Craft guide for Illuminated sign

External structure
It consists of three parts: monocrystalline silicon solar panel, LED circuit reflective sign board, and power program control box.
working principle
1. The monocrystalline silicon solar panel converts the sun's light energy into electric energy during the day to charge and store the power program control box, and the battery discharges to the LED circuit sign board at night to ensure that the sign board surface glows.
2. The power program control box is equipped with overcharge and overdischarge protection devices, and has a power memory function. When the voltage is insufficient, it can automatically adjust the light-emitting mode to intermittent strobe to save power and ensure longer continuous work.
3. Using the most advanced solar circuit voltage drop technology (the standard drafting unit Nanjing Saikang Transportation Industry Co., Ltd. holds the technology patent), stop powering the LED circuit sign board under the light state, and connect the LED circuit under the dark state The circuit on the sign board is working normally.
Technical performance
1. The special all-aluminum frame trim with thickness of 2mm and width of 35mm, the overall stability of the logo panel and back panel, the regular shape, and the easy disassembly and maintenance of the logo bottom panel.
2. Adopting the most advanced international solid colloid maintenance-free battery, the battery is safe and has no defects such as leakage, corrosion and toxicity. It can continue to be charged after being completely discharged. The battery has a natural service life of 3-5 years and has a high recycling value.
3. Using polysilicon solar panels, the highest conversion efficiency is 17%, and the service life is up to 20 years.
4. The LED light-emitting tube is packaged with the world's most advanced Taiwan Opto Lei chip, with an average brightness of more than 3000cd, long-distance visibility from 1,000 meters, and a service life of more than 100,000 hours.
5. The control main board is separately installed in the power program control box, and the frequency, brightness, working mode, etc. can be adjusted arbitrarily. It is easy to replace and maintain when it is damaged.
