The globe 8 is fixed between the case 5 and the lamp holder 2 by means of silicone adhesive 7, and a hole 9 is arranged around the lamp holder 2, and the silicon adhesive 7 is brought into contact with the lighting device 3 through this hole 9.

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 conventionally known fluorescent lamp having at least one straight tube portion, a lighting device for the fluorescent lamp, a lamp holder for holding the fluorescent lamp, and a case including the lighting device and the lamp holder. Since the bulb-shaped fluorescent lamp including the bulb cap is used as an alternative light source for the bulb, the shape is reduced in size and weight, and the thermal load of the fluorescent lamp and the lighting device is increased accordingly, so that
The heat load was reduced by attaching a heat sink and a heat sink to the fluorescent lamp and lighting device.

[0003]

SUMMARY OF THE INVENTION In the conventional assembly in which the heat radiating plate and the heat radiating substance are attached as described above, the problem of complicated parts management due to an increase in the number of parts and the complicated and difficult assembly are involved. There was a problem.

SUMMARY OF THE INVENTION The present invention solves such a problem by providing a compact fluorescent bulb that is easy to assemble and inexpensive by reducing the number of parts and simplifying parts management. The purpose is.

[0005]

To solve this problem, the present invention provides a fluorescent lamp having at least one straight tube portion, a lighting device for the fluorescent lamp, and a lamp holder for holding the fluorescent lamp. A light bulb-shaped fluorescent lamp having a case that encloses the lighting device and the lamp holder, a globe that is attached to the case and encloses the fluorescent lamp, and a light bulb base projecting from one end of the case. Then, the globe is fixed between the case and the lamp holder with an adhesive, and a hole is provided around the lamp holder, and the adhesive is brought into contact with the lighting device through the hole. .

[0006]

With this configuration, the adhesive in contact with the lighting device transfers the heat of the lighting device to the globe or the case and radiates the heat to the outside. Excellent heat dissipation effect can be obtained without using it, and the number of parts when assembling can be reduced,
Further, it is possible to provide an inexpensive fluorescent bulb that is easy to assemble with a reduced number of assembling steps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a compact fluorescent lamp includes a fluorescent lamp 1, a lamp holder 2, and a lamp holder 2
Lighting device 3 attached to the lamp, a starting device 4 for starting the fluorescent lamp 1, a case 5 incorporating the lamp holder 2 and the lighting device 3, and a bulb cap protruding from one end of the case 5. 6 and a globe 8 which contains the fluorescent lamp 1 and is attached to the case 5 by a silicone adhesive 7. The fluorescent lamp 1 is a double U-shaped fluorescent lamp formed by further bending a U-shaped glass tube.

The lamp holder 2 is provided with a hole 9 on the periphery thereof, that is, on a surface for sandwiching the globe 8 with the case 5, and the globe 8 is attached so as not to close the hole 9. The hole 9 is provided so as to face the lighting device 3. The holes 9 may be appropriately selected from round holes, square holes, slits, etc., and are provided at appropriate intervals around the lamp holder 2.

With this structure, after the silicone adhesive 7 for fixing the globe 8 is filled in the space between the lamp holder 2 and the case 5, the globe 8 is attached and the silicone adhesive 7 is inserted through the hole 9. Flows into the lamp holder 2 and contacts the lighting device 3. Then, the heat from the lighting device 3 is transferred to the case 5 and the globe 8 through the silicone adhesive 7 and radiated to the outside of the bulb-type fluorescent lamp.

Table 1 shows the results of measuring the temperature of the lighting device 3 of a 17 W light bulb type fluorescent lamp manufactured based on the above construction. Further, as a comparative example, the results of measuring the temperature of the conventional lighting device 3 when the lighting device 3 is not in contact with the silicone adhesive 7 and does not have the configuration of the present invention are also shown.

[0011]

[Table 1]

As is clear from Table 1, the bulb-type fluorescent lamp of the embodiment of the present invention has a lower temperature of the lighting device 3 and a simpler structure than the conventional product. In the present embodiment, the heat dissipation of the lighting device 3 is taken as an example. However, when the starting device 4 needs heat dissipation such as an electronic starter, the silicone adhesive 7 is applied to the hole of the lamp holder 2 as shown in the drawing. The starting device 4 is brought into contact with the starting device 4 from 9
It is possible to radiate the heat from the outside to the outside, and it is also possible to radiate the heat from the other side at the same time.

The adhesive 7 for attaching the glove 8 is not limited to the silicone adhesive, and any adhesive that can be used may be used, but one having a higher thermal conductivity is preferable.

[0014]

As described above, according to the present invention, unlike the prior art, an excellent heat dissipation effect can be obtained without using a heat dissipation plate or a heat dissipation substance, and a reduction in the number of parts during assembly can be realized. In addition, it is possible to provide a low cost bulb-type fluorescent lamp which can simplify the parts management, can be easily assembled with a small number of assembling steps.
