Embodiment
The utility model provides a kind of light guide plate, to make the purpose of this utility model, technical scheme and effect more
It is clear, clear and definite, the utility model is further described below.It should be appreciated that specific embodiment described herein is only
To explain the utility model, it is not used to limit the utility model.
With reference to shown in Fig. 2 and Fig. 3, a kind of light guide plate, wherein, including an incidence surface 101, positioned at the incidence surface 101
One exiting surface 103 of adjacent side and the bottom surface 102 for being arranged at the back side of exiting surface 103, the lower end of incidence surface 101 are provided with light source
1, the first reticulate pattern 1023 is provided with bottom surface 102, and the lower end of the first reticulate pattern 1023 is provided with arc reticulate pattern 1021, arc reticulate pattern 1021
The curved arrangement centered on the light source 1 of the lower end of incidence surface 101, is provided between the reticulate pattern 1023 of arc reticulate pattern 1021 and first
Two reticulate patterns 1022, for connecting the reticulate pattern 1023 of arc reticulate pattern 1021 and first.Due to light conducting plate structure limitation and cost requirement
It is low, so general in the case where meeting the situation of properties of product requirement can all reduce quantity of light source, but between light source and light source because away from
From increase the light emitting anger of light source can be caused to intersect or overlap so that the luminous intensity at this reduces and uniformity of luminance drop
Low, now, according to common light guide plate, light source will diminish in the lighting angle entered in light guide plate, so as to cause luminous intensity
Weaken, therefore, the utility model is by setting up arc reticulate pattern 1021 in the lower end of bottom surface and being connected to arc reticulate pattern 1021 and the
The second reticulate pattern 1022 between one reticulate pattern 1023, make light emitting anger increase of the light source 1 in light guide plate, and then make the light extraction of light guide plate
Efficiency can reduce the usage quantity of light source 1 up to optimization, also can be suitably used for the frame of narrower backlight module, simultaneously
Avoid producing the technical problem of hot spot.
In practical application, arc reticulate pattern 1021 sets at least to one, and each arc reticulate pattern 1021 is in equidistant or Unequal distance row
Row.The effect of arc reticulate pattern 1021 is will to change the round that light enters after light guide plate, effectively dark between elimination light source 1
Area, the lighting angle that increasing light enters behind luminous zone；
It was verified that arc reticulate pattern 1021 can optimize the light emission rate of light guide plate, it is preferable that each in the present embodiment
Arc reticulate pattern 1021 is in equidistant arrangement.In practical application, light source 1 at least provided with one, arrange by the equidistant or Unequal distance that each light source 1 is in
Row.Preferably, each light source 1 is in equidistant arrangement in the present embodiment.
Further, the first reticulate pattern 1023 is regular reticulate pattern.Going out for light guide plate can be made by being arranged to the reticulate pattern of rule herein
Light rate is optimal effect.
Further, the second reticulate pattern 1022 is irregular reticulate pattern.Irregular reticulate pattern is set to make light guide plate herein
Luminenscence homogenization.
In practical application, light source 1 is LED.Light source 1 is preferably set to the LED of energy-conserving and environment-protective.
Referring to Fig. 1, existing light guide plate includes an incidence surface 101, the exiting surface 103 positioned at the 101 adjacent side of incidence surface
And a bottom surface 102 at the back side of exiting surface 103 is arranged at, the lower end of incidence surface 101 is provided with light source 1, rule is provided with bottom surface
The first reticulate pattern 1023 then.The light utilization efficiency of such light guide plate is too low, and the light sent is uneven, is reduced in the quantity of lamp source 1
In the case of, light guide plate light emission rate is relatively low, does not have preferable light-out effect, can only change the species, size or number of light source 1
Amount, causes to considerably increase production application cost.
A kind of light guide plate provided by the utility model, has the advantage that：1st, it is strong to improve the light that backlight is sent
Degree and uniformity, improve the luminous uniformity of light guide plate；2nd, product power consumption and product cost are reduced；It is 3rd, simple in construction,
Requirement to light source is low.
It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model
The protection domain that profit requires.
