Certainly, heat insulating strip can also use other not heat conduction or the low and material with shockproof cushioning character of coefficient of heat conductivity to make, and do not repeat them here, but its application all should within protection scope of the present invention.
In the present embodiment, preferably, described frame 6 is metal frame, and described lamp bar 3 is LED(light emitting diode) lamp bar.
Certainly, the material of face frame can also adopt other materials to make according to different demand, and lamp bar also can be the lamp bar of other types, and such as, face frame can also be plastic cover frame, does not repeat them here, but its application all should within protection scope of the present invention.
Preferably, described conducting strip 8 is made up of the flexible material with thermal conductivity.
In the present embodiment, preferably, described conducting strip 8 is graphite heat-conducting fin.
Certainly, conducting strip also can select other flexible materials with thermal conductivity to make, and such as: heat-conducting silica gel sheet or heat-conducting pad etc., do not repeat them here, but its application all should within protection scope of the present invention.
For straight-down negative structure, LED is directly attached on backboard under reflector plate, backboard is metal material, and its heat conductivility is better, as shown in Figure 6, in the outside of the backboard contacted with glue frame and the outside of glue frame, attach whole piece graphite heat-conducting fin, the partial heat that lamp bar is produced is transmitted to face frame via backboard, graphite heat-conducting fin, is shed by face frame, because face frame and backboard are similarly metal material in the present embodiment, can further improve the radiating effect of directly-down liquid crystal module.
Embodiment three:
Present embodiments provide a kind of televisor, comprise side-light type liquid crystal module or directly-down liquid crystal module that above-mentioned any embodiment provides.
The television structure that the present embodiment provides is all not shown in the accompanying drawings, it has good heat dispersion, in side-light type liquid crystal module, conducting strip is set, and this conducting strip is combined with the aluminium heat sink that backboard is now applied use, effectively the net quantity of heat that LED lamp bar produces is passed through backboard, glue frame and face frame conduct, enhance radiating effect, and then ensure that luminosity and the serviceable life of lamp bar, the light guide plate etc. avoided around lamp bar occurs being heated the phenomenon of softening transform, extend the serviceable life of televisor, and while not increasing televisor thickness, ensure that the image quality of televisor, and then ensure that viewing effect, for user provides better visual, improve the market competitiveness.
In order to cater to the market demand, improve the market competitiveness, most producer can not use fore shell, and direct employing face frame replaces fore shell, or does not use face frame, directly adopts fore shell to replace face frame.
Therefore, in the televisor that the present embodiment provides, described fore shell and face frame can be used as same component, and namely described frame is described fore shell.Such as: when televisor comprises side-light type liquid crystal module, then do not use fore shell, direct use face frame is as fore shell; When televisor comprises directly-down liquid crystal module, then do not use face frame, directly use fore shell etc., do not repeat them here, but its application all should within protection scope of the present invention.
Certainly, face frame and fore shell also can be two different components, are fixedly connected with by face frame during use with fore shell, and the use for face frame and fore shell can be selected according to different situations and demand, does not repeat them here.
It should be noted that, because heat trnasfer causes because temperature in system or in object is different, and the spontaneous transmission of heat is always delivered to low-temperature space by high-temperature region, the heat that lamp bar sends can be dispersed around the cylinder being axle with lamp bar to different directions, and glue frame has two kinds of set-up modes in liquid crystal module, one is arranged on various blooming piece, another kind is arranged under various blooming piece, play the effect of fixing back light system, what all adopt in above-mentioned any embodiment is the mode that glue frame is arranged on blooming piece, but adopt no matter which kind of set-up mode, the technical scheme that above-mentioned any embodiment provides can be adopted, the net quantity of heat that lamp bar produces is conducted from backboard and backboard opposite side both direction, solve the heat dissipation problem of lamp bar, do not repeat them here, but its application all should within protection scope of the present invention.
In the present invention, term " first ", " second ", " the 3rd ", " the 4th ", " the 5th " object only for describing, and instruction or hint relative importance can not be interpreted as; Unless otherwise clearly defined and limited, term " multiple " refers to two or more, and the term such as term " installation ", " being connected ", " connection ", " fixing " all should be interpreted broadly, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
