摘要： A light spreading complex lens through which light is irradiated and transmitted from a rear side toward a front side of the lens is provided. The lens includes a main body that has a predetermined thickness and is formed with an aperture that is penetrated in a vertical direction. A refraction lens part protrudes toward the rear side of the lens from a first surface near to the front side of the lens in the inner surfaces of the aperture.

摘要： A light source module and a vehicle headlamp is provided. The light source module and the vehicle headlamp include a circuit board and first and second light emitting modules that are disposed on the circuit board. The first and second light emitting modules are divided by a partition wall. Each of the first and second light emitting modules includes a blue LED light source and a phosphor that is disposed on the blue LED light source. The phosphor is configured to be activated by the blue LED light source to emit first light and includes a phosphor film that is disposed on an exterior of the first light emitting module and the phosphor film is configured to emit a second light.
