Description

A kind of Even light lamp box

Technical field:

The utility model relates to the lamp box of a kind of advertising, indication or decorative use, specifically belongs to the Even light lamp box of Advertisement label.

Background technology:

In the prior art, advertising lamp box generally all by casing, be arranged at the light source in the casing and be affixed on the form surface, the advertisement picture that is used to show forms, big this type of advertising lamp box of casing thickness shows that not only area is less, and owing to be provided with a plurality of light sources and making that the lamp box overall volume is bigger in the casing, structure is also comparatively heavy.The advertising lamp box of the automatic conversion picture of a kind of form is disclosed as the Chinese patent CN2405284 that announced on November 8th, 2000, this lamp box comprises a housing of being made up of upper cover plate, lower cover and biside plate, painted scroll and the rotation axis of broadcasting picture are installed in the housing, the front of housing is equipped with transparent window, the inboard of transparent window is provided with a dianegative parallel with the shape form, between dianegative and the transparent window picture is installed, roll up on painted scroll at the two ends of picture, also is provided with the motor rotation control system in the housing.Its complex structure of this advertising lamp box, cost are higher, and also comparatively inconvenience is installed.

The utility model content:

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of not only simple in structure, with low cost, easy for installation, and illumination effect is very evenly saved the featheredge Even light lamp box of spacial flex more.

The purpose of this utility model is achieved by the following scheme: the Even light lamp box that provides according to the utility model, form by framework, lamp source, reflective membrane, even light film, panel, picture, described Even light lamp box, the top of light source or upper and lower all are respectively equipped with an even light film, and described even light film is provided with one group of optical waveguide layer.

The Even light lamp box that provides according to the utility model also has following attached technical characterictic:

Include a transparent plastic film (or thin slice) in the even light film of described one deck, silk-screen has the site of some leaded lights on the described transparent plastic film, described leaded light site all is to press the optical refraction principle by the leaded light that varies in size to come arranged distribution, be imprinted on then on the transparent plastic film, form one deck optical waveguide layer.

The top or the upper and lower of the even light film of described one deck all are respectively equipped with a light penetrating panel, but described panel is provided with the picture silk-screen or is pasted with the advertisement picture.

Described lamphouse light source is a fluorescent tube, fluorescent tube on same level height equably and be listed in the lamp box inside casing.

The inner peripheral wall of described lamp box is provided with reflective membrane, with light energy reflected to panel.

The Even light lamp box that provides according to the utility model has following advantage compared to existing technology: owing to adopted the technology of even mating plate, make the thickness of lamp box fall minimizing greatly, eliminated because lamp box is done thinly, the distance of fluorescent tube and panel seldom produces the phenomenon of fluorescent tube shadow, makes the non-uniform light of lamp box.

Description of drawings:

The embodiment that provides below in conjunction with accompanying drawing is elaborated to the utility model;

Fig. 1 is the structural drawing of a kind of embodiment of the utility model Even light lamp box, and for clearly showing its inner structure, this figure is the cross-sectional view of lamp box;

Fig. 2 is the optical principle synoptic diagram that there is shown this embodiment;

Fig. 3 be should embodiment in the synoptic diagram of light guide;

Fig. 4 is the not other optical schematic diagram of a kind of this embodiment;

Embodiment:

Referring to Fig. 1, as the structural drawing of a kind of embodiment of the present utility model, for clearly showing its inner structure, this figure is that the xsect of lamp box cuts view, there is shown the cross-sectional structure of the lamp box of this embodiment.Form by framework 1, lamp source 2, even light film 4, panel 5, picture 6, base plate 7 in the Even light lamp box that provides according to the utility model; Lamp box shown in the figure by cover piece 11 on one and following cover piece 12 with combine; Be provided with light source 2 in lamp box, light source is evenly distributed in the casing on same horizontal line; Periphery in lamp box all is respectively equipped with reflective membrane 3, reflective membrane 3 with most light energy reflected of lamp source to panel 5; Be provided with an even light film 4 above lamp source, described even light film 4 propagates into the light of light source fluorescent tube 2 on the panel 5 effectively equably, from making that to obtain uniform luminous effect exhibition picture 6 is effectively showed.

Referring to Fig. 2: the issued light of light source shown in figure line is through the variation journey condition after the even light film 4.

Described light source 2 is a fluorescent tube, the light that described fluorescent tube sends is a pointolite, so it is bright especially that the light that obtains on the panel of lamp box can occur near the place of fluorescent tube, the phenomenon that the fluorescent tube shadow occurs, making what obtain on panel is uneven illumination effect, in order to eliminate this phenomenon, the utility model has been set up an even light film 4 above light source 2, as shown in Figure 3: described even light film 4 comprises a transparent plastic film (or thin slice) 61, be printed on a leaded light site 62 on the described transparent plastic film 61, described leaded light site 62 be by vary in size press the optical refraction principle and specific arrangement mode distributes, be imprinted on then on the transparent plastic film 61, when the light that light source sends propagates on the panel 5 equably through making light become after should sparing light film 4.

Referring to Fig. 4: be not a kind of embodiment of the present utility model among the figure, the principle of work of present embodiment and a last embodiment are same principle of work; Upper and lower at light source 2 all is respectively equipped with an even light film 4, and described even light film 4 is a plane by a pair of pull bar 8 with its tension, and the direction of the arrangement of this plane and light source fluorescent tube is on the same parallel surface, makes it to obtain two light-emitting areas with uniform light.
