Problems solved by technology

[0005] In view of the above-mentioned prior art, the method used to fix the light-emitting unit in the backlight module in the prior art cannot provide a stable combination and reduce the complexity and cost of assembly. Therefore, a light-emitting unit is provided here. The fixing device of the unit and the backlight module using the fixing device aim to firmly fix the light-emitting unit on the backplane in the backlight module, simplify the assembly steps and reduce the use of fixing components such as screws and nuts

Abstract

The back light module includes one back board, several light emitting units arranged on the back board in certain interval; and rigid base boards set between two adjacent light emitting units and with two edges pressing part of the adjacent light emitting units for fixing onto the back board. The rigid base boards fixed onto the back board with screws and nuts are superposed with the parallel arranged light emitting units so as to fix them onto the back board firmly. The light emitting unit fixing device of the present invention is simple and low in cost.

Description

(1) Technical field [0001] The invention relates to a fixing device, in particular to a fixing device for a light-emitting unit in a backlight module. (2) Background technology [0002] In the prior art, in a backlight module in a liquid crystal display, the method for fixing the light-emitting unit (unit) can be referred to figure 1 . The backlight module 1 is mainly composed of a backplane 11 and several light-emitting units 12 arranged in parallel on the backplane 11 at a distance. The aluminum substrate 122; wherein, the light-emitting element 121 is directly welded and assembled on the conductive circuit (not shown in the figure) on the aluminum substrate 122, and the heat energy generated during operation is conducted to the backplane 11 through the aluminum substrate 122 to escape . [0003] Continue to refer to figure 1 , the method used to fix the light-emitting unit 12 in the prior art is to first form several corresponding perforations (not shown in the figure...
