Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of frameless advertising light boxes, belong to the technical field of advertising light box. BACKGROUND

[0002] Advertising light box is a kind of equipment for showing advertisement, propagandizing information or brand image, which is usually placed in public places, such as both sides of street, shopping mall, subway station, airport and other places with large flow of people. It attracts the attention of passing pedestrians to deliver advertising information, so as to achieve the purpose of publicity and promotion.

[0003] At present, there are two common structures of advertising light box: one of them is fixed by using aluminum profile, then the light bar is pasted on the profile, and then the optical three-piece set is placed on the profile to reflect the light emitted by the light bar. This advertising light box has the following shortcomings: the width of the light box frame is usually 10mm, and the frame of the ultra-narrow frame light box is also 6mm. There is a height difference on the whole light-emitting surface, that is, the frame of the light box is 1mm higher than the light-emitting surface. For some specific occasions, such as occasions that require seamless display of advertising content, the frame looks very conspicuous, which affects the overall visual effect. The other is to use aluminum foil to wrap the edge, which uses double-sided tape to bond a circle of optical three-piece set around the edge, and then uses aluminum foil to bond the light bar to the side of the optical three-piece set. Although this advertising light box achieves a frameless structure and can be used in occasions that require seamless display of advertising content, it still has the following shortcomings when in use: in order to ensure the overall display effect, the thickness of the optical three-piece set used is relatively thick, which is 1.8-2cm, which has the problem of high cost. At the same time, there is an error in the width of the aluminum foil pasted by hand, which cannot form a straight line, and there is also the problem of not being beautiful enough. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a frameless advertising light box.

[0005] The technical scheme of the utility model is as follows:

A placing groove is formed around the light guide plate at the position of the peripheral edge of the top surface of the light guide plate. A light bar with a shape corresponding to the placing groove is arranged in the placing groove. The light-emitting part of the light bar is arranged at the inner side of the light bar. An aluminum foil is arranged on the outside of the light bar. The aluminum foil is bonded to the outside of the light bar. An edge sealing tape is arranged at the position of the peripheral edge of the bottom of the aluminum foil and extends inwardly. The edge sealing tape is bonded to the bottom wall of the reflective paper.

[0007] The shape and size of the light guide plate, the light diffusion plate and the reflective paper are adaptively arranged.

[0008] The dots on the top surface of the light guide plate are uniformly distributed on the light guide plate, the dots on the bottom surface of the light guide plate are gradually increased in size from the periphery to the middle of the light guide plate, and the dots on the bottom surface of the light guide plate are blanked at the edge position of the periphery of the light guide plate.

[0009] The lamp strip is vertically arranged in the placing groove.

[0010] The utility model has the advantages of the following beneficial effects:

[0011] 1. The utility model discloses a light guide plate, a light diffusion plate, a reflecting paper, a placing groove, a lamp strip and an aluminum foil paper are arranged to replace the traditional optical three-piece set of the frameless advertising lamp house, the thickness of the advertising lamp house provided by the utility model can reach about 1cm, compared with the traditional 1.8-2cm advertising lamp house, the utility model has the characteristics of saving materials and reducing cost, when working, the lamp strip starts to emit light after being electrified, part of the light emitted by the lamp strip will be emitted outward from the light diffusion plate through the light guide plate, and the other part of the light can change direction under the reflection of the reflecting paper and then be emitted outward from the light diffusion plate after passing through the light guide plate again, which can not only ensure the brightness, but also improve the uniformity of light emission, so that the traditional advertising lamp house can be replaced, compared with the prior art, the utility model has the advantages of saving cost, uniform light emission and more beautiful visual effect.

[0012] 2. The utility model discloses an edge sealing part is arranged at the bottom of the aluminum foil paper, and the edge sealing part is bonded with the bottom wall of the reflecting paper, which can not only prevent the light emitted by the lamp strip from leaking out from the gap between the reflecting paper and the light guide plate, but also limit the installation of the aluminum foil paper, so that the bonding position of the aluminum foil paper outside the lamp strip is limited and the phenomenon of skewing is difficult to occur, thereby ensuring the appearance.

[0013] 3. The utility model discloses an aluminum foil paper is used to fix the lamp strip, when the lamp strip needs to be replaced due to failure, the aluminum foil paper can be torn off to replace the lamp strip, and the whole operation is simple, so that the lamp strip can be conveniently replaced.
