曰 13.05583⁄4 931222Βλ V. Description of the Invention (1) Technical Field of the Invention The right effect relates to a group of backlight modules, and more particularly to a backlight module capable of effectively arranging lamps and a light guide plate. · '[Prior Art] π Α In the piggyback module, the lamp as the light source must be in close contact with the light guide plate. 1) The lamp is a fragile item, and the assembly is not hanging/main. Think about the positioning between the light guide and the tube. , as shown in FIG. 1, the optical module 1 includes an iron shell 11, an L-shaped tube #12, a light guide plate 13, a rubber isolation member (rubbei_cap) 14, and an L-shaped tube. 12 and the light guide plate 13 are disposed in the iron shell, because the light source at the corner of the tube 12 is unnecessary in the backlight module, the L-shaped tube 12 is not at the corner with the light guide plate. 13 is in close proximity to 'and a rubber insulation 14' is provided thereon for positioning and isolating the light source. However, in the first figure, only the rubber insulating member i 4 is used as the branch of the fixed light guide plate 13 because the rubber insulating member 14 is a soft material, and the light guide plate 13 cannot be surely fixed, and the second is impossible. The light guide plate 13 is fixed, and the light guide plate 13 is easily pressed against the rubber knee insulating member 14 to cause the lamp tube 12 to be broken. FIG. 2 shows another backlight module 2A, which includes an iron shell 21, an L-shaped bulb 22, a light guide plate (not shown), and a rubber insulation member 24. The basic structure of the backlight module 20 is The backlight module is similar to the above, except that the optical module 20 further punches a lug 2ia on the bottom surface of the iron shell 21, since the lug 21a is located between the light guide plate and the L-shaped tube 22. It becomes a retaining wall' to ensure the positioning between the two. Between the two f / However, in the m diagram, 'because the iron shell 21 is punched - the lug 21a

'Because of the plastic material 限制 limit' and the thinner plastic material, the structural rigidity ί = = = = = = = = = = = = = = = 于 于 于 于 于 于 于 于 于 于 于The purpose of the present invention is to provide a backlight module that effectively clamps a lamp and a light guide. According to the invention, a backlight module is provided, which includes a bottom case, a plate, and a tube, wherein the frame is disposed on the bottom case, and/or a retaining wall is disposed in the frame. The bottom of the lamp is in a gap with the light guide plate group σ ' and the frame of the frame is formed in a gap with the light guide plate. It should be understood that the bottom case may be made of metal, such as iron, and the frame may be made of plastic. In the preferred embodiment, the retaining wall is located at a corner of the frame and abuts against a corner of the light guide plate, and the shape of the retaining wall is at the corner of the light guide plate.

& corresponding to another preferred embodiment, the corner portion and the light guide plate - the corner = the portion of the w W-shaped tube is closely spaced from the side of the light guide plate, and the L-shaped lamp The other side of the tube is in contact with the frame, and the light guide plate is not in close contact with the L-shaped tube. It should be understood that the backlight module and the reflection sheet are fixed, and the fixing member includes two rubber fixing members. Up, and the reflection u:, the two ends of the shaped tube are fixed to the A. The road is set on the light guide plate in such a manner as to cover the tube. In order to make the above-mentioned aspects of the present invention clear and easy to understand, the following specific description; Guangsi =, and advantages can be more specifically explained as follows. Embodiments, and with the accompanying drawings, the backlight module 1〇0 of the frame invention includes a bottom case 110, a wood light guide plate 13〇, a light tube 140, two fixing members 〇, and A reflection sheet 16(), it should be understood that there are other elements in the backlight module 100, and since it has nothing to do with the present invention, the description thereof is omitted here. The bottom case 110 is made of metal, for example, iron, which is used to carry other components, and the frame 120 is made of plastic, which is disposed on the bottom case ι1〇 and forms a block at a corner. Wall 121. The light guide plate 130 is disposed on the bottom case 11 , and is located in the frame 12 ,. The light guide plate 130 has four side edges 130a and 130b, wherein the side edges 130a are in contact with the frame 120, and the side edges 130b are connected to the lamp tube. 140 is closely attached, as shown in Fig. 4b; in addition, the shape of the wall 1 21 of the frame 1 20 corresponds to the shape of the corner 130c between the sides 1 3 0 b, and abuts against it, as shown in Fig. 5b Show.

Tea No. 93922263 V. DESCRIPTION OF THE INVENTION (4) The lamp tube 140 is assembled with the light guide plate 130 by the fixing member 150 and the reflection sheet 160, and is L-shaped as shown in Fig. 4b, and L A gap of 1 450 is formed between the bend of the shaped tube and the corner 1 30 c of the light guide plate 130, as shown in Fig. 5a, and the other part of the L-shaped tube 1400 The base member l3b is closely attached to the side of the light guide plate 130. The vertical solid member 150 is made of rubber, and the two ends 4 of the L-shaped tube 140 are fixed to the light guide plate 130, as shown in Fig. 4a. In addition, the reflective sheet 16 is disposed on the light guide plate 130 in such a manner as to cover the bulb 140. - As described above, since a retaining wall 126 is formed on the frame 12A, which is opposite to the shape of the light guide plate 13 In addition, the occurrence and disadvantages of the conventional backlight module can be avoided, the use of the rubber insulation member can be reduced, the stability of the light guide plate can be increased, and the situation of preventing the lamp tube from being broken can occur. [^, and it should be understood that in the above embodiment 'It is carried out with a l-shaped tube. But it is not limited to this. For example, the tube can also be a U-shaped or a word-shaped tube and guide. A gap is formed between the corners of the board, and the frame is divided into portions corresponding to the gap to achieve the same effect as the above embodiment. ^In the backlight module of the present invention, since it is not required to be isolated by rubber To locate the light guide plate, to make the positioning effect tube break [to save the cost of the rubber insulation and assembler: Since the bottom case does not need to be punched, the external particles can be avoided. If necessary, the design of the plastic case can be used to cover the module that carries the backlight module 16'. The module can be thinned. Although the invention has been disclosed in the preferred embodiment as above, it is not used.
