The lamps used in each venue are becoming more and more subdivided and differentiated, and the adaptability to specific lighting venues is more prominent. Among them, for special lighting with high-grade waterproof requirements for indoor and outdoor curved surfaces, it is an important field in the lighting subdivision market. However, at present, for the lighting of indoor and outdoor curved surfaces, conventional flexible light strips with a size (width) less than 50MM are mainly used, and the specifications exceeding 50MM are less.
[0003] The main reason is that as the product size design increases, the corresponding product drive power is also greater, and a better heat dissipation structure supporting is required for high-power products to be realized; and for a high-grade waterproof structure, the better the outer skin protection, the worse the heat dissipation effect; that is, the design concepts of high-power and high-waterproof light strip products are in conflict with each other. To solve the above problems, a large-size waterproof flexible light strip with a braided copper and blind hole heat dissipation structure is provided. Content of the Utility Model
