Abstract
A smart projection vehicle lamp includes laser light sources, two-dimensional MEMS mirrors, focusing lenses, a reflective phosphor plate, a narrow-band blue light reflector, and a lens group. The two-dimensional MEMS mirrors are correspondingly arranged on paths of laser light beams of the laser light sources. The laser light beams are dynamically reflected by the two-dimensional MEMS mirrors. The reflective phosphor plate has a phosphor layer and a reflective layer located on one side of the phosphor layer. The narrow-band blue light reflector is disposed between the focusing lenses and the reflective phosphor plate, and has a reflective band and a transmissive band. The converged laser light beams are reflected by the reflective band and illuminate the reflective phosphor plate. The laser light beams excite the phosphor layer and are mixed into visible light reflected by the reflective layer and passes through the transmissive band to be emitted outward.
