The light guide plate 10 is atomization light guide plate.In the present embodiment, the light guide plate 10 is by PC and light diffusing agent mixed preparing
After be molded, improve enter light guide plate 10 inside light dispersion effect.It should be noted that the quality percentage of light diffusing agent
Group than content is divided into 2.5-3.5%, it is preferable that uses 3% light diffusing agent.The light guide plate 10 is L-type structure, the light guide plate
10 have vertical portion 11 and the vertically integrated transverse part 12 extended to form forward in bottom end in portion 11, the vertical portion 11 and cross
To portion 12, horizontal extension is arranged in left-right direction, the inside and outside corner of the vertical portion 11 and transverse part 12 be respectively fillet,
Chamfering.
The LED light strip 20 includes FPC plate 21 and several first LED elements 22 being set on FPC plate 21.In this implementation
In example, the LED light strip 20 is provided with one and is "-" type light bar, and the "-" type light bar is arranged in left-right direction, owns
First LED element 22 is disposed with a row along "-" type light bar extending direction.Preferably, all first LED elements 22 are under
It shines.
The FPC plate is set on front side and/or the rear side of vertical portion 11, it is preferable that the FPC plate 21 is set to vertically
The rear side in portion 11.The light of first LED element 22 transmitting is from vertical portion 11 to tripping in light, then rear end through transverse part 12 is forward
Until going out light from the front end face of transverse part 12.
Upper surface, lower end surface, left side, the right side of the transverse part 12, and, leading flank, the rear side of vertical portion 11
Face, top end face, left side, right side are covered with photomask 30.Preferably, the photomask of the lower end surface of the transverse part 12
For black and white double faced adhesive tape, remaining photomask is black and white one side glue.
The front end face of the transverse part 12 is in the gradually small design of the big both sides in center under forward sight state.Preferably, the transverse direction
The top edge of the front end face in portion 12, lower edge are intermediate toward both ends arc gradual design, it is of course also possible to for straight or other
Shape retrieval.By the gradually small design of the big both sides in center, from the center of transverse part 12 at toward two sides gradual change go out light, closer to center
Place, the brightness of presentation is bigger, and the brightness presented closer to the left and right tail end of transverse part 12 is darker, so will be in light-emitting surface
The effect of existing brightness gradual change improves stereovision and spatial impression that light guide plate 10 goes out light.

The inner wall of mounting groove 113 is recessed forward.The FPC plate 21 is installed in FPC plate mounting groove 113, it is preferable that FPC plate 21 is pasted
In on the inner wall of FPC plate mounting groove 113.
In the present embodiment, the upper end side of the FPC plate 21 is extended with a weld part, has row in scolding tin on the weld part
Line 24, it is preferable that enclosed at scolding tin with insulating tape packet one.Several first LED elements 22 being set on FPC plate 21 and one
Two LED elements 23 control work by 24 external controller of winding displacement and the alternate effect of breathing of light and shade are presented in the first LED element 22,
Specifically, there are three types of states for the work of breath light；Under the first state, the first LED element 22 is that light and shade alternately breathes effect
Fruit state, the second LED element 23 are in off state；Under second of state, the first LED element 22 is in off state, and only second
LED element 23 is open state, and the standby mode that the second LED element 23 is mainly television set is shown；The third state is
One LED element 22 and one second LED element 23 etc. are the state of unlatching.
Designing points of the present invention are, mainly to the improvement design of light guide plate, the light that LED element issues is from vertical portion
To tripping in light, go out light through transverse part, makes the light gradient entered in light guide plate, and then another brightness is transformed by a kind of luminance
Degree, generates submissive visual effect；
Followed by, it is in the gradually small design of the big both sides in center under forward sight state by light-emitting surface, the effect of light and shade gradual change is presented；
It furthermore is to pass through the design of LED element fixation hole, on the one hand, the installation of LED element is facilitated to position；On the other hand, make
LED element more multiple beam enters in light guide plate, and the light beam due to entering light guide plate increases, and derived light also increases, thus light
Effect gets a promotion；
And by atomization surface, the dispersion effect of the light entered in light guide plate is improved, so that realizing uniformly to go out in light-emitting surface
Light.
The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention,
Therefore any subtle modifications, equivalent variations and modifications to the above embodiments according to the technical essence of the invention, still
