Description
Technical field
The utility model relates to advertising lamp box commercial and the public good propaganda, is specifically related to a kind of advertising lamp box of scalable picture light and shade.
Background technology
At present; Public place is used for doing the advertising lamp box that light is housed in advertising lamp box, the especially case of commercial and public good propaganda; Mostly can not regulate the advertisement picture light and shade, and the businessman that has can produce special effect for advertisement, and to the light and shade requirement to some extent of advertisement picture.Though also some advertising lamp box can be accomplished, it is through the Application and Development software program, and customized special circuit board is controlled the led light source that is equipped with in the case and to be realized.Its development difficulty is big, cost of manufacture is very high, therefore makes businessman that the price of this type of advertising lamp box is difficult to accept.
The utility model content
The purpose of the utility model provides a kind of advertising lamp box of scalable picture light and shade; Its automatic rotating device through being provided with; Rush down the intensity of light outside in rotary course, changing; Make advertisement picture produce the artistic effect of light and shade gradual change conversion, this advertising lamp box is simple and practical, cost of manufacture is low, has solved the problems referred to above that existing advertising lamp box exists.
The technical scheme that the utility model adopted is; A kind of advertising lamp box of scalable picture light and shade; Comprise lamp box face shield, lamp box backboard, and be contained in the lamphouse light source on the lamp box backboard, in the lamp box face shield of said lamp box backboard light source front; Be provided with one the transparent mounting bracket of central rotating shaft is housed; The mounting bracket lower left is provided with a drive motor that transmission gear is housed, the engagement of edge teeth that the transparent rotating disk outer rim of installing on described transmission gear and the mounting bracket central rotating shaft is provided with, be stained with in the front of said transparent rotating disk one with the big or small identical rotation light polarizing film of lamp box face shield key frame; In the front of rotating light polarizing film, the back of key frame is provided with a fixedly light polarizing film on the lamp box face shield.
The advertising lamp box of the described scalable picture of the utility model light and shade, its characteristic also be, said rotation light polarizing film and fixing light polarizing film are that polarizing angle is consistent, the parallel circular light polarizing film of wafer in the light polarizing film.
Said lamp box face shield is a transparent material, back side silk-screen or post ads picture.
The advertising lamp box of the utility model scalable picture light and shade; Lamphouse light source through on the dress lamp box backboard sees through transparent mounting bracket; Through rotating light polarizing film and fixing light polarizing film, light is impinged upon on the key frame of lamp box face shield, the transmission gear through drive motor drives the rotation light polarizing film with transparent dial rotation; Because the wafer that rotates light polarizing film and fixing light polarizing film is by parallel slowly rotary shifted; Lamphouse light source impinges upon the light of lamp box face shield key frame gradually by bright deepening, again by secretly brightening, forms a kind of artistic effect that can regulate advertising lamp box picture light and shade gradual change conversion.Played the eye that attracts masses, improved the attention rate actual effect of people commodity or public service ads.
Description of drawings
Fig. 1 is the advertising lamp box structural representation of the utility model scalable picture light and shade;
Fig. 2 a, Fig. 2 b, Fig. 2 c are that the advertising lamp box of scalable picture light and shade rotates light polarizing film and turns round the printing opacity principle schematic with fixing light polarizing film.
Among the figure, 1. lamp box face shield, 2. lamp box backboard, 3. lamphouse light source, 4. mounting bracket, 5. transmission gear, 6. drive motor, 7. transparent rotating disk 8. rotates light polarizing film, 9. fixedly light polarizing film, 10. key frame.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
A kind of advertising lamp box of scalable picture light and shade; As shown in Figure 1; Comprise lamp box face shield 1, lamp box backboard 2; And be contained in the lamphouse light source 3 on the lamp box backboard 2, in the lamp box face shield 1 of said lamp box backboard 2 light sources 3 fronts, be provided with one central rotating shaft and transparent mounting bracket 4 are housed; Mounting bracket 4 lower lefts are provided with a drive motor 6 that transmission gear 5 is housed; Edge teeth's engagement that transparent rotating disk 7 outer rims of installing on described transmission gear 5 and mounting bracket 4 central rotating shafts are provided with, be stained with in the front of said transparent rotating disk 7 one with the identical rotation light polarizing film 8 of lamp box face shield 1 key frame, 10 sizes, in the front of rotation light polarizing film 8; The back of key frame 10 is provided with a fixedly light polarizing film 9 on lamp box face shield 1, and said rotation light polarizing film 8 and fixing light polarizing film 9 are that polarizing angle is consistent, the parallel circular light polarizing film of wafer in the light polarizing film.Said lamp box face shield 1 is a transparent material, back side silk-screen or post ads picture.
