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] Figure 1 ~ Figure 4 shows a fluorescent lamp device as a first embodiment of the present invention, figure 1 It is a perspective view showing a part of opening, figure 2 It is a front view showing a cut off part, image 3 is along figure 2 A sectional view of the A-A line, Figure 4 is along figure 2 Sectional view of the B-B line.

[0082] Figure 5 It is a sectional view which shows the lighting fixture as 1st Embodiment of this invention, and schematically shows the lighting fixture installed in the ceiling.

[0083] First, the structure of the fluorescent lamp apparatus of this embodiment is demonstrated.

[0084] Reference numeral 10 denotes a fluorescent lamp device, which is composed of an arc tube 11 , a case 12 serving as a base, and a lighting device 13 accommodated in the case 12 .

[0085] The luminous tube 11 is a curved discharge circuit that bends a straight glass tube made of transparent lead-free glass into a roughly U-shape, with both ends ...

Embodiment 2

[0155] Image 6 A fluorescent lamp device according to a second embodiment of the present invention is shown. (a) is a side view of the fluorescent lamp device, and (b) is a side view showing a state in which the fluorescent lamp device is separated from the state (a), wherein the same as the first embodiment part, attach 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. Rather, it is configured by being divided into first and second casings to form a substantially L-shape when viewed from the side.

[0157] That is, if Image 6 As shown by the dotted line dividing line b in (a), the first housing 12a forms an opening 12c, which is formed into a slightly deeper ship bottom shape and has an approximately L-shaped opening, and its structur...

Embodiment 3

[0172] Figure 7 A fluorescent lamp device according to a third embodiment of the present invention is shown, (a) is a side view of the fluorescent lamp device, (b) is a side view showing a state in which the fluorescent lamp device is separated from the state of (a), and the first and second embodiments The same symbols are attached to the same parts.

[0173] In this embodiment, instead of the fluorescent lamp device of the second embodiment, the first and second housings 12a, 12b are divided into substantially L-shaped shapes as viewed from the side. In this embodiment, the second housing 12b is placed on the The part that supports the luminous tube and the part that functions as a cover are further divided into structures.

[0174] That is, if Figure 7 As shown by the two dotted dividing lines c in (a), the first housing 12a is constituted only by the side wall portion 12a' for supporting the terminal pins 14,14.

[0175] The second casing 12b is constituted by a cover...

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 a luminescent tube including a curved discharge circuit, and a lighting fixture using the fluorescent lamp device. Background technique [0002] Previously, for example, as disclosed in Japanese Patent Laying-Open No. Hei 8-17335, which was published earlier in the following Japanese patent, the light-emitting tube was bent into a roughly U-shape, or the ends of two straight glass tubes were joined together to make a roughly H-shape. So-called compact fluorescent lamps whose structure forms a meander-shaped discharge circuit are spreading. [0003] This kind of fluorescent lamp is a fluorescent lamp with filament (filament) electrode sealed at both ends of the luminous tube, and a single lamp socket fluorescent lamp is installed. It contributes to the thinning of lighting fixtures, so it is widely used as surface light sources such as desk lamps, fluorescent lamps (baselights), and down...
