Problems solved by technology

However, the use of solar energy to generate electricity still has the problems of high cost and low conversion efficiency. Therefore, the utilization of solar energy is not very popular.
[0003] In the prior art, people have realized using solar energy to supply power to LED display screens, such as a solar LED display screen disclosed in Chinese patent documents [application number: 201320415582.0; authorized announcement number: CN203366654U], its structure includes vertically arranged LED display screen, frame, solar panel, support module, universal wheel, by using the solar energy collected by the solar panel to supply power to the LED display, saving electric energy; The solar panels can collect more solar energy; however, this structure cannot effectively improve the conversion efficiency of solar energy. If a solar LED display with higher solar conversion efficiency can be designed, it will bring more benefits to people's daily life. come very convenient

Embodiment 1

[0019] Such as figure 1 Shown is a LED display screen powered by solar energy, comprising an LED display screen 1, a solar panel 2, and a support, wherein it also includes a solar automatic tracking module 12, and the LED display screen 1 is installed on the support; the support set On the back of the LED display screen 1; the solar panel 2 is arranged on the top of the LED display screen 1; the solar automatic tracking module 12 is fixedly connected with the support; the solar automatic tracking module 12 includes an azimuth detection circuit 3, an elevation angle Detection circuit 4, west limit switch 5, motor drive circuit 6, azimuth angle transmission mechanism 7, altitude angle transmission mechanism 8.

[0020] Wherein, the support includes a base 9, a vertical support 10, a circular support 11 installed on the top of the vertical support 10; the base 9 is fixedly connected with the vertical support 10; the circular support 11 is flexibly connected with the vertical supp...

Embodiment 2

[0025] On the basis of Example 1, such as figure 2 As shown, the solar automatic tracking module 12 includes an azimuth detection circuit 3, an altitude detection circuit 4, a west limit switch 5, a motor drive circuit 6, an azimuth transmission mechanism 7, and an elevation angle transmission mechanism 8; Circuit 6 can use two DC motors A and B for the adjustment and control of the east-west direction and the north-south direction respectively, and the DC motors A and B can use steering gear with a slow speed and a deceleration mechanism; The deflection is about 47 degrees positive and negative, and the deflection degree in one day is only 15ˊ. The adjustable output speed can be as low as 1~2 rpm, and the whole mechanism runs smoothly; the motor A drives the solar panel 2 to rotate in the east-west direction to achieve the adjustment of solar energy. The purpose of the azimuth angle of the solar panel 2 is to drive the solar panel 2 to rotate in the north-south direction thr...

Embodiment 3

[0027] On the basis of Embodiment 1, the LED display screen powered by solar energy provided by the present invention can be widely used in display signs in some public areas. At the same time, universal wheels can also be added at the bottom of the base 9 to facilitate movement; The circular support 11 and the vertical support 10 can be connected by a rotary connector made of high-strength, light-weight alloy steel, so that the solar panel 2 can be adjusted by the azimuth transmission mechanism 7 or the elevation angle according to the adjustment of the motor drive circuit 6. The transmission mechanism 8 rotates accordingly, thereby improving the conversion efficiency of the solar battery panel 2 and achieving the purpose of saving energy.

Abstract

The invention provides an LED display screen using solar power supply. The LED display screen comprises an LED display screen body, a solar cell panel, a support and a solar automatic tracking module. The solar automatic tracking module comprises an azimuth detection circuit, an elevation angle detection circuit, a western limit switch, a motor driving circuit, an azimuth transmission mechanism and an elevation angle transmission mechanism. The solar automatic tracking module is added, when the solar cell panel is deviated from the sun, the azimuth (elevation angle) detection circuit detects corresponding position information of the sun, the motor driving circuit processes the related position information and then sends the processed information to the azimuth (elevation angle) transmission mechanism, and thus, the solar cell panel is aligned with the sun in the east-west (north-south) direction; when the dust draws near, the solar cell panel triggers the western limit switch when moving towards the west, and a limit switch circuit starts working so that the solar cell panel returns to an initial position; and the LED display screen has good application prospects and high market values.

Description

technical field [0001] The invention belongs to the application field of solar energy technology, and in particular relates to an LED display screen powered by solar energy. Background technique [0002] Solar energy, generally referring to the radiant energy of sunlight, is the energy produced by the fusion of internal hydrogen atoms and releases huge nuclear energy. The radiant energy from the sun, most of the energy needed by human beings comes directly or indirectly from the sun. The use of solar energy has two ways: passive utilization and photoelectric conversion. Solar plants release oxygen and absorb carbon dioxide through photosynthesis, and convert solar energy into chemical energy and store it in plants; solar water heaters for rural households absorb and transform the absorbed solar water heaters For thermal energy; solar cells are used in providing energy for artificial satellites. However, the use of solar energy to generate electricity still has the problems ...
