本発明は電球形蛍光ランプのクリア部を有したセミクリ
アンプのガラス管への蛍光体塗布装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an apparatus for applying phosphor to a glass tube of a semi-clear amplifier having a clear section of a compact fluorescent lamp.
従来は発明協会発行の公開技報８４−２１７２号に示さ
れた如くガラス管をフロスト処理することによりセミク
リア化している。しかしながら、フロスト処理作業の安
全衛生面、およびコスト面から蛍光体塗布によるセミク
リア化が望まれているが。Conventionally, glass tubes have been made semi-clear by frosting them as shown in Technical Report No. 84-2172 published by Japan Institute of Invention and Innovation. However, from the safety and health aspects of the frosting process and from the cost perspective, semi-clearing by coating with phosphor is desired.
そのための塗布装置は開発されていない。A coating device for this purpose has not been developed.
本発明の目的は、管球の内面に均一で良好な蛍光体塗布
膜面高さ寸法を一定に塗布することのできる管球の蛍光
体塗布装置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a phosphor coating device for a tube that can coat the inner surface of a tube with a uniform and good phosphor coating film having a constant surface height dimension.
塗布液噴射ノズルからの噴射では塗布膜面高さを約−に

を適当な速度で上昇させながら塗布する方法とすれば、
簡単な構造で均一なる膜面を一定高さで塗布する事が可
能となる。Although it is impossible to achieve a coating film surface height of approximately - by spraying from a coating liquid spray nozzle, it is possible to seal the glass tube and spray nozzle, give a head difference to the coating liquid, and spray the phosphor from the bottom of the glass tube. If you apply it while increasing it at an appropriate speed,
With a simple structure, it is possible to apply a uniform film surface at a constant height.
以下、本発明の実施例を第１，２図により説明する。 Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

フロー筒７よりガラス管４外にオーバーフローする。In the apparatus of this embodiment, a liquid supply pipe 10 is connected to the injection nozzle main body 2 from the lower part of a liquid storage tank 1 storing a certain amount of phosphor coating liquid 5, and a light bulb type fluorescent lamp is held by a clamper 9. Insert the injection nozzle body 2 into the glass tube 4,
With the lower end of the glass tube 4 and the gasket 3 sealed,
By opening the on-off valve 6 in the liquid supply pipe 10 between the liquid storage tank 1 and the injection nozzle body 2, head pressure builds up in the injection nozzle body 2, causing the phosphor coating liquid 5 to rise up the inner surface of the glass tube 4. Apply. When the coating liquid 5 reaches a certain amount or more, it overflows from the overflow tube 7 to the outside of the glass tube 4.
本装置はガラス管４の底から噴射ノズルで塗布液を充填

２との離脱も容易なる塗布装置である。This device fills the coating liquid from the bottom of the glass tube 4 with a spray nozzle, so that the air inside the glass tube 4 is raised by the coating liquid 5 and does not remain as bubbles in the coating liquid 5, and the internal pressure of the glass tube 4 is vented. By opening the pipe 8 to the atmosphere, the film surface becomes uniform, and the overflow pipe 7
By overflowing more, the film surface height can be kept constant. Furthermore, it is a coating device in which the glass tube 4 and the injection nozzle main body 2 can be easily separated.
本発明によれば、膜面高さ精度が１ｍｗ以内にする事が
出来るため、管拭装置による管拭工程を省ける効果があ
る。According to the present invention, since the membrane surface height accuracy can be kept within 1 mw, there is an effect that the tube wiping process using a tube wiping device can be omitted.
