Abstract
The utility model discloses a light guiding plate allowing side light inlet. The light guiding plate includes an acrylic base material, wherein screen dots are arranged on the acrylic base material in a symmetrical manner along the center line between an upper side edge of the acrylic base material and a lower side edge of the acrylic base material, the density of the screen dots which are close to the upper side edge of the acrylic base material is low, the density of the screen dots which are far away from the upper side edge of the acrylic base material is high, the density of the screen dots which are close to the low side edge of the acrylic base material is low, and the density of the screen dots which are far away from the lower side edge of the acrylic base material is high. In the light guiding plate, screen dots are arranged on the acrylic base material in a symmetrical manner along the center line between an upper side edge of the acrylic base material and a lower side edge of the acrylic base material, the density of the screen dots which are close to the upper side edge of the acrylic base material is low, the density of the screen dots which are far away from the upper side edge of the acrylic base material is high, the density of the screen dots which are close to the low side edge of the acrylic base material is low, and the density of the screen dots which are far away from the lower side edge of the acrylic base material is high. The light guiding plate is used in such a way that light goes in from the upper side edge of the acrylic base material and the lower side edge of the acrylic base material at the same time, so that the number of the light emitting diode LED used is decreased, and cost is reduced.
Description
Technical field
the utility model relates to a kind of improvement of light guide plate, particularly a kind of can from the lower side of acrylic base material and lower side light inlet, cost low can both sides light inlet light guide plate.
Background technology
light guide plate design concept comes from the LCDs of notebook computer, is line source to be changed into the high-tech product of area source.With optical grade acryl (PMMA)/PC, it is base material, 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 light guide plate light refraction become the equal light state of area source to manufacture 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.
Utility model content
the utility model object be in order to overcome the deficiencies in the prior art, provide a kind of can from the lower side of acrylic base material and lower side light inlet, cost low can both sides light inlet light guide plate.
for achieving the above object, the technical solution adopted in the utility model is: a kind of light guide plate that can both sides light inlet, comprises acrylic base material; On described acrylic base material, along the center line between its upper side edge and lower side, be provided with symmetrically site, the dot density of the described upper side edge near acrylic base material is little, large away from the dot density of the upper side edge of acrylic base material; The dot density of the described lower side near acrylic base material is little, 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 the described upper side edge near acrylic base material.
preferably, to be no less than be 100000/square metre to the density of the site of the described lower side near acrylic base material.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
light guide plate that can both sides light inlet described in the utility model, on described acrylic base material, along the center line between its upper side edge and lower side, be provided with symmetrically site, the dot density of the described upper side edge near acrylic base material is little, large away from the dot density of the upper side edge of acrylic base material; The dot density of the described lower side near acrylic base material is little, 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 costs.
Accompanying drawing explanation
below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
the propagation path of light schematic diagram that accompanying drawing 1 is light guide plate of the present utility model;
wherein: 1, acrylic base material; 2, site; 3, lower side; 4, upper side edge; 5, center line.
embodiment
below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
as shown in Figure 1, a kind of light guide plate that can both sides light inlet described in the utility model, comprises acrylic base material 1; On described acrylic base material 1, along the center line between its upper side edge 3 and lower side 4, be provided with symmetrically site 2, the dot density of the described upper side edge 4 near acrylic base material 1 is little, large away from the dot density of the upper side edge 3 of acrylic base material 1; The dot density of the described lower side 3 near acrylic base material 1 is little, 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 described upper side edge 4 near acrylic base material 1 is no less than; It is 100000/square metre that the density of the site of the described lower side 3 near acrylic base material 1 is no less than.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
light guide plate that can both sides light inlet described in the utility model, on described acrylic base material, along the center line between its upper side edge and lower side, be provided with symmetrically site, the dot density of the described upper side edge near acrylic base material is little, large away from the dot density of the upper side edge of acrylic base material; The dot density of the described lower side near acrylic base material is little, 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 costs.
below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
