Abstract
A semiconductor light source device is provided. The semiconductor light source device includes a light guide, at least one semiconductor light source set and at least one light transformation coupler. The light transformation coupler is disposed between the semiconductor light source set and the light guide for guiding the light emitted from the semiconductor light source set to the light guide. The light transformation coupler has an inclined surface and a curved surface. The inclined surface is a multi-level inclined surface with several slopes.
