Description of the Invention: [Technical Field] The present invention relates to a light source module structure; in particular, the present invention relates to a lamp tube frame applied to a light source module structure. [Prior Art] Display panels and display devices using thinned display panels have gradually become mainstream in various types of display devices. For example, various panel displays, flat-panel TVs for homes, flat-panel monitors for personal computers and laptops, and display screens for mobile phones and digital cameras are all electronic products that use a large number of thin display panels. One of the most important components in the display panel is the light source module structure. The conventional light source module structure includes a light source module and a lamp holder. A partial schematic view of a conventional lamp holder 20 is shown. The lamp holder 2 includes a frame 22 and a reflection sheet 24. The frame 22 has a joint surface 22 and the reflection sheet 24 is coupled to the joint surface 221 of the frame 22 to reflect the light leaked from the light source module. In general, there are many conventional ways of combining the reflective sheet with the joint surface of the frame; in the example shown in Fig. 1, the adhesive 26 is manually applied to the reflective sheet 24 to adhere the reverse = 24 to the frame. The joint surface 221 of n 22 is on. This type of joining consumes considerable labor costs and the risk that the adhesive may fail. In another example, the frame is first ejected by secondary injection molding, and then the reflection 1 (not shown) is emitted in the same mold. The conventional technique of such secondary injection molding has a high cost of equipment. Moreover, the frame and the reflector have different stresses, and the frame and the reflection sheet are easily pulled and deformed. In addition, in the above technique, during the pasting process or in the process of injection molding, it may be caused by the fact that the reflective sheet and the frame (10) are not easy to be misaligned. SUMMARY OF THE INVENTION The purpose of this month is to provide a light source module structure and a utility model for the truss structure, which is effective for reversing the stick body. The light source module structure of the present invention comprises a light source module and a lamp tube holder. The light source module and the lamp are connected to each other. The light-receiving group contains the words, and the lamp holder contains the frame and the reflection sheet. In a preferred embodiment, the frame of the lamp holder includes a joint surface, a positioning surface, and a recess. The joint surface has a plurality of weld recesses, and the reflection sheet has a plurality of impurity projections corresponding to the a-shape. The hybrid convex portion is a supersonic fusion line. The molten concave is used as an ultrasonic sound-sink, and the spliced convex portion is aged and spliced into the concave portion by ultrasonic waves, and the fused convex portion and the concave portion are mutually n. The positioning portion of the layup is formed at the edge of the joint surface and above the joint surface for aligning the reflective sheet with the joint surface of the frame. A recess in the frame is formed on one side of the joint surface, and the lamp tube is connected to the frame through the recess. [Embodiment] In a preferred embodiment, the present invention provides a light source module structure capable of effectively fixing a reflective sheet to a frame and a lamp holder thereof. Xiaojia embodiment: The light source module structure is used for the backlight module in the display device. For example, the 'display device' includes the home TV, the personal computer and the lap of the brain, the mobile phone and the display screen of the digital axis machine. It is decorated in a single shot. The structure of the light source module can also be used by the kanban board and other devices. 1341913 FIG. 2a is a schematic diagram showing the structure of a light source module according to an embodiment of the invention. Figure 2b is an exploded view of Figure 2a. As shown in the figure, the light source module structure of the embodiment includes a light source module 30 and a lamp holder 40. The lamp holder 40 includes a frame body 42 and a reflection sheet 44 attached to the frame body 42. The light source module 30 includes a plurality of lamps 3〇1, and the tube 301 is connected to the frame 42. Fig. 3a is a partial view of one side of the lamp holder 4 of the light source module structure. As shown, the frame 42 of the lamp holder 40 has a joint surface 421, and the reflection sheet 44 has a fusion projection 442. Fig. 3b is a partially enlarged schematic view of the reflection sheet 44. As shown in the figure, in this embodiment, the plurality of fusion ribs 442 have the shape of elongated ribs on the surface of the reflection sheet 44 and on the edge, substantially parallel or perpendicular to each other, however, other implementations For example, the elongated welded convex portion may also be disposed obliquely to the edge of the reflective sheet. Further, the welded projections may have other shapes such as a --shaped bump or a square bump. Fig. & is a schematic diagram of the flow of the super-chopped oscillation welding of the present embodiment. The fusion-welded convex portion 442 is used as an ultrasonic welding wire, and is coupled to the frame 42 via a core of ultrasonic super-connection. The wire-bonding convex portion 442 is heated and melted on the joint surface 421 of the frame body 42, and after cooling, the reflection sheet 44 can be fixedly coupled to the frame body. The ultrasonic oscillating process is preferably performed in a direction perpendicular to the joint face 42 of the frame 42 and the direction of the reflection sheet 44. Further, the material of the frame 42 and the reflection 44 of the lamp holder 4G of the present invention includes a plastic such as PET or PC. Continuing to refer to ϋ 3a, in the case of the step, the 420 has a portion 423 disposed along the edge of the frame 42; in fact, the positioning portion 423 of the embodiment is high on the edge of the frame 42. The edge of the joint surface 42 of the frame 42 is convex 7 1341913. When the reflection sheet 44 is placed on the joint surface 421, the positioning portion 423 abuts against the edge of the reflection sheet 44, and the reflection sheet 44 is restricted from moving relative to the joint surface 421. This makes it easier for the reflection sheet 44 to be aligned with the joint surface 421 of the frame body 42 for ultrasonic fusion bonding. The shape and position of the positioning portion 423 are not limited. For example, the positioning portion 423 may have a shape of a stud, and the positioning portion 423 may be disposed at a corner of the joint surface 421 in other embodiments. In addition, a plurality of notches 425 are formed on the side of the joint surface 421 of the frame 42 in the present embodiment, so that the lamp tube 3〇1 (see FIG. 2) extends through the recess 425 and protrudes into the frame body. The notches 444 formed on the reflective sheet are disposed corresponding to the notches 421 of the frame 42 and the notches are matched to each other. FIG. 3d is a partial, partial schematic view of the lamp holder 5 of the light source module structure of another embodiment. Similar to the embodiment of FIG. 3a and FIG. 3b, the lamp g frame 50 of the present embodiment also has a frame body 52 and a reflection piece % having a fusion convex portion 542; the frame body 52 has an engagement surface 52, a positioning portion cut and a notch 525. . Different from the embodiment of Fig. 6, the joint surface 521 of the frame body 52 of the present embodiment has a splicing recess. P 527. FIG. 3e is a partially enlarged schematic view of the frame 52 of the embodiment. It can be seen that 'the plurality of elongated groove-shaped fusion recesses 527 are parallel or perpendicular to each other on the joint surface 521; however, in other embodiments The long-shaped dazzling concave portion can also be obliquely oriented to the direction of the edge of the reflecting sheet. Actually, the long groove-shaped refining concave portion S27 is inspected and occupied, and the ore should be combined with the reflecting sheet ^ to have a long shape. A plurality of fused convex portions 542 having a rib shape; therefore, when the reflection sheet 合 f is joined to the joint surface of the frame 52, the fusion convex portion 542 is positioned at a position corresponding to the fusion concave concave β 527 and can be joined to each other. Figure 1 is a schematic diagram of the flow of the 1341913 ^ wave shock in this embodiment. The convex portion 542 is a supersonic wrap recess 527 as a supersonic wrap. The ultrasonic wave is formed in the groove of the concave portion 527, and the joint surface 521 of the base 52 and the reflection sheet 54 can be fixed and fixed. The process of ultrasonic tremor is preferably performed perpendicularly to the joint surface 521 of the frame 52 and the direction of the reflection sheet 54. Further, the material of the frame 52 and the reflection sheet 54 of the lamp holder % of the present invention includes plastics such as PET or pc.

Further, the volume of the welded concave portion is at least equal to the volume of the welded convex portion, and preferably the volume of the welded concave portion is larger than the volume of the welded convex portion in the welded concave portion. When the welding is performed by the ultrasonic wave method, the welded convex portion is oscillated in the welded concave portion and the region is expanded to the welded concave portion. After the reduction and cooling, the refining convex portion and the refining concave portion can be joined and fixed.
