Refer to Fig. 1.Lighting of the present invention comprises dislocation light guide plate 1 and light source 2.Wherein:
Dislocation light guide plate 1 comprise 11He Yu bottom surface, bottom surface over against end face 12.On bottom surface 11, be provided with the first light guiding points 111, on end face 12, be provided with the second light guiding points 121, and described the first light guiding points is dislocatedly distributed at orthogonal projection and second light guiding points of end face.
The first light guiding points 111 and the second light guiding points 121 all can adopt the modes such as engraving, corrosion and printing to make.The first light guiding points 111 and the second light guiding points 121 form various luminous patterns, comprise any or Chinese character, the figure of Chinese character, letter or figure, the combination in any of letter.The first light guiding points 111 and the second light guiding points 121 can be any shapes, as round, yi word pattern, the shape such as cross and star-like.The first light guiding points 111 and the second light guiding points 121 that these difformities, different size or different densities distribute constitute various luminous patterns.
By the light guiding points of bottom surface of light guide plate and end face is shifted to install, thereby can better increase the density of light guiding points, the raising of density improves light efficiency, and make light guiding points formation thickness drop by pros and cons dislocation mode, light is easily through light guide plate, thereby brightness and uniformity coefficient have been improved, do not use diffusion material can solve glare problem completely yet, elimination does not have diffuser plate and the surperficial light guiding points burnt hair phenomenon brought, and after cancellation diffusion material, light can directly be penetrated by light guide plate, reduce energy consumption, improve light efficiency (luminous flux generally can improve more than 20%), reduce costs (reducing the material costs such as light source and diffusion).
Also can on the first light guiding points 111 and the second light guiding points 121, be printed with coloring material or self-luminescent material, form coloring material or self-luminescent material site, to build versicolor luminous pattern or not need light illumination and show various luminous patterns.
Light guide plate can be arranged to difformity as required, as tabular, right cylinder, polygon cylinder etc.
Embodiment mono-
Please also refer to Fig. 2 to Fig. 4.In this specific embodiment, dislocation light guide plate is a square plate, it comprise 31He Yu bottom surface, bottom surface over against end face 32.On bottom surface 31, be provided with the first light guiding points 311, on end face 22, be provided with the second light guiding points 321.The first light guiding points and the second light guiding points regular distribution, and described the first light guiding points 311 is dislocatedly distributed at orthogonal projection 312 and second light guiding points 321 of end face 32.
Embodiment bis-
Please also refer to Fig. 5 to Fig. 7.In this specific embodiment, dislocation light guide plate is similarly a circular slab, it comprise 41He Yu bottom surface, bottom surface over against end face 42.On bottom surface 41, be provided with the first light guiding points being formed by light guiding points 411 and light guiding points 412, on end face 42, be provided with the second light guiding points being formed by light guiding points 421 and light guiding points 422.Light guiding points 411 and light guiding points 412 are respectively 413 and 414 in the orthogonal projection of end face 42.Equally, the first light guiding points and the second light guiding points form luminous pattern jointly, and described the first light guiding points is dislocatedly distributed at orthogonal projection and second light guiding points of end face.
Embodiment bis-is only that from the difference of embodiment mono-luminous pattern of the first light guiding points and the second light guiding points formation is different.
The method for making of dislocation light guide plate of the present invention is as follows:
The light guiding points that first design the making needing early stage, carries out the design of the first light guiding points and the second light guiding points according to the requirement of light guide plate.The first light guiding points and the second light guiding points adopt respectively engraving and printing to make, and also need to carry out color separation processing, need engraving to separate and process with printing, then carry out web plate making.
And then first in the bottom surface of acrylic, make the first light guiding points as requested, at end face, make the second light guiding points, and described the first light guiding points is dislocatedly distributed at orthogonal projection and second light guiding points of end face.
Dislocation light guide plate of the present invention by arranging the first light guiding points on bottom surface, the second light guiding points is set on end face, and described the first light guiding points is dislocatedly distributed at orthogonal projection and second light guiding points of end face, by pros and cons dislocation mode, make light guiding points and form thickness drop, light easily passes light guide plate, thereby has improved brightness and uniformity coefficient.
The present invention shifts to install light guiding points and different site size production method by bottom surface and end face, generate all kinds of patterns, can in the light guide plate of various shapes (comprising three-dimensional shape) and different size, form different patterns and/or word, can design according to the shape of various different densities, light guiding points, different light-emitting zone requirements etc.In the time of the various Different Light of input (as the light source of multiple color), injecting under the light effect different with light guiding points, light guide plate surface can produce various luminous patterns, can be one side luminous, also can be double-side, it can be that silk-screen, laser engraving also can go out by burn into mould that light guiding points is made, and while using printing ink to manufacture light guiding points, also can add various coloring materials, self-luminescent material.In the time of input Different Light, whole light-emitting zone forms the luminous of different light and shades, thereby produce, has various solid and plane pattern.
Compared with prior art, this patent has the following advantages:
(1) existing light guide plate range of application is narrow, and in the not more variation of design aspect, light efficiency is also lower.The present invention can better increase light guiding points density, the raising of density improves light efficiency, the uniformity coefficient of light guide plate is also than being easier to control (uniformity coefficient of corresponding raising light guide plate), can not use diffusion material can solve glare problem completely yet yet, elimination does not have diffuser plate and the surperficial light guiding points burnt hair phenomenon brought, and after cancellation diffusion material, light can directly be penetrated by light guide plate, reduce energy consumption, improve light efficiency (luminous flux generally can improve more than 20%), reduce costs (reducing the material costs such as light source and diffusion);
(2) the present invention is in design aspect flexible Application more, uses more extensively, has value of art appreciation, not only can for illumination, also can be for ornament, handicraft etc.Its light evenly soft, profile vividly attractive in appearance, shape is ever-changing, stereoscopic sensation is stronger, extended light guide plate illuminating product line, energy-conserving and environment-protective.Can be widely used in all kinds of illuminations, artistic lighting, decorative lighting, handicraft, the artwork, furniture illumination, ornament materials, show window, cabinet, backlight, show stand, go out the fields such as guideboard, guide plate, advertising lamp box.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
