Description of the Invention: [Technical Field] The present invention provides a removable backlight module and a liquid crystal display, in particular, a backlight module and a liquid crystal display, which have a plurality of removable light source groups, and An external electrode tube is used as the light source. [Prior Art] At present, most of the lamps used in the backlight module of the liquid crystal display are Cold Cathode Fluorescent Lamps (CCFLs). The electrode of the lamp is enclosed in the lamp tube, and has a conductive end electrically connected from the inside for connecting with the wire, and then electrically connected to the power source via the wire to light the lamp. The conductive terminals of the cold cathode fluorescent lamp are connected to the wires by soldering or copper tape. However, the way of soldering or copper stripping is complicated, and the rate of defects is very high. In the case of soldering, if the soldering is good, the high temperature generated during the soldering process is sufficient to melt the conductive terminals and the wire connecting portions, the solder, and the road for picking; if it is the solder and the wire connecting portion of the tin If the use of copper tape is used, it is necessary to consider the situation of the copper tape at the four corners of the copper tape. Therefore, it is necessary to add a heat insulation with good insulation effect. The set of S is built on the outside of the copper strip, causing an additional cost burden. To slap the patent 00540745, a backlight device is provided, which is provided in a main body, and the two ends of the lamp tube are respectively claimed. And the main body is provided with a plurality of supporting members, so that the fixing member has a recessed hole for accommodating at least the lamp 邙, and is disposed at the mechanical end of the cavity. Although the patent can be used to solve the aforementioned problem 5 1336795, the requirements for the lamp of the backlight module are increasingly severe, and the electric wattage and usable life are such that there is an external electrode tube or & The "Electrical Electrode Fluorescent Lamp" (EEFL) is available in response to market demand. The electrode tube is a kind of illuminating element that converts light energy into high-frequency discharge. The electrode tube is based on electromagnetic induction. The principle is to use the brake field # which is placed outside the tube, and the electrode generates an induced current in the tube. 'Different from other fluorescent tubes, the Wei is converted into the energy of the tube (10). For the metal electrode, it acts like the primary coil of the transformer, and the effect of s is like the secondary coil of the transformer. In the case of current, the brightness of the light of the external electrode tube is higher than that of the current direction, and in recent years The external electrode tube and its use have been significantly improved, so the external electrode tube has been sourced. This 1, material - high efficiency light and life is about 60,000 hours' and the external electrode lamp The tube is up to the top of the 昱 昱 Λ 在 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 许 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四The products of the external electrode tube, there are still problems in the market, etc. i. Poor renaturation and poor impact resistance The lamps are arranged in parallel with each other on the backplane, and the Shaodian recruits the LCD panel.

Each of the inventable scope of the invention is defined by the scope of the appended claims. [Embodiment] Referring to Figure 1, it is a schematic diagram of a giant liquid crystal display of the present invention. The liquid crystal display 1 includes a backing plate 102, a backlight module 1 (Η, an optical film set (not shown), a liquid crystal panel 108, and an outer frame 丨丨〇. The 101 series is disposed on the backboard 1〇2, and is composed of a plurality of replaceable light source groups 104, a plurality of external electrode tubes 1〇5, and a fixing device 1〇6. In addition, the liquid crystal panel 1〇 8 series are arranged on the fixed device. In order to make the content of the present invention more clear, the technical features of the present invention will be further explained below. 8 cases, ί二ΐΐ明明- It is disposed on the back plate 202, and the surface of the i-module 200-month board 202 is designed with a sadness 206. The group can be additionally designed to correspond to two tracks: two = replaceable, and 207. The second command group 2〇7 series is equipped with the corresponding one for the exchangeable light source group 2〇4 to slide on the back plate ^2.

The demand and characteristics of the 'quantity adjustment, and 4 3 figure shows that the solid device 206 ij is used to fix the removable bungee = ϊ piece so that the exchangeable light source group 204 s each other Leaning away, the exchangeable light source group 204 and the electrode tube 21 thereon are removed. Extract or retract from the backlight module to replace the new external electrode tube (10) for the purpose of wire removal. Further, the fixture 206 can further include a plurality of second receiving portions 216, and the negative portions are disposed between the two adjacent conductive members 214. The second capacitor 216 and the first valley portion are coupled to each other to accommodate the external electrode 230 of the external electrode tube 2. At the same time, the conductive sheet 212 can be designed with a recess for placing the first receiving portion of the 1330795 3 can be disposed outside the external electrode 230 and having the function of a k-power supply connection. The fixing device 206 not only provides the function of the fixed exchangeable light source group 2〇4, but also functions as an electrical connection between the replaceable light source groups 2〇4. For example, the 'removable light source group 204 is transmitted through the screw 218, and the combination is achieved. To correct this, the conductive strips 2 on the adjacent light source group 204 are adjacent to each other so that the external electrode tubes 21G can be connected in parallel with each other, as shown in Figs. 4 and 5, respectively, complying with Figs. 4 and 5, respectively For the two different embodiments of the present invention, the schematic diagram of the straight-lined surface is replaced by a screw 218. Wherein, the conductive element; ^, the vertical plate 'is disposed on the two adjacent removable light source groups, 2 = = conductive 7 " 214 can also be as shown in Figure 5, for the second In order to achieve the same function as the embodiment shown in FIG. 4, the T-shaped conductive member 214 can refer to the corresponding conductive sheet 212, 'to place the external electrode 230 of the external electrode tube 210 to be strong 1 Bungee coating. = Figure 2 shows another design of the fixed replaceable light source group 2〇4. The electrical component 214 is an elastomer 22. It can provide pressure at the contact of the adjacent exchangeable light source group 2Q4. The replaceable light source level of the electrode tube 210 is 2〇4 ^ solid on the moonlight. At the same time, since each of the elastic bodies 220 is electrically connected to the two adjacent conductive sheets 212, the external electrode tubes 21 can be connected in parallel. 22^ can be an arc, but is not limited to this type. In the case of the example, since the elastic force of the elastic body 22Q is utilized, the pressure is combined and fixed. Therefore, it is no longer possible to use the 糸 as disclosed in Figures 4 and 5. In addition, the second track group of the replaceable light source group 2〇4, or the package 13367795 contains more than two convex roads, the first track of the only back plate _ must be corresponding to the design 0 as shown in Fig. 7. 'It is one of the elastomers of the present invention. In the present embodiment, the 'elastomer 22G' is made of a metal plate and is partially provided to provide an appropriate elastic force. Please refer to the δ ^ $ configuration on the two adjacent conductive sheets 212 for electrically connecting the two. Electricity = 212. At the same time, the pole lamps 210 disposed through the elastic body 22 can be connected in parallel with each other due to the external electrodes 23 of the outer tube 121, and the recesses disposed in the recesses of the conductive sheets 212. j 广 丨 另 另 另 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光The buffer 塾 222 can be disposed between the external electrode 230 and the fixture 2〇6, or between the external electrode 230 and the removable light source assembly, or even around the external power, 230 for better impact resistance.
