Description
【発明の詳細な説明】 産業上の利用分野 本発明は蛍光ランプに関するものである。[Detailed description of the invention] Industrial applications The present invention relates to fluorescent lamps.
従来の技術
蛍光ランプは、効率が高く、かつ任意の光色が得られる
ことから、白熱電球とともに広く使用されている。BACKGROUND OF THE INVENTION Fluorescent lamps are widely used in conjunction with incandescent light bulbs due to their high efficiency and ability to provide any color of light.

の選択やランプコスト、安定した動程特性等の面で難し
い面がある。Problems to be Solved by the Invention Fluorescent lamps can provide any light color depending on the combination of phosphors used, but increasing the color saturation is difficult due to factors such as the selection of phosphors, lamp cost, stable movement characteristics, etc. There are some difficult aspects.
本発明はこのような事情にかんがみてなされたものであ
り、彩度を高めた蛍光ランプを提供するものである。The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a fluorescent lamp with enhanced chroma.
課題を解決するための手段

のである。Means for Solving the Problems The fluorescent lamp of the present invention has a film containing neodymium oxide (N d 20 s ) formed on the outer surface of a glass tube.
作用
本発明によると、蛍光体から放射されたエネルギーが、
酸化ネオジウムの５８ｏｎ−近傍で吸収されることによ
り、蛍光ランプの外側に放射される５８０ｎ■付近のエ
ネルギーが減少するため、彩度を高めることができる。According to the present invention, the energy emitted from the phosphor is
By absorbing neodymium oxide in the vicinity of 58n, the energy in the vicinity of 580n which is emitted to the outside of the fluorescent lamp is reduced, so that the saturation can be increased.
実施例

．５Ｔｏｒｒと水銀３を２５■封入している。Embodiment Embodiment 1 In FIG. 1, the fluorescent lamp according to the embodiment of the present invention has a total length of 58 mm.
The outer diameter is 32.5 mm. Calcium phosphor (Ca+o(PO+)sFCe) is placed on the inner surface of the glass tube 1.
: Sb, Mn)2 is deposited, and argon is placed inside it.
．． 5Torr and 25μ of mercury 3 are sealed.
ガラス管ｌの外面には１．４ｗ／ｃｊの酸化ネオジウム
を含む厚さ０．６園のポリエステルフィルム（ポリエチ
レンテレフタレート）皮膜を形成している。A polyester film (polyethylene terephthalate) coating having a thickness of 0.6 mm and containing 1.4 w/cj of neodymium oxide is formed on the outer surface of the glass tube 1.
上記酸化ネオジウムを含有するポリエステルフィルムの
分光透過率は、第２図に示すとおりである。The spectral transmittance of the polyester film containing neodymium oxide is as shown in FIG.
また、これと比較するために、ガラス管外面にポリエス
テルフィルムを形成しない蛍光ランプも準備した。In addition, for comparison, a fluorescent lamp without a polyester film formed on the outer surface of the glass tube was also prepared.

The spectral distribution of the fluorescent lamp without the polyester film was as shown in FIG. 4, with a color temperature of 4312.

がって、高彩度側にシフトしていることがわかる。As is clear from FIG. 3, it can be seen that in the fluorescent lamp of the example of the present invention, the emitted light in the vicinity of 568 to 589 nm is absorbed by neodymium oxide, and the emitted light intensity is reduced. Therefore, it can be seen that the color has shifted to the high saturation side.

It can be seen that the emission spectrum has decreased and shifted to high saturation.
なお、皮膜の材質としては、上記実施例のほか、ポリウ
