[0002] In the field of home appliance product design, decorative light strips are a common design element that can increase the aesthetics and user experience of the product. However, traditional decorative light strips usually use direct irradiation. Although this method can achieve lighting effects, the light is relatively dazzling and affects the user experience. In order to solve this problem, researchers began to explore new light guide structures, hoping to achieve soft light effects and improve user experience.
