[0002] As an indispensable part of modern cars, automotive lamps play a role far beyond the traditional scope of lighting and signal indication. They are not only key equipment to ensure driving safety at night or in low light conditions, but also an important medium for vehicles to communicate with the outside world, carrying the function of information transmission, such as turn indicators, brake warnings, etc. At the same time, the design of automotive lamps has also become an important embodiment of automotive aesthetics, which can significantly affect the overall appearance and style of the vehicle and is one of the key elements to show the design concept and cultural heritage of the car brand.

[0003] As a lighting device, lamps generally need to use a light source + reflective bowl + decorative panel to form a three-dimensional lighting effect. Although this lighting method can meet basic lighting needs, it may be relatively ordinary in terms of lighting effect and user experience, and it is difficult to fully demonstrate the competitiveness of the product. Moreover, once the shape changes, its supporting devices also need to be redeveloped, which is inefficient and wasteful. Summary of the invention

A plurality of LED particles with a spacing of 13 mm are evenly arranged on the LED light source plate 3. A plurality of single optical convex mirrors with a 60° parabola design are arranged on the blue light diffuser plate 2. The single optical convex mirrors correspond to the LED particles one by one.
