業でチューブを被せ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問題があった。However, this tube is extremely expensive due to the difficulty of tube processing, and the process of manually covering the completed fluorescent lamp with the tube is extremely difficult to work with.For this reason, shatterproof fluorescent lamps are There was a problem in that they 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.

80) Thoroughly stir 185g of the two materials to completely dissolve the polyester polyol urethane. However, in this case, butyl acetate is used to adjust the viscosity. Then,
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 5 m/see to form a transparent film made of polyester polyol type urethane 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 m, the glass tube was broken, but the coating was broken, and the glass pieces were firmly attached to this coating. Therefore, the glass pieces were protected by the coating and nothing was scattered. Next, as a shock resistance test,
Even when a 200 gr steel ball attached to the end of a length of thread was exposed to a fluorescent lamp at an angle of 30 degrees from the vertical line, the coating was not damaged at all.
