。しかしながら、これら従来の光拡散グローブは種々問
題がある。However, conventional light-diffusing gloves are made by electrostatically coating the inner surface of a glass globe with a white pigment, by suspending a white pigment in water together with a water-soluble resin, or by coating a non-water-soluble resin such as nitrocellulose. Also known are those that are suspended in an organic solvent or water and applied. However, these conventional light diffusing globes have various problems.

水分などの液状物質が付着すると脱落しやすく、また膜
強度が弱いという欠点がある。(Problems to be Solved by the Invention) In the manufacturing method of the light diffusing glove using the electrostatic coating method or the water-soluble resin described above, if liquid substances such as moisture adhere to the inner surface of the glove during the manufacturing process, it tends to fall off. The drawback is that the membrane strength is weak.

をトルエンにけん濁し、この液をガラスグローブ内面に
均一に塗布し、乾燥して光拡散グローブに構成した。(Example) The present inventors used calcium phosphate powder as a pigment on the inner surface of a transparent glass globe for a compact fluorescent lamp.
A light diffusing film was formed by bonding this with a water-insoluble acrylic resin to construct a light diffusing glove. Specifically, the water-insoluble acrylic resin used here is Vinyroll T92, a high-quality product manufactured by Showa Kobunshi Co., Ltd. The content of the acrylic resin in the light diffusion film is 3, 5, 10.25.
It was decided to make a prototype so that each weight% was 50.60. First, the above-mentioned calcium phosphate pigment and acrylic resin were suspended in toluene, and this solution was uniformly applied to the inner surface of a glass globe and dried to form a light-diffusing globe.

第１表に示す。Then, the water resistance of the light diffusion film of this glove was investigated. In the test, the globe was filled with water, the water in the globe was stirred by a stirrer at a rotational speed of 12 Orpm, and the peeling state and appearance of the light diffusing film after 100 hours were inspected. Here, peeling refers to the fact that the light diffusing film is peeled off on the entire surface or locally and the glass surface is exposed, and the appearance means that the light diffusing property is decreased on the entire surface or locally. The test results are shown in Table 1 below.

離せず、また外観良好であった。Table 1 In Table 1 above, the light diffusion film of the electrostatically coated glass globe was almost completely peeled off and almost the entire surface of the glass globe was exposed.
Light diffusivity was completely lost. In addition, when the resin content was 3 wt %, it did not peel off, but the light diffusivity decreased as if water was sprinkled on a frosted glass plate, resulting in the inconvenience of becoming translucent. On the other hand, those with a resin content of 5% it% or more did not peel off at all and had a good appearance.
つぎに、このグローブの光拡散膜の耐候性を調査した。Next, the weather resistance of the light diffusion film of this glove was investigated.

黄変の程度を調査した。この結果を次の第２表に示す。In the test, this light diffusion glove was irradiated with ultraviolet rays from inside the glove using a mercury lamp in a constant temperature bath at 130° C., and the degree of yellowing of the light diffusion film was investigated. The results are shown in Table 2 below.

全く発生せず、良好に機能した。Furthermore, as a practical test, a saddle-shaped fluorescent lamp and necessary electrical components and plastic parts were installed inside this light diffusion globe to form a sealed lighting fixture, and a long-time lighting test at 110V was conducted. According to the test results, when the resin content is 3% by weight, the light diffusivity of the light diffusing film is significantly reduced due to the adhesion of volatile substances such as solvents and resins evaporated from electrical components such as ballasts and plastic parts. and became transparent, making it unsuitable for use. On the other hand, with resin content of 5 to 50 wt%, this does not occur. For example, with resin content of 15% + 1%, the light diffusion film yellows, peels, and decreases in light diffusivity even after being lit for 6000 hours. It worked well without any inconvenience.
