LED light pole display, also called LED light pole screen, is a LED display specially mounted on street light poles. It combines WiFi Internet technology, power carrier Internet of Things technology, sensing technology, etc., and is an important practice in the construction of smart cities. LED light pole displays can go deep into various fields such as urban management, energy saving, security, and convenience, and play different functions according to actual needs.
The working principle of the LED light pole display is to convert electrical signals into light signals, and display images or text by controlling the brightness and color of the LED. It consists of many LEDs, each of which is a semiconductor device that emits light at forward voltage. These LEDs are organized into a matrix or row, and each LED has an independent control circuit that can control the brightness and color of the LED by controlling the switching state of the circuit. When an image or text needs to be displayed, the computer converts the image or text into a digital signal and sends it to the control circuit of the LED display. The control circuit converts the digital signal into a control signal to display the image or text.
LED light pole displays have a variety of application scenarios. For example, it can be used to display traffic signs, remind drivers to obey traffic rules, and switch to display temporary traffic control information in the event of an emergency. In busy commercial districts or densely populated transportation hubs, the advertising capabilities of LED light pole displays are particularly outstanding. In addition, it can also work with cameras on street light poles to display pictures or videos of traffic violations in real time, serving as a warning to vehicles and pedestrians. In urban parks, tourist attractions and other scenes, LED light pole displays can also display environmental monitoring data in real time, such as air quality, temperature and humidity, etc., allowing citizens to understand the current environmental conditions and promote public awareness of environmental protection.
However, LED light pole displays also have some shortcomings, such as low resolution, low contrast, and high after-sales rate. In addition, if it is installed outdoors, in order to achieve rapid heat dissipation, air conditioning and other equipment may need to be installed, which adds additional costs.
