Description of the invention: [Technical field of the invention] The invention relates to a method for producing limbs of a side-light type backlight module and a reflection of a basin lamp D', especially a lamp reflector using a PE material as a plate body System and its structure: [Previous technology] Press, generally used in the liquid crystal display of the fund, the actual design of the government photo. The choice is to use the direct-lit or edge-lit backlight module architecture; - The second diagram is a schematic diagram of the basic structure of the one-side optical backlight module. The basin is mainly provided with a light source 2 in a lamp reflector made of metal, and the side of the reflector 1 is formed. - Opening π ii, the opening σ ii can be inserted into the light guide plate 3 and other related objects, so that the light of the light source 2 can be incident into the light guide plate 3 in the direction of the self-injection, and then emitted from the light exit surface of the light guide plate 3 In order to achieve the effect of the light source. In addition to being the housing space of the light source 2, the light of the conventional lamp reflector 1 must also have a ship that reflects the light of the light source, and the light of the gift wire can be projected toward the intended exit direction, and the light reflects m itself. It is composed of a reflector with a light-like action (such as metal), and in order to further increase the reflection effect on the light, some of the manufacturers will make a reflection of H i or a high-light-reflecting substance. The reflective layer 12; however, since the lamp reflector system is made of metal, the metal is not only heavy in weight, but the price is high, and due to the rigidity of the metal itself, there are many processing procedures. The result is that the lamp reflector 1 has a higher cost in the backlight module and the absence of the total weight of the backlight module. 200938313 In view of the fact that the lamp reflector of the current backlight module has the above-mentioned defects, it is urgent to solve the problem of how to make and reduce the weight and cost of the lamp (4) to provide subsequent utilization. Question. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for producing a lamp reflection 3 in an edge-lit backlight module. The limb is mainly composed of a highly disproportionate substance. It is difficult to form by _, wherein the plate is only heated and softened (traditional heater, high frequency and ultrasonic wave, etc.) at the bent shape, so that the plate towel has a heating place Age, made into a mask to bend it, and finally cut it into a shot length, which can effectively save the heating and cooling time 'and reduce the heating area of the sheet to avoid deformation of the sheet due to comprehensive heat Missing. Another object of the present invention is to provide a lamp reflector for use in an edge-lit backlight module. The lamp reflector is made of PE#f, and the lamp reflector is formed with an opening-side. 'The open-side light source is placed, and a layer-level light-reflecting substance is coated or bonded inside the lamp reflector. £: The plasticity of the material is used to make the lamp reflector, which can effectively reduce the weight of the lamp reflector and achieve the effect of reducing the manufacturing cost and taking advantage of its special characteristics to improve the reflection power (thermoplastic molding). [Embodiment] In order to make it easier for the examiner to understand the manufacturing method and structure of the present invention and the effects that can be achieved by 200938313, the following description is given as follows: First, the taste is shown in FIG. In the manufacturing flow chart, the plate 4 is a flaky shape made of PE#, and the surface of the plate 4 is coated or bonded with a highly radioactive substance 5, and the limb system is first set with a secret and a surface. The sheet 4 made of the PE material having the high-reflection material 5 is placed in the leveling area 61 in the mold 6 to be leveled. Then, the punching machine 62 is used to punch the position hole 41' on the surface of the sheet 4. Then, the plate 4 is sent to the heating zone 63, wherein the mold of the heating zone 6 103 is provided with a 633, and the heating body 633 is disposed on any surface of the plate 4 to be bent and formed. The heating body 6 3 1 heats the sheet 4 to be bent and formed, so that the sheet is twisted by the high temperature, and then the two sides of the sheet 4 are bent and bent by the molding die 64, and finally, after molding. The lamp reflector 4 is cut to a suitable length by a cutter 65, that is, the lamp reflection H4 is completed. Referring to FIG. 4, when the present invention is implemented, the heating body 6 31 of the heating zone 6 ® 3 of the mold 6 can be disposed on the outer side of the plate 4 to be bent and formed, or as shown in Fig. 5. The heating body 6 31 of the heating zone 63 is disposed on the inner side of the sheet 4 to be bent and formed, and by heating the bent portion of the sheet 4 with the heating body 61, the sheet 4 can be softened by heat. And having plasticity, the molding die 64 is used to bend the two sides of the plate 4 into a lamp reflector 4', which is finally cooled and cut to an appropriate length. Referring to FIG. 6 '7, the lamp reflector 4 of the present invention is made of 200938313 PE material, and a light-reflecting substance 5 is coated or laminated on the lamp reflector 4, According to the above method, the PE material plate is shaped as a lamp reflector 4', and the lamp reflector 4 has an opening σ42, and the opening % 2 is available for the lamp source 7 (such as a cold cathode lamp tube, LED). The concentrating rod and the LED illuminating source are disposed in the lamp reflector 4', and the opening 42 is provided for the object of the panel of the light guide plate 8 and the like, and the lamp reflector 4' can be operated by the positioning hole 4 Located in the backlight module, 'by this', the light of the light source 7 can be injected into the light guide plate 8 from the direction of the turn-out, and then emitted by the light-emitting surface of the light guide plate 8 to achieve the effect of the light output. The effect of the present invention is that any surface of the sheet material 4 made of SPE material is to be bent into 31 places to heat the portion by the heating body 633, and then thermoformed by the molding die 6, thereby reducing the Filling the heated area of 4, the research will avoid the lack of deformation of the sheet 4 due to the comprehensive heating, and the heating body 0 3 will only heat the part of the sheet 4, which can effectively save the cost of heating energy, and can Reducing the temperature of the cooling _ 'and accelerating the forming speed of the lamp reflector 4', thereby improving the efficiency of the production of raw ginseng: in addition, since the heating body 63 丨 is locally heated on either side of the sheet 4, 可The fine mold 64 ship can improve the mold/lack of use and use its thermoplastic type to make the light reflection H4' of the light source 7 of the backlight module not only effectively light source 7 The light is reflected into the light guide plate 8, and the weight of the lamp reflector 4 can be effectively reduced, and the cost is also lower than that of the metal, thereby achieving the four effects of mass production and cost reduction. As described in Table τ', the present invention utilizes the above-described lamp reflector manufacturing method and its lamp anti-200938313 (2) 'can indeed achieve the purpose and effect of the claim, and is industrially useful, and has The approval requirements for novelty and progressiveness, and the application for inventions in accordance with the law are promptly filed, and the review committee is also inspected and approved for the approval of patents.
