Then, the right-hand adjacent light source cell 3-2 of light source cell 3-1, it is longitudinally towards opposite with light source cell 3-1, and the 1st brace 40 is configured in the 2nd non-reflecting plate configuring area 19b side, and the 2nd brace 41 (with current-carrying plate 48) is configured in the 1st non-reflecting plate configuring area 19a side.Therefore, the cold-cathode tube electrode 43a that connects high-pressure side connector 47 is in the 2nd non-reflecting plate configuring area 19b side, and the cold-cathode tube electrode 43b that connects low-pressure side connector 50 is in the 1st non-reflecting plate configuring area 19a side.
And then, the right-hand adjacent light source cell 3-3 of light source cell 3-2, it is longitudinally towards opposite with light source cell 3-2, and identical with light source cell 3-1.Again, the light source cell 3-4 of light source cell 3-3 right-hand adjacent (rightmost side among Fig. 9), it is longitudinally towards opposite with light source cell 3-3, and identical with light source cell 3-2.
Described lamp device 17a-1,17a-2,17b-1,17b-2 light each light source cell respectively, connect into as shown in figure 10, promptly the 1st lamp device 17a-1 lights light source cell 3-1, the 2nd lamp device 17b-1 lights light source cell 3-2, the 1st lamp device 17a-2 lights light source cell 3-3, and the 2nd lamp device 17b-2 lights light source cell 3-4.
Described lamp device 17a-1,17a-2,17b-1,17b-2 and light source cell 3 the corresponding configuration of direction is set, be located at non-reflecting plate configuring area 19a, the 19b of the high voltage side electrode 43a side of cold-cathode tube 30.That is, the 1st lamp device 17a-1,17a-2 are in the 1st non-reflecting plate configuring area 19a, and the 2nd lamp device 17b-1,17b-2 are in the 2nd non-reflecting plate configuring area 19b.In other words, it is distolateral that the 1st lamp device 17a-1,17a-2 are in cold-cathode tube 30 vertical, and the 2nd lamp device 17b-1,17b-2 are in cold-cathode tube 30 vertical another is distolateral.
Though lamp device heating as mentioned above, by with a plurality of non-reflecting plate configuring area 19a, the 19b of a plurality of lamp device decentralized configuration in cold-cathode tube 30 vertical both sides, thereby disperses heat generation source, can prevent the interior temperature rising of locking apparatus.In addition, cold-cathode tube Yin Wendu raises and brightness will reduce, prevents that temperature from raising and also can reach the purpose that prevents the brightness reduction so utilize.Owing to be the decentralized configuration lamp device, even thereby the lamp device longitudinal length greater than the width of light source cell 3, also lamp device can be set.
Each lamp device 17a-1,17a-2,17b-1,17b-2 are configured in the longitudinal extension position of the light source cell that this lamp device lights, and make each lamp device 17a-1,17a-2,17b-1,17b-2 and respectively light the high voltage side electrode 43a of the bright cold-cathode tube of mounted point 30 approaching.Thus, can shorten the length of high-pressure side electric wire 46, even electric wire 46 flows through high-frequency current, leakage current is also few, can reduce power consumption.The high-pressure side out connector 25a of lamp device is arranged on the side of a face 21a of the circuit board 21 of setting, make it towards cold-cathode tube 30 (electrode 43) side, thereby can shorten the distance between lamp device connector 25a and the cold-cathode tube high voltage side electrode 43a.
Because lamp device is configured in cold-cathode tube high voltage side electrode 43a one side, makes lamp device away from cold-cathode tube low-voltage side electrode 43b, even but electric wire 49 prolongations of low-pressure side, also the leakage current than high-pressure side electric wire 46 lacks, and can suppress the leakage current of whole device.Even the electric wire of low-pressure side 49 prolongs, also only have one in the light source cell 3, thereby wiring is simple.
In order to shorten the length of low-pressure side electric wire 49 as far as possible, make electric wire 49 by between reflecting plate 16 and the housing bottom 8.According to the configuration of light source cell shown in the figure 3 and lamp device, then at electric wire 49 by between reflecting plate 16 and the housing bottom 8 time, electric wire 49 need be circuitous at non-reflecting plate configuring area 19a, 19b, 19c, 19d, perhaps the top by reflecting plate.Yet the former prolongs electric wire 49, and especially to light source cell 3-2,3-3, electric wire 49 is very long.The latter makes the electric wire 49 on the reflecting plate 16 form shade, will reduce luminous mass.In contrast, if this electric wire passes through, then can avoid this problem between reflecting plate 16 and housing bottom 8.
Shown in Figure 11 (a), the reflecting plate 16 on the housing bottom 8 then is the plane if do not pass electric wire 49; Shown in Figure 11 (b), the part 16-1 that electric wire 49 passes because reflecting plate 16 is flexible sheet bodies, thereby produces deformation, becomes the state that bloats to the cold-cathode tube side.
Here, suppose that the distance of this plate and cold-cathode tube 30 was L1 when reflecting plate 16 was undeformed, the distance of this plate and cold-cathode tube 30 is L2 during reflecting plate 16 deformation, then because of reflecting plate 16 deformation, makes L2 less than L1.In this example, even reflecting plate 16 produces deformation because of electric wire 49, the bellying 16-1 front end of plates 16 also is positioned at the behind (housing bottom surface sections side) of cold-cathode tube 30, make cold-cathode tube 30 leave reflecting plate 16, form bigger distance L 1, to guarantee the interval L2 between reflecting plate 16 and the cold-cathode tube 30.When reflecting plate deformation,, then form reflecting plate 16 and contact with cold-cathode tube 30 etc., luminous mass is reduced, but guarantee L2 at interval, even then reflecting plate 16 generation deformation also can prevent the luminous mass reduction if do not guarantee at interval L2.
In order to ensure bigger distance L 1, can strengthen the thermal insulation material (maintenance body) 37 that cold-cathode tube 30 vertical two ends are provided with, perhaps thicken brace 40,41.
Figure 12 shows that the rear view of light-emitting area composition body 6.The rear side (inboard) that light-emitting area is formed the framework 12 of body 6 is provided with side reflector 51a, 51b, 51c, 51d. Sidepiece reflecting plate 51a, 51b, 51c, 51d install light-emitting area when forming body 6 in housing 5, be positioned at the side of linear light source 30 in housing 5, be used for directly from light source 30 be not towards diffusion version 11 but the light of irradiation side to diffuser plate 11 lateral reflections. Sidepiece reflecting plate 51a, 51b, 51c, 51d make with metal, the surface applied white of its linear light source 30 sides.
As shown in figure 15, with screw 53 side reflector 51a, 51b, 51c, 51d are fixed on the rear side of framework 12.Diffuser plate 11 also is fixed on the framework 12 with this screw 53.
If will be equipped with the light-emitting area composition body 6 of side reflector installs in the housing 5, near then side reflector 51a, 51b, 51c, 51d extend to reflecting body 16 from framework 12, at the housing 5 inner illuminated chambers 55 that surround by diffuser plate 11, reflecting plate 16 and side reflector 51a, 51b, 51c, 51d that form.Light source cell 3 is except that vertical two ends (near the brace 40,41), and most of (effectively luminous zone E1) is positioned at illuminated chamber 55.The direction front end 56 that stretches out of side reflector 51a, 51b, 51c, 51d is quick condition, does not contact the reflecting plate 16 of housing bottom 8, prevents that reflecting plate 16 from damaging because of side reflector, and then prevents that reflecting plate 16 damages from causing luminous mass to reduce.
Non-effective luminous zone B2, wiring 46 of web member 31, the linear light source 30 of lamp device 17a-1,17a-2,17b-1 and 17b-2, light source cell 3 etc. are housed the space that behind space 57 of side reflector 51a, 51b, 51c, 51d (case side facial 9a, 9b, 9c and 9d, housing bottom surface sections 8 (non-reflecting plate configuring area 19a, 19b, 19c, 19d), framework 12 and side reflector 51a, 51b, 51c, 51d surround), separate with illuminated chamber 55.Especially non-effective luminous zone E2 of linear light source 30 is not positioned at illuminated chamber 55, thereby does not produce non-uniform light in the illuminated chamber 55, and luminous mass is improved.
Electrode 34a, the 34b at lamp device 17a-1,17a-2,17b-1,17b-2 and linear light source 30 vertical two ends of heating are positioned at the space, behind 57 that separates with illuminated chamber 55 with side reflector, thereby suppress the temperature rising of illuminated chamber 55.And the pore 60 that also utilizes case side facial 9a, 9b, 9c, 9d to form guarantees that itself cool off in space 57 behind.Even extraneous air enters in the housing from pore 60 in addition, also utilize side reflector to make extraneous air be difficult to enter illuminated chamber 55, thereby can prevent that temperature from sharply changing, can prevent the brightness drift of linear light source 30.
Linear light source 30 will pass the intersection between illuminated chamber 55 and the space 51, behind, thereby side reflector 51a, the 51b of vertical both sides of linear light source 30 form the breach 58 that runs through usefulness with the corresponding formation linear light source 30 of quantity of linear light source 30.
Though linear light source 30 is crossed over illuminated chamber 55 and space 57, behind that side reflector is divided into, if the light-emitting area of dismantling is formed body 6, then removes side reflector, whole light source unit 3 exposes in housing, detachable light source unit 3.Lamp device, connector, wiring class are also exposed, and can connect connector etc.Like this, this example is only dismantled light-emitting area and is formed body 6 and just can carry out the Maintenance and Repair of device inside.
The invention is not restricted to above-mentioned example.
