管外面に透明な合成樹脂被膜を形成したものである。BACKGROUND ART Tubes such as fluorescent lamps are mainly composed of glass, and if they are damaged due to improper handling, glass fragments may fly off and cause personal injury. As a method for dealing with this problem, a shatterproof type fluorescent lamp is known in which the outer surface of a glass tube is covered with a transparent synthetic resin tube. This is a tube made of heat-shrinkable polyester resin placed over a glass tube and heated to form a transparent synthetic resin coating on the outer surface of the glass tube.

要で、これはきわめて作業性が悪いという問題があった
。Problems to be Solved by the Invention Conventional shatterproof fluorescent lamps use polyester resin tubes as described above in consideration of weather resistance and membrane strength. However, since this tube is not completely transparent and has a thick film, there was a major problem in that the luminous flux decreased by about 3%. In addition, the tube is extremely tall, and it is necessary to cover the completed fluorescent lamp with a polyester resin tube and heat it in a heating furnace for shrinkage treatment, which is extremely difficult to work with.

After thoroughly mixing 0.2 g of the above materials, the mixture is sprayed onto the outer surface of a 40-watt straight tube white fluorescent lamp held horizontally or vertically. Next, this is dried with warm air at 60° C. and 10 m/sec. After drying, leave it as it is for about 24 hours. In this way, a drop strength test was conducted using a shatterproof fluorescent lamp with a transparent urethane resin coating formed on the outer surface of the glass tube.
Even when the fluorescent lamp was held horizontally and allowed to fall naturally from a height of 3 m, the glass pieces of the fluorescent lamp were adhered to the coating and no pieces were scattered. Furthermore, in an impact test, even when a 100 gram steel ball attached to the end of a 1 m thread was exposed to a lamp at an angle of 30 degrees, the coating remained intact (without tearing).

いことが認められた。Next, as a result of measuring the luminous flux of such a fluorescent lamp, the luminous flux of the lamp before the coating was provided was 32,681 m (0 hours), whereas the luminous flux of the fluorescent lamp according to the present invention was 3,267 m (0 hours).
1 m (0 hours), and furthermore, a lamp using a conventional heat shrink tube (40 watt white fluorescent lamp) is 31
611 m (0 hours), and the lamp according to the present invention was 3% or more brighter. Further, a life test was conducted, and it was found that the product according to the present invention did not turn yellow like the conventional product after being lit for 10,000 hours, and there were no problems.

る。As described in detail, the present invention completely reduces the decrease in luminous flux by forming a transparent urethane resin coating containing polyester polyol and isocyanate as main components on the outer surface of the glass tube.
The material cost is less than one-tenth that of conventional heat-shrinkable tubes, and the coating can be applied efficiently using coating equipment, which significantly reduces manufacturing costs. Therefore, it is possible to provide a shatterproof fluorescent lamp that can significantly reduce the amount of energy used.
