することができる。As described above, in the bulb-type fluorescent lamp of the embodiment of the present invention, the silicone adhesive 6 for fixing both ends 1a of the fluorescent tube 1 to the holder 2 is provided by the lighting circuit 3 by the partition wall 2b provided on the holder 2. , The heat of the fluorescent tube 1 during lighting can be prevented from reaching the lighting circuit 3 through the silicone adhesive 6 , and the partition wall 2b is
Is provided on each side of both ends 1a of
In both cases, the silicone adhesive 6 is applied between the partition wall 2b and the holder.
It is located between the fluorescent tube holding part and
Prevents silicone adhesive 6 from flowing into lamp circuit 3
As well as the heat of the fluorescent tube 1
When the heat reaches the partition wall 2b, the heat is divided and provided.
Since the heat is dissipated by the partitioned wall 2b,
While the lamp is on, the heat of the fluorescent tube causes the silicone adhesive and partition walls to
Thus, it is possible to prevent the lighting circuit from reaching the lighting circuit, and as a result, malfunction of the lighting circuit 3 due to heat of the fluorescent tube 1 can be prevented. Further, conventionally, it was necessary to use an excessive amount of silicone adhesive to securely fix both ends of the fluorescent lamp to the holder, but the fluorescent lamp can be securely fixed to the holder with a small amount of silicone adhesive. . In addition, since the amount of the silicone adhesive 6 used can be easily adjusted by the partition wall 2b, the silicone adhesive 6 does not come into contact with the thin tube of the fluorescent tube 1, and the silicone adhesive 6 is not heated by the lighting. In addition to preventing the occurrence of cracks in the thin tube due to expansion and contraction of the silicone resin, the silicone adhesive 6 flows into the lighting circuit 3 and the silicone adhesive 6 covers the circuit components of the lighting circuit 3. 6 can prevent the occurrence of solder cracks due to thermal expansion and contraction.
