Embodiment 1

[0024] The imaging of the advertising light box in this embodiment includes a background area A 1 , i.e. white background color; and two pattern areas (i.e. N=2): the first pattern area A 2 , that is, the red "lamp" character pattern, and the second pattern area A 3 , that is, the blue "box" pattern. The advertising light box includes three light source layers stacked from front to back, that is, the first light source layer 1 emitting white light, the second light source layer 3 emitting red light and the third light source layer 5 emitting blue light. The light source layer is an acrylic board, the backlight is located on the side of the acrylic board, and the light propagates along the surface of the acrylic board. There are technologies, so I won't repeat them here. The order from front to back mentioned here means that the observer faces the front of the molded advertising light box to observe, that is, the first layer is the first light source layer 1, followed by the...

Embodiment 2

[0031] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that an additional structure is provided between the light source layer 3 and the light-shielding paper 4. The additional structure is an additional light source with the same layout as the light source layer 3 but different colors. Layer 6. The same layout as mentioned here means that the light source layer 6 is provided with the diffuse reflection area B on the light source layer 3 1 ’ the same diffuse reflection area B 1 ". Then, the "辶" character pattern can be illuminated by two background layers of different colors, and can also be illuminated by two background layers at the same time, forming the effect of spectral superposition.

[0032] The additional structure consists of one or more additional light source layers with the same layout but different colors. Multiple additional structures can also be included in one advertising light box.

[0033] In addition, the distribut...

Abstract

The invention discloses an advertising light box. The image of the advertising light box comprises a background zone and N pattern zones. From front to back, the advertising light box is at least provided with N+1 light source layers in a laminating way, namely, a first light source layer, a second light source layer, ..., and an (N+1)th light source layer, wherein N is a natural number more than or equal to 2; the first light source layer is a background layer; N diffuse reflection zones are formed on the first light source layer, and correspond to the N pattern zones; N-1 diffuse reflection zones are formed on the second light source layer, and correspond to N-1 pattern zones; no diffuse reflection layers are formed on the (N+1)th light source layer; a shading layer is arranged between every two adjacent light source layers; hollowed photic zones are formed on the shading layer, and correspond to the diffuse reflection zones on the former light source layer adjacent to the shading layer; the first light source layer provides a light source for the backlight zone; and the second to (N+1)th light source layers provide the light sources for the corresponding one of the N pattern zones respectively.

Description

technical field [0001] The invention relates to an advertising light box, in particular to an advertising light box with patterns and colors that can flash synchronously or alternately. Background technique [0002] At present, most advertising light boxes use single-color LED (light-emitting diode) lamps as the light source of the light guide plate, or use two or three LED lights of different colors arranged at intervals to form a composite light source set on the light guide plate, and through a unified power supply Control LED lights of different colors to turn on or off at the same time. This composite light source overcomes the defect of single background color of the original light guide plate. Although this type of composite light source makes the background color have multiple colors, it cannot produce dynamic effects and cannot overcome the defect of lack of dynamic feeling in existing advertising light boxes. Contents of the invention [0003] The technical prob...
