consists of a straight glass bulb 2 with both ends open L1, and gold 3 (=1) is placed at both ends of the glass bulb 2. , an electrode portion 6 consisting of a filament coil 5 formed on the flare 4 is provided, and connection terminals 7 to be connected to a socket (not shown) or the like are provided on the outer end surface of the base 3, respectively.

れている。Further, a phosphor coating 8 for converting ultraviolet rays into visible light is formed on the inner surface of the glass bulb 2, and the outer surface of the glass bulb 2 is coated with a phosphor film 8 to prevent dew condensation and the like and to increase impedance. A water-repellent silicon coating 9 is formed that facilitates discharge with the conductor and blocks ultraviolet rays.
次に、前記蛍光体被膜８の形成方法について説明する。Next, a method for forming the phosphor film 8 will be explained.

２の一端部と、他端部とては、輝度差を生じやすい。す
なわち、膜厚が厚すぎると、蛍光体被膜８で発生した可
視光が蛍光体被膜８自身に吸収されて輝度が低下する。Before providing the electrode portion 6 on the glass bulb 2, a phosphor suspension in which phosphors emitting blue, green, and red light are mixed in a coating solvent such as nitrocellulose is vertically held at the upper end of the glass bulb 2. After pouring it into the inner surface from one end to coat the entire surface of the glass bulb 2, it is allowed to air dry in that state. At this time, since the glass bulb 2 is held vertically, the suspension is dried while the glass bulb 2 is held vertically.
Since it flows downward along the inner surface, the film thickness at the other end, which is the lower end, is thicker than at one end of the glass bulb 2. and,
When this glass bulb 2 is fired at 550°C, a phosphor/phosphor coating 8 is formed. However, due to the difference in the thickness of the phosphor coating 8, a difference in brightness tends to occur between one end and the other end of the glass bulb 2 while the fluorescent lamp 1 is lit. That is, if the film thickness is too thick, the visible light generated in the phosphor coating 8 will be absorbed by the phosphor coating 8 itself, resulting in a decrease in brightness.
逆に、膜厚が薄いと、発生した可視光の吸収は減少する

する。Conversely, if the film thickness is thin, the absorption of generated visible light is reduced, but the amount of ultraviolet rays converted to visible light is reduced, resulting in lower brightness and ultraviolet rays are irradiated to the outside. Therefore,
The thickness of the phosphor coating 8 that provides high brightness is usually determined by the transmittance or 2
It is said that a film thickness of 0 to 40% is desirable, so
A phosphor coating 8 is formed on the entire surface of the glass bulb 2 to a thickness that satisfies this condition. Therefore, when forming the water-repellent silicone film 9, this difference in film thickness of the phosphor film 8 is taken into account.
前記シリコン被膜９の形成方法について以下に説明する

1% and 79w of butyl acetate as a coating solvent! A coating liquid consisting of 10% of the phosphor W suspension was applied by a flow method to the outer surface of the glass bulb 2, which was held vertically with its lower end reversed from that used when applying the phosphor W suspension. Next, in this state, the temperature is 1
A silicone film 9 is formed by drying at 20° C. for 10 minutes. The silicon coating 9 thus formed is thinnest at the other end of the glass bulb 2, and becomes thicker as it approaches one end of the glass bulb 2.

。Therefore, near one end of the crow bulb 2 where the phosphor wave film 8 is formed thinly, the silicon limb 11 9 is formed thickly. In the vicinity of this one end, since the phosphor wave film 8 is thin, there is a large amount of ultraviolet light that is not converted into visible light and passes through the body arytenoid 8, or is blocked by the thick silicon film 9. The outside of the glass bulb 2 will not be irradiated.

ガラスバルブ２外部に紫外線か照射されることはない。Further, near the other end of the crow bulb 2 where the firefly body wave film 8 is formed thickly, the silicon coating 9 is formed thinly. In the vicinity of this other end, since the phosphor wave film 8 is thick, most of the ultraviolet light is converted into visible light and the fluorescent light 1. The amount of ultraviolet light that passes through the B body 1 film 8 is small. Therefore, even if the silicon coating 9 is thin, it can block the violet I-ray,
The outside of the glass bulb 2 is not irradiated with ultraviolet rays.

It is also possible to form the coating solution by coating the outer surface of the silicon coating 2 on the outer surface of the silicon coating 2 by dipping. With the other end of the bulb 2 on one side, the glass bulb 2 is tilted at an angle of, for example, 30° to 45°.
While tilting the glass bulb 2 and rotating the glass bulb 2 around its longitudinal direction, apply the coating liquid to the glass bulb 2-H at 2M'Fl.
It can also be formed by coating. That is, by tilting the glass bulb 2, the difference in film thickness between one end and the other end of the silicon coating 9 is reduced, and by rotating the glass bulb 2, the coating liquid is thickly coated on the lower surface of the glass bulb 2. Boko is determined to finish first.

As shown in Figure 5, the silicon coating 9 (solid line 1 in the figure) formed by mixing an ultraviolet absorber +0.11 in the method described in ``1'' is thick. As the thickness increases, the ultraviolet absorption rate increases, and a film thickness of 3 μm absorbs 10,096 ultraviolet rays.
