Embodiment 1

[0035] Next, embodiments of the lamp device of the present invention will be described with reference to the drawings. In each figure, the same reference numerals are attached to the same constituent elements, and overlapping descriptions are omitted. FIG. 1 is a front view showing an example of a lamp device of the present invention, and FIG. 2 is a plan view seen from the direction of arrow X in FIG. 1 . The lamp in the lamp device is composed of: using the connecting pipe 11, the glass lamp tubes 1a-1f formed by six straight tubes standing side by side and adjacent to each other here are combined, and the lamp tubes 1a-1f are formed by the connecting tube 11. To the lamp function with 1 discharge circuit. In this bulb, an inert gas such as argon (Ar) or krypton (Kr), or a gas containing mercury or the like is sealed.

[0036] A pair of electrodes 16 are encapsulated by tube sealing or compression sealing at respective one ends of the lamp tube 1a and the lamp tube 1f loca...

Embodiment 2

[0051] In the lamp device of the second embodiment, the electric wire 41 and the electric wire 24 ( 42 ) are reliably electrically connected by welding together with the lap connection.

[0052] The outer electric wire of lamp device is that electric wire 24 (42) and the rod-shaped end wall in the temperature fuse 4 and is that the connection of electric wire 41 is to be connected by lap joint that electric wire 24 (42) is wound on electric wire 41, but in electric wire 24 ( 42) and 41, where the temperature of the connection part is 100°C or higher, when lap joints are used, the following provisions are made in accordance with the regulations of the Electrical Appliance and Material Safety Act.

[0053] Specifically, there is "For the connection of the part at... When the above is closely attached, when the corners of the terminal are in contact with more than 20 parts, and the entire wrapped wire is pulled toward the axial direction of the terminal with a force of 30N, the w...

Embodiment 3

[0059] In the first embodiment, the thermal fuse 4 is held by the claw piece 36 as shown in FIG. 4 , but it is common to use silicone resin or an adhesive material to fix the thermal fuse 4 in general lamps.

[0060] However, in the case of using a silicone resin or an adhesive material, since the thermal fuse 4 may be operated by heating and forced drying after coating the silicone resin or adhesive material, it cannot be used. Therefore, only a natural drying type can be used as a silicone resin or an adhesive material, but it takes a long time to dry, and it cannot be packed immediately after coating. If the lamp is moved in an incompletely dry state, the lamp may be dirty, and there is a worrying problem that the dry state has to be paid attention to. In addition, equipment and time for applying silicone resin or adhesive material are required, and the silicone resin or adhesive material required to fix the thermal fuse 4 is a problem that increases the lamp manufacturing ...

Abstract

A lamp apparatus includes: a luminous tube (1a-1f) enclosed with a electrode interiorly; a electrical wire (21-24) connecting with electrode in the luminous tube (1a-1f) derivative from the exterior of the luminous tube (1a-1f); a temperature fuse (4) jointed on the own electrical wire (41) with the electrical wire (24) derivative from the exterior of the luminous tube. The electrical wire (41) of the temperature fuse (4) is staved and the staved part is jointed with the electrical wire (24) derivative from the exterior of the luminous tube (1f). Adopting the invention needs no special parts to joint the temperature fuse and the electrical wire derivative from the exterior of the luminous tube.

Description

technical field [0001] The present invention relates to a lamp device such as a compact fluorescent lamp in which a thermal fuse is provided in a base, and a lighting fixture using the lamp. Background technique [0002] Conventionally, it is known that at the end of the life of the fluorescent lamp, the vicinity of the sealing part of the tube and the vicinity of the filament electrode of the fluorescent lamp are abnormally heated due to scattering of electron-emitting substances coated on the filament electrode or scattering of constituent materials of the filament electrode, etc. , will cause damage to the vicinity of the lamp cap made of heat-resistant synthetic resin, etc., as a countermeasure for this, a thermal fuse is installed. [0003] In this case, it is necessary to connect the external electric wire which is connected to the electrodes enclosed in the tube of the fluorescent lamp and drawn out of the tube to the thermal fuse. As a connection method, (1) connect...
