Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a novel outdoor energy-saving bare-mounted cold screen. Background Art

[0002] Currently, there are the following problems in the installation process of outdoor LED displays:

[0003] Poor heat dissipation: In outdoor environments, integrated circuits overheat and fail, and light decay accelerates, requiring forced heat dissipation using air conditioners and fans. However, outdoor LED displays are usually installed on the exterior walls of buildings, without sufficient ventilation space.

[0004] Increased energy consumption: Outdoor LED displays usually have increased brightness. Long-term high-brightness operation leads to a sharp increase in energy consumption. At the same time, the heat generated by high brightness also increases sharply, and the energy consumption of air conditioners or fans also increases accordingly.

[0005] To address the heat dissipation issues of outdoor LED displays, traditional methods involve installing air conditioners or fans on the back of the screen. To ensure effective heat dissipation, the air conditioner or fan vents must be regularly cleaned to prevent blockage. While this approach lowers the screen's temperature, the prolonged operation of the air conditioner or fan results in a significant increase in energy consumption and maintenance costs.

[0006] To reduce energy consumption on outdoor LED displays, light sensors are often installed or the brightness is manually set based on the duration of sunlight exposure. Light sensors detect strong light and increase the brightness to enhance the display, but this can significantly increase power consumption. Manual brightness settings can be adjusted based on the season and duration of sunlight exposure, but they require significant manpower and material resources, increasing labor costs.

[0007] In order to solve the above problems, the present invention proposes a novel outdoor energy-saving bare-mounted cooling screen. Summary of the Invention

[0017] When the control motherboard finds that the light intensity is the highest at a certain angle, it issues a command to control the driving element to drive the guide bearing, thereby controlling the perovskite solar cell to turn to the angle with the highest light intensity.

[0018] The display screen box includes an integrally formed die-cast aluminum frame and an aluminum bottom shell. The outer layer of the die-cast aluminum frame is coated with moisture-proof, dust-proof and corrosion-resistant three-proof paint.

[0019] The display unit includes a die-cast aluminum bottom shell, a light board and a dual-voltage low-voltage power supply system.

The guide bearing is controlled and powered by the control host; the louver structure will move with the sunlight, and the direction is the area of strong light exposure, so as to achieve efficient power generation, supplement the power required by the display screen, and reduce electricity bills.

[0023] According to user needs, you can customize the selection of a single display unit for independent display, several display units to form a complete display screen combination display, or divide it into custom divided display areas, each area plays its own display screen.

[0024] The beneficial effects of the present invention are as follows: the new outdoor energy-saving bare-mounted cold screen uses a box material with good thermal conductivity and a heat dissipation structure of the display unit rear shell, which effectively solves the heat dissipation problem; at the same time, through the reasonable layout of the displacement structure of the solar cells, the light energy conversion efficiency is maximized and the power consumption of the screen is reduced.

[0029] The novel outdoor energy-saving bare cold screen comprises a display box 4, a solar cell 1 and a photosensitive element 6;

[0030] Several display units 7 are fixedly installed in the display screen box 4;

[0031] The solar cell 1 includes a solar panel, a guide bearing 2 and a support rod 3, and is suspended on the top of the display box 4 using a louver structure. It is connected to the display box 4 through the guide bearing 2 and the support rod 3 to supply power to the display unit 7.

[0032] The photosensitive elements 6 are all light sensors, which are arranged along the length of the display screen box and are located above the solar cell 1. The output end is connected to the signal output end of the control main board, and the light sensitive elements 6 also include a driving element. The driving element is controlled by the control main board, and the output end is connected to the movable opening end of the shutter of the solar cell 1 and the movable opening end of the lifting structure through the power of the driving element.

[0033] When the light intensity begins to change, the solar cell 1 rotates along the guide bearing, always facing the direction of greater light intensity.

[0034] Also included is a control host, which includes a host housing and a control mainboard and a power supply arranged inside the host housing;

[0035] The power supply is used to supply power to the driving components, the control host is connected to the mains power, and the control main board is used to receive the light intensity signal of the photosensitive component;

[0036] When the control motherboard finds that the light intensity is the highest at a certain angle, it issues a command to control the driving element to drive the guide bearing, thereby controlling the perovskite solar cell to turn to the angle with the highest light intensity.

[0037] The display screen box 4 includes an integrally formed die-cast aluminum frame 5 and an aluminum bottom shell. The outer layer of the die-cast aluminum frame 5 is coated with moisture-proof, dust-proof and corrosion-resistant three-proof paint.

[0038] The display unit includes a die-cast aluminum bottom shell, a light board and a dual-voltage low-voltage power supply system.

[0039] The die-cast aluminum bottom shell adopts a multi-fold and multi-groove design to increase the heat dissipation area.

[0040] The lamp board includes common cathode lamp beads, a lamp bead driving module and a PCB board.

[0041] The heat inside the display screen can be transferred outward through the die-cast aluminum frame 5 and the die-cast aluminum bottom shell, thereby improving the heat dissipation efficiency and reducing the space requirement for the display screen installation. In particular, the back of the display screen can greatly reduce the required reserved space and reduce the installation cost.

[0042] The solar cell 1 adopts a perovskite solar cell, the guide bearing 2 is installed at the bottom of the solar panel, the support rod 3 is connected to the display screen box 4, and the guide bearing 2 is placed on the top of the support rod 3.

Therefore, the twelve display units can be combined together to play a complete display screen. Of course, they can also play their own display screens separately and switch the playback according to the background.

[0045] Compared with existing technologies, this new outdoor energy-saving bare cooling screen has the following characteristics:

[0046] First, when installed on the exterior wall of a building, there is no need to reserve space for air conditioning, fans, etc. for heat dissipation, which reduces the load-bearing capacity of the building's exterior wall;

[0047] Second, when the light intensity exceeds the set value, the solar panel will continue to move toward the side of the sunlight, using the solar panel to generate photovoltaic power to supplement the power consumption of the display, making the display more energy-efficient.

[0048] Third, a new type of perovskite solar cell is used. Compared with conventional silicon-based solar cells, this cell has a high absorption coefficient and can achieve efficient light absorption at a thinner thickness; the preparation process is relatively simple, which greatly reduces the cost.

[0049] The spectral response range of perovskite materials is wide, and the absorption of light of different wavelengths can be achieved by adjusting the material composition, and it has a good response in the ultraviolet-visible light region.
