Description

A kind of puzzle type LGP and preparation method thereof

Technical field

The present invention relates to the light conduction device, relate in particular to a kind of puzzle type LGP that is applicable to all kinds of illuminations, artistic lighting and decorative lighting, aspect such as backlight and preparation method thereof.

Background technology

The LGP design principle comes from the LCDs of notebook computer.LGP utilizes fluorescent lamp, CCFL, led light source to see through by leaded light point or leaded light groove after the optical principle calculating, under reflective membrane (reflecting plate) and diffusion barrier effect, changes line source or spot light into area source.For making the LGP can uniformly light-emitting, must be by various densitys, leaded light point not of uniform size, basic identical to guarantee light toward the efficient of all directions reflection.In the light reflected back LGP that the purposes of reflector plate (reflecting plate) is bottom surface of light guide plate is revealed out, be used for improving the service efficiency of light, improve brightness.Because LED is a kind of spot light, directly use the eyes that can stimulate the people, existing technology is to add diffuser plate, monoblock side as reflection, lens, direct-injection type and go into mode such as optical plane LGP and change spot light into area source by much different.The effect of diffusion barrier is to make light more even softer.Being of wide application of LGP is as TV backlight, illumination, decoration, advertisement, sign board or the like.Existing LGP is all made by whole block material, cuts the leftover pieces that get off and just can not well utilize, and causes the wasting of resources.In addition, the profile of LGP also changes not quite.

Summary of the invention

The present invention is to be made and can not well be utilized leftover pieces by whole block material in order to solve existing LGP, causes the technical problem of the wasting of resources, proposes a kind of puzzle type LGP that leftover pieces are made and preparation method thereof that utilizes.

For solving the problems of the technologies described above the puzzle type LGP that the present invention proposes, the leaded light point that it comprises LGP and is located at this LGP one side.This LGP is stitching into one by the light element of multiple shape.

Wherein, described light element can be any of rectangle, triangle, picture combination.

Described light element can be made by acrylic, glass, any optical material of PC.

Described light element can or corrode any method by printing, engraving, mould to be made.

Described light element can be bonded to one by glue, also can clamping is integral to transparent material by being located at front and back sides.

Described light element can constitute difform three-dimensional assembly.

The preparation method of the puzzle type LGP that the present invention proposes, its step is as follows:

Design required leaded light point earlier, make the leaded light point on the surface of corner LGP;

According to the design shape requirement, the corner LGP is cut into the light element of multiple shape again;

At last each light element is spliced into holistic LGP.

Compared with prior art, the present invention has advantage:

1, existing LGP all is a monoblock, can not well utilize leftover pieces, waste resource etc.And the present invention can well utilize the leftover pieces that vary in size (waste material) resource, and by the LGP that the polylith leftover pieces are formed, effect is fine, reduces the wasting of resources, improves stock utilization, reduces cost;

2, the present invention's application is more extensive, has the technology illuminating effect, and the life-span is long, energy-conserving and environment-protective.Product is widely used in fields such as all kinds of illuminations, decorative lighting, handicraft.

The specific embodiment

See also Fig. 1 a, Fig. 1 b, the puzzle type LGP that the present invention proposes comprises LGP 1 and the leaded light point 2 of being located at this LGP one side.LGP 1 is stitching into one by the light element 3 of multiple shape.Wherein, light element 3 can select for use different shape any, as, rectangle, triangle, picture combination etc.

Shown in Fig. 1 a, Fig. 1 b, the first embodiment of the present invention by the square light element 3 that has the big or small leaded light point 2 of difference of fritter, is spliced into the LGP 1 of one " grid " shape large square.Light source 4 is located at the side of LGP 1.

Shown in Fig. 2 a, Fig. 2 b, the second embodiment of the present invention by the picture combination light element 3 that has leaded light point 2 of fritter, is spliced into the LGP 1 of a circle anyhow.Light source 4 is located at the side of LGP 1.

Shown in Fig. 3 a, Fig. 3 b, the third embodiment of the present invention by the picture combination light element 3 that has leaded light point 2 of fritter, is spliced into the LGP 1 of square column type anyhow.And light source 4 is located at the upper end and/or the lower end of this square column type LGP 1.Can also be spliced into the LGP of other three-dimensional shape as required.

Each light element 3 among the described embodiment can be bonded to holistic LGP 1 with glue.

Shown in Fig. 4 a, Fig. 4 b, the fourth embodiment of the present invention by the square light element 3 that has the big or small leaded light point 2 of difference of fritter, is spliced into the LGP 1 of one " grid " shape large square.Light source 4 is located at the side of LGP 1.And each light element 3 is by transparent material clamping LGPs 1 in aggregates such as the clear glass 5 of being located at front and back sides or acrylics.

The preparation method of LGP of the present invention, its step following (see also Fig. 1 a):

Step 1: design required leaded light point earlier, at the leaded light point 2 of LGP surface, the corner making-difformity of collecting, different size and different densities distribution.Certainly, make the leaded light point again after can being spliced into LGP, effect can be not very good so yet, sometimes the part printing points phenomenon of biting.Leaded light point 2 can or corrode any method by printing, engraving, mould to be made.LGP is made by acrylic, glass, any optical material of PC.

Step 2: again according to the design shape requirement, the corner LGP that will have leaded light point cuts into the light element 3 of multiple shape, as, rectangle, triangle or spliced figure (shown in Fig. 2 b);

Step 3: at last each light element 3 is spliced into holistic LGP 1.

Wherein, each light element 3 can be bonded to holistic LGP 1 with glue.

As required, each light element 3 can be by transparent material clamping LGPs 1 in aggregates such as the clear glass 5 of being located at front and back sides or acrylics.See also Fig. 4 a, Fig. 4 b.

The corner material that utilization of the present invention varies in size carries out the making of leaded light point and cuts into the light element of different shape, then light element is spliced into the LGP of the different shape of energy leaded light.Mode by the side light inlet is injected light, and LGP transfers spot light or line source to area source, can also put the diffusion material on reflectance coating and surface etc. overleaf, and the present invention has changed the image of plane lamp, is applicable to all kinds of illuminations, ornament materials etc. fully.The puzzle type LGP can be that single face is luminous, double-side, also can be the puzzle type LGP of different shapes such as cylindricality.
