360? Full coverage without shadow LED desk lamp available [Full text]

**Technology Dynamics** Energy-saving lamps equipped with three LED flat-panel lights offer more than just efficient illumination—they provide 360° full coverage with no shadows, while consuming only one-third the power of traditional desk lamps. Recently, a team of students from the Environmental College at Qingdao Technological University, including Yang Fengguang, successfully obtained a national utility model patent for their innovative 360° shadowless LED lamp design. The basic structure of this advanced lighting system includes a lamp holder, a bracket, and a lamp fan. What sets it apart is the use of three LED flat-panel light fans instead of the conventional single-unit design. These three fans can be arranged in an outward triangular prism shape, enabling full 360° illumination regardless of the angle. This makes the lamp ideal for studying, reading, and office work, effectively replacing the function of three regular desk lamps. Not only does it use the same amount of energy as a single desk lamp, but it also provides better lighting quality, reduces eye strain, and eliminates shadows. Moreover, the bracket and the base of the three light fans are connected by a hinge, allowing the lamp to fold and adjust freely around the central axis. Users can customize the angle between the horizontal planes of the light fans based on personal preference or usage habits. The bracket itself is made of two parts: an upper and a lower bracket, both of the same length. The upper bracket can be inserted into the lower one, and the two are connected via a hinge, allowing the entire structure to fold into a "Z" shape. This folding mechanism significantly reduces the overall size when not in use, making it more convenient for storage and transport. This innovation not only enhances user experience but also represents a step forward in energy-efficient and ergonomic lighting solutions. With its unique design and practical benefits, the 360° shadowless LED lamp has the potential to become a popular choice for students, professionals, and anyone seeking better lighting at home or in the office.
