Detailed Description
In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1 and 2, a borderless ultrathin lamp box comprises a bottom plate 1, a light guide plate 2 and a pattern layer 3 which are sequentially arranged from bottom to top. The present embodiment may be secured by gluing, snap-fit or locking. The base plate 1 is made of an opaque material. The light guide plate 2 is made of a light transmitting material, and the light guide plate 2 is provided with grooves 4 along the edges. In this embodiment, the light guide plate 2 is a light-transmitting adhesive plate. A lamp strip 5 is arranged in the groove 4, specifically, the back surface of the lamp strip 5 is adhered to the side wall of the groove 4, and the light emitting surface of the lamp strip 5 faces the center. The lamp strip 5 is started by external power supply. The wires of the strip 5 can be led out from the back of the base plate 1. In this embodiment, the pattern layer 3 may be sprayed or printed on the top surface of the light guide plate 2. The lamp strip 5 is adhered in the groove 4, and then other plate layers are sequentially placed and assembled. In addition, the technical level requirements of assembly personnel are low, the assembly efficiency is high, and the yield is extremely high.
Compared with the prior art, the embodiment has the advantages of fewer parts, ingenious, simple and reliable structure, convenient assembly, lower overall cost, thinner finished product thickness, and no frame, and the edge of the light guide plate 2 can emit light, so that the whole is more attractive and has layering sense.
Further, an advertisement board 6 is disposed between the light guide plate 2 and the pattern layer 3, and the advertisement board 6 is made of a light-transmitting material, in this embodiment, the advertisement board 6 is a transparent glue board. The pattern layer 3 is disposed on the upper surface of the advertisement board 6. Specifically, the pattern layer 3 may be sprayed or printed on the upper surface of the advertisement board 6. The present embodiment is designed such that the advertisement board 6 can be directly replaced when the advertisement needs to be replaced.
Further, the bottom plate 1 is a black reflector, and a mirror surface layer 7 is disposed on the upper surface of the bottom plate 1. The mirror layer 7 is adhered and fixed with the bottom plate 1. By adopting the design of the embodiment, more light can be reflected to the pattern layer 3, so that the brightness of the pattern layer 3 is higher and more uniform.
Further, the groove 4 is disposed at a lower portion of the light guide plate 2. The grooves 4 are arranged at the lower part of the light guide plate 2, so that the overall light effect is more uniform, and the brightness of the position of the lamp strip 5 close to the pattern layer 3 is reduced.
Referring to fig. 2, further, the base plate 1, the light guide plate 2 and the advertisement plate 6 are fixedly connected by a locking member. Specifically, the locking member may be a combination of a bolt 8 and a nut, and the base plate 1, the light guide plate 2 and the advertisement plate 6 are provided with through holes at corresponding positions, and the locking member passes through the through holes to fix the base plate 1, the light guide plate 2 and the advertisement plate 6 together. The design of the embodiment is more convenient to assemble.
Further, the locking piece comprises a bolt 8, a flat nut column 9 and a soft rubber cushion ring 10. The soft rubber gasket 10 is arranged between the flat nut column 9 and the bottom plate 1. The use of the soft rubber gasket 10 and the flat nut post 9 in this embodiment prevents the threads of the bolt 8 from scraping the individual plies.
Further, the edge of the light guide plate 2 is provided with a flange 11 formed by extending the body outwards, and the cross section of the flange 11 is in a reverse right trapezoid shape. The design of the embodiment is more obvious in edge light emission, stronger in light effect layering and more attractive.
Further, the inclined surface of the flange 11 is a frosted surface 12. The frosted surface 12 can make the light effect of the edge of the embodiment softer.
Further, a light shielding region 13 is disposed along the edge of the pattern layer 3, and the light shielding region 13 is disposed right above the light band 5. In this embodiment, the light shielding area 13 is a black coating, and is used for shielding the strong light near the lamp strip 5, so that the overall light effect is more uniform. The locking piece can be arranged in the shading area 13, and the color of the locking piece is the same as that of the shading area 13, so that the overall light effect and layering sense of the product are better.
The above embodiments do not limit the protection scope of the utility model, and those skilled in the art can make equivalent modifications and variations without departing from the whole inventive concept, and they still fall within the scope of the utility model.
