Example Embodiment
[0024] Example 1
[0025] like Figures 1 to 3 As shown, a liquid crystal display device includes an LED backlight module, the LED backlight module includes a light source fixing device 2 for fixing the LED32 light bar, a light guide plate 4 opposite to the LED32 light bar, and the fixing device for the light source 2 of the backplane 1. The bottom surface of the light source fixing device 2 in contact with the back plate 1 is provided with heat dissipation fins 21 , and the shape of the fins may be a sheet shape or a column shape or other shapes. Correspondingly, fin insertion holes 11 are formed in the accommodating grooves 12 of the backplane 1 corresponding to the heat dissipation fins 21 , and the heat dissipation fins 21 are exposed to the LED backlight module through the fin insertion holes 11 on the backplane 1 . external. The light source fixing device can be made of a metal material with good heat dissipation performance such as aluminum extrusion, which can effec...

[0027] Embodiment 2
[0028] like Figures 4 to 6 As shown, a liquid crystal display device includes an LED backlight module, the LED backlight module includes a light source fixing device 2 for fixing the LED32 light bar, a light guide plate 4 opposite to the LED32 light bar, and the fixing device for the light source 2 of the backplane 1. The bottom surface of the light source fixing device 2 in contact with the back plate 1 is provided with heat dissipation fins 21 , and the shape of the fins may be sheet-like or column-like or other shapes. Correspondingly, fin insertion holes 11 are formed in the accommodating grooves 12 of the backplane 1 corresponding to the heat dissipation fins 21 , and the heat dissipation fins 21 are exposed to the LED backlight module through the fin insertion holes 11 on the backplane 1 . external. Of course, it is also within the protection scope of the present invention that the heat dissipation fins 21 are not exposed.
