温空間５を有する。1 in Figure 1 is a glass tube with an outer diameter of 32.5φ and a length of 580 mm.
It is a 20 watt fluorescent lamp with a cap 2 at both ends. 3 is a heat-insulating glass tube with an outer diameter of 38φ and a length of 562 mm, and the wall thickness is Q, 85 mm. A heat-retaining space 5 of approximately 2 mm is provided between the fluorescent lamp 1 and the heat-retaining glass tube.
保温用ガラス管３の端部４は螢光ランプの口金２とガラ
