Embodiment
See also Fig. 1.Lighting of the present invention comprises dislocation LGP 1 and light source 2.Wherein:
The dislocation LGP 1 comprise bottom surface 11 and with the bottom surface over against end face 12.Bottom surface 11 is provided with the first leaded light point 111, and end face 12 is provided with the second leaded light point 121, and the said first leaded light point is dislocatedly distributed at the orthogonal projection and second leaded light point of end face.
The first leaded light point 111 and the second leaded light point 121 all can adopt modes such as engraving, corrosion and printing to make.The first leaded light point 111 and the second leaded light point 121 constitute various luminous patterns, comprise any or Chinese character, the figure of Chinese character, letter or figure, the combination in any of letter.The first leaded light point 111 and the second leaded light point 121 can be Any shape, like round, yi word pattern, shape such as cross and star-like.The first leaded light point 111 and the second leaded light point 121 that these difformities, different size or different densities distribute constitute various luminous patterns.
Leaded light point through with bottom surface of light guide plate and end face shifts to install, thereby can better increase the density of leaded light point, and the raising of density improves light efficiency; And make leaded light point with pros and cons dislocation mode and constitute the thickness drop, light passes LGP easily, thereby has improved brightness and uniformity coefficient; Do not use diffusion material can solve glare problem fully yet, eliminate the surperficial leaded light point burnt hair phenomenon that does not have diffuser plate and bring, and behind the cancellation diffusion material; Light can directly be penetrated by LGP; Reduce energy consumption, improve light efficiency (luminous flux generally can improve more than 20%), (reducing material costs such as light source and diffusion) reduces cost.
Also can on the first leaded light point 111 and the second leaded light point 121, be printed with coloring material or self-luminescent material, form coloring material or self-luminescent material site, to make up versicolor luminous pattern or not need light illumination and show various luminous patterns.
LGP can be arranged to difformity as required, like tabular, right cylinder, polygon cylinder etc.
Embodiment one
Please in the lump referring to Fig. 2 to Fig. 4.In this specific embodiment, the dislocation LGP be a square plate, it comprise bottom surface 31 and with the bottom surface over against end face 32.Bottom surface 31 is provided with the first leaded light point 311, and end face 22 is provided with the second leaded light point 321.The first leaded light point and the second leaded light point regular distribution, and the said first leaded light point 311 is dislocatedly distributed at the orthogonal projection 312 and the second leaded light point 321 of end face 32.
Embodiment two
Please in the lump referring to Fig. 5 to Fig. 7.In this specific embodiment, the dislocation LGP be similarly a circular slab, it comprise bottom surface 41 and with the bottom surface over against end face 42.Bottom surface 41 is provided with first leaded light point that is made up of leaded light point 411 and leaded light point 412, and end face 42 is provided with second leaded light point that is made up of leaded light point 421 and leaded light point 422.Leaded light point 411 is respectively 413 and 414 with leaded light point 412 in the orthogonal projection of end face 42.Equally, the first leaded light point and the second leaded light point are common to constitute luminous pattern, and the said first leaded light point is dislocatedly distributed at the orthogonal projection and second leaded light point of end face.
Embodiment two only is that with the difference of embodiment one luminous pattern of the first leaded light point and second leaded light point formation is different.
The misplace method for making of LGP of the present invention is following:
The leaded light point that design the making that needs early stage earlier carries out the design of the first leaded light point and the second leaded light point according to the requirement of LGP.The first leaded light point and the second leaded light point adopt engraving and printing to make respectively, then also need carry out color separation processing, promptly need separate with printing engraving and handle, and carry out web plate then and make.
And then make first leaded light point in the bottom surface of acrylic earlier as requested, make second leaded light point at end face, and said first leaded light point is dislocatedly distributed at the orthogonal projection and second leaded light point of end face.
The present invention misplaces LGP through first leaded light point is set on the bottom surface; Second leaded light point is set on end face; And the said first leaded light point is dislocatedly distributed at the orthogonal projection and second leaded light point of end face; Make leaded light point with pros and cons dislocation mode and constitute the thickness drop, light passes LGP easily, thereby has improved brightness and uniformity coefficient.
The present invention shifts to install leaded light point and different site size production method through bottom surface and end face; Generate all kinds of patterns; Can on the LGP of different shape (comprising three-dimensional shape) and different size, form different pattern and/or literal, can design according to the shape of various different densities, leaded light point, different light-emitting zone requirements etc.In the time of the various Different Light of input (like the light source of multiple color); Injecting under the light effect different with leaded light point; The LGP surface can produce various luminous patterns; Can be single face luminous, also can be double-side, it can be that silk-screen, laser engraving also can go out by the burn into mould that leaded light point is made, and also can add various coloring materials, self-luminescent material when using printing ink to manufacture leaded light point.In the time of the input Different Light, whole light-emitting zone forms the luminous of different light and shades, has various solid and plane pattern thereby produce.
Compared with prior art, this patent has the following advantages:
(1) existing LGP 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 the leaded light dot density; The raising of density improves light efficiency, and the uniformity coefficient of LGP than being easier to control (uniformity coefficient of corresponding raising LGP), can not use diffusion material can solve glare problem fully yet yet yet; Elimination does not have diffuser plate and the surperficial leaded light point burnt hair phenomenon brought; And behind the cancellation diffusion material, light can directly be penetrated by LGP, reduces energy consumption; Improve light efficiency (luminous flux generally can improve more than 20%), (reducing material costs such as light source and diffusion) reduces cost;
(2) the present invention is in design aspect flexible Application more, uses more extensively, has value of art appreciation, not only can be used for illumination, also can be used for ornament, handicraft etc.Its light is evenly soft, profile is vividly attractive in appearance, shape is ever-changing, stereoscopic sensation is stronger, prolonged LGP 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 fields such as guideboard, guide plate, advertising lamp box.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
