Title:
LIGHT SOURCE APPARATUS, AND AUTOMOBILE HEADLAMP
Document Type and Number:
WIPO Patent Application WO/2019/218644
Kind Code:
A1
Abstract:
A light source apparatus (1), and an automobile headlamp (5), which relate to the technical field of photoelectricity. The light source apparatus (1) comprises a laser, a side-emitting fiber array substrate (12), a wavelength conversion element (14) and a control element (13), wherein the control element (13) is used for adjusting the turning-on and/or turning-off of the corresponding laser. The light source apparatus (1) can avoid the problem of the conversion efficiency of the wavelength conversion element (14) being easily reduced due to the power density of excitation light being too high when a laser is used as an excitation light source, and can also realize the function of adjusting the light distribution of the illumination of the headlamp (5).
