AI Technical Summary
Technical Problem
Conventional vehicle floodlights are large in size, inefficient in light utilization, and lack the ability to project symbols indicating vehicle movements, posing safety risks.
Method used
An intelligent vehicle light projecting device with multiple laser light sources, 2D mirrors, focusing lenses, a reflective phosphor plate, and a narrow-band blue light reflector, which dynamically reflects and mixes laser beams to project symbols and improve light efficiency.
Benefits of technology
The device reduces floodlight size, enhances light efficiency, and projects symbols to enhance traffic safety by indicating vehicle movements.

Abstract
To reduce the size of a projection-type vehicle lamp and to improve light efficiency.SOLUTION: The lamp comprises multiple laser light sources, multiple two-dimensional (2D) mirrors, multiple condenser lenses, a reflective phosphor plate, a narrow-band blue-light reflecting mirror, and a lens set. The multiple 2D mirrors are respectively disposed on the paths of multiple laser beams emitted from the multiple laser light sources, and the laser beams are dynamically reflected by the respective multiple 2D mirrors. The reflective phosphor plate includes a phosphor layer and a reflective layer. The narrow-band blue-light reflecting mirror is disposed between the multiple condenser lenses and the reflective phosphor plate, and has a reflective band and a transmission band. The condensed laser beams are reflected by the reflective band of the narrow-band blue-light reflecting mirror and are incident on the reflective phosphor plate. The laser beams excite the phosphor layer to generate mixed white light, which is reflected by the reflective layer of the reflective phosphor plate and is emitted externally through the transmission band of the narrow-band blue-light reflecting mirror.SELECTED DRAWING: Figure 1
