Description

Signboard

Technical Field

The utility model relates to the technical field of light markers, in particular to a signboard.

Background

The existing sign usually includes a nameplate and a backlight plate, which are disposed opposite to each other, and the nameplate is provided with a through hole having a characteristic shape (such as a character shape or a pattern shape) based on specific sign contents. However, most of the existing backlight plates adopt LED lamp beads, and the light of the light source is strong, so that the LED lamp beads can feel dazzling when being used for observing through holes of a nameplate. In order to solve the above problems, a method commonly used at present is to arrange a diffusion sheet or a light guide plate on the LED beads of the backlight plate, so that the light of the backlight plate becomes soft. However, the LED lamp beads themselves generate heat when working, so that the diffusion sheet or the light guide plate needs to be lifted up by an additional supporting structure in order to prevent the diffusion sheet or the light guide plate from being deformed due to direct contact with the LED lamp beads, thereby increasing the difficulty in manufacturing the signboard.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the drawings and described in accordance with the drawings are exemplary only, and the utility model is not limited to these embodiments.

It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the scheme according to the present invention are shown in the drawings, and other details not so relevant to the present invention are omitted.

In view of the problems of the prior art mentioned in the background, the present invention provides the following embodiments.

As shown in fig. 1, the signboard provided in the present embodiment includes a nameplate 1 and a backlight plate 2 disposed opposite to each other. The nameplate 1 is provided with a plurality of through holes 11 with preset shapes, and the through holes 11 can adopt specific character models and patterns. The backlight plate 2 is used for irradiating light to the through holes 11, the backlight plate 2 comprises a circuit substrate 21 and a plurality of LED lamp beads 22 arranged on the circuit substrate 21, and the LED lamp beads 22 are respectively arranged opposite to the through holes 11. A light diffusion layer 12 is arranged in the through hole 11, and when light generated by the backlight plate 2 passes through the light diffusion layer 12, the light becomes uniform scattered light under the optical atomization effect of the light diffusion layer 12. Preferably, the light diffusion layer 12 of the present embodiment is solidified from white printing ink. Specifically, when the light diffusion layer 12 of the present embodiment is formed, a plate may be used to cover one side of the nameplate 1, so that one side of the through hole 11 is completely closed, and then the other side of the nameplate 1 is coated with printing ink, and then the printing ink is cured to form the light diffusion layer 12. Since the printing ink is easy to apply and the curing speed is fast, the manufacturing time can be reduced by using the printing ink to form the light diffusion layer 12. Of course, the light diffusion layer 12 may be made of other known materials (e.g., acryl material), but an additional process is required to correspond to the shape of the through hole 11.

Further, as shown in fig. 1, a plurality of lenses 13 respectively covering the plurality of through holes 11 are disposed on a side of the name plate 1 facing away from the backlight plate 2. The lens 13 comprises a convex surface facing away from the inscription plate 1 and a flat surface facing the inscription plate 1. After the lens 13 is arranged on the through hole 11, the characters or patterns of the signboard combination of the embodiment can be more obvious through the magnifying effect of the lens 13. The process of applying the printing ink may be performed by covering the plurality of through holes 11 with the lenses 13.

Further, as shown in fig. 1, a transparent support plate 14 is disposed on a side of the nameplate 1 facing the backlight plate 2, and the transparent support plate 14 is used for covering the plurality of through holes 11. In this embodiment, the transparent support plate 14 may be disposed after the printing ink is applied. Optionally, a plurality of prisms 14a are arranged on a side of the transparent support plate 14 facing the backlight plate 2, and orthographic projections of the prisms 14a on the nameplate 1 cover the through holes 11, or as shown in fig. 2, a plurality of transparent bumps 14b are arranged on a side of the transparent support plate 14 facing the backlight plate 2, and orthographic projections of the transparent bumps 14b on the nameplate 1 respectively cover the through holes 11. The prisms 14a and the transparent bumps 14b have a certain light-gathering effect, so that the brightness of the characters or patterns of the signboard structure of the embodiment can be improved.
