Abstract
The invention discloses a light guide plate which comprises a base material, wherein lattice point clusters are arranged on the base material; lattice points close to a light source are small; lattice points away from the light source are large; the spacing between adjacent lattice points close to the light source is large; the spacing between adjacent lattice points away from the light source is small; the lattice points close to the light source have the density about 150,000 to 200,000 points per square meter; and the lattice points away from the light source have the density about 200,000 to 250,000 points per square meter. According to the light guide plate, the lattice points close to the light source are small and sparse, and the lattice points away from the light source are large and dense; and moreover, because large and dense lattice points have high brightness, and small and sparse lattice points have low brightness, short-side single-side light incidence can be adopted, and the using number of light-emitting diodes (LED) is reduced; and therefore, the cost is reduced.
Description
Technical field
the present invention relates to a kind of LGP, and particularly a kind of LGP from the one-sided light inlet of minor face that reduces the LED use amount, reduces cost belongs to the component technology field of filming apparatus.
Background technology
LGP design concept comes from the LCDs of notebook computer, is the high-tech product that line source is changed into area source.With optical grade acryl (PMMA)/PC is base material; The back light model setting technology of utilization LCD display and notebook computer; See through the high light line conductivity of site (leaded light point), site (leaded light point) calculated, make the LGP light refraction become the equal light state of area source to make moulding through computer.Product adopts spectrophotometry to combine with digital UV printing technology and under constant temperature, constant humidity, dustless environmental baseline, is made, have that ultra-thin, superbright, leaded light are even, energy-saving and environmental protection, no dark space, durable, be difficult for advantages such as yellow, installation and maintenance simple and fast; Common LGP uses the one-sided light inlet in long limit, and such LGP need use more LED, thereby cost is higher.
Summary of the invention
the present invention seeks to for the deficiency that overcomes prior art a kind of LGP from the one-sided light inlet of minor face that reduces the LED use amount, reduces cost to be provided.
for achieving the above object, the technical scheme that the present invention adopts is: a kind of LGP comprises base material; Said base material is provided with the site crowd, and is little near the site at light source place; Big away from site, light source place.
are preferred, and the interval of said adjacent site near the light source place is big; The interval of said adjacent site away from the light source place is little.
are preferred, are about 150000 to 200000/square metre near the density of site, light source place; Density away from site, light source place is about 200000 to 250000/square metre.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
On
LGP of the present invention, little and sparse near the site at light source place, big and intensive away from the site at light source place; Because big more intensive more site, its briliancy is high more, and more little sparse more site, its briliancy is low more, therefore can adopt the one-sided light inlet of minor face, and then has reduced the usage quantity of LED, thereby reduces cost.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 2 is that the site of LGP of the present invention is at the distribution plan near the light source place;
Accompanying drawing 3 is that the site of LGP of the present invention is at the distribution plan away from the light source place;
wherein: 1, site; 2, cold-cathode tube; 3, acrylic; 4, diffusion sheet; 5, prismatic lens; 6, reflector plate.
Embodiment
are done further detailed description below in conjunction with accompanying drawing and specific embodiment to the present invention.
like accompanying drawing 2, shown in 3, LGP of the present invention comprises base material; Said base material is provided with the site crowd, and is little near the site 1 at light source place; Big away from site 1, light source place; Said base material is an acrylic 3.The interval of said adjacent site 1 near the light source place is big; The interval of said adjacent site 1 away from the light source place is little; Said density near site, light source place 1 is about 150000/square metre; Said density away from site, light source place 1 is about 200000/square metre.
are as shown in Figure 1, and the application example of LGP of the present invention comprises cold-cathode tube 2, acrylic 3, diffusion sheet 4, prismatic lens 5, reflector plate 6, and said cold-cathode tube 2 is arranged on the minor face place of acrylic 3; Said diffusion sheet 4 is arranged on the top of acrylic 3; Said prismatic lens 5 is arranged on the top of diffusion sheet 4; Said reflector plate 6 is arranged on the below of acrylic 3; The lower surface of said acrylic 3 is printed with the site crowd; Less near the site 1 at said cold-cathode tube 2 places, and comparatively sparse, and density is about 150000/square metre; Bigger away from the site 1 at said cold-cathode tube 2 places, and comparatively intensive, and density is about 200000/square metre.
are as shown in Figure 1, and when cold-cathode tube 2 was luminous, light got in the acrylic 3, and a part of light passes the upper surface of acrylic 3 and produces refracted rays and spread out of through diffusion sheet 4, prismatic lens 5; Another part light produces reflection ray by the site 1 or the reflector plate 6 of acrylic 3 lower surfaces, and the upper surface from acrylic 3 spreads out of again.
On
LGP of the present invention, little and sparse near the site at light source place, big and intensive away from the site at light source place; Because big more intensive more site, its briliancy is high more, and more little sparse more site, its briliancy is low more, therefore can adopt the one-sided light inlet of minor face, and then has reduced the usage quantity of LED, thereby reduces cost.
More than
only is concrete exemplary applications of the present invention, and 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.
