平板状にし白熱電球に代替可能なようにした平板
形螢光ランプに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a flat fluorescent lamp, such as a fluorescent lamp, in which the discharge path of a low-pressure gas discharge lamp is bent and meandered so that the external shape is small and flat, so that it can be substituted for an incandescent light bulb. It is related to.
現在一般照明用光源として螢光ランプがその効

選択の広さなどから数多く使用されている。しか
しながら、効率が螢光ランプの1/3〜1/5程度の白
熱電球もまだかなり使用されており、省エネルギ
ー化が強く叫ばれる現在では問題がある。 Currently, fluorescent lamps are widely used as light sources for general illumination due to their high efficiency, low glare similar to that of surface emitting lights, and wide selection of light colors. However, incandescent light bulbs, which have an efficiency of about 1/3 to 1/5 that of fluorescent lamps, are still widely used, which poses a problem at a time when there is a strong demand for energy conservation.
この現象は白熱電球が螢光ランプにない小形高
輝度で片口金の性状を有しているため照明器具の
設計の自由度が大きいこと、点光源に近いため陰
影を混じえたアクセント照明やムード照明を行な
いやすい点などがあるためである。 This phenomenon is due to the fact that incandescent lamps are small, high brightness, and have a single-cap feature that fluorescent lamps do not have, so they have a greater degree of freedom in the design of lighting equipment, and because they are close to point light sources, they can be used for accent lighting with shadows and mood lighting. This is because it is easy to carry out.

不完全な場合には歪によつて弱いランプのガラス
壁が割れたりして量産的に安価に製造できない欠
点があつた。 In order to provide fluorescent lamps with the advantages of incandescent light bulbs, attempts have been made to miniaturize fluorescent lamps, and some have even been put into practical use. For example, a lamp (Jikkosho
36-3972), Utility Model Publication No. 36-27473), and a method of making a small fluorescent lamp by sealing a partition wall inside a disk-shaped luminous tube using glass frits (Utility Model Publication 36-6768). is proposed. However, U-shaped fluorescent lamps are about 1/2 the size of ordinary straight tube lamps.
However, if it is made as small as a light bulb, its brightness and efficiency will decrease. In addition, the method of bending the discharge path by welding partition walls to a disc light-emitting container, etc. is much smaller and brighter than ordinary straight-tube or circular fluorescent lamps, and is easy to manufacture with a single-cap structure, making it an ideal alternative to incandescent light bulbs. Although it is close to ideal as a light lamp, it is very difficult to seal the outer tube wall and the partition wall or between the partition walls, and if the sealing is incomplete, the weak glass wall of the lamp may crack due to distortion. The drawback was that it could not be mass-produced at a low cost.

上側管壁面に反射物質を被着し上側の発光光を下

た。 Furthermore, when a flat fluorescent lamp such as a disk is used with a single-cap end, the efficiency decreases because the light emitted from the upper surface of the lamp is wasted. As an improvement on this, a method has been proposed in which a reflective material is coated on the upper tube wall surface to effectively emit the emitted light from the upper side to the lower side, but this method has the drawback that it takes time and effort to apply the reflective film and increases costs.

を製作することを特徴とするもものである。 This invention was made in view of the above-mentioned circumstances, and provides a bulkhead-shaped flat fluorescent lamp in which a bulkhead is provided in the discharge vessel to bend the discharge path, thereby making the fluorescent lamp compact, high brightness, and with a single base. This attempt was made to solve the difficulties and inefficiencies in mass production caused by the weakness of the glass tube wall with an inexpensive method, and the method involved installing a partition inside the tube and creating a meandering path. A flat fluorescent lamp is manufactured by polymerizing and sealing a flat lid container made of a crystalline ceramic material having good visible light reflection characteristics to an integrally molded dish-shaped glass container. It is something.

To explain the starting device 11 using a glow lamp and the current limiter 10 using a choke coil type ballast, which is the most common example, when the E-shaped cap 9 is screwed into the light bulb socket and the power is turned on, the glow lamp starts. 11 is applied with a power supply voltage of 100 V, a glow discharge occurs, the bimetal pole of the glow lamp 11 operates, and a short circuit occurs, causing two preheating currents determined by the impedance of the Chiyoke coil type ballast 10 and the two electrodes 6. The current flows to the electrode 6, and the electrode 6 is sufficiently heated and thermionic electrons are emitted. Thereafter, the cooled bimetallic pole of the glow lamp 11 is opened, but at this time a high induction voltage is generated between the lamp electrodes 6 by the ballast, so that the lamp 1 is lit.

Further, the flat lid container 4 approximated the thermal expansion coefficient of the glass container 2 made of soda-lime glass. A crystalline forsterite ceramic plate (2MgO.SiO 2 plates) and rosteatite. A ceramic plate (MgO.SiO 2 plate) and three types made of the same material as the glass container were used, and a frit with a similar coefficient of thermal expansion was used to seal them to the glass container. When we investigated the damage caused by temporary distortion caused by the heat treatment process during the production of these lamps and the temperature rise when the lamps were turned on, we found that the flat lid container 4 that used glass had 5.6% damage; It was found that there was no occurrence of this problem in the cases of A and B, in which the steel was used, and the strength was significantly improved.

A lamp was manufactured using the composite ceramic "Makol" in the same manner as in Example 1, and the failure rate was examined. There was no breakage in the case (E) using "Macor", but the breakage rate was 5% for the case (2) using lead glass, and the strength of the case (E) was significantly improved.

Steatite (MgO.SiO 2 ) ceramics A with a reflectance of 23%, steatite ceramics B with a reflectance of 40%, steatite ceramics C with a reflectance of 55%, and steatite ceramics with a reflectance of 70%. A small flat lamp was manufactured using Ceramics D and Steatite Ceramics E with a reflectance of 91%, 2.0 torr of argon as the filler gas, and a normal antimony-added calcium halophosphate phosphor as the phosphor. did. Lamp characteristics: lamp current 320mA, lamp voltage 53V, lamp power
It was 15W and had a lifespan of 6000 hours, and the illuminance directly below the lamp had a relationship as shown in FIG. 5 depending on the reflectance of the flat lid container 4. As can be seen from FIG. 5, when the reflectance of the flat lid container 4 was set to at least 65%, a particularly large improvement in illumination was obtained compared to the case using a transparent glass plate.

In this case, it is necessary to use glass container 2 and flat lid container 4 that have similar coefficients of thermal expansion. Further, although an example has been shown in which the flat lamp 1 and the lighting container 8 are integrated, they may be manufactured separately and used using an appropriate connector.

得られるという効果がある。 As described above, the present invention provides a flat fluorescent lamp in which a partition wall is provided in the discharge vessel, the discharge path is bent, and the fluorescent lamp is small, high-intensity, and has a single base, and the interior is formed by an integral molding method. A glass container with a partition wall and a meandering discharge path is formed by polymerizing and sealing a flat lid container made of crystalline ceramic material, so there is no need to coat the lid container with a reflective film, and workability is improved. This has the effect that the yield during lamp manufacturing is improved and a fluorescent lamp for incandescent lamps suitable for mass production can be obtained.
