Abstract
The utility model discloses a liquid crystal backlight module heat dissipation structure which comprises an aluminum profile bottom plate. A heat-conducting double-faced adhesive tape mounting plate is arranged on one long side of the aluminum profile bottom plate, an LED lamp bar is mounted on the inner side face of the heat-conducting double-faced adhesive tape mounting plate, and the LED lamp bar and the heat-conducting double-faced adhesive tape mounting plate are fixed through heat-conducting double-faced adhesive tape in a bonding mode. Accordingly, the heat dissipation effect of the LED lamp bar is greatly improved, and the service life of backlight of a high-brightness LCM can be prolonged.
Description
Technical field
The utility model relates to liquid crystal display field, particularly relates to a kind of LCD backlight module radiator structure.
Background technology
Existing LCM(LCD backlight module) base arrangement mostly is punching press galvanized sheet and adds aluminum strip, and LED lamp bar heat conducts on base plate by aluminum strip.This kind of way is because aluminum strip area is less, and between different materials, heat conduction is poor, and radiating rate is slow.For high brightness LCM, radiating efficiency is inadequate.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of LCD backlight module radiator structure, can greatly promote the radiating effect of LED lamp bar, and for the LCM of high brightness, also can improve serviceable life backlight.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LCD backlight module radiator structure is provided, comprise aluminium section bar base plate, a long edge position of described aluminium section bar base plate is provided with bond plies installing plate, the medial surface of described bond plies installing plate is provided with LED lamp bar, between described LED lamp bar and bond plies installing plate, fixes by heat-conducting double-sided glue.
Preferably, described aluminium section bar base plate also offers locating slot near bond plies installing plate place, and described LED lamp bar is installed in locating slot, makes LED lamp bar height consistent with aluminium section bar, is convenient to the installation of outer liquid crystal display screen.
The beneficial effects of the utility model are: the utility model uses aluminium section bar to replace punching press panel beating to make LCM base plate, because the heat-sinking capability of aluminium section bar will be far above galvanized sheet, so greatly promoted radiating effect, and for the LCM of high brightness, also can improve serviceable life backlight.
Brief description of the drawings
Fig. 1 is the perspective view of the utility model LCD backlight module radiator structure one preferred embodiment;
Fig. 2 is the local enlarged diagram of A part in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, aluminium section bar base plate, 2, bond plies installing plate, 3, bond plies, 4, LED lamp bar, 5, locating slot.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of LCD backlight module radiator structure, comprise aluminium section bar base plate 1, a long edge position of described aluminium section bar base plate 1 is provided with bond plies installing plate 2, the medial surface of described bond plies installing plate 2 is provided with LED lamp bar 4, between described LED lamp bar 4 and bond plies installing plate 2, pastes fixing by bond plies 3.
The utility model uses aluminium section bar to replace punching press panel beating to make LCM base plate, due to the dimensional flexibility of aluminium section bar on product cross section, the installation site of LED lamp bar 4 is directly designed on aluminium section bar base plate 1, LED lamp bar 4 directly contacts with aluminium section bar base plate 1 by bond plies 3, by directly outwards heat radiation of aluminium section bar base plate 1, the heat-sinking capability of adding aluminium section bar will be far above galvanized sheet, so greatly promoted radiating effect, for the LCM of high brightness, also can improve serviceable life backlight.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
