New Description: [New Technology Field] This creation is about backlight modules, especially one that uses a light-emitting diode as a light source, and directly integrates components such as light-emitting diodes and metal lines into a backlight module. The lampshade of the group can speed up the overall production efficiency of the backlight module, and save the circuit board component originally used by the backlight module of the conventional light-emitting diode. [Prior Art] According to the conventional backlight module used on the LCD screen, most of the cold cathode fluorescent lamps (CCFLs) are used as the light source. However, due to the light-emitting process of the cold cathode tubes, mercury vapor is required. As a discharge medium, mercury can cause harm to the human body and the environment. Therefore, in the Restriction of the use certain Hazardous Substance, mercury has been identified as a banned substance, so that the lamp containing the cold cathode tube containing mercury , can not be sold in the EU region, therefore, in order to solve the above problems, the industry is not committed to the development of new light-emitting components, in which the light-emitting diode (LED) does not need to use mercury, and itself It has the advantages of low power consumption, long life, no need for warm-up time and fast response, so it can meet the environmental regulations of most countries, and can greatly improve the convenience of use. In addition, the light-emitting diodes The volume can also be made very small, so in today's electronic products are pursuing the "light and thin" design concept, Photo-diode has become an backlight module, the light emitting element is indispensable. As shown in FIG. 1 , a backlight module J having a light-emitting diode includes a metal lamp cover 11 and a light-emitting portion 13 , wherein one of the metal lamp cover is recessed with a receiving groove 110 The light-emitting portion 13 can be accommodated in the accommodating groove 11 ,, and the light source emitted from the light-emitting portion 13 can be reflected from the accommodating groove 11 by the reflection effect of the inner surface of the accommodating groove 11 〇 The light emitting portion 13 is a light emitting diode (LED Light Bar), and includes a circuit substrate 131, a plurality of layers of adhesive 132, a metal line 133, and at least one light emitting diode 135. The metal line 133 is coated on one side of the circuit board 131 by the adhesive 132, and subjected to exposure, development, etching, etc. to form a circuit board, and the light-emitting diodes 135 are assembled to the same. The circuit board 131 is connected (eg, soldered) to the metal line 133 to receive the current from the metal line 133 and emit light. Finally, the circuit board 131 is fixed to the circuit board 131 by the adhesive 132. The accommodating slot no to avoid sway or displacement Affect the overall quality of the light emission of the backlight module 1, so that the light emitting source can be a backlight module of the liquid crystal screen. However, as shown in Fig. 1, since the light-emitting diode 135 emits a large amount of heat when it emits light, when the heat dissipation effect of the backlight module is not good, the inside of the metal lamp cover 11 is caused. The temperature of the space is too high, and the components (such as the light guide plate) adjacent to the light-emitting diodes 135 are prone to aging, and the light-emitting diodes 135 are also easily damaged by high temperature, but the conventional circuit substrate 131 is effective in isolating the current to avoid the short circuit phenomenon, so it is usually made of plastic or resin material without good thermal conductivity, so that the heat generated by the light-emitting diodes 135 must pass through the adhesive 132 in sequence. The circuit board 131 and the other adhesive 132 are transferred to the metal lamp cover η, so that the heat dissipation efficiency of the whole module 1 of the backlight M378404 is not good. In the above manufacturing method, the metal lamp cover 11 and the light-emitting portion 13 are respectively Manufacture and assembly, therefore, the manufacturer must use the backlight module 1; the same production line produces the metal shade 11 and the light-emitting portion 13' and transports the metal lamp to the light-emitting portion. The cost, as well as the cost of the metal shade 11 and the light-emitting portion 13 and the warehouse space, increase the overall cost of the backlight age 1 and prolong the production time of the back-wire assembly. Therefore, how to design the -__ back group to solve the above problems has become an important issue for the relevant backlight module manufacturers. [New content] In view of the traditional backlight module using the light-emitting diode, there are problems such as difficulty in heat dissipation and low production efficiency. The problem of aging of the components of the wire-backed backlight module and the long production process are so long. Long-term efforts and research '·Development of the spine-type-light-emitting diode backlight module' is based on Lin, and can effectively solve the above problems. One of the purposes of this creation is to provide an integrated backlight module for a light-emitting diode, which is mainly used in the production process to integrally manufacture the lamp cover portion and the light-emitting portion to save material and shorten the overall backlight module. During the production time, the backlight module includes a lamp cover portion having a cross-sectional shape, and one side of the lamp cover portion is formed with a receiving groove, and the light-emitting portion is received in the receiving groove. The reflection effect of the inner surface of the accommodating groove projects the light source generated by itself from the opening of the accommodating groove, and the illuminating portion includes an insulating thermal conductive adhesive, 5 = metal wiring and at least one light emitting diode, each The light-emitting diode system is respectively connected to the metal line to receive the current from the metal line and emit light. J. The metal line is finely ground on the inner surface of the receiving groove by Wei Yuna. The heat generated by the light-emitting diodes can be quickly guided to the lamp cover portion, thereby greatly simplifying the overall structure and manufacturing procedure of the backlight core group of the light-emitting diodes, thereby effectively improving production efficiency. . Another purpose of the present invention is that the metal circuit is adhered to the lamp cover portion through an insulating thermal conductive adhesive to use the lampshade portion as a circuit substrate, and the short circuit is not generated, so that the conventional light-emitting device can be saved. The base material used in the backlight core group of the polar body has a low production cost of the cake, and the heat generated by the light body is quickly transmitted to the lamp cover portion to pass the large-area lamp cover portion. The heat dissipation greatly improves the overall heat dissipation efficiency of the backlight module. In order to facilitate the review of the purpose of the county, the technical characteristics and its efficacy, do more step-by-step (9) knowledge and understanding, _ example with the schema, detailed description is as follows.

In this way, the light-emitting module 2 can be used to fabricate the light-emitting portion 23 and the lamp cover portion 21 during the production process, so that the operator can be divided into different production lines without being the lamp cover portion 21 or the hairpin, and can be reduced. The cost of dumping each component and storage effectively increases the overall production efficiency of the j-light module 2 and reduces the production cost, and the light-emitting diode _=5 is directly or only transmitted through the insulating heat-conducting 231 to the lampshade portion. Therefore, the heat generated by the month b is quickly transmitted to the shade portion u, thereby greatly improving the heat dissipation effect of the backlight module 2. In addition, in another embodiment of the present invention, if the manufacturer can improve the luminous efficiency of the backlight module, a reflective sheet body is added to the lamp cover portion (for example, a plastic material of saturated multi-vinegar, a plastic having a metal reflective layer) In the case of the material, as shown in FIG. 5, the backlight module 3 includes a lamp cover portion 31 and a "light-emitting portion", and the lamp cover portion 31 is made of a metal sheet body 311 and a reflection sheet body 312. Or the operator can also use the reflective sheet body as the lamp cover portion 31, and the cover portion 31 is recessed with a receiving groove 31〇, and the light-emitting portion 33 includes an insulating thermal conductive adhesive 331 and a metal line 333. At least one light-emitting diode, the metal line 333 is fixed to the inner side surface of the accommodating groove by the insulating guide 33111], and the light-emitting diode 335 is connected to the metal line twist, and the Μ can receive the The current from the metal line 333 emits light. In the case where the reflection sheet body is provided in the shade portion η of the back yarn group 3, the manufacturer removes the green-type process green described in (4), and firstly creates a metal line 333 and a light-emitting diode on the transfer. In addition to the body 335, it can be changed to another process method, that is, the release element in the first process method is replaced by the reflection sheet 312, and the metal line 333 and the light-emitting diode are directly formed on the reflection sheet body 312. 335, and produced the backlight module 3 of the present creation. In this way, since the metal line 333 and the light-emitting diode 335 can be integrally formed on the reflective sheet 312, the material of the circuit substrate in the conventional backlight module can be omitted, and the operator directly in the reflective sheet. After the metal line 333 and the light-emitting diode 335 are formed on the body 312, the reflective sheet body 312 can be adhered to a metal sheet body 311 according to the production design of the product, and punched into a predetermined shape to form the present creation. The lamp cover portion 31, or the reflection sheet body 312 is bent first, and placed in a predetermined shape of the metal sheet body 311 to form the lamp cover portion 31 of the present invention, or the reflection sheet body 312 can be directly used by the manufacturer. The lampshade part 31 of the present invention enables the backlight module of the present invention to have greater industrial utilization to enhance the market competitiveness of the industry. Furthermore, in still another embodiment of the present invention, the manufacturer can also change the manner in which the reflective sheet and the metal sheet are joined to form another type of shade portion. Please refer to FIG. 6 for the backlight module 4 The lamp cover portion 41 is formed by a metal plate body 411 and a reflective sheet body 412. One side of the metal plate body 411 is recessed with a receiving groove 41? The light-emitting portion 43 includes an insulating thermal conductive adhesive 431, a metal wiring 433, and at least one light-emitting diode 435. The metal wiring 433 is fixed to the inner surface of the metal foil body 4 by the insulating thermal conductive adhesive 431, and each of the light-emitting portions The diode 435 is still connected to the metal line 433, and the reflective sheet 412 is received in the receiving groove 41, and a hole 4120 is disposed at a position corresponding to the light emitting diode 435 for the light emitting The polar body 435 passes through 'and reflects the light emitted by the light-emitting diode 435. Thus, the light-emitting portion 43 can transfer its own heat to the metal sheet body 411' with a quick filling and has a good reflection effect. In summary, it can be seen that 'there is no additional use of the circuit board on the inventive backlight module, so 'the following advantages can be obtained: 0) The lamp cover portion and the light-emitting portion are difficult to make, the large towel! Simplify the f-mode The overall structure and production process of the group' further improve the overall production efficiency of the group; (2) The light-emitting part does not need to use the circuit board, which effectively reduces the production cost; (3) The manufacturer does not need to divide the production line for the lampshade part and the light-emitting part. (4) The operator does not need to additionally plan to store the storage space of the lamp cover, the light-emitting part and the like separately; and (5) the heat of the light-emitting diode can be quickly transmitted to the lamp cover portion, thereby improving the overall heat dissipation efficiency of the backlight module. ° In this special - mentioning that the metal line of this creation is attached to the material department, the industry can be connected to the metal line by the wire, flexible circuit board or other line configuration to supply power. To the metal line, there are a variety of connection methods 'not here--(four), but regardless of the circuit configuration method M378404 method' as long as the metal line can receive the power, and the received power is transmitted to the light-emitting diode , which is the metal circuit described in this creation. According to the above, it is only the solid face of this creation, but 'Benna’s range in Zhangzhi Lake is not awkward. Here, 'following the person who is familiar with the subject, 镰本_Uncovered the technology inside the valley' Equivalent changes that can be easily considered are not subject to the protection of this creation.
