  • Publication number: 20250185902
    Abstract: A light source device comprises a first light combination module and at least two light sources. The light source device is configured to be connected with a light guide module. The at least two light sources include a first light source and at least one second light source. The first light combination module includes a first light combination element. The first light combination element is disposed between the light guide module and the first light source and configured to transform a first beam into a first transmitted light, the first beam being related to the first light source. The first light combination element is further configured to generate a first reflected light from at least one second beam emitted by the at least one second light source, and combine the first reflected light and the first transmitted light into a combined light.
