Fluorescent lamps can be used with lower power consumption than general incandescent bulbs, and have a high lighting efficiency, so the applicant has recently developed a fluorescent lamp that can be used by directly screwing into an existing incandescent bulb socket. The device has been put into practical use and is becoming widely used as a power-saving light source. This device constitutes an envelope by connecting a globe to a cover with a screw-type cap at one end, and the envelope has a continuous outer surface, such as a sphere or an oval sphere, as a whole. It has a single integrated shape, that is, a unified shape, and has a curved tube-shaped fluorescent lamp bent into a roughly saddle shape, for example, and a circuit element for starting and lighting the fluorescent lamp in this envelope. If it is integrated into a unit, it becomes a structure.

とともに点灯中発熱する限流素子はカバー側に収
容し、けい光ランプと限流素子とを別々の空間に
分離して配置する等の工夫がなされている。 By the way, when a fluorescent lamp and a circuit element are installed in the same space inside the envelope, the temperature inside the envelope rises due to radiant heat from current limiting elements such as ballasts and the lamp itself while the lamp is on. Due to thermal effects, the mercury vapor pressure within the lamp becomes higher than the optimum value, causing problems such as a decrease in luminous efficiency. Conventionally, as a countermeasure for this, ventilation holes were created on the circumference or top of the envelope to increase the heat dissipation effect inside the envelope, or partition plates were used to separate the inside of the envelope from the glove side and the cover side. The curved fluorescent lamp is housed in the globe, the current-limiting element that generates heat during lighting is housed on the cover side, and the fluorescent lamp and current-limiting element are placed separately in separate spaces. Efforts have been made to
しかしながら、前者のように外囲器に通気孔を

However, if a ventilation hole is provided in the envelope as in the former case, there is a risk that insects, dust, etc. may enter the envelope through the ventilation hole, and since there are holes on the periphery and top of the envelope, there is a risk of incandescent heat. The image becomes somewhat different from the image of a light bulb, and the appearance becomes undesirable. Therefore, it is desirable to eliminate such ventilation holes, or even if it is not possible to eliminate them, to reduce the size of the ventilation holes. Furthermore, even if the fluorescent lamp and the current limiting element are separated by a partition plate as in the latter case, there is heat conduction through this partition plate, so the heat shielding effect for the fluorescent lamp is still insufficient in practical use. are doing.
なお、ランプの周囲温度を低下させる他の手段
としてランプ電流を絞るという2次的な方法もあ
るが、ランプ電流を絞ると明るさの低下を伴うた
め、さらにこのための対策が必要となる等の問題
が生じる。 As another method for lowering the ambient temperature around the lamp, there is a secondary method of reducing the lamp current. However, reducing the lamp current also results in a reduction in brightness, which creates problems such as the need for further measures to address this.
また、このような問題点は、水銀蒸気圧を適正
に保つために用いられるアマルガムを用いても同

正化は不可能となつてくるという問題が存在す
る。 Further, such problems occur even when amalgam is used to maintain an appropriate mercury vapor pressure. In other words, amalgam has a lower mercury vapor pressure than pure mercury, so it is possible to maintain the mercury vapor pressure inside the tube at an appropriate value even at high temperatures, but if the temperature gets too high, the mercury vapor pressure cannot be adjusted to an appropriate value. The problem is that it becomes impossible.

The present invention aims to provide a fluorescent lamp device that can be maintained.

し10mmに設定してある。 On the other hand, the glove 3 has a substantially spherical shape and is made of a translucent synthetic resin material that is milky white or colorless and transparent. The glove 3 has an opening 1 on a part of its circumference.
0, and a support plate 11 is attached to this opening 10 to close it. And this support plate 11
Therefore, the inside of the globe 3 forms a space that is partitioned and independent from the outside, and a curved tube-shaped fluorescent lamp 12 is attached to the surface of the support plate 11 on the globe 3 side. This curved tube type fluorescent lamp 12 has a straight tube type glass bulb at the center between both ends 13, 13 of approximately U.
The central curved portion 14 is formed by bending the central curved portion 14 into a letter shape, and the central curved portion 14 and both end portions 13, 13
A pair of both-end bent portions 1 are formed by bending the ends into a substantially U-shape in a direction substantially orthogonal to a plane including the U-shape.
5 and 15, and by bending these two times, the end portions 13, 13 and the central curved portion 14 are positioned adjacent to each other in the same direction, so that the overall shape resembles a saddle for horseback riding. Because of this, it is called a saddle-shaped fluorescent lamp. Filament coils 16, 16 are sealed to both ends 13, 13 of the curved fluorescent lamp 12. Such a curved tube-shaped fluorescent lamp 12 is housed in the globe 3, with both end portions 13, 13 and a central bent portion 14 facing the support plate 11. Further, a starting circuit component 17 is housed within the glove 3. The starting circuit component 17 includes a lighting tube 18 and this lighting tube 1.
8 and a capacitor 19 connected in parallel to the filament coils 16 and 16, and is connected between one lead wire 20a and 21a connected to the filament coils 16 and 16. A pair of terminal pins 22a and 22b are protruded from the center of the support plate 11, and these terminal pins 22a and 22b are connected to the filament coil 1, respectively.
The other lead wires 20b, 21b connected to 6, 16
It is connected to the. Also, the terminal pins 22a, 22b
are detachably connected to the support fittings 7a and 7b on the cover 2 side, and through this connection, the curved fluorescent lamp 12 including the starting circuit component 17 and the ballast 6 are electrically connected. The cover 2 and the globe 3 are connected mechanically to form a chiyoke coil type circuit as shown in FIG. 3, and the spherical envelope 1 is formed. . When the cover 2 and the glove 3 are connected, the cover plate 5 and the support plate 11 are spaced apart from each other, and a heat insulating air layer 23 open to the outside of the envelope 1 is formed between them. In this embodiment, the interval L between the heat insulating air layers 23 is set to 2 mm to 10 mm.
なお、第3図中24は電源を示す。 Note that 24 in FIG. 3 indicates a power source.

て熱遮効果がより向上する利点がある。 According to this configuration, the interior of the cover 2 that accommodates the ballast 6 and the interior of the globe 3 that accommodates the curved fluorescent lamp 12 and the starting circuit component 17 are separated via the heat insulating air layer 23. Therefore, it becomes difficult for the radiant heat from the ballast 6 to be transmitted to the globe 3 side during lighting, so that an increase in the ambient temperature of the curved fluorescent lamp 12 can be reliably prevented and lighting efficiency can be maintained. In particular, the present inventor investigated the effect of the heat insulating air layer 23 on the support plate 11 when the width L of the heat insulating air layer 23 was varied, and the results shown in FIG. 4 were obtained. . From FIG. 4, it has been confirmed that the temperature of the support plate 11 drops rapidly when the distance L between the heat insulating air layers 23 exceeds 2 mm.
It is presumed that when the width L of the heat insulating air layer 23 is 2 mm or more, an air flow is generated within the heat insulating air layer 23, and the support plate 11 is cooled by this air flow. If it is set to 2 mm or more, there is an advantage that the heat shielding effect is further improved together with the inherent heat insulating effect of this heat insulating air layer 23.

る。 Further, according to the above configuration, there is no need to make ventilation holes on the circumferential surface of the globe 3 as in the past, or even if the ventilation holes are made, they can be made small, so the appearance can be brought closer to the image of an incandescent light bulb, and Intrusion of foreign substances such as insects and dust into the glove 3 can be eliminated or suppressed, and staining of the inner surface of the glove 3 and the fluorescent lamp 12 can be suppressed.
また、上記構成によれば、空気断熱層を介して

ことができる。 Further, according to the above configuration, heat is efficiently radiated through the air heat insulating layer, so that the rise in the ambient temperature of the fluorescent lamp and the temperature rise on the circuit side can be reduced.

必要はなく、経剤的である。 On the other hand, in the device configured as described above, the curved fluorescent lamp 12 and the lighting tube 18 generally have a shorter lifespan than the ballast 6, but in this embodiment, the support fittings 7a,
7b and the terminal pins 22a, 22b both have the function of electrical connection between the curved fluorescent lamp 12 and the ballast 6, and the function of mechanical connection between the cover 2 and the globe 3, and are also used as supporting metal fittings. 7a, 7b
Since the terminal pins 22a and 22b are detachable from each other, by separating the cover 2 and the globe 3, the fluorescent lamp 12 and the ballast 6 can be separated at the same time. Therefore, if an integrated globe 3, curved fluorescent lamp 12, and starting circuit component 17 are prepared as separate parts for repair, the curved fluorescent lamp 12 and the starting circuit component 17 can be easily replaced. Even if these parts reach the end of their service life, only these parts can be replaced. Therefore, the cover 2 side including the relatively expensive ballast 6 can be used repeatedly as is, and there is no need to replace the entire device with a new one when the fluorescent lamp 12 or lighting tube 18 reaches the end of its life. It is drug-like.

様の効果を奏する。 Note that the present invention is not limited to the first embodiment described above, and a second embodiment of the present invention is shown in FIG. That is, this second embodiment uses an annular fluorescent lamp 31 instead of the saddle-shaped fluorescent lamp described above.
The fluorescent lamp 31 is housed in a globe 34 formed by abutting a pair of substantially dish-shaped globe structures 32 and 33, and one globe structure 32 has a central part. A recess 36 into which the cover 35 containing the stabilizer 6 is inserted is provided, and a heat insulating air layer 23 is provided between the wall surface of the recess 36 and the outer wall surface of the cover 35. Although the overall appearance of the device is different in this second embodiment,
Since the annular fluorescent lamp 31 and the ballast 6 are separated by the heat insulating air layer 23, the same effect as in the first embodiment is achieved.
また上述した実施例では、始動回路部品をグロ

要なことは言うまでもない。 Further, in the above-described embodiment, the starting circuit components are housed within the glove, but they may also be housed on the cover side, and it goes without saying that in this case, a supporting metal fitting and four terminal pins are required.

Furthermore, when electronic lighting circuits are used, the possibility of thermal damage to circuit components is extremely reduced.

In the present invention described in detail above, the cover and the glove are constructed in separate rooms that are partitioned and independent from each other and the outside, and the lighting circuit components are housed within the cover, and the fluorescent lamp is housed on the glove side. In addition, since the cover and the globe were connected through an insulating air layer extending outside the envelope, the fluorescent lamp and the lighting circuit components were separated through the insulating air layer. Mutual thermal influence between the lighting circuit components and the fluorescent lamp (on the glove side) is reduced, so that an increase in the ambient temperature of the fluorescent lamp can be reliably prevented and lighting efficiency can be maintained at a high level. Moreover, it is not necessary to make ventilation holes in the glove as in the past, or the holes can be made small, which not only improves the appearance but also prevents foreign substances such as insects and dust from entering the glove. It has excellent effects such as being able to suppress staining of the inner surface of the glove and the fluorescent lamp.
