Embodiment Construction

[0011] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] See figure 1 , the advertising billboard 10 provided by the embodiment of the present invention includes a light guide plate 11 , two light sources 12 , and a reflective sheet 13 .

[0013] The light guide plate 11 has two opposite light incident surfaces 110, a light exit surface 111 located between the two light incident surfaces 110, and a bottom surface 112 opposite to the light exit surface 111, located between the light exit surface 111 and the bottom surface 112 and connected to the two A side surface 113 adjacent to the light incident surface 110.

[0014] The light emitting surface 111 is provided with advertising graphics 14 such as characters and pictures. A plurality of optical microstructures 114 are disposed on the light emitting surface 111 at the edge of the advertising graphic 14 . In this embodiment, the pluralit...

Abstract

The invention relates to a billboard, comprising a light guide plate and at least one light source; wherein the light guide plate comprises at least one light incident plane and an light exit plane, the light source is arranged oppositely to the light incident plane, the light emitted by the light source is projected by the light incident plane into the light guide plate and exits via the light exit plane, the light exit plane is provided with advertisement graphics, a plurality of optical microstructures are arranged at the edges of the advertisement graphics of the light exit plane. The brightness of the light exit plane at the plurality of optical microstructures is higher than the brightness in the interior of the advertisement graphics, so that the advertisement graphics exhibit excellent stereoscopic vision effect due to comparison difference caused by the different brightness in the interior and at the edges of the advertisement graphics.

Description

technical field [0001] The invention relates to an advertising billboard, in particular to a luminous advertising billboard. Background technique [0002] At present, common advertising billboards are usually printed on canvas or canvas by printing, and light emitting diodes (Light Emitting Diode, LED) are used as light sources. A light emitting diode with high brightness can be found in Michael S.Shur et al. "Solid-State Lighting: Toward Superior Illumination" published in Proceedings of the IEEE, Vol.93, No.10 (October 2005). However, the advertising content on this advertising billboard is flat, and it mainly uses the design of color or pattern to form a sense of visual hierarchy, or uses the color hierarchy of the light source to enhance the visual effect to highlight the advertising content, but the advertising content of this advertising billboard The visual effect is not very ideal. [0003] In view of this, it is necessary to provide an advertising billboard with b...
