Title:
LIGHT SOURCE SYSTEM, AND AUTOMOBILE HEADLAMP
Document Type and Number:
WIPO Patent Application WO/2019/085252
Kind Code:
A1
Abstract:
A light source system (1) and an automobile headlamp. The light source system comprises an excitation light source (11), a light-emitting device (12) and a control device (13). The excitation light source (11) emits excitation light. The light-emitting device (12) comprises multiple light-emitting units (121, 121a-121d), each of the light-emitting units (121, 121a-121d) switching between a first position and a second position according to the control of the control device (13), and receiving the excitation light and generating excited light at least when at the first position. The control device (13) is used for controlling, according to a pattern needing to be projected in front of the headlamp of the automobile, each of the light-emitting units (121, 121a-121d) so same is respectively located at the first position or the second position, so as to form a desired pattern in front of the headlamp of the automobile, wherein, when at the first position, the excited light generated by each of the light-emitting units (121, 121a-121d) enters a first path (L1) and emerges in front of the headlamp of the automobile; and when at the second position, the excited light generated by each of the light-emitting units (121, 121a-121d) enters a second path (L2) to avoid emerging in front of the headlamp of the automobile, or, each of the light-emitting units (121, 121a-121d) cannot receive the excitation light so as to generate excited light. The application field of a light source system is expanded, and the indication functions of an automobile headlamp are enriched.
