The invention relates to a fixing device of a back light module lamp tube and a back light module with a lamp tube fixing device, and the purpose is to improve the problems caused by welding and turning on and turning off machine. The fixing device comprises a fixing seat, two guide vanes, two drive vanes and a switch seat, a back board provided with an opening is arranged on the circuit board of the back light module, one end of the fixing seat gets through the opening and connects with the circuit board, a supporting groove for containing the lamp tube is arranged at the other end, two perforating holes are arranged on the supporting groove, and the both perforating holes perforate to the bottom part of the fixing seat; the both guide vanes are respectively provided with a first side edge and a second side edge, a conducting wire is arranged between the first side edges, and the first side edges are connected respectively with the circuit board through the both perforating holes; the both drive vanes are arranged on the both outer sides of the both second side edges; when the switch seat is combined with the fixing seat, the both drive vanes are driven and the both guide vanes are driven, and thus the first side edges fix the conducting wire of the lamp tube.
Description
technical field [0001] The invention relates to a fixing device for a lamp tube of a backlight module and a backlight module with the lamp tube fixing device. Background technique [0002] With the advancement of science and technology, various information products such as mobile phones, notebook computers, digital cameras, PDAs, LCD screens and other products are becoming more and more popular, which greatly increases the demand for LCD displays. Only the setting of a backlight source can be displayed, and the backlight module is mainly used as the backlight source of the liquid crystal display. [0003] The backlight module includes a circuit board, at least one light source, a reflector, a diffuser plate, etc. The light source used today includes a cold cathode fluorescent lamp (Cold Cathode Fluorescent Lamp; CCFL), an external electrode fluorescent lamp (External Electrode Fluorescent Lamp) EEFL) or Light Emitted Diode (Light Emitted Diode; LED), wherein the circuit boa...
