1) Current Market Situation: The current market offers two types of LED display boards: those powered by AC electricity and those using rechargeable batteries. These display boards are less than 10mm thick and can be customized to sizes ranging from A4 to A0, or other special dimensions. They are mainly used in restaurants, hotels, shopping malls, and major public service areas to provide product advertisements and service information. Typically, these LED display boards are used indoors and are installed in fixed locations.
2) Solar-Powered LED Display Board: This type of display board can be used in any location with sunlight, greatly expanding its range of applications. For instance, it can be installed together with a home mailbox to display house numbers and celebratory messages. Around the house, it can provide warnings for pets. When installed around building perimeters, it can display messages such as "Surveillance in Operation" or "No Trespassing." It can also be installed at the entrances of luxury homes or farms to display "Private Property - Keep Out," among other uses.
3) Technical Requirements for Solar-Powered LED Display Boards: These boards typically consist of three main parts: a solar panel, an LED display board, and a controller. They must be waterproof, sun-resistant, and durable in low temperatures. For A4 or A3 size display board, the solar panel can be a 5.5V 500mA laminated monocrystalline silicon panel. The battery should be a low-temperature rechargeable lithium battery with a capacity of over 4000mAh. The controller is crucial for the operation of the solar-powered LED display board. The entire circuit design must use high-resistance components, with a focus on battery protection, including safe charging management, short circuit protection, and low voltage (3.1-3.2V) power-off protection. Another function of the controller is intelligent power management for the LED to ensure that the fully charged lithium battery can power the display for over 7 days.
4) Our Progress: Our company , newsolarzone llc., located at Nashville, TN, has almost completed the development of the solar-powered LED display board. All performance indicators have met the design and usage requirements. We welcome suggestions from colleagues and look forward to working together to achieve success.
