Problems solved by technology

[0012] However, Japanese Patent Laid-Open Publication No. Hei 6-283139 discloses a structure in which input pins are provided inside the housing cover, so the input pins and the lighting circuit board arranged on the housing body must be connected from the back of the housing cover. Conduct wire connection, and because the input pin is an extremely small part, wiring work is difficult

Embodiment 1

[0081] 1 to 4 show a fluorescent lamp device according to a first embodiment of the present invention, FIG. 1 is a perspective view showing a partially opened part, FIG. 2 is a front view showing a cutaway part, and FIG. 3 is a cross-sectional view taken along line A-A in FIG. 2 . , FIG. 4 is a cross-sectional view along the line B-B of FIG. 2 .

[0082] Fig. 5 is a cross-sectional view schematically showing the lighting fixture as the first embodiment of the present invention, and schematically showing the lighting fixture installed on the ceiling.

[0083] First, the configuration of the fluorescent lamp device of the present embodiment will be described.

[0084] Numeral 10 is a fluorescent lamp device, which is composed of an arc tube 11 , a housing 12 serving as a base, and a lighting device 13 housed in the housing 12 .

[0085] The arc tube 11 is a curved discharge circuit formed by bending a straight glass tube made of transparent lead-free glass into a substantially ...

Embodiment 2

[0155] 6 shows a fluorescent lamp device as a second embodiment of the present invention, (a) is a side view of the fluorescent lamp device, (b) is a side view of the fluorescent lamp device from the state (a) to a separated state, which is different from the first embodiment. The same parts are attached with the same symbols.

[0156] In this embodiment, instead of the fluorescent lamp device of the first embodiment, the first casing 12a is constituted by a box having a boat-shaped bottom surface, and the second casing 12b is constituted by a cover having a substantially U-shaped cross section. Instead, the first and second casings are divided into a substantially L-shaped shape when viewed from the side.

[0157] That is, as shown by the broken line dividing line b in FIG. 6( a ), the first casing 12 a forms an opening 12 c which is formed into a slightly deep ship bottom shape and has a substantially L-shaped opening, and is configured from a side view. Roughly L-shaped bo...

Embodiment 3

[0172] 7 shows a fluorescent lamp device as a third embodiment of the present invention, (a) is a side view of the fluorescent lamp device, (b) is a side view of the fluorescent lamp device in a separated state from the state (a), and the first and second The same reference numerals are attached to the same parts of the embodiment.

[0173] This embodiment replaces the fluorescent lamp device of the second embodiment in that the first and second casings 12a and 12b are divided into a substantially L-shaped shape in side view. In this embodiment, the second casing 12b is The part that supports the arc tube and the part that functions as a cover are further divided and constituted.

[0174] That is, the 1st case 12a is comprised only by the side wall part 12a' for supporting the terminal pins 14 and 14, as shown by two broken line dividing lines c in FIG.7(a).

[0175] The second case 12b is constituted by a lid portion 12b' which is a cylindrical case and a side wall portion 1...

Abstract

The invention is concerned with the fluorescent lamp equipment within lighting equipment that can improve the task when assembly and reduce the instrument cost. It consists of: the luminescent tube (-) that is sealed the electrode (-) on both side of the bending discharge circuit; the wiring plaque (-) that is set with the lighting accessory of the luminescent (-); the first tract (-) that supports the wiring plaque (-), that sets with the opening part (-) in order to emerge at least one part of the wiring plaque (-); the second tract (-) that covers the opening part (-) of the first tract (-); the supporting part of the luminescent tube (-) that is set one of the first tract or the second tract; the electron terminal part (-) that is set one of the first tract or the second tract.

Description

technical field [0001] The present invention relates to a fluorescent lamp device having an arc tube including a curved discharge circuit, and a lighting fixture using the fluorescent lamp device. Background technique [0002] In the past, as disclosed in Japanese Patent Laid-Open No. Hei 8-17335, the following Japanese Patent Laid-Open, the arc tube is bent into a substantially U shape, or the ends of two straight glass tubes are joined to each other in a substantially H shape, etc. A so-called compact fluorescent lamp having a structure forming a meander-shaped discharge circuit is becoming widespread. [0003] This kind of fluorescent lamp is a single-cap fluorescent lamp with filament electrodes sealed at both ends of the luminous tube, and a lamp cap is installed. It is formed in a plane shape, so that the light spreads in the plane, so that the illumination distribution can be uniform, and more It is advantageous for thinning as a lighting fixture, so it is widely use...
