防止することができる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact fluorescent lamp. 2. Description of the Related Art In a conventional bulb-type fluorescent lamp, as shown in FIG.
And both ends 1a of the fluorescent tube 1 and the holding portion 8 of the holder 2 are fixedly held by the silicone adhesive 7. [0003] However, in the conventional bulb-type fluorescent lamp, the fixing of the fluorescent tube 1 and the holder 2 by the silicone adhesive 7 is not reliable, so that a large amount of the silicone adhesive 7 is used. Not only does this increase the cost, it also increases the curing time and significantly impairs assembly workability. Further, the silicone adhesive 7 emits low molecular siloxane from the silicone adhesive 7 due to heat during lamp operation, and thus the globe 6 becomes cloudy, which may cause an extreme decrease in luminous flux, an appearance, and a reduction in commercial value. For this reason, it is desired that the fluorescent tube 1 be mechanically fixed so that the silicone adhesive 7 is not used or the amount used is reduced. Further, since both end portions 1a of the fluorescent tube 1 are sealed by the burners, the variation in the outer diameter is large. Therefore, when fixing, it is necessary to have a structure that absorbs the dimensional variation. Therefore, a triangular rib 9a is provided on the inner surface of the holding portion 9 of the holder 2 as shown in FIG. 5 along the axial direction of the holding portion 9, and both end portions 1a of the fluorescent tube 1 are inserted into the holding portion 9 to mount the fluorescent tube 1. Although it is fixed to the holder 2, such a structure has a problem that both ends 1 a of the fluorescent tube 1 cannot be completely inserted into the holding portion 9, or even if they can be inserted, they come off. there were. SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and is an economical light bulb which is excellent in assembling workability and which can prevent a drastic decrease in luminous flux, appearance and commercial value. To provide a shaped fluorescent lamp. According to the present invention, there is provided a bulb-type fluorescent lamp comprising: a fluorescent tube; and a holder holding both ends of the fluorescent tube in holding portions. On the inner surface of the holding portion in a direction perpendicular to the axial direction of the holding portion.
Extending a plurality of convex portions, the fluorescent tube of the holder
When inserted into the holding portion, the convex portion is elastically deformed and the fluorescent
A bulb-type fluorescent lamp, which is in contact with the outer surface of a tube . [0006] With this configuration, both ends of the fluorescent tube are inserted while tilting the convex portion formed on the inner surface of the holder of the holder, and both ends of the fluorescent tube are fixed to the holder of the holder by the pushing force of the convex portion. Will be done. An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a bulb-type fluorescent lamp according to an embodiment of the present invention includes a double U-type fluorescent tube 1 and this fluorescent tube 1.
, A lighting circuit 3 for lighting the fluorescent tube 1, a case 4 containing the lighting circuit 3, a case 4 containing the fluorescent tube 1, and the case 4. And a glove 6 forming the envelope 5. As shown in FIG. 2, a plurality of convex portions 2 b having inclined surfaces are formed on the inner surface of the holding portion 2 a of the holder 2. Both ends 1a of the fluorescent tube 1 are inserted into the holding portion 2a, and the fluorescent tube 1
Is fixedly held by the holder 2. As shown in FIG. 3, after the fluorescent tube 1 and the holder 2 are fixed and held, both ends 1a of the fluorescent tube 1 and the holder 2 are fixed to each other by using a silicone adhesive 7, so that the fluorescent light is fixed. The tube 1 and the holder 2 can be more firmly fixed and held. As described above, in the bulb-type fluorescent lamp according to the embodiment of the present invention, both ends 1a of the fluorescent tube 1 are inserted while pushing down the plurality of convex portions 2b formed on the inner surface of the holding portion 2a of the holder 2. Therefore, the insertion can be easily performed, and the variation in the outer diameter of both ends 1a of the fluorescent tube 1 can be absorbed by the protrusion 2b. In addition, both ends 1a of the inserted fluorescent tube 1 are fixed by being pushed back by a force to return to the original position of the convex portion 2b, so that the both ends 1a of the fluorescent tube 1 can be prevented from coming off. Therefore, the silicone adhesive 7 for fixing and holding the fluorescent tube 1 to the holder 2 is not used, or the amount thereof is reduced, and the fluorescent tube 1 can be fixed and held to the holder 2 more firmly. It is excellent and can prevent an extreme decrease in the luminous flux, an appearance, and a decrease in commercial value. As described above, the bulb-type fluorescent lamp of the present invention can easily insert the fluorescent tube into the holder of the fluorescent tube, and the variation of the outer diameter at both ends of the fluorescent tube. The fluorescent tube inserted into the holder of the holder can be mechanically fixed without slipping out, making it economical and excellent in assembly workability, and preventing the luminous flux from drastically lowering, the appearance, and the product value from lowering. can do.
