Fluorescent module and light source system

Abstract

The invention discloses a fluorescent module. The fluorescent module comprises a cavity body, a reflecting wall arranged in a part of the cavity body, and a wavelength conversion layer arranged on a part of the reflecting wall, wherein the cavity body is provided with a light-transmitting port; and the wavelength conversion layer is provided with a preset thickness, exciting light irradiates intothe wavelength conversion layer with the preset thickness through the light-transmitting port to be completely absorbed in the wavelength conversion layer with the preset thickness through a round trip, and converted to be excited light. The invention further provides a light source system comprising the fluorescent module. Because the incident exciting light is completely converted to be the excited light, the light purity of the emitted excited light is greatly increased, and the light-emitting brightness is also increased.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a fluorescent module and a light source system. Background technique [0002] In the existing light source systems that use lasers to excite fluorescent materials to generate received light as light sources, the light emitted by laser light-emitting elements reaches the fluorescent materials through optical components (such as light combining devices, beam shaping devices), and is converted by fluorescent materials to obtain illumination light. However, the conversion efficiency of existing light source systems for converting excitation light into stimulated light is very low. [0003] In order to solve the above problems, the phosphor powder is placed in the cavity, and the laser is used to excite the fluorescence in the cavity to generate excitation light, thereby obtaining high-brightness outgoing light. However, the excitation light in the prior art cannot be fully utilized,...

Problems solved by technology

However, the conversion efficiency of existing light source systems to convert excitation light into stimulated light is very low.

[0003] In order to solve the above problems, the phosphor powder is placed in the cavity, and the laser is used to excite the fluorescence in the cavity to generate excitation light, thereby obtaining high-brightness outgoing light. However, the excitation light in the prior art cannot be fully utilized, resulting in The emitted light usually includes the excitation light and the affected light, so the outgoing light is impure, and the brightness of the final outgoing light is not high due to the low light conversion efficiency
