Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " connection " should be done
It broadly understood, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can be directly connected,
It can also be indirectly connected through an intermediary.For the ordinary skill in the art, can be understood with concrete condition above-mentioned
The concrete meaning of term in the present invention.
In conjunction with shown in Fig. 1 to Fig. 3, a kind of side-edge type backlight provided in an embodiment of the present invention, including framed 2, light guide plate 1
And the light source positioned at 1 incidence surface side of light guide plate, framed 2 be a kind of adhesive frame structure, and outside is connect with the external world, is set for fixation
It sets, front side is equipped with limiting section, and framed 2 can be the two sides for existing only in the light guide plate adjacent with incidence surface, can also be to deposit
It is its excess-three side in addition to incidence surface, the limit extractd on direction is formed to light guide plate 1 by its limiting section to realize；
There is fluid flow passageway 11 with framed 2 tactile inside of the side edge of light guide plate 1, the fluid flow passageway 11 is for being passed through
The fluid that air etc. circulates.
When backlight works, light guide plate 1 generates heat after being irradiated, the heat transfer that light guide plate 1 is generated to
Framed 2 contacted, framed 2 transfer heat to the fluid in its fluid flow passageway 11 again, and fluid will be warm by flowing
Amount is taken away, and to realize the cooling to light guide plate 1, strengthens the heat dissipation of side-edge type backlight.
Wherein, framed 2 sides being in contact with light guide plate 1 are equipped with cambered surface bulge-structure 21, and light guide plate 1 connects with framed 2
Tactile side is equipped with cambered surface sunk structure 12, and framed 2 pass through cambered surface bulge-structure 21 and cambered surface sunk structure 12 with light guide plate 1
Coordinate and forms cambered surface contact connectio.The form of cambered surface connection increases the contact area between framed 2 and light guide plate 1, from
And opposite fitting intensity is improved, also improve heat exchange efficiency；Moreover, because a part of glue frame is overlapped with light guide plate 1, thus also
The design width of frame can be reduced.
It should be noted that realize said effect, the present invention is simultaneously not limited to above structure form, as long as by framed
2 are set as cambered surface contact connectio with light guide plate 1, such as can also be and arc is arranged in the side that light guide plate 1 is contacted with framed 2
Face bulge-structure 21 and the side setting cambered surface sunk structure 12 contacted with light guide plate 1 framed 2.It is above-mentioned to be arranged on framed 2
Cambered surface bulge-structure 21 is only preferred, because herein on basis, can also set fluid flow passageway 11 in section in circle
Shape or ellipse structure type, not only contribute to the machine-shaping to fluid flow passageway 11 in this way, but also can make with
The wall thickness of segment fluid flow circulation passage 11 that light guide plate 1 contacts more they tends to uniformly, especially in the inner wall of fluid flow passageway 11 and
In the case of the curvature of above-mentioned cambered surface bulge-structure 21 is identical, the part mould between fluid flow passageway 11 and light guide plate 1
The material thickness of frame 2 can accomplish absolute uniform in theory, and this part is just to play conductive force between light guide plate 1 and fluid
Part, therefore, can under the premise of ensureing it with enough support strengths, be made to it is thin as possible, to can either
Its heat transfer efficiency is improved, and the weak area of stress concentration will not be formed.
It is respectively provided with First Transition section 22 and the second transition between cambered surface sunk structure 12 and the front side and rear side of light guide plate 1
Section 23, that is to say, that cambered surface sunk structure 12 is not formed in the entire side of light guide plate 1, but in cambered surface sunk structure 12
All there are surpluses, respectively First Transition section 22 and the second changeover portion 23 for the exterior portion at both ends, that is, in light guide plate side
To, cambered surface sunk structure one end exterior portion all there are First Transition section, the cambered surface sunk structure other end it is outer
All there are the second changeover portions for side section；When the front side of the light guide plate is parallel with the framed front side, the First Transition
Section and the second changeover portion and it is described it is framed between all have interval, wherein the front side of the light guide plate goes out for the light guide plate
Light side；Relative torsion or opposite collision can occur between light guide plate 1 and framed 2 because of outer force effect, when the front side of light guide plate 1 with
When framed 2 front side is parallel, preferably it is disposed as that there is interval between First Transition section 22 and the second changeover portion 23 and framed 2,
As a result, when light guide plate 1 twists relative to framed 2, First Transition section 22 and the second changeover portion 23 are equal in rotation direction
With activity space, it can't be formed and be collided with framed 2 corresponding portion.
On the other hand, shock absorber part 3 is preferably provided on framed 2 and between First Transition section 22 and framed 2, therefore,
When light guide plate 1 or so shakes, shock absorber part 3 forms resilient support between framed 2 and light guide plate 1, can reduce 1 band of light guide plate
The surge come；And shock absorber part 3 is preferably the band-shaped silica gel being arranged along framed 2 length direction, it can be in the leaded light of whole side
Resilient support is all formed between plate 1 and framed 2.
In addition, on framed 2 and being located between framed 2 outside and fluid flow passageway 11 equipped with buffering gap, buffering
Gap is used to provide the space needed for outside flexible deformation for the part framed 2 where fluid flow passageway 11, when light guide plate 1 is pressed
When to framed 2, due to the presence of buffer gap 13, framed 2 be in contact with light guide plate 1 partially towards framed 2 fixed part
Direction occur elastic deformation can greatly alleviate the percussive pressure that light guide plate 1 is brought as a result, by this elastic deformation process
Power.Also, buffering gap preferably has opening, and is the whole structure in gradually wealthy formula from the inside to the outside, that is, by framed front side
To framed rear direction, the opening is in the structure of gradually wealthy formula.If section is trapezoidal structure, make the slow of different radial zones
The width and its radius of gyration for rushing gap 13 are adapted, and avoid the generation of touching.
The present invention also provides a kind of display equipment, which includes side-edge type backlight as described above.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
