Abstract
The invention discloses a light guide plate with light incident bilateral sides. The light guide plate comprises acrylic base materials; network points are symmetrically formed on the acrylic base materials along a center line which is arranged between the upper lateral side and the lower lateral side of the acrylic base materials; the density of network points close to the upper lateral side of the acrylic base materials is small and the density of network points far away from the upper lateral side of the acrylic base materials is large; and the density of network points close to the lower lateral side of the acrylic base materials is small and the density of network points far away from the lower lateral side of the acrylic base materials is large. According to the light guide plate with the light incident bilateral sides, the network points are symmetrically formed on the acrylic base materials along the center line which is arranged between the upper lateral side and the lower lateral side of the acrylic base materials; the density of the network points close to the upper lateral side of the acrylic base materials is small and the density of the network points far away from the upper lateral side of the acrylic base materials is large; the density of the network points close to the lower lateral side of the acrylic base materials is small and the density of the network points far away from the lower lateral side of the acrylic base materials is large; and light can be simultaneously incident from the upper lateral side and the lower lateral side of the acrylic base materials during usage to reduce the using number of LEDs (Light Emitting Diodes) and accordingly the costs are reduced.
Description
Technical field
The present invention relates to a kind of improvement of light guide plate, but particularly a kind of can be from the light guide plate of the lower side of acrylic base material and lower side light inlet, both sides light inlet that cost is low.
Background technology
The light guide plate design concept comes from the LCDs of notebook computer, is the high-tech product that line source is changed into area source.Be base material with optical grade acryl (PMMA)/PC, use the back light model setting technology of LCD display and notebook computer, see through the high light line conductivity of site (light guiding points), through computer site (light guiding points) calculated, make the light guide plate light refraction become the equal light state of area source to make moulding.Product adopts spectrophotometry to combine with digital UV printing technology and is made under constant temperature, constant humidity, dustless environmental baseline, have that ultra-thin, superbright, leaded light are even, energy-saving and environmental protection, no dark space, durable, be difficult for the advantages such as yellow, installation and maintenance simple and fast; Common light guide plate is used long limit single-sided illumination, and such light guide plate need to be used more LED, thereby cost is higher.
Summary of the invention
But the present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of can be from the light guide plate of the lower side of acrylic base material and lower side light inlet, both sides light inlet that cost is low.
For achieving the above object, the technical solution used in the present invention is: but the light guide plate of a kind of both sides light inlet comprises the acrylic base material; Be provided with symmetrically the site along the center line between its upper side edge and the lower side on the described acrylic base material, the dot density of described upper side edge near the acrylic base material is little, and is large away from the dot density of the upper side edge of acrylic base material; The dot density of described lower side near the acrylic base material is little, and is large away from the dot density of the lower side of acrylic base material.
Preferably, to be no less than be 100000/square metre to the density of the site of described upper side edge near the acrylic base material.
Preferably, to be no less than be 100000/square metre to the density of the site of described lower side near the acrylic base material.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
But the light guide plate of both sides of the present invention light inlet, be provided with symmetrically the site along the center line between its upper side edge and the lower side on the described acrylic base material, the dot density of described upper side edge near the acrylic base material is little, and is large away from the dot density of the upper side edge of acrylic base material; The dot density of described lower side near the acrylic base material is little, and is large away from the dot density of the lower side of acrylic base material; Can be from the upper side edge of acrylic base material and lower side light inlet simultaneously during use, and then reduced the usage quantity of LED, thus reduce cost.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Wherein: 1, acrylic base material; 2, site; 3, lower side; 4, upper side edge; 5, center line.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, but the light guide plate of a kind of both sides of the present invention light inlet comprises acrylic base material 1; Be provided with symmetrically site 2 along the center line between its upper side edge 3 and the lower side 4 on the described acrylic base material 1, the dot density of described upper side edge 4 near acrylic base material 1 is little, and is large away from the dot density of the upper side edge 3 of acrylic base material 1; The dot density of described lower side 3 near acrylic base material 1 is little, and is large away from the dot density of the lower side 3 of acrylic base material 1; It is 100000/square metre that the density of the site of the upper side edge 4 of described close acrylic base material 1 is no less than; It is 100000/square metre that the density of the site of the lower side 3 of described close acrylic base material 1 is no less than.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
But the light guide plate of both sides of the present invention light inlet, be provided with symmetrically the site along the center line between its upper side edge and the lower side on the described acrylic base material, the dot density of described upper side edge near the acrylic base material is little, and is large away from the dot density of the upper side edge of acrylic base material; The dot density of described lower side near the acrylic base material is little, and is large away from the dot density of the lower side of acrylic base material; Can be from the upper side edge of acrylic base material and lower side light inlet simultaneously during use, and then reduced the usage quantity of LED, thus reduce cost.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
