JPH0714549A - Bulb type fluorescent lamp - Google Patents

Abstract

PURPOSE:To prevent the malfunction of a lighting circuit caused when the heat of the electrode section of a fluorescent tube is transferred to the lighting circuit through a silicone adhesive. CONSTITUTION:This bulb type fluorescent lamp is provided with a double U-shaped fluorescent tube 1, a holder 2 holding both end sections 1a of the fluorescent tube 1, a lighting circuit 3 for lighting the fluorescent tube 1, a case 4 storing the light circuit 3, and a globe 5 storing the fluorescent tube l held by the holder 2 and constituting an envelope 7 together with the case 4. Both end sections 1a of the double U-shaped fluorescent tube 1 are fixed and held to the holder 2 with a silicone adhesive 6, and a partition wall 2b partitioning both end sections la of the fluorescent tube 1 and the lighting circuit 3 is provided between the hold section 2a holding both end sections 1a of the fluorescent tube 1 of the holder 2 and the lighting circuit 3 on the holder 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact fluorescent lamp.

[0002]

2. Description of the Related Art A conventional compact fluorescent lamp is shown in FIGS.
As shown in FIG. 3, both end portions 1a of the fluorescent tube 1 were fixedly held to the holding portion 2a of the holder 2 using the silicone adhesive 6.

[0003]

However, in the conventional compact fluorescent lamp, when the silicone adhesive 6 is injected into the holding portion 2a of the holder 2, the silicone adhesive 6 reaches the lighting circuit 3, The heat of the electrode portion of the fluorescent tube 1 during lighting is transmitted to the lighting circuit 3 through the silicone adhesive 6, and the heat causes a malfunction of the lighting circuit 3.

The present invention has been made to solve such a problem, and provides a bulb-type fluorescent lamp in which the lighting circuit does not malfunction due to heat of the electrode portion of the fluorescent tube during lighting. Is.

[0005]

A compact fluorescent lamp according to the present invention comprises a fluorescent tube, a holder that holds both ends of the fluorescent tube in holding sections, a lighting circuit for lighting the fluorescent tube, and A case containing the lighting circuit and the fluorescent tube are stored.
And a globe that forms an envelope with the case, both ends of the fluorescent tube are fixedly held by the holder with a silicone adhesive, the holder, the holder of the holder and the lighting circuit. A partition wall is provided between the both ends of the fluorescent tube and the lighting circuit.

[0006]

With this configuration, it is possible to prevent the silicone adhesive for fixing both ends of the fluorescent tube to the holder from reaching the lighting circuit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a compact fluorescent lamp according to an embodiment of the present invention comprises a double U-shaped fluorescent tube 1 and a holder 2 in which both ends 1a of the fluorescent tube 1 are held by holding portions. A lighting circuit 3 for lighting the fluorescent tube 1, a case 4 accommodating the lighting circuit 3, and a globe 5 accommodating the fluorescent tube 1 and forming an envelope 7 with the case 4 are provided. . Double U
Both ends 1a of the shaped fluorescent tube 1 are fixedly held to a holder 2 with a silicone adhesive 6, and a partition wall 2b is provided between the holding portion 2a of the holder 2 and the lighting circuit 3.

As described above, in the light bulb type fluorescent lamp of the embodiment of the present invention, the silicone adhesive 6 for fixing the both ends 1a of the fluorescent tube 1 to the holder 2 is lit by the partition wall 2b provided in the holder 2. Therefore, the heat of the fluorescent tube 1 during lighting can be prevented from reaching the lighting circuit 3 through the silicone adhesive 6, and as a result, the malfunction of the lighting circuit 3 due to the heat of the fluorescent tube 1 can be prevented. Can be prevented.

In the above embodiment, the holder 2a of the holder 2 and the partition wall 2b are provided separately from each other. However, even if the partition wall 2b is connected to the holder 2, the same effect as above can be obtained. In addition, the holder 2 can be prevented from warping.

[0010]

As described above, in the compact fluorescent lamp of the present invention, the silicone adhesive for fixing the both ends of the fluorescent tube to the holder separates both ends of the fluorescent tube provided in the holder and the lighting circuit. Since the partition wall can prevent the lighting circuit from reaching the lighting circuit, the heat of the fluorescent tube during lighting can be prevented from reaching the lighting circuit through the silicone adhesive. As a result, the operation of the lighting circuit by the heat of the fluorescent tube It is possible to prevent defects.
