Abstract

PURPOSE:To prevent crack and exfoliation at the sealing part to be generated at the time of fixing an external bulb to the shell by sealing an external bulb and an end plate closing the aperture of said external bulb with a first bonding agent and also by providing a second bonding agent for fixing the external bulb to the shell between said external bulb and shell except said sealing part. CONSTITUTION:Since a second bonding agent 11 is isolated from the sealing part A, any compressive stress is not applied to the sealing part A even when it is heated during the fixing work. However, if a second bonding agent 11 is applied up to the area corresponding to the height H of the first bonding agent 5, defective crack or exfoliation at the sealing part A increases rapidly. Since a dent 16 is formed at the neck part 2, it can effectively be prevented that the second bonding agent 11 is stuck to the sealing part A at the time of loading the shell 10, by previously coating the inside of the dent 16 with the second bonding agent 11. Moreover, this dent 16 adsorbes the cubic expansion of the second bonding agent 11 at the time of fixing work and thereby the amount of second bonding agent 11 leaking to the sealing part A can be reduced. These are effective for suppressing the defect at the sealing part A.

However, in a fluorescent lamp with such a configuration, when the shell OI is fixed to the outer tube (1), cracks or peeling occur at the sealing part (A) between the outer tube (1) and the end plate (4). , there was a problem of lowering manufacturing yield. The inventors have conducted various studies regarding the causes of this failure.

As a result, cracks and peeling of the sealing part (A) are prevented from occurring in the sealing part (A) that includes at least the end of the neck part (2) and the first adhesive (5).
A second adhesive (Ll) is interposed on the outer side of A), and compressive stress on the sealing part (A) that occurs when the second adhesive material expands in volume is the cause. We found out that.

That is, conventionally, it is most common to apply the second adhesive αυ to the shell (11;
Regarding the coating position of υ, since no particular consideration was taken in relation to the sealed part (A+), the shell a1 is located on the outer tube (1).
In the state where the seal was mounted, the second adhesive (11) was present on the outer side of the sealing part (A) as shown in FIG.

On the other hand, the sealed part (A) is formed by heat-sealing the outer tube (1) and the end plate (4) using a first adhesive (5) such as Glass 7 Watt. Therefore, distortion due to heating processing remains in the sealed portion (A), and the strength of this portion is lower than that of other portions.

The structure of the above embodiment is the second adhesive 01)
Since it is spaced apart from the sealing part fA), no compressive stress is applied to the sealing part (A) even if it is heated during the fixing operation. However, the second adhesive aυ is the first adhesive (5
), cracks and peeling defects in the sealed portion (A) will rapidly increase if the adhesive is applied to a location corresponding to HJ. Also,
Since a hole (I [9) is formed in the neck part +21, if you apply the second adhesive αυ inside the hole (I [9) in advance, it will be possible to insert the outer tube into the shell. Compared to the conventional one in which the second adhesive 0υ is applied to (10a), it is possible to effectively prevent the second adhesive 0υ from adhering to the sealing part Qll when attaching the shell +11, and furthermore, Tonokuhomi 0 [9
absorbs the volume expansion of the second adhesive 0υ during the fixing operation, so it is possible to reduce the flow of the second adhesive (1υ) toward the sealing part (A). It works well to suppress defects in the attached part (A).

Incidentally, the Kuhomi gradient is not necessarily required, but the inventors of the present invention have used Kuhomi (2) as a suitable second adhesive (11) when IF5 is not formed. We propose a foamable adhesive tape.This adhesive tape has an epoxy resin as its main component, and if it is formed to a width of 5 mm and a thickness of 0.5 mm, it can be used with a second adhesive as shown in Figure 5. α

As explained above, the present invention seals an outer tube and an end plate that closes the opening of the outer tube with a first adhesive, and
A second adhesive is placed between the outer tube and the shell that avoids this sealing part, which prevents the sealing that occurs during the bonding process between the outer tube and the shell. This prevents cracking and peeling of the parts, thereby improving manufacturing yields and has enormous industrial value.
