Abstract

The utility model discloses a light guide plate that has the figure, and including a light guide plate (1) and a leaded light point (2) of locating the light guide plate side, and the leaded light point on the light guide plate (2) part makes up various patterns of component and/or characters with part (3) of not setting up leaded light point. The utility model forms different pattern and characters through the leaded light point part that can give off light and the non- luminous component that does not set up leaded light point on the light guide plate. Not using the diffusion material just can solve the glare problem promptly, and the light can directly to jet out, the energy consumption reduces, improves the light efficiency, and lowers costs.

Description

The LGP that has figure

Technical field

The utility model relates to the light conduction device, relates in particular to a kind of practicality illumination and decorating lighting lamp, ornament, handicraft that is widely used in commercialization and family expenses, goes out the LGP of aspects such as guideboard, avigation light, advertising lamp box.

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.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.The site design of existing LGP all is that full version is layouted, dull no change, and profile also changes not quite.

Summary of the invention

Of the present utility model is for the site design that solves existing LGP all is that full version is layouted, dull no change, and profile also changes little technical problem, proposes a kind of LGP that has figure.

For solving the problems of the technologies described above, the LGP that has figure that the utility model proposes, it comprises LGP and is located at the leaded light point of this LGP one side.Leaded light point part on the LGP constitutes various patterns and/or literal with the part that leaded light point is not set.

The utility model adopts the site optical design in conjunction with artistic design, by various hollow out design, forms different pattern and literal on the LGP of different shape and different size.Being provided with leaded light point part is light-emitting zone, and openwork part is a non-luminous region.When importing various Different Light to LGP, after light is injected, form luminous pattern under the reflex by leaded light point, there is leaded light point part to derive light by light refraction, openwork part is that non-luminous region forms the dark space, thereby forms the LGP of pattern miscellaneous, literal.Compared with prior art, the utlity model has advantage:

(1) existing LGP must cooperate diffusion material could solve the problem of dazzle, the utility model can not use diffusion material and solves glare problem, and behind the cancellation diffusion material (also can cancel reflecting material), light can directly penetrate, can single, double luminous, enlarge lighting angle, energy consumption reduces, improve light efficiency, reduce cost;

(2) the utility model is used more extensive, not only can be used for illumination, also can be used for decorating, the art work etc., after light evenly soft (also can regulate local light and shade zone luminosity by the site design), light were injected, profile and pattern were vividly attractive in appearance, shape is ever-changing, energy-conserving and environment-protective.Can be widely used in commercialization and family expenses practicality illumination and decorating lighting lamp, ornament, handicraft, go out guideboard, avigation light, advertising lamp box etc.

The specific embodiment

See also Fig. 1 a, Fig. 1 b, the LGP that has figure that the utility model proposes, the leaded light point 2 that it comprises a polygon LGP 1, is located at the light source (not shown) of LGP side and is located at LGP one side.And the leaded light on the LGP is put 2 parts and is constituted various patterns and/or literal with the part 3 that leaded light point is not set.

Shown in Fig. 1 a, Fig. 1 b, first embodiment of the present utility model, wherein the leaded light on the LGP 1 is put the pattern of 2 parts and part 3 formations " standing on the bird on the branch " that leaded light point is not set.

Shown in Fig. 2 a, Fig. 2 b, second embodiment of the present utility model, wherein the leaded light on the LGP 1 is put the pattern of 2 parts and part 3 formations " cage " that leaded light point is not set.

Shown in Fig. 3 a, Fig. 3 b, the 3rd embodiment of the present utility model, wherein the leaded light on the LGP 1 is put the pattern of 2 parts and part 3 formations " Little Bear " that leaded light point is not set.

Shown in Fig. 4 a, Fig. 4 b, the 4th embodiment of the present utility model, wherein the leaded light on the LGP is put 2 parts and the part 3 formation literal that leaded light point is not set.

Certainly, as required, leaded light is put 2 parts can also constitute various patterns, literal with the part 3 that leaded light point is not set, as, form pattern by letter, the pattern that constitutes arbitrarily of Chinese character, pattern, letter is perhaps arranged, or the like.

LGP 1 of the present utility model can also be other shapes as required, as rectangular flat, circular flat board or the like.Also can constitute various three-dimensional shapes, shown in Fig. 5 a, Fig. 5 b, tabula rasa 1 constitutes a square column type, and the inside and outside lip-deep leaded light of square column type is put 2 parts and do not had the pattern of part 3 formations one " Little Bear " of leaded light point, and light source 4 is located at the two ends up and down of square column type LGP 1 respectively.Shown in Fig. 6 a, Fig. 6 b, tabula rasa 1 formation one is cylindrical, and cylindrical inside and outside lip-deep leaded light is put 2 parts and do not had the pattern of part 3 formations one " Little Bear " of leaded light point.

The utility model is on the LGP of different shape and different size, and the leaded light point part by can be luminous forms different patterns and literal with the non-luminous component that leaded light point is not set.Can not use diffusion material and solve glare problem, and make light directly to penetrate, energy consumption reduces, and improves light efficiency, reduces cost.The utility model is used more extensive, not only can be used for illumination, also can be used for decoration, handicraft etc.Light is evenly soft, profile is vividly attractive in appearance, shape is ever-changing, energy-conserving and environment-protective.
