Description

Technical Field

[0001] This utility model relates to the field of LED light control technology, and in particular to a solar LED light control system. Background Technology

[0002] LED (Light Emitting Diode) lights, as an energy-efficient lighting option, are widely used in various scenarios such as municipal lighting, garden decoration, and home lighting. Traditional solar LED lights are mostly used in large outdoor lighting equipment such as municipal street lights and garden lights. They are usually equipped with high-power solar panels and battery packs, enabling all-weather solar charging and meeting the need for stable lighting over long periods. However, these LED lights are relatively large and fixed in their installation, making it inconvenient to disassemble them for indoor charging or to carry a power bank outdoors for charging. Therefore, they are usually not designed with USB (Universal Serial Bus) charging functionality, resulting in lower flexibility. On the other hand, there are also many small LED decorative lights or portable LED lighting lights on the market. They are compact in size and support USB charging, allowing users to charge them anytime via power bank, computer, or adapter. However, they usually do not have solar charging functionality, and their battery life and outdoor adaptability are relatively limited. With the increasing diversification of lighting needs, more and more users hope to have LED lights that support both solar charging and USB charging to meet the needs of different environments and scenarios.
