Description
【発明の詳細な説明】 産業上の利用分野 本発明は新規な飛散防止形蛍光灯に関する。[Detailed description of the invention] Industrial applications The present invention relates to a novel shatterproof fluorescent lamp.
従来の技術
蛍光灯はガラス管を用いていることから、取り扱いをあ
やまってガラス管を破損させた場合、カラス片が飛散り
人身事故をおこすおそれがある。Since conventional fluorescent lamps use glass tubes, if the glass tubes are damaged due to improper handling, glass fragments may fly off and cause personal injury.

膜を形成したものである。As a method for dealing with this, a so-called shatterproof type fluorescent lamp is known, in which the outer surface of a glass tube is covered with a transparent tube made of a polymer resin such as polyester resin. This is a method in which a glass tube is covered with a layer of heat-shrinkable polyester resin, and then the dupe is heat-treated to form a transparent polymer resin coating on the outer surface of the glass tube.
発明が解決しようとする課題
従来の飛散防止形蛍光灯では耐候性、膜強度等を考慮し
て前記のようにポリエステル樹脂製のチューブが用いら
れている。Problems to be Solved by the Invention In conventional shatterproof fluorescent lamps, tubes made of polyester resin are used in consideration of weather resistance, film strength, etc., as described above.
しかしながら、このチューブはデユープ加工の難しさが

業でチューブを被ぜるという極めて作業性が悪い工程が
不可欠で、そのために飛散防止形蛍光灯は一般形蛍光灯
に比べ極めて高価なものになってしまうという問題があ
った。However, this tube is extremely expensive due to the difficulty of duplex processing, and the process of manually covering the completed fluorescent lamp with the tube, which is extremely difficult to work with, is essential. There was a problem in that the lamps were extremely expensive compared to general fluorescent lamps.
本発明は上記の従来の問題点を解決するためになされた
ものであり、従来に比べ被膜形成が容易で、かつ作業性
のよい飛散防止形蛍光灯を提供するものである。The present invention has been made in order to solve the above-mentioned conventional problems, and provides a shatterproof fluorescent lamp that is easier to form a film than the conventional one and has good workability.
課題を解決するための手段
この目的を達成するために本発明の飛散防止形蛍光灯は
、ガラス管の外面に熱可塑性飽和ポリエステル樹脂から
なる透明な被膜を形成した構成を有している。Means for Solving the Problems To achieve this object, the shatterproof fluorescent lamp of the present invention has a structure in which a transparent coating made of a thermoplastic saturated polyester resin is formed on the outer surface of a glass tube.

光灯に当てても被膜は全く破損しなかった。Example Saturated polyester (manufactured by Toyobo Co., Ltd., Byron-2
00) Thoroughly stir the ingredients of 100 gr and 300 gr of ethyl acetate to completely dissolve the saturated polyester. A straight tube type 40 watt fluorescent lamp held horizontally was immersed in this solution, and then dried with warm air at 70°C and a flow rate of 5 m/sec to form a transparent film made of saturated polyester resin on the outer surface of the glass tube. . Using the thus obtained fluorescent lamp, the following drop strength test was conducted. First, when a fluorescent lamp was held horizontally and allowed to fall naturally from a height of 3 meters, the glass tube was damaged, but the coating was broken, and the glass pieces were firmly attached to the coating. , Therefore, the glass pieces were protected by the coating and there was no scattering. Next, as an impact test, a 200 gr steel ball attached to the end of a 1 m long thread was exposed to a fluorescent lamp at an angle of 30 degrees from the vertical line, but the coating was not damaged at all.

防止形質光灯を提供することができるものである。As described in detail, the present invention forms a transparent coating made of thermoplastic saturated polyester resin on the outer surface of the glass tube, thereby making it extremely easier to form a shatterproof coating on the glass tube than in the past. Furthermore, since the material cost is low, it is possible to provide a shatterproof plasma light lamp that can significantly reduce lamp cost compared to conventional lamps.
