Intelligent solar light emitting diode (LED) advertising billboard

Abstract

The invention relates to an intelligent solar light emitting diode (LED) advertising billboard, which relates to an advertising board and a propaganda display board, and the intelligent solar LED advertising billboard comprises an LED screen, a framework and a power supply, and the intelligent solar LED advertising billboard is characterized in that a control circuit of the LED advertising billboard is connected with a photosensitive controller, and a power supply circuit of the LED advertising billboard is connected with a solar power supply system. The photosensitive controller is installed on a shell part of the LED advertising billboard and connected with a control signal input end of a micro control unit (MCU) controller, the framework of the LED advertising billboard is of a hollow structure, and the LED screen is a lightproof flat panel and consists of a plurality of LED modules. Due to the adoption of the intelligent solar LED advertising billboard, the brightness of the LED screen can be automatically adjusted, so that the LED advertising billboard is more striking, and a better advertising effect can be realized. A solar panel not only has the advantages of energy conservation and environmental protection, but also can prevent the sunshine and the rain, so that the fault rate of the LED advertising billboard is reduced, the service life is prolonged, and the application effect is good.

Description

technical field [0001] The invention relates to an LED advertising board, in particular to an intelligent solar LED advertising board with brightness intelligent control. Background technique [0002] Advertising billboards are an outdoor media that transmits advertising information and promotional content. In the past, the screens of billboards were usually inkjet and printed, which lacked dynamic effects and the publicity effect was not ideal. [0003] In recent years, with the rapid development of LED technology, using LED as a backlight source is more energy-saving. Lamp, the power consumption of the same power of LED is only a quarter of it. LED light-emitting diode, the abbreviation of Light Emitting Diode in English, is a solid-state semiconductor device that can directly convert electrical energy into light energy. [0004] The LED advertising billboard using LED light-emitting diodes integrates optoelectronic technology, microelectronic technology, computer techno...

Problems solved by technology

[0005] However, because the luminous brightness of LED advertising billboards remains basically constant, it cannot be adjusted appropriately according to the intensity of the surrounding light, and under the strong light such as the sun, the words on the billboards reflect light, making it sometimes difficult for people to see clearly. The content on the advertising billboard not only wastes power resources, but also affects the advertising effect
