Document Type and Number:
WIPO Patent Application WO/2019/214217
Kind Code:
A1
Abstract:
A light source module (100) and a vehicle headlight (1100). The light source module (100) comprises a light source (101), a reflecting device (102), and a lens (103). The light source (101) is provided in a space surrounded by the reflecting device (102), and a light emitting surface of the light source (101) faces a reflecting surface (102a) of the reflecting device (102). The reflecting surface (102a) is for reflecting light output from the light source (101) and guiding the light to a light exit port (104) of the reflecting device (102). The lens (103) is provided opposite the light exit port (104) of the reflecting device (102), and an incident light focus (F1) of the lens (103) is provided on a side of the lens (103) near to the reflecting device (102). A reflected light focus (F2) of a second reflecting segment (107) of the reflecting device (102) does not coincide with the incident light focus (F1) of the lens (103). The invention increases an expansion angle of light output by the light source module (100).
