Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of Straight-down type liquid crystal television of variable light mixing distance, including:For installing liquid crystal
The front housing 1 of display screen;Set on 1 rear of front housing, the middle shell 2 that is connected in front housing 1;Set on the lower section of middle shell 2, be connected in middle shell 2
Rear shell 3;Mainboard 4 and power panel between middle shell 2 and rear shell 3, that be fixed on middle 2 back of shell;It is fixed under front housing 1
The curved support base 11 for being used to support LCD TV of square both sides;And in middle shell 2, backlight for sending out light efficiency
Source, the backlight include:Lamp bar 7 in middle shell 2;The LED light being fixed in lamp bar 7;Cover at the lens in LED light;
Diffuser plate 6 in middle shell 2;Optical diaphragm 10 on diffuser plate 6;By various forms of LED light and lens, by one
Set pattern rule scheme is arranged, the backlight of mixing composition LCD TV, according to LED light and lens arrangement mode synchronous adjustment liquid
Shell 2 and the shape and structure of rear shell 3 in brilliant TV.
Further, two or more lens and the LED light with lens-adapter are installed, which is divided into lamp bar 7
8 two kinds of refraction type lens 9 and reflective lens, 2 subregion of middle shell use refraction type lens 9, and 2 another part region of middle shell is adopted
With reflective lens 8, and middle shell 2 is equipped with reflector plate 5 close to the side of diffuser plate 6.
Specifically, the light that refraction type lens 9 are sent out directly emits toward 6 direction of diffuser plate at an angle, through optical film
It is uniformly spread after piece 10, and the light that reflective lens 8 are sent out is then at an angle after reflector plate 5, via reflector plate 5
Emit to diffuser plate 6 after reflection, is uniformly spread using optical diaphragm 10.
Further, arrangement of the lamp bar 7 on mainboard 4 is the horizontally-arranged of rule, vertical setting of types or inclination arrangement.
Specifically, arrangement of the lamp bar 7 on mainboard 4 excessive face shape of shell 2 in is adjusted.
Further, 3 shape of rear shell and middle shell 2 region shape that leaks outside are consistent, and the light mixing distance ranges of lens is located at 10 ~
In 40mm, requirement of the refraction type lens 9 with reflective lens 8 to light mixing distance is different so that refraction type lens 9 with it is reflective
Not in the same plane, middle shell 2 arrives the difference of 6 distance of diffuser plate with rear shell 3 to lens 8 according to refraction type lens 9 and reflective lens 8
The different shape and structure come shell 2 and rear shell 3 in adjusting.
Specifically, the requirement by refraction type lens 9 with reflective lens 8 to light mixing distance is inconsistent so that LED light arrives
The distance of diffuser plate 6 is inconsistent, so as to the shape and structure of shell 2 and rear shell 3 in adjusting so that save a large amount of internal junction
Conformational space, and then be conducive to the arrangement assembling of complete machine structure part and mainboard 4, power panel, making TV integrally seems more mellow and fuller, fine
It is thin.
In conclusion backlight is pressed by using refraction type lens 9 and reflective lens 8 and the LED light being adapted to therewith
Arrange according to certain rule, the backlight of mixing composition LCD TV, refraction type lens 9 and reflective lens 8 to mixed light away from
From requirement it is inconsistent so that the distance of LED light to diffuser plate 6 is inconsistent, so as to pass through middle shell 2 and rear shell 3 to diffusion
The difference of 6 distance of plate makes different complete machine appearances, such as circular arc, spherical come the shape and structure of shell 2 and rear shell 3 in adjusting,
Achieve the purpose that middle shell 2 and rear shell 3 link up smoothly, and save a large amount of internal structural space, be conducive to complete machine structure part and
The arrangement of the larger component such as mainboard 4, power panel assembles, and solves that conventional Straight-down type liquid crystal television complete machine is thick, moulding is lofty, outer
Sight seem heavy, transition segment difference the problems such as, can effectively produce that moulding is changeable, complete machine is mellow and full and relatively slim straight-down negative
LCD TV improves the aesthetics of product.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect range.
