    Abstract: A light source device includes a lens and a light source disposed under the lens. The lens has a light-emitting top surface and a bottom surface opposite to the light-emitting top surface. The bottom surface concaves towards the light-emitting top surface to form a hole and has a gouge surrounding the hole with an inclination towards the edge of the hole. The hole is formed from the surrounding of a first inner wall surface and a second inner wall surface. The light source is disposed below the bottom surface and corresponds to the hole.
