The lamp devices 17aM, 17a_2, and 17b-2 are arranged at extended positions in the length direction of the light source unit which is lighted by the lighting device. Thereby, the high-voltage side electric wire 46 can be shortened, and although the high-frequency current is passed through the electric wire 46, the leakage current is reduced, and the power consumption can be reduced. The high-voltage-side plug socket 25a of the lighting device is provided to the cold cathode.

As shown in Figure 11A, packing the bottom 8 Although the reflecting plate 16 is flat when it does not pass through the wire 49, as shown in FIG. 1β, the portion 16-1 passing through the wire 49 is because the reflecting plate 16 is a flexible thin layer, and is expanded It is deformed on the cold cathode tube 30 side. Here, the distance between the reflector 16 and the cold cathode tube 30 when the reflector 16 is not deformed is L1, and the reflector 16 and the cold cathode tube 16 when the reflector 16 is deformed. 3 〇 distance

11339pif.ptd Page 18 1245241 ------- --___ V. Description of the invention (15) ----- When the distance is L2, the deformation of the reflecting plate 16 by L2 is smaller than L1. In this embodiment, although; ,,; the reflecting plate 16 is deformed by the wires 49, so that the apex position of the bulged portions 16-, 1 of the thin-layer body 6 is behind the cold cathode tube 30 (boxed) Bottom surface side), the distance L2 between the reflective plate 16 and the cold cathode tube 30 is determined, and the cold cathode 30 is separated from the reflective plate 6 by a relatively large distance [丨. When the reflecting plate is shaped without ensuring the interval L2, the reflecting plate 16 is in contact with the cold cathode tube 30, etc., so that the light emitting quality is lowered. By ensuring the interval L2, the low emitting quality can be prevented even when the reflecting plate 16 is deformed. drop. In addition, in order to ensure a relatively large distance L1, the heat insulator (retainer) 37 provided at both ends in the longitudinal direction of the cold cathode tube 30 can be made larger, or the thickness of the connecting pieces 40 and 41 can be made larger. FIG. 12 is a rear view of the light emitting surface constituting body 6, and side reflectors 5, 5, 5 1 b, 5 1 c, 5 are provided on the back side (inside) of the frame 12 of the light emitting surface constituting body 6. 1 d. The side reflection plates 51 a, 5 1 b, 5 1 c, 5 1 d are when the light-emitting surface structure 6 is installed in the box 5, and the side of the linear light source 30 is located in the box 5. Those irradiated from the light source 30 directly to the side of the diffuser plate 11 are reflected on the side of the diffuser plate 11. The side reflection plates 5a, 51b, 51c, and 5 Id are made of metal, and the surface on the side of the linear light source 30 is painted white. The side reflectors 5 1 a, 5 1 b, 5 1 c, 5 1 d are mounted on all four sides of the rectangular frame-like frame 12 and have positions on both sides of the length of the linear light source 30. A pair of (long-side) side reflectors 51 a, 5 1 b and a pair of (short-side) side reflectors 51 c, 51 d each connecting both ends of each side reflector 5 1 a, 5 1 b, by The side reflectors 51a, 51b, 51c, and 51d are all moments.

11339pif.ptd Page 19 1245241 V. Description of the invention (16) --- Shaped frame (refer to Figures 13 and 14). As shown in Fig. 15, the side reflectors 51a, 51b, 51c, and 51d are fixed to the rear side of the frame 12 by screws 53. The diffuser plate 11 is also fixed to the frame 12 by the screws 53. When the light-emitting surface structure 6 having the side reflectors is installed in the box 5, the 'side reflectors 5 1 a, 5 1 b, 5 1 c, 5 1 d extend from the framework 12 to the reflector 16 In the vicinity, a light-emitting chamber 55 surrounded by a diffusion plate 丨, a reflection plate 16 and side reflectors 51a, 51b, 51c, and 5 Id is formed inside the box 5. Most of the light source unit 3 (effective light emitting area E1) is located in the light emitting room 55 except for both ends in the longitudinal direction (near the connecting pieces 40 and 41). In addition, the leading end 56 of the side reflectors 51a, 51b, 51c, 51d in the extending direction is not in contact with the reflection plate 16 of the bottom 8 of the box, and it can prevent the side reflector from damaging the reflection plate 16, so that Prevents the degradation of the light emission quality caused by the damage of the reflecting plate 16. In the space 57 behind the side reflectors 51a, 51b, 51c, 51d (the side surfaces of the box 9a, 9b, 9c, 9d, and the bottom surface 8 of the box (the reflection plates are not arranged in the areas 19a, 19b, 19c, 19d) The space surrounded by the frame 12 and the side reflectors 5 1 a, 5 1 b, 5 1 c, and 5 1 d) is the lighting device 17a-1, 17a_2, 17b-1, 17b-2, and the light source unit 3 The connector 31, the non-effective light-emitting area E 2 of the linear light source 30, the wiring 46, etc. are isolated from the light-emitting room 55. In particular, when the non-effective light-emitting area E2 of the linear light source 30 is not located in the light-emitting room 55, uneven light emission does not occur in the light-emitting room 55, and the light-emitting quality can be improved. In addition, the lighting devices 17a-1, 17a-2, 17b-1,

11339pif.ptd Page 20 1245241 V. Description of the invention (17) 1 The electrodes 34a, 34b at both ends of the 7b-2 or linear light source 30 in the length direction are located in the back space separated by the side reflector and the light emitting room 5 5 The relationship between 5 and 7 can suppress the temperature rise of the light-emitting chamber 5 5. Furthermore, the air holes 60 formed in the box-side surface portions 9a, 9b, 9c, and 9d can also ensure the cooling of the main body of the back space 57. In addition, although the outside air enters the box through the air hole 60, the side reflector makes it difficult for the outside air to enter the light-emitting chamber 55. This can prevent a sudden change in temperature and prevent the brightness of the linear light source 30 from shaking. The linear light source 30 position spans the relationship between the light-emitting room 55 and the back space 5 7. The side reflectors 5 1 a and 5 1 b on both sides of the linear light source 30 in the length direction are formed to correspond to the linear light source. The number of notches 5 to 30 through which the linear light source 30 can penetrate. Also, although the linear light source 30 spans the light-emitting room 55 and the back space 57 separated by the side reflectors, when the light-emitting surface structure 6 is taken out, the side reflectors are eliminated and can be exposed in the box 5 The entire light source unit 3 can be removed and removed. Lighting devices, plug holders, and wiring are also exposed, allowing connection of plug holders. Thus, in this embodiment, as long as the face structure 6 is taken out, maintenance and inspection of the inside of the installation can be performed. The present invention is not limited to the above-mentioned embodiments. Although the present invention has been disclosed as above with a preferred embodiment,

The present invention, '/ renhe who is familiar with this art, will not deviate from this VV: 蒦 r: =: 1 when some changes can be made and run #, so the present invention: Defined shall prevail.
