By using the first diffusion film, the blurring of the lamp tube is increased, and the interval between the lamp images is made smaller. Thus, in the third case, the number of lamps is increased, and the uniformity of the light-emitting surface is raised upward. Further, by using the second diffusion film, the uniformity of the light is raised upward by blurring the light. Without diffusing j, the two diffusion membranes are substantially overlapped, although it is somewhat difficult to reduce the tube image. Because the lens surface between the two diffusion membranes is directly incident on the light from the tube (via the diffusion plate). 1 diffuse the light of the diaphragm to reduce the tube image. . In the above, it is preferable to provide a second lens surface portion in which a plurality of protruding strips are formed to extend the protrusion of the lens surface, in order to sufficiently reduce the light bulb image. By using the second through-f face' to increase the number of lamps in the tube J in the direction perpendicular to the linear light source, the uniformity of the light-emitting surface is increased, and the number of the image of the tube is increased. And back and forth operation, you can go up and improve the lighting quality. " Invented in the light-emitting surface structure back & superimposed with a plurality of plane-fuzzy portions for causing the bits passing through the chaotic light to blur the light bulb portion to extend approximately parallel, the & holding The luminous surface is formed. In this case, a third embodiment is characterized by a light-emitting device in which a linear light source is disposed, wherein the light-emitting surface structure is composed of a member, wherein the planar portions include: a light source of the linear light source remains a degree of astigmatism of the image of the tube; and a lens portion disposed to be disposed from the mold, and having a plurality of protruding strips and a surface portion of the linear light source lens, wherein the surface portion is the thickest and is a structure The rigidity of the plate-shaped transparent material is ensured by the obscuration obtained by the obscuration portion and the increase of the lamp tube by the lens portion 1298812, No. 93101924, and the invention description (5) is transparent because the light loss by using several mm is transparent. For the loss, the illuminating, in addition, the light that is obscured by the light of the lamp tube behind the light surface to reduce the number of corrected images can improve the illuminating quality. The X-thick diffuser is used to maintain the light-emitting surface, and is expanded by the present invention because the rigidity is maintained = the efficiency is good. It is preferable that the diffusing film is not used in the blurring portion caused by light absorption.

INSTRUCTIONS (6) The mediator 3 is composed of a linear light source, specifically, a plurality of lamps are arranged in the outer casing 2 by the cold cathode lamp tube 3, and each lamp The tube 3 is mutually ordered. Moreover, in the longitudinal direction of the bulb 3 of Fig. 1, it is transmitted straight to the drawing surface. The glossy structure 4 is composed of a plurality of planar members 11 and 12, and the transparent plate 12 as the thickest member is provided with a thickness of about 3 mm, preferably about 2 mm.

Further, the surface members n, 13, and 14 which are in the form of a diaphragm are located in the opening of the outer casing 2, and have a rigidity which can prevent the bending of the light-emitting surface structure 4 for a long time. In this regard, the thickest transparent plate 12 is the same as the conventional diffusing plate, and has rigidity ensuring prevention of bending of the light-emitting surface. Transparent plate 丨 2, which can be acrylic, polycarbonate, or ^ is a cycloolefin polymer (product name: Ze〇nor, produced by ZE0N company), high transparency, at high temperatures (about 80 degrees Celsius) ) can maintain a stable shape. Further, the transparent plate 1 2 may be glass. The transparent plate 12, although holding this thickness, is substantially transparent, and there is substantially no light loss through the light inside. In this regard, conventionally, the diffusion plate holding the rigid one is milky white, and there is a lot of loss due to light absorption of a diffusing agent or the like. Since the transparent plate 12 of the present embodiment is employed, light loss can be prevented under the rigidity. The light-emitting surface 12b facing the light-transmitting plate 12' and the light-incident surface 12a on the side of the bulb 3 is formed by the first lens portion.

Inventive Note (7) The description is actually very fine. As described above, the transparent plate 12 is formed by a mirror surface. Further, in the figure, the planar member holding the lens is taken as an example of a 三角形 triangle (稜鏡). In the case of the cross-sectional shape of the protruding strip, the lens portion (lens film) may be formed separately from the cross-sectional shape of the protruding strip, and the lens portion 12b may be formed on the light-emitting surface. . The tube image is separated into multi-directional D in the direction of the transmissive surface. Because the second lens portion: two: = the same direction in the direction of the vertical square two, corresponding to each tube 3: tube 3, the tube is perpendicular to the direction of the tube, D is divided into two lines: the light two ^,,: As the size becomes smaller, the distance between the official images of the lamps will decrease as the number of the image of the lamp is increased by one. Fig. 3 is a schematic illustration of the principle of increasing the number of lamp images of Fig. 2, and the principle is as follows. 6 position (the straight position of the tube), as shown in the figure, the light directly from the tube 3 to the lens portion 12b is approximately perpendicular to the surface of the lens; 12b, such light is due to the protruding strip (稜鏡) The double reflection does not shoot. On the other hand, the positions A and C from the straight upper position B of the tube to the 〇 direction, as shown in Figs. 3A and 3C, are emitted in the front direction because of the meandering of the protruding strip (稜鏡). As a result, the tube image appears at the A and C positions. The light from one tube 3 will show two tube images. In addition, because the light of the lamp image is dispersed, the brightness of each of the lamp images is lowered, and the difference in brightness between the light and the light is reduced.

Amendment 5, invention description (8 The diaphragm 'is used to collect the light diffused by the diffuser in the = direction (the normal direction of the diffuser) to increase the glow X in the front direction, but not to image the tube. dispersion. Moreover, conventionally, the diffusion of the diffusion plate or the like is uniform before the lens of the lens. Therefore, the positions A, b, and C of =2 generate diffused light on the entire light-emitting surface. For the diaphragm, the omnidirectional light is concentrated in the front direction due to the tortuosity of the lens diaphragm (the twist of Figure A). Therefore, the lens diaphragm has a light collecting function, but has no function of dispersing the image of the tube. On the other hand, in the direct type backlight module of the present embodiment, since the linearity of the light from the lamp tube/light is maintained, the light incident on the lens portion 丨2b remains the lamp image, and the lens portion 12b is regarded as Disperse the function of the lamp image.

Configuration. For the second diffusion film, the light and the light from the tube 3 are diffused and scattered to blur the image of the tube. In other words, the 1/wide diffuser film 1 is used as a blur portion. However, due to the fact that the diffusion diaphragm is very thin, there is no such thing as a thick diffusion plate that strongly removes the image of the lamp, and a lamp image remains. κ成 As the first diffusion membrane 11, a high haze value is preferable, and a haze value of the body is preferably 80% or more.

Invention description (9) lj The light-incident surface 1 2a' is formed in a fine concavo-convex shape for obscuring the image of the tube. The fine concavo-convex shape of the transparent plate 12 can correspond to the corresponding entrance surface 2a of the molding die for forming the perforated plate 1 2 . In addition, as for the blurring portion provided in the transparent plate 丨2, it is possible to use a white dot printing to the light-incident surface 1 2 a and a bead-expanding coating. The adhesion of the diffusing member is used. Further, when the light-incident surface 12a disposed on the transparent plate 12 is used as the blur portion, the first diffusion film can be used to smear the light and dark of the image of the tube by using the blur portion. The light in the ambiguous state is incident on the first lens portion 12b because of the lenticular lens The portion 12b divides the blurred light official image into a plurality of pieces, and only uses the scattered light tube to illuminate the light-emitting surface. Otherwise, because of the difference between the fuzzy portion 11 and the ith lens portion 12b, the board 12 In the middle of the transparent layer, when the light diffused by the portion 11 reaches the ith lens portion 丨2b due to the presence of the transparent layer, the degree of blurring can be increased by delaying the surface of the i-th lens portion 丨2b.

As a result, the number of the lamp view images is larger than the number of the actual lamps 3, and some or all of the scattered image of the respective lamps coincide with other and official images to obtain uniform brightness. In this way, by repeating the dispersion of the tube image caused by the lens, the number of the tube images can be easily increased, and the illumination quality can be easily improved. Moreover, simply increasing the number of the lamp tube 2 will leave a strong difference in brightness and darkness, which may be necessary for the strong diffusion of the diffuser plate to be eliminated, because the dispersion of the tube image and the blur of the tube image are necessary. The combination is combined, and the number of the tube images is increased in a state where the difference in brightness and darkness is reduced, and a uniform light-emitting surface is easily obtained. Moreover, the planar members n, 12, 13, and 14 shown in Fig. 1 are used to protect the second lens diaphragm 14 in order to uniformize the light, and to protect the second lens diaphragm 14 (in the absence of the In the case of the lens diaphragm 14, the first transmissive portion 12b) is also included, and other optical sheets may be included for the purpose of increasing the viewing angle.
