Advertising lamp box based on solar power supply

Abstract

The invention discloses an advertising lamp box based on solar power supply. The advertising lamp box comprises a lamp box body and further comprises a photoelectric conversion mechanism arranged on the lamp box body, a solar power piece, a power storage module, a supporting frame, a photoelectric sensing module, a conversion module, a control module, a motor driving module and a servo motor. The solar power piece is connected with the power storage module, the photoelectric sensing module is used for measuring the angle, incident to the surface of the solar power piece, of sunlight, and obtaining an analog signal; the conversion module is used for converting the analog signal into a digital signal; the control module is used for analyzing the obtained angle value, incident to the piece of the solar power piece, of the sunlight and comparing the angle value with the preset angle value, and when a difference value exists between the obtained angle value and the preset angle value, a driving signal is generated; the motor driving module drives an output shaft of the servo motor to rotate according to the driving signals to enable the supporting frame to deflect. The advertising lamp box has the automatic detection and adjusting functions, and collection of solar energy is achieved better.

Description

technical field [0001] The invention relates to an advertising light box, in particular to an advertising light box powered by solar energy, and belongs to the technical field of advertising lamps. Background technique [0002] Nowadays, with the continuous development of the advertising industry, introducing advertisements into light boxes has become a common way of advertising. Therefore, the advertising light box is widely used. A general advertising light box includes a box body and a light tube control circuit arranged in the box body, and the advertising paper is set in the box body, and the light tube is controlled by the light tube control circuit to illuminate the light box, thereby illuminating the advertising paper, thereby realizing the function of the light box. Advertising role. The lamp control circuit can also control the continuous flickering and staying of the lamp tube, which effectively improves people's visual impact and improves the utilization rate o...

Problems solved by technology

However, it still effectively utilizes the sunlight in the environment, and cannot collect solar energy and make adjustments according to the angle of incident on the mirror surface, so it cannot save energy well

[0006] Therefore, the existing advertising light boxes can only rely on direct current, but cannot make full use of the sunlight in the natural environment, cannot collect and deflect the electric sheet that collects sunlight according to the angle of sunlight incident on the mirror surface, and cannot collect sunlight well , thereby reducing the efficiency of the use of advertising light boxes
