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.

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.

ないやすい点などがあるためである。 This phenomenon is caused by the fact that incandescent bulbs are smaller than fluorescent lamps.
This is because it has high brightness and has a single-cap feature, which allows a great deal of freedom in the design of lighting equipment, and because it is close to a point light source, it is easy to use for accent lighting with shadows or mood lighting.

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 sealingly welding a partition wall into a disk-shaped arc tube using glass frits (Utility Model Number 36-6768). 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 welding a partition wall to a circular wall light-emitting container and bending the discharge path can be used as an alternative to incandescent light bulbs because it is much smaller, has higher brightness, and is easier to make with a single-cap structure compared to ordinary straight tube or circular fluorescent lamps. Although it is close to ideal for a fluorescent lamp, it is very difficult to seal the outer tube wall and the partition wall or to seal the partition walls together, 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 low cost.

タなどの使用が考えられていた。 In addition, when a flat fluorescent lamp such as a disc is used with a single cap, the lamp emits light from the upper surface and the light emitted from the upper surface is wasted, resulting in a reduction in efficiency. 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 light emitted from the upper side to the lower side, but this method has the drawback that it takes time and effort to coat the reflective film and increases costs. In addition, since the lamp is used in place of an incandescent light bulb, it is required that the lamp be lit in an instant. However, in order to obtain instantaneous flashing properties, it is necessary to impart conductivity to the lamp wall, but due to the complicated structure of the lamp, it is not possible to manufacture it at low cost, and it is unavoidable to use expensive electronic starters. was considered for use.

る。 This invention was made in view of the above-mentioned circumstances, and provides a partition-shaped flat fluorescent lamp in which a partition is provided in the discharge vessel and the discharge path is bent, thereby making the fluorescent lamp compact, high brightness, and with a single base. This was an attempt to solve the difficulty and inefficiency of mass production caused by the weakness of the glass tube wall, as well as the difficulty in making starting auxiliary conductors, with an inexpensive method. A flat fluorescent lamp is manufactured by polymerizing and sealing a flat lid container made of a metal material having good reflection characteristics of visible light to an integrally molded dish-shaped glass container having a meandering path. That is.

である。 The lamp constructed in this way has a lighting container 8 having an E-shaped cap 9, which is the same as an incandescent light bulb, and a lamp 1 that are integrated, and have a structure that can be used by screwing into a normal light bulb socket. To explain the starting device 11 using the most common example using a glow lamp and a current limiter 10 and a yoke coil type ballast, when the E-shaped cap 9 is screwed into the light bulb socket and the power is turned on, the glow lamp 11 starts. When a power supply voltage of 100V is applied to the lamp, a glow discharge occurs, and the bimetal pole of the glow lamp 11 operates and becomes short-circuited.
A preheating current determined by the impedance of the chiyoke coil type ballast 10 and the two electrodes 5 flows through the two electrodes 5, and the electrodes 5 are sufficiently heated to emit thermoelectrons. 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 5 by the ballast, so that the lamp 1 lights up.

The lamp current was 320 mA, the lamp voltage was 53 V, the lamp power was 15 W, and the lifespan was 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. Especially the reflectance
Those using a flat lid container with a capacity of 65% or more have the characteristics of a 60W ball bulb (illuminance 54lx directly below 1m, lifespan 2000
The luminance efficiency was greatly improved and the lifespan was three times longer than that of the previous model (time), resulting in large economic benefits.

Using the Rabbit Start type ballast 12, a lamp for incandescent replacement was manufactured. When we measured the starting voltage of this lamp at low temperature (0°C), it was 145V for the lamp with the flat lid container 4 made of glass, while it was 82V for the lamps A and B with the flat lid container 4. It has been found that making the container 4 of metal has a starting assisting effect.

In that case, it is necessary to use glass container 2 and flat lid container 4 with 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.

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 and the discharge path is bent, and the fluorescent lamp is made compact, high brightness, and has a single base. Since a glass container with a partition wall and a meandering discharge path is formed by polymerizing and sealing a flat lid container made of a metal material, there is no need to apply a reflective film to the lid container, and workability is improved.
The yield during lamp production is also improved, and a fluorescent lamp suitable for mass production as a substitute for incandescent bulbs can be obtained.
