[0032] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0033] Please refer to Figure 1-Figure 5 The utility model discloses an LED light billboard, and the specific technical solution is described as follows:

[0034] The main structure of the billboard includes a sheet metal frame 1, an LED light group 3 and a transparent panel 6, wherein Figure 1The sheet metal frame 1 has a slot inside, into which a transparent panel 6 can be inserted. The slot opening is covered with a cover 7, which is equipped with a permanent magnet for attracting the sheet metal frame 1, thereby sealing the transparent panel 6. A heat sink 2 is sealed on the back of the sheet metal frame 1. The heat sink 2, sheet metal frame 1, and cover 7 form a sealed, integrated structure to ensure waterproofing. The bottom of the sheet metal frame 1 is equipped with movable components, such as universal wheels or a bracket, to facilitate the placement of the billboard in any location.

[0035] In this embodiment, if Figure 2 , an LED light group 3 and a photovoltaic module 5 are installed on the heat sink 2, wherein the photovoltaic module 5 is connected to the LED light group 3, thereby lighting the LED light group 3 to illuminate the transparent panel 6, and the surface of the transparent panel 6 is affixed with advertising paper, and the advertising paper is suitable for being attached to the transparent panel 6 and inserted from the sheet metal frame 1, thereby displaying the advertising content at night through the illumination of the LED light group 3. Moreover, in this embodiment, the surface of the LED light group 3 is covered with a light guide plate 4, and the light guide plate 4 is made of translucent plastic material, and is doped with fluorescent agent in the material. The fluorescent agent emits a balanced soft light after being irradiated by light, which can illuminate the advertising paper, thereby improving the viewing effect of the advertising paper. Moreover, a frosted layer 8 is provided on the surface of the light guide plate 4, such as Figure 4 The frosted layer 8 improves the diffuse reflection of light, thereby avoiding light concentration, reducing eye irritation, and making it easier for people to read advertising information at night. In addition, the light guide plate 4 and photovoltaic panel 51 are both attached to the sheet metal frame 1, and a photovoltaic panel 51 is installed on top of the light guide plate 4 to prevent the light guide plate 4 and photovoltaic panel 51 from falling off.

[0036] In some embodiments, as Figure 3 The photovoltaic assembly 5 includes a photovoltaic panel 51 and a control board 53. The control board 53 is provided with a power supply voltage stabilization circuit. The photovoltaic panel 51 is directly connected to the battery 52 circuit, thereby converting solar energy into electrical energy and charging the battery 52. ​​The battery 52 supplies power to the LED light group 3 through the power supply voltage stabilization circuit, thereby lighting the light strip. At the same time, a photosensitive switch is connected between the battery 52 and the power supply voltage stabilization circuit of the control board 53. At night or when there is insufficient light outside, the photosensitive switch automatically closes, thereby lighting the LED light group 3, thereby lighting the light strip at night.

[0037] In this embodiment, as an optional solution, a delayed voice-activated switch is installed on the heat sink 2. The delayed voice-activated switch is arranged in series between the photovoltaic component 5 and the LED light group 3. When a sound is emitted near the LED light billboard, such as when a person or a vehicle passes by, the delayed voice-activated switch will be closed for a period of time, and the light group will illuminate the billboard for pedestrians to see. This can not only attract the attention of passers-by at night, but also effectively reduce battery consumption and reduce the battery selection cost.

[0038] As another optional solution, the LED light group 3 is composed of several parallel light strips, wherein the several light strips are connected to the single-chip microcomputer, and any light strip is controlled by the single-chip microcomputer. Specifically, after dusk outdoors, as time goes by, the light gradually weakens and disappears until the sky gradually brightens in the late night and early morning. During this process, a timer can be set in the single-chip microcomputer to light up some of the light strips in the LED light group 3 at regular intervals until all the light strips are lit in the late night and then gradually extinguished in the early morning.

[0039] The following C51 MCU program code is used as an example to illustrate how setting a timer can achieve the above technical effects:

[0040]

[0041]

[0042] This can further achieve the effect of energy saving, and at the same time can keep the lighting balanced, which is beneficial for passers-by to watch advertisements at night.

[0043] In some embodiments, as Figure 2 The back side of the heat sink 2 is provided with reinforcing ribs, which can increase the contact area between the heat sink 2 and the air, and at the same time improve the structural strength of the heat sink 2 to prevent the heat sink 2 from being deformed by heat.

[0044] Optionally, the edge of the transparent panel 6 is hinged to the sheet metal frame 1, so that the transparent panel 6 can be opened directly from the billboard to facilitate the placement of advertising paper.

[0045] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
