The embodiment of the invention provides a lamp box. The lamp box can be applied to outdoor large billboards or merchant stores to transmit merchant information to users.

As shown in fig. 1, the lamp box 100 includes a lamp box cloth 10 and a frame 20. The frame 20 may be made of metal, plastic or wood plate. The outer contour of the frame 20 may be a rectangular parallelepiped. In some embodiments, the outer contour of the frame 20 may also be other shapes such as a sphere.

The lamp house cloth 10 is mounted on the frame 20. Wherein the lamp house cloth 10 may cover a portion of the surface of the frame 20. For example, when the frame 20 is a rectangular parallelepiped frame, the cabinet cloth 10 may cover one surface of the frame 20.

In some embodiments, the surface of the frame 20 covered with the light box cloth 10 may also be provided with a glass layer. The glass layer can press the lamp house cloth 10 against the surface of the frame 20 while providing protection to the lamp house cloth 10.

In some embodiments, as shown in fig. 2, the light box 100 further includes a light source 30. The light source 30 is installed inside the frame 20. The light source 30 may be a point light source, a surface light source, or the like. The lamp house cloth 10 has light transmittance. When the external ambient light is dark at night or during the day, the light source 30 is turned on to emit visible light to the outside through the lamp house cloth 10, thereby improving the visibility of the lamp house 100.

In some embodiments, the light source 30 may be a surface light source formed of a plurality of light emitting diodes. The light source 30 includes a plurality of light emitting diodes 31 disposed apart from each other. The surface light source 30 formed of a plurality of light emitting diodes may be disposed in parallel with the lamp housing cloth 10. The light emitting surface of the light source 30 faces the lamp house cloth 10.

In some embodiments, as shown in fig. 3, the light source 30 may be a surface light source formed of a plurality of light emitting diodes. The light source 30 includes a plurality of light emitting diodes 31 disposed apart from each other. A surface light source 30 formed of a plurality of light emitting diodes may be disposed on a sidewall of the lamp box 100. That is, the surface light source 30 and the lamp house cloth 10 are perpendicular to each other. The leds 31 in the light source 30 may be arranged at an angle. For example, the light emitting diode 31 forms an angle of 30 degrees with the plane in which the light source 30 is located. The light emitted from the light source 30 is directed toward the lamp housing cloth 10. When the external ambient light is dark at night or during the day, the light source 30 is turned on to emit visible light to the outside through the lamp house cloth 10, thereby improving the visibility of the lamp house 100.

In some embodiments, as shown in fig. 4, the light source 30 may be a surface light source formed of a plurality of light emitting diodes. The light source 30 includes a plurality of light emitting diodes 31 arranged spaced apart from each other. Among them, the light source 30 may include a first portion 301 disposed parallel to the cabinet cloth 10 and a second portion 302 disposed perpendicular to the cabinet cloth 10. The light emitting surface of the first portion 301 faces the lamp house cloth 10. The leds 31 in the second portion 302 may be arranged at an angle. For example, the light emitting diode 31 forms an angle of 30 degrees with the plane in which the second portion 302 lies. So that the light emitted from the second portion 302 is also directed toward the lamp house cloth 10.

In some embodiments, as shown in fig. 5, the light box 100 further includes a control circuit 40. The control circuit 40 is mounted inside the frame 20. The control circuit 40 is connected to the light source 30. The control circuit 40 is used to control the light source 30 to be turned on and off. For example, the user may set the times at which the light source 30 is turned on and off. When the time reaches the preset turn-on time, the control circuit 40 controls the light source 30 to turn on. So that the light source 30 emits visible light to the outside through the lamp box cloth 10, thereby improving visibility of the lamp box 100. When the time reaches the preset turning-off time, the control circuit 40 controls the light source 30 to be turned off so as to save electric energy.

In some embodiments, as shown in fig. 6, light box 100 also includes an ambient light sensor 50. An ambient light sensor 50 is mounted inside the frame 20. The ambient light sensor may also be referred to as an ambient light sensor. The ambient light sensor 50 is used to detect the intensity of the external ambient light.

In some embodiments, the ambient light sensor 50 is connected to the control circuit 40 to input an ambient light intensity signal detected by the ambient light sensor 50 into the control circuit 40. The control circuit 40 may include a comparison circuit, among others. The comparison circuit is used for comparing the signal input by the ambient light sensor 50 with a preset signal. When the ambient light intensity value detected by the ambient light sensor 50 is smaller than the preset threshold, it indicates that the external environment is dark, and at this time, the control circuit 40 controls the light source 30 to be turned on; when the ambient light intensity value detected by the ambient light sensor 50 is greater than or equal to the preset threshold, it indicates that the external environment is bright, and the control circuit 40 controls the light source 30 to turn off.

The preset threshold may be a preset ambient light intensity value. For example, the preset threshold may be 500. When the ambient light intensity value detected by the ambient light sensor 50 is less than 500, the control circuit 40 controls the light source 30 to be turned on; when the ambient light intensity value detected by the ambient light sensor 50 is greater than or equal to 500, the control circuit 40 controls the light source 30 to turn off.

In some embodiments, the light box 100 may be connected to a back-end processor. The ambient light sensor 50 and the control circuit 40 may be electrically connected to the processor. The ambient light sensor 50 sends the detected ambient brightness information to the processor. A preset threshold value may be pre-stored in the processor. The predetermined threshold may be an ambient light intensity value. When the processor determines that the ambient light brightness value is smaller than the preset threshold, the processor sends a start signal to the control circuit 40, so that the control circuit 40 controls the light source 30 to start; when the processor determines that the ambient light brightness value is greater than or equal to the preset threshold, it sends a turn-off signal to the control circuit 40, so that the control circuit 40 controls the light source 30 to turn off.

In some embodiments, the control circuit 40 is further configured to control the light intensity of the light source 30 according to the ambient brightness value detected by the ambient light sensor 50 when the light source 30 is turned on. For example, when the light source 30 is turned on, the control circuit 40 gradually increases the light emission intensity of the light source 30 according to an increase in the ambient brightness value.

In some embodiments, when the light source 30 includes a plurality of light emitting diodes 31, the control circuit 40 controls the number of light emitting diodes lit in the light source 30 according to the ambient brightness value. For example, when the light source 30 includes 200 light emitting diodes, the control circuit 40 may control the number of light emitting diodes that are lit according to the correspondence shown in table 1:

TABLE 1

Referring to fig. 7, fig. 7 is a longitudinal sectional view of a lamp box cloth 10 according to an embodiment of the present invention. The lamp box cloth 10 includes a film layer 11, a reflection layer 12, a substrate layer 13, a cloth layer 14, and a first binder 16 disposed between the substrate layer 13 and the cloth layer 14. The film layer 11, the reflective layer 12, the substrate layer 13 and the cloth layer 14 are sequentially stacked. The substrate layer 13 and the fabric layer 14 are bonded to each other by the first adhesive 16.

The thin film layer 11 is a thin film that allows visible light to pass therethrough. The material of the film layer 11 may be polyethylene, polypropylene, polyvinyl chloride, polystyrene, resin, or the like. The thin film layer 11 covers the reflective layer 12. The thin film layer 11 may provide protection to the reflective layer 12. For example, the thin film layer 11 may provide a dust-proof function to the reflective layer 12, and the thin film layer 11 may insulate the reflective layer 12 from air to provide the reflective layer 12 with a corrosion-proof function. In some embodiments, the film layer 11 may be a transparent film.

In some embodiments, toner may be added to the film layer 11 so that the film layer 11 appears green or blue. So that the color of the entire lamp house cloth 10 also appears to be the same as the color of the film layer 11.

The reflective layer 12 may transmit visible light emitted by the light source 30 inside the light box 100. The material of the reflective layer 12 includes metal. The reflective layer 12 may be provided on the base material layer 13 by vacuum deposition or vacuum magnetron sputtering, so that the reflective layer 12 has a reflective effect on visible light. When the visible light is reflected by the reflective layer 12, the surface of the lamp house cloth 10 exhibits at least a metallic luster. Metallic luster refers to the luster reflected by a surface after metal polishing.

In some embodiments, the material of the reflective layer 12 includes a metal having a high reflectivity to visible light. Wherein the reflective layer 12 may comprise one or more of chromium, aluminum, silver, and nickel. For example, the reflective layer 12 may be an alloy of aluminum and silver. In some embodiments, non-metallic materials may also be added to the reflective layer 12.

The base material layer 13 may transmit visible light. The base material layer 13 provides a substrate necessary for adhesion to the reflective layer 12. Referring to fig. 8 together, fig. 8 is a sectional view of the lamp box cloth 10 shown in fig. 7 in the P-P direction. Wherein, the substrate layer 13 is provided with a micro hole 131 on one side close to the cloth layer 14. It will be appreciated that the number of micro holes 131 may be plural. When the substrate layer 13 and the fabric layer 14 are bonded to each other by the first adhesive 16, at least a part of the first adhesive 16 is located in the micro hole 131.

When the substrate layer 13 and the fabric layer 14 are bonded to each other, the first binder 16 can permeate into the micro holes 131, so that the bonding strength between the substrate layer 13 and the fabric layer 14 can be enhanced, and the stability of the lamp box fabric 10 is improved.

In some embodiments, the material of the substrate layer 13 is polyvinyl chloride. In some embodiments, a toner may be added to the substrate layer 13 such that the substrate layer 13 exhibits the same color as the thin film layer 11. When the film layer 11 is a transparent film, the entire color of the lamp house cloth 10 is the same as the color of the base material layer 13.

The layer of fabric 14 may be transparent to visible light. The material of the fabric layer 14 may be fiber, polyester (dacron), polyamide (nylon, also called chinlon), polyacrylonitrile (acrylon), polyurethane (spandex), etc.

Since the reflective layer 12 is provided in the lamp house cloth 10, the lamp house cloth 10 can reflect external light, so that the surface of the lamp house cloth 10 can exhibit metallic luster. The cabinet cloth 10 can exhibit a gradual color effect when viewed from different angles outside the cabinet cloth 10.

In some embodiments, the film layer 11, the reflective layer 12, and the substrate layer 13 may be bonded in an irreversible manner by an adhesive to form a light-transmissive film layer 15. The irreversible means that the thin film layer 11, the reflective layer 12, and the base material layer 13 cannot be separated again after the light-transmitting film layer 15 is formed.

In some embodiments, as shown in fig. 9, the micro-holes 131 are through-holes that extend through the substrate layer 13. Thus, the first adhesive 16 can contact the reflective layer 12 through the micro holes 131, further enhancing the adhesive strength between the substrate layer 13 and the fabric layer 14.

In some embodiments, as shown in FIG. 10, a second adhesive 17 is disposed between the film layer 11 and the reflective layer 12. The film layer 11 and the reflective layer 12 are bonded together by a second adhesive 17. Wherein, the thin film layer 11, the second adhesive 17, the reflective layer 12 and the base material layer 13 are bonded to form the light-transmitting film layer 15.

In some embodiments, the side of the reflective layer 12 adjacent to the thin-film layer 11 is provided with micro-holes 121. It is understood that the number of the micro holes 121 may be plural. When the thin-film layer 11 and the reflective layer 12 are bonded to each other by the second adhesive 17, at least a part of the second adhesive 17 is located in the micro-holes 121.

Since the second adhesive 17 can penetrate into the micro holes 121 when the thin film layer 11 and the reflective layer 12 are adhered to each other, the adhesion strength between the thin film layer 11 and the reflective layer 12 can be enhanced, and the stability of the lamp case fabric 10 can be improved.

In some embodiments, as shown in FIG. 11, the micro-holes 121 are through-holes that extend through the reflective layer 12. Thus, the second adhesive 17 can contact the base material layer 13 or the first adhesive 16 through the micro holes 121, further enhancing the adhesive strength between the thin film layer 11 and the reflective layer 12.

The light box cloth and the light box provided by the embodiment of the invention are described in detail, the principle and the embodiment of the invention are explained by applying a specific embodiment, and the description of the embodiment is only used for helping understanding the invention. Meanwhile, for those skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed, and in summary, the content of the present specification should not be construed as limiting the present invention.
