1. A light source device, comprising:
a light emitting diode (LED) chip; and a molding lens, which is directly formed on the LED chip, comprising a center of a bottom where the LED chip located at and a light exiting surface formed corresponding to the center; wherein the light exiting surface comprises a concave portion, a first light exiting region surrounding the concave portion and a second light exiting region surrounding the first light exiting region, and the first light exiting region connects between the concave portion and the second light exiting region, wherein the concave portion comprises a first V-shaped valley comprising a first flat surface and a second flat surface connected to each other in a non-coplanar manner, and a vertex angle is formed between the first flat surface and the second flat surface in cross section view, wherein the vertex angle comprises a first vertex angle formed between the first flat surface and a vertical plane, and a second vertex angle formed between the second flat surface and the vertical plane, wherein the concave portion is symmetric corresponding to the center of the bottom, and the degree of the first vertex angle is equal to the degree of the second vertex angle, wherein the concave portion further comprises a second V-shaped valley intersected with the first V-shaped valley. |
