As shown in Figure 1 and Figure 2, traditional direct-light type LED backlight module comprises: backboard 10, LED lamp bar 20, and this LED lamp bar is fixed on backboard; It is not shown in the figures that LED lamp bar 20 comprises multiple LED() and substrate 201, this substrate 201 is PCB, and each LED is connected by scolding tin with substrate 201; Multiple secondary lens 202, the LED one_to_one corresponding in each secondary lens and LED lamp bar 20 is installed; Each LED is placed in the concave shaped portion of the bottom center position of corresponding secondary lens respectively; One reflector plate 30, is affixed setting with LED lamp bar 20, and on reflector plate, the position of corresponding each LED and the position of described secondary lens are provided with perforate, makes secondary lens pass reflector plate and carries out leaded light; Diffuser plate 40 is set above reflector plate 30, and optical diaphragm group 50 is set on diffuser plate 40, and above-mentioned parts encapsulate by glue frame 60.
When direct-light type LED backlight module is assembled, screw 210 or plastic fixtures 220 is usually used LED lamp bar 20 to be fixed on backboard 10.But use screw or plastic fixtures all can because of have employed extra fixed part add assembling man-hour cause production efficiency low, the fixed part simultaneously increased also can cause the cost increase of backlight module.
Summary of the invention
Goal of the invention: being installed on the assembling procedure of backboard in order to simplify LED lamp bar, saving man-hour and reducing the cost of backlight module.
Technical scheme: in order to reach foregoing invention object, the invention provides a kind of direct-light type LED backlight module, comprising: a backboard; Some LED lamp bar, described LED lamp bar is fixed on described backboard; Described LED lamp bar is provided with at least one group of opening and protuberance, and be provided with on described backboard and the opening of described LED lamp bar host cavity one to one, the size of the size of this host cavity and the protuberance of described LED lamp bar matches, and protuberance can snap onto in host cavity.
Further, the width of described host cavity is less than the width of the opening of LED lamp bar;
Further, also comprise the barrier rib being arranged on described lamp bar end, skid off to prevent lamp bar;
Further, arrange one at the top of the host cavity of described backboard to the little convex closure structure of host cavity sunken inside, and be provided with a gate button at the protuberance of described LED lamp bar; This gate button carries out mating with described little convex closure structure and fastens;
Further, be metal or plastics in the material of described backboard.
Beneficial effect: by the engaging of the host cavity on backboard with the protuberance in LED lamp bar, makes LED lamp bar be fixed on backboard, namely saves the fixed part of screw of the prior art or plastic fixtures, simplifies the assembling procedure that LED lamp bar is installed on backboard; Again reduce the cost of the backlight module that the fixed part because increasing produces.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
The LED lamp bar and the backboard that the present invention is directed to the direct-light type LED backlight module of prior art have done further improvement.As shown in Fig. 3 to Fig. 7, the direct-light type LED backlight module that The present invention gives the first embodiment comprises, backboard 500, and the material of backboard can be metal or plastic material; LED lamp bar 300, this LED lamp bar 300 is fixed on backboard 500.Wherein, lamp bar 300 comprises: multiple LED(is not shown in the figures); Multiple secondary lens 302, the LED one_to_one corresponding in each secondary lens and LED lamp bar is installed; And substrate 301, this substrate 301 is PCB.Wherein, at least one group of opening 303 and protuberance 304 is provided with at substrate 301.And be provided with on described backboard and the opening 303 of described LED lamp bar host cavity 501 one to one, the width w of host cavity 501 is less than the width W of the opening 303 of substrate, protuberance 304 on the size of host cavity 501 and substrate matches, and protuberance can snap onto in host cavity.
When lamp bar 300 is fixed on backboard 500, host cavity 501 on backboard to be placed in the opening 303 on corresponding lamp bar substrate as shown in Figure 6, again the protuberance 304 on lamp bar 300 is pushed in the host cavity of backboard, as shown in Figure 7, so namely complete the assembling of to be fixed on by lamp bar on backboard.Meanwhile, in order to prevent lamp bar from skidding off.And a barrier rib 700 is set on the relative position of lamp bar end and backboard, as shown in Figure 3.
By the engaging of the host cavity on backboard with the protuberance in LED lamp bar, making LED lamp bar be fixed on backboard, namely save the fixed part of screw of the prior art or plastic fixtures, again reducing the cost of the backlight module that the fixed part because increasing produces.
In order to the retain strength that the host cavity improved on backboard mates with the protuberance on pcb board, The present invention gives the second embodiment, uniquely arrange one to the little convex closure structure 502 of host cavity sunken inside unlike the top of the host cavity on backboard with the first embodiment.And the protuberance on the substrate of LED lamp bar is provided with a gate button 305 as shown in Figure 8, pushes in the host cavity of backboard by the protuberance on lamp bar, this gate button carries out mating with the little concave point on backboard and fastens as shown in Figure 9, to reach the effect be fastened.Meanwhile, the barrier rib preventing lamp bar from skidding off can also be saved.The feature of the miscellaneous part of the present embodiment is identical with the first embodiment, therefore not proudly states.
