Penetrate and respectively obtain reflection light 2 and refracted light 3, refracted light 3 is reflected through the second inclined-plane 222 and refraction respectively obtains reflected light
Line 5 and refracted light 4, reflector plate 40 reflection of the refracted light 4 through being located at the outside of bottom surface 20 obtain reflection light 6, reflection light 6
Into the first inclined-plane 221, through the first secondary reflection and refraction again, so by the reflection on the first inclined-plane 221 and the second inclined-plane 222,
Refraction circulation, so that the utilization rate of light is maximum.In other embodiments, cell wall can also be arc surface, pass through circular arc for circulation
The cell wall in face is reflected and reflected to incident light.
Further, Fig. 4 is refer to, the inclination angle a of the first inclined-plane 221 is less than the inclination angle b of the second inclined-plane 222.The present embodiment
Middle that the inclination angle a of first inclined-plane 221 is set smaller than into the inclination angle b of the second inclined-plane 222, it can be seen from geometry relation, angle is got over
Its opposite side is elongated longer greatly.The inclination angle a of the first inclined-plane 221 opposite side is the projection side on the second inclined-plane 222 in the present embodiment, the
The inclination angle b of two inclined-plane 222 opposite side is the projection side on the first inclined-plane 221, so that the projection side on the first inclined-plane 221 is oblique more than second
The projection side in face 222, can increase the light entered from the first inclined-plane 221, a large amount of light entered by the first inclined-plane 221,
Under the reflection on the first inclined-plane 221 and the second inclined-plane 222, refraction, making the amount of light of exiting surface 10 increases, so as to improve light
Utilization rate.In another embodiment, the first inclined-plane 221 of the first V-groove of each in light guide plate 22 can be arranged to mutually flat
OK, and the second inclined-plane 222 is arranged to mutually balance each other, so that there is relation parallel to each other between each first V-groove 22, side
Just to the processing of the first V-groove 22.
Further, the light conducting plate body 100 includes incidence surface 30, the first V-groove 22 to the incidence surface 30
Distance is M, and the inclination angle a of the first inclined-plane 221 of the first V-groove 22 angle is directly proportional to M.Understandably, light guide plate is real
The conduction of existing light, must have the entrance passage of light, the entrance passage of this light is incidence surface 30.Will be with the present invention
The vertical side of exiting surface 10 and bottom surface 20 is set as incidence surface 30, and light enters from incidence surface 30, by bottom surface of light guide plate
20 reflection, refraction etc. processing, gone out from exiting surface 10, realize that light, to the conduction of exiting surface 10, changes from side incident face 30
The propagation path of light is become.Because of the first V-groove 22 parallel arranged on bottom surface 20, so that the first V-groove 22 and incidence surface 30
In parallel position.The distance between first V-groove 22 and incidence surface 30 are defined as M, because the first V-groove 22 has multiple,
And parallel arranged, so each first V-groove 22 is differed to the distance between incidence surface 30 M.The meeting in communication process because of light
There is decay, so that the incident ray that first V-groove 22 more remote apart from incidence surface 30 is received is weaker, this part is made accordingly
The light guide of exiting surface 10 is also weaker, and then makes the light extraction of light guide plate uneven.In order to avoid the generation of this problem, this implementation
Example sets the inclination angle a of the first inclined-plane 221 angular dimension according to the distance apart from M of the first V-groove 22 and incidence surface 30, when
The distance of first V-groove 22 and incidence surface 30 is more remote, i.e. M values are bigger, by getting over that the inclination angle a of the first inclined-plane 221 angle is set
Greatly, the first inclined-plane 221 is made more fully to be reflected, refraction is handled, and exiting surface 10 is obtained more light；When the first V-type
The distance of groove 22 and incidence surface 30 is nearer, i.e. M values are smaller, by the inclination angle a of the first inclined-plane 221 angle set it is smaller, make the
The less progress in one inclined-plane 221 is reflected, refraction processing, reduces the light guide of exiting surface 10.I.e. by by the first V-groove 22
The inclination angle a of first inclined-plane 221 angle is arranged to the mode being directly proportional to M, realizes the uniform in light emission of light guide plate.
Alternatively, the spacing distance N and M between two adjacent first V-grooves 22 is inversely proportional.Two adjacent first V
Spacing distance N between type groove 22 characterizes the density degree of the first V-groove 22, when spacing distance N is bigger, the first V-shape ditch
The first V-groove 22 in slot structure 21 is thinner, on the contrary then closeer.When the first V-groove 22 is thinner, its reflection to light, folding
The number of processes penetrated will be lacked, more close reflection then to light, refraction number of processes will be more.So as to when first
V-groove 22 to the incidence surface 30 apart from M it is bigger when, the spacing distance N between two adjacent first V-grooves 22 is set
It is smaller, the first V-groove 22 is arranged closely, increase the reflection and refraction to light, improve the light guide of exiting surface 10；When
One V-groove 22 gets over hour to the incidence surface 30 apart from M, and the spacing distance N between two adjacent first V-grooves 22 is set
It is bigger, the first V-groove 22 is arranged sparse, reduce reflection and refraction to light, reduce the light guide of exiting surface 10.I.e.
By way of being arranged to be inversely proportional with M by the spacing distance N between adjacent first V-groove 22, realize that the light extraction of light guide plate is equal
It is even.
Further, it is provided with the second V-shape groove structure on the exiting surface 10.
Incident ray changes light in reflection, the refraction of the first V-groove 22 by the V-shape groove structure 21 of bottom surface 20 first
, it is necessary to be blazed abroad by exiting surface 10 after the propagation path of line.The present embodiment improves light extraction to further gather light
Brightness, is provided with the second V-shape groove structure, and this second V-shape groove structure on exiting surface 10 including multiple parallel
Second V-groove of arrangement, further to locate to the light that processing is reflected, reflected by the V-shape groove structure 21 of bottom surface 20 first
Reason, lifts the brightness of light guide.Alternatively, circular arc mistake is passed through between the two neighboring V-groove of first V-groove 22 and/or second
Degree connection, so that seamlessly transitting between realizing the adjacent V-groove of first V-groove 22 and/or second.
