Abstract
The invention discloses a light guide plate capable of inletting light from centre. The light guide plate comprises an acrylic substrate, lattice points are symmetrically arranged on the acrylic substrate along the central line, the lattice points close to the central line are small in density, and the lattice points far away from the central line are great in density; the density of the lattice points close to the central line is not less than 100,000/sq.m; the light can be introduced from the central line of the acrylic substrate so as to reduce the use number of the light-emitting diodes (LEDs), thereby reducing the cost.
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 middle part light inlet, center 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 middle part light inlet, center 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 center light inlet comprises the acrylic base material; Be symmetrically arranged with the site along its center line on the described acrylic base material, little near the dot density of center line; Dot density away from center line is large.
Preferably, to be no less than be 100000/square metre to the density of described site near center line.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
But on the light guide plate of center of the present invention light inlet, be symmetrically arranged with the site along its center line on the described acrylic base material, little near the dot density of center line; Dot density away from center line is large; It is 100000/square metre that the density of the site of close center line is no less than; Can adopt the center line light inlet from the acrylic base material during use, and then reduce the usage quantity of LED, thereby reduce cost.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
But accompanying drawing 1 is the schematic diagram of the light guide plate of center of the present invention light inlet;
Wherein: 1, acrylic base material; 2, center line; 3, site.
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 center of the present invention light inlet comprises acrylic base material 1; Be symmetrically arranged with site 3 along its center line 2 on the described acrylic base material 1, little near the dot density of center line 2; Dot density away from center line 2 is large; It is 100000/square metre that the density of the site 3 of described close center line 2 is no less than.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
But on the light guide plate of center of the present invention light inlet, be symmetrically arranged with the site along its center line on the described acrylic base material, little near the dot density of center line; Dot density away from center line is large; It is 100000/square metre that the density of the site of close center line is no less than; Can adopt the center line light inlet from the acrylic base material during use, and then reduce the usage quantity of LED, thereby 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.
Claims (2)
1. but the light guide plate of a center light inlet comprises the acrylic base material; It is characterized in that: be symmetrically arranged with the site along its center line on the described acrylic base material, little near the dot density of center line; Dot density away from center line is large.
2. but the light guide plate of described center light inlet according to claim 1 is characterized in that: it is 100000/square metre that the density of described site near center line is no less than.
