Description

Integrated luminous mark

Technical Field

The invention relates to the field of signboard, in particular to an integrated luminous sign.

Background

The existing advertisement luminous sign is mostly of a box structure and comprises a bottom plate, an LED light source fixed on the bottom plate, a surrounding edge and a light-transmitting cover plate. Each complete luminous mark is composed of a plurality of independent small patterns or strokes, each independent small pattern or stroke is an independent light box, a light source is required to be arranged in each light box, all the small patterns or strokes are combined together according to corresponding coordinate positions to form a final pattern, and then power supplies of all the light boxes are connected together. Such a structure is manufactured, waste workers and wastes are time-consuming, and the process is complicated. If a small-sized luminous marker consisting of complicated and trivial small-sized strokes or small patterns is to be made, the steps of making the box body and arranging the light source and the power supply wiring in the box body are not only troublesome but also limited due to the limitation of the operating space: because the light source is required to be placed in the box body, the size of the box body cannot be smaller than that of the light source, and the box body is the biggest obstacle to manufacturing the small-size luminous mark.

The plate-shaped mark is made of transparent plate, and the pattern or character to be displayed is carved on the surface of the transparent plate, and the light emitted by the light source on the side of the plate is emitted into the transparent plate, so that the carved pattern emits light. Firstly, the luminous mark is only suitable for being used in a dark environment, such as an exit of a cinema and other marks, because the light absorption of the transparent plate and the carved patterns on the transparent plate is poor, the carved patterns can only slightly emit light compared with the transparent plate, and the whole vision is lack of aesthetic feeling and texture. Secondly, such luminous signs are only suitable for emitting a light color in all patterns. Finally, if stains or scratches are present on the surface of the transparent panel, the overall visual effect is compromised due to the transmission of light within the transparent panel.

By adopting the technical scheme, the technical scheme of the integrated luminous mark provided by the invention has the following positive effects:

firstly, the structure of the groove on the light guide plate is equivalent to the box body of the traditional luminous mark, the depth of the groove is equivalent to the thickness of the box body of the light box, because the light of the light source is transmitted transversely in the light guide plate, the inner walls (bottom surface and side wall) of the groove or nick all emit light in the form of a light emitting surface, and no light source is needed to be arranged in the groove, so that the light-transmitting piece butted with the groove can uniformly emit light no matter the depth of the groove or nick, and because no light source can realize the groove with any narrow and small size in the groove, the size of the luminous pattern is not limited, which is incomparable with the traditional light box luminous mark, the bottleneck that the luminous mark with the over-fine and over-complex pattern can not be manufactured in the process of manufacturing the luminous mark in the past is solved, and the light scattering mark pattern with the more fine.

Secondly, the problem that in the prior process of manufacturing the luminous identification, for complex patterns and complicated strokes, each part or each stroke needs to be independently provided with a light source in the box body is solved, and time and labor are wasted for the manufacturing and implementation process. The scheme regroups complex and broken patterns according to positions, light colors and required brightness, each group comprises a plurality of groups or strokes, each group corresponds to one light guide plate, namely the patterns and the strokes contained in the same group are taken as light sources by one light guide plate, the light source of one light guide plate is quite simple in arrangement and only needs to be arranged on the periphery of all the light scattering marks, and therefore the light source arrangement of the light-emitting mark is extremely simple and convenient, and the workload and the difficulty for arranging the light source are greatly reduced. And, all installation grooves that the light guide plate is located all are mutual isolation for luminous mutual noninterference, mutual independence between the light guide plate.

Finally, because the light guide plate of transparent material itself absorbs light very poorly, so this scheme provides the light source through the light guide plate and makes the printing opacity piece luminous, has utilized an experimental phenomenon, to the astigmatism trace on same light source and light guide plate and the light guide plate promptly, butt joint printing opacity piece on the astigmatism trace after, the light-emitting intensity of printing opacity piece is not butt joint printing opacity piece before the time astigmatism trace light-emitting intensity more than 2 times. The scheme positively utilizes the test result. The luminous intensity of the light-transmitting piece is ensured. And by utilizing the characteristic that the light guide plate is arranged in the mounting groove and the sealing property of the side groove wall of the mounting groove, light rays leaking from the peripheral section in the light guide plate are re-reflected back to the light guide plate by the groove wall, and the light is fully concentrated on the light scattering trace, dispersed and projected onto the butted light transmitting pieces. If higher luminous intensity is needed, the luminous intensity of the patterns and the strokes corresponding to each light guide plate can be increased by increasing the number of the light guide plates and reducing the number of the strokes corresponding to each light guide plate.

In the luminous mark, by utilizing the light guide principle of a transparent material and utilizing the corresponding astigmatism marks arranged on the light guide plate, light transversely transmitted by the astigmatism marks is folded to 90 degrees and then is scattered vertical to the plate surface, and then light longitudinally scattered on the astigmatism marks is concentrated on the light transmitting piece to be displayed by utilizing the light transmitting piece with good light absorption and light transmission characteristics, so that the defect of insufficient light emission caused by poor light absorption characteristics of the traditional transparent plate and the astigmatism marks is overcome; because the light source is intensively arranged at the periphery of the light guide plate, the number of the light source can be more or less, the light source is arranged at the luminous intensity of the light transmission part related to the number of the light source, the light source indirectly irradiates the light transmission part through the light scattering marks, and all light longitudinally scattered out through the light scattering marks is uniform light without light spots. The luminous sign light source that has improved traditional lamp house structure can only depend on the application defect in the box, leads to the light source quantity big, and the box is heavy, and processing is loaded down with trivial details.

The light-transmitting piece arranged on the front surface of the panel can be made into a light-transmitting piece with a certain thickness, a certain height or different light transmittance and a certain light transmittance color according to the effect requirement, for example, the light-transmitting piece made of a transparent material with a certain thickness or the light-transmitting piece combined by the transparent material and the transparent material together form a multi-layer concave-convex three-dimensional luminous effect together with the light-transmitting piece lined on the back surface of the back plate, so that the light-transmitting pieces in various forms are matched with the hollow grooves of the light-transmitting piece without butt joint on the panel, and the whole luminous mark can visually realize different brightness and light colors of corresponding parts of the luminous pattern by the light-transmitting pieces or the luminous pattern formed by the hollow grooves, can embody concave-convex three-dimensional effect and hierarchical effect and can make a luminous mark with.
