Classification: CPC F  G | IPC F  G

Claim 0:
1. A light source module comprising:
a first light-emitting unit configured to emit a first color light;
a second light-emitting unit configured to emit a second color light, wherein the first color light and the second color light have different wavelength ranges respectively;
a first dichroic mirror configured to allow the first color light to transmit through and having a passing area, wherein the passing area is configured to allow the second color light to pass through; and
a wavelength conversion unit comprising a substrate and a phosphor layer disposed on the substrate and a transmissive portion, wherein the phosphor layer is configured to convert a portion of the first color light transmitting through the first dichroic mirror into a third color light, and is configured to reflect and scatter the second color light passing through the passing area, and the transmissive portion is configured to transmit another portion of the first color light transmitting through the first dichroic mirror,
wherein the first dichroic mirror is configured to reflect the second color light reflected by the wavelength conversion unit and the third color light and transmit the first color light such that the first color, second color and third color lights are colinearly directed away from the first dichroic mirror.
