Embodiment
Below with reference to accompanying drawing illustrative embodiment is described.
Shown in Figure 1A and 1B, lighting device 1 comprises fluorescent lamp 2 as discharge lamp, electrically connects binding post 3, and this binding post 3 engages separably with the lead-out wire 7 of the cold cathode 6 of fluorescent lamp 2, and socket 4, its middle connecting terminal 3 is installed in the socket 4 separably and electrically connects.
Fluorescent lamp 2 has cylindrical glass tube 5, and has cold cathode 6 in an end of glass tube 5.Cold cathode 6 has lead-out wire 7, and separate point-blank along axis direction its end from glass tube 5.As above-mentioned fluorescent lamp 2, for instance, this fluorescent lamp be have diameter be about 3 to 4mm and length be about the fluorescent lamp of 12mm.
As Fig. 2 A, 2B, shown in the 2C, binding post 3 is made by the electric conducting material of for example metal material etc., this binding post comprises square tube shape terminal part 8 and cylindrical standing part 9, wherein square tube shape terminal part 8 is connected with the lead-out wire 7 of fluorescent lamp 2, and cylindrical standing part 9 is used for fixing its outer peripheral areas at fluorescent lamp 2 one ends.
As Fig. 3 A, 3B, 4A, shown in the 4B, 8 the inner periphery zone in the terminal part has formed one group of terminal plate 11 at the relative position place, and this terminal plate forms space 10, and by this space, the lead-out wire 7 of fluorescent lamp 2 can insert and shift out along its axis direction.Terminal plate 11 effect is, when the lead-out wire 7 of fluorescent lamp 2 inserts and shifts out space 10, its can along terminal plate mutually near or the reverse elasticity that separates move.
Shown in Fig. 2 A and 2C, in the inner circumferential surface of standing part 9, become hemispheric fixed lobe part 14 to form in a circumferential direction three positions highlightedly substantially, its exterior circumferential surface with fluorescent lamp 2 contacts.By these fixed lobe parts 14, fluorescent lamp 2 obtains to support at three some places of standing part 9.
Simultaneously, as Fig. 2 B, 2C shown in 4A and the 4B, has position adjustments sheet 12 in the standing part 9, and its end face with fluorescent lamp 2 contacts, and is used to regulate this endface position.
In addition, shown in Fig. 2 A, standing part 9 has slit 15, and it along the circumferential direction separates standing part 9.By above-mentioned slit 15, standing part 9 along the circumferential direction can flexibly move, thereby has alleviated stress for being applied to the standing part 9 that is used for fixing fluorescent lamp 2 thus, thereby fluorescent lamp 2 can be fixed reliably.
As shown in Figure 5, socket 4 comprises a set of bond sheet 17, and its exterior circumferential surface with the terminal part 8 of binding post 3 engages.In addition, socket 4 electrically is connected with lighting circuit part (not shown), thereby provides electric current for the lead-out wire 7 of fluorescent lamp 2.For lighting device 1, binding post 3 is installed in the socket 4 separably, thereby electrically connects by joint fastener 17, and this can simplify assembly work.
About the lighting device 1 of above-mentioned configuration, the lead-out wire 7 of describing fluorescent lamp 2 in conjunction with the accompanying drawings is connected to the situation of the terminal part 8 of binding post 3.
At first, in lighting device 1, fluorescent lamp 2 inserts in the standing part 9 of binding post 3 along axis direction, makes the end face of fluorescent lamp 2 and position adjustments sheet 12 offset, and partly the be fixed fixed lobe part 14 of part 9 of the exterior circumferential of fluorescent lamp 2 is fixed.
Secondly, the outer peripheral areas of fluorescent lamp 2 part 9 that is fixed is fixing, and the lead-out wire 7 of fluorescent lamp 2 is inserted in the space 10 between the terminal plate 11 of terminal part 8 of binding post 3, makes fluorescent lamp 2 electrically be connected with terminal plate 11.Terminal part 8 engages with the joint fastener 17 of socket 15, makes the binding post 3 that is connected with fluorescent lamp 2 electrically be connected with the lighting circuit part.
Comprise under the situation of 2, one binding posts 3 of a fluorescent lamp and a socket 4 at supposition lighting device 1, described above-mentioned lighting device 1.Yet, lighting device 1 also can be configured to comprise a plurality of fluorescent lamps 2, a plurality of binding posts 3, wherein each binding post is connected to the lead-out wire 7 of fluorescent lamp 2, a plurality of sockets 4, binding post 3 has been installed in this socket separably, and the circuit board (not shown), it is included as the lighting circuit part of a plurality of fluorescent lamp 2 common lands configurations.
As mentioned above, lighting device 1 comprises binding post 3 and socket 4, and this binding post 3 fixedly fluorescent lamp 2 also electrically is connected to lead-out wire 7, and binding post 3 is installed in the socket 4 separably.Under such configuration, the lead-out wire 7 of fluorescent lamp 2 can easily with reliably be connected, and has simplified the structure of lighting device 1, and has reduced manufacturing cost.
That is to say that lighting device 1 has the syndeton that is called as the glass tube fuse type, wherein lighting device 1 is connected to socket 4 by binding post 3, and need not to use the electrical harness lead that is connected to lead-out wire.Therefore, unlike the prior art, lighting device 1 need not welding, thereby has reduced the difference that the workman causes in the manufacture process, and it is stable that the quality of lighting device keeps.Therefore,, can reduce the number of the artificial and parts in the assembly work, reduce the in poor shape welding job of solder joints according to the present invention, and the fracture that reduces lead-out wire.
Syndeton according to discharge lamp of the present invention and lighting device is suitable for LCD as illumination light source, and for example, from the rear surface side of LCD panel, it is called as backlight.In addition, be suitable for illumination as billboard, show stand etc. according to the syndeton of discharge lamp of the present invention and lighting device, or backlight as the amusement apparatus of marbles disc apparatus etc. and relevant device.
Although above-mentionedly with reference to particular exemplary embodiment the present invention is illustrated and describes, the present invention is not limited to these embodiment.Those skilled in the art will recognize that the multiple change that on the basis that does not deviate from the present invention's spirit that the aforesaid right requirement limited and protection range, can carry out on form and the details.
