Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects of the existing known backlight module, and provide a new structure of the backlight module and its lamp device. The technical problems to be solved are used to solve the existing conventional backlight module. In order to increase the firmness of the lamp device directly fixed on the backboard, it is necessary to use the lamp fixing element again, resulting in a lot of labor hours for assembly and a lack of cost, which is more suitable for practical use

Embodiment Construction

[0035] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, Features and their functions are described in detail below.

[0036] First, please refer to FIG. 1 , the present invention relates to a lamp device used in a backlight module. The lamp device 10 includes a printed circuit board 11 , a U-shaped lamp 12 and a supporting plate 13 . The printed circuit board 11 further includes a connecting base 111 , and the supporting board 13 is a thin board.

[0037] Please refer to FIG. 1 again. First, one end of a U-shaped lamp tube 12 is connected and arranged on the surface of the printed circuit board 11. More specifically, one end of the U-shaped lamp tube 12 is fixed to the printed circuit board 11 by welding. Furthermore, the other end of the U-shaped lamp tube 12 is fixed on th...

Abstract

The invention relates to a back light module and relative tube, wherein the tube comprises one printed circuit board, one U-shaped tube or straight tube, one support plate or another printed circuit board; another surface of printed circuit board also comprises connecting plug that welding one end of U-shape tube or straight tube on the surface of printed circuit board; then fixing another end on the surface of support plate or anther printed circuit board; the connecting base can connect power source to supply electricity to the tube, when the following tube is used in the back light module, to supply needed light source. Since the back plate of back light module has dual holes, and the connecting base can be arranged through said holes to mount the tube on the back light module without tube fixing element.

Description

technical field [0001] The present invention relates to a backlight module and its lamp device, in particular to a backlight module and its lamp device which are fixed in a modularized manner and directly arranged on a backboard. Background technique [0002] The existing conventional backlight modules can be roughly classified into two categories according to the arrangement of the lamp tubes on the liquid crystal display device, one is the edge-type backlight module, and the other is the direct-type backlight module. The way to install the light tubes of the group is usually to directly engage or fix the light tubes on the back frame of the backlight module or the reflector, but this method cannot effectively position the light tubes firmly, and this light tube The positioning method makes the lamp tube easy to shift, thus causing light leakage or electric leakage of the backlight module, and because the lamp tube of the backlight device must be replaced in a dust-free env...
