Problems solved by technology

However, using a laser as an excitation light source has the problem that the high power density of the excitation light will easily cause the conversion efficiency of the wavelength conversion element to decrease.
At the same time, in order to avoid the glare problem and realize the lighting of curves, adaptive laser headlights have attracted more and more attention. The structure contains moving parts, and the structure and control are more complicated

Abstract

The invention provides a light source device and an automobile headlamp, and relates to the field of photoelectric technologies. The light source device comprises lasers, a side-light-emitting opticalfiber array plate, a wavelength conversion element and a control element, wherein the control element is used for adjusting opening and/or closing of the corresponding laser. By means of the light source device, the problem that the conversion efficiency of the wavelength conversion element is reduced easily due to the excessively high excitation light power density when laser light is used as anexcitation light source can be avoided, and meanwhile, the light distribution adjustment function of illumination of the headlamp is realized.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a light source device and an automobile headlamp. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are set forth in the claims and detailed description. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The use of laser diodes for white light illumination is suitable for special lighting such as laser car lights and other fields. At present, the commonly used laser car headlight solution is laser fluorescent solution: blue laser is used as light source to excite yellow fluorescent material, and the converted yellow light and unconverted blue light are mixed to obtain white light. However, using a laser as an excitation light source has the problem that the high power density of the excitation light will easily cause the conversion efficiency o...
