Advertising lamp box capable of being automatically controlled to carry out projection based on human body detection

Abstract

The invention discloses an advertising lamp box capable of being automatically controlled to carry out projection based on human body detection. The lamp box comprises a lamp box body and further comprises a projection mechanism, an infrared sensor, a converter, a control circuit, a light source driving circuit, a projection lamp, a motor driving circuit and a stepping motor. The infrared sensor is used for detecting a human body to form an induction signal, the converter is used for converting the induction signal into a digital signal, the control circuit is used for analyzing and obtaining the angle value of the position, where the human body is located, relative to the lamp box body, and generating a motor driving signal and a light source driving signal which drive the stepping motor to rotate; the light source driving circuit drives the light source of the projection lamp to carry out light beam projection; the motor drives the circuit to control rotation of the stepping motor; the stepping motor enables a shell of the projection lamp to rotate to the corresponding angle through a connecting part, and a projection light beam falls at the position of the human body. According to the advertising lamp box, the dynamic advertising mode and the static advertising mode are combined, and the lamp box has the strong visual impact.

Description

technical field [0001] The invention relates to an advertising light box, in particular to an advertising light box that automatically controls projection based on human body detection, and belongs to the technical field of advertising lamps. Background technique [0002] In the lamps, people introduce advertisements into the light box, thus forming an advertising light box. 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 of the unit area of ​​the advertisement. All kinds of chara...

AI Technical Summary

Problems solved by technology

However, it still cannot detect and provide auxiliary projection light irradiation according to the position of the human body, and static lighting cannot quickly cause people's visual impact

[0006] Therefore, the existing advertising light boxes can only be illuminated near the light box, and the human body at a far position relative to the box cannot be irradiated with light, and cannot sense the position of the human body in time to provide projection light auxiliary lighting. To achieve static advertising effect, the visual impact effect is poor, and it cannot be well combined with dynamic advertising effect
