[0002] With the development of technology, the application of LED in automotive lighting is increasing day by day, from the initial application of automotive interior lighting to wider applications such as headlights and combination taillights. In particular, due to its small size, LED can be matched with a variety of shapes and line changes. At the same time, the continuous innovation of mold technology in the lighting industry has led to the emergence of light guides and lamp housings of different shapes, creating a variety of lamp shapes, improving the recognition of lamps, and better matching the overall car design. In the future, with the continuous improvement of technology and market, the application of LED in the field of automotive lighting will be more extensive and comprehensive.

[0003] With the increasing demand for LED automotive lighting, we have continuously analyzed the needs of end customers in the market. We have found that customers have an increasing demand for the appearance of automotive lighting, but the space of the car itself is limited, so the design must not only consider the appearance of the car, but also meet the function of the lamp itself. Traditional automotive lamp structures mostly use multiple single lenses or reflective cups, which leads to excessive space occupation of automotive lamps, limits the diversity of lamps, cannot meet the unique design of lamp shapes, and reduces recognition.

The light passes through the semi-cylindrical diamond-shaped boss on the front, and the principle of the semi-cylindrical convex lens is used to form light convergence and then gather into lines, which reduces the light scattering loss. Many lines converge to form a luminous surface, and the inner and outer bosses are staggered to form a controllable light path. It can not only meet the needs of different LED car lighting, but also adjust the shape of the light guide strip according to the different structures of the car lights, so as to better fit the internal structure of the car lights, reduce space, and solve the problem that traditional lamps occupy a large space and have low adaptability.
