Abstract

The invention provides a light source system and a lighting device comprising the light source system, and the light source system comprises at least one laser, a substrate, a reflecting layer, a wavelength conversion layer and a light guide element; the laser is used for emitting exciting light; the base body is made of a high-thermal-conductivity material, a groove is formed in the base body, and the laser is contained in the side wall of the groove; the reflecting layer covers the groove wall and is used for reflecting the exciting light; the wavelength conversion layer is arranged on a part of the surface of the reflecting layer and is used for performing wavelength conversion on the exciting light to obtain excited light; and the light guide element covers the opening of the groove, and is used for guiding the exciting light and the excited light, so that light source light emitted by the light source system is obtained. The light source solves the heat dissipation problem of thelaser and the wavelength conversion layer.

Description

technical field [0001] The invention relates to the field of light source technology, in particular to a light source system and a lighting device. Background technique [0002] This section is intended to provide a background or context to a detailed description of the invention that is recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, solid-state light sources used in the lighting field use blue lasers plus phosphors to achieve white light output. Blue lasers can work at high drive power densities and produce higher luminous flux. A light source using a blue laser can obtain tens of times higher brightness than an LED. For applications with strict volume and etendue constraints, blue lasers have inherent advantages as light sources. [0004] At present, there are still certain technical problems in the solid-state light source based on the blue laser, such as the heat dissipation problem o...
