Patent ID: 8545032

Claim:
A light source module, comprising: a first light emitting device, for emitting an exciting beam, wherein the exciting beam is a laser beam; a reflection unit, disposed on a transmission path of the exciting beam; a wavelength conversion unit, disposed on the reflection unit, and located on the transmission path of the exciting beam, wherein the exciting beam is obliquely incident into the wavelength conversion unit along an optical axis of the first light emitting device, and the wavelength conversion unit converts the exciting beam into a first color beam; a second light emitting device, for emitting a second color beam; and a light combination unit, disposed on transmission paths of the first color beam and the second color beam, for combining the first color beam and the second color beam; a dichroic unit, disposed on the transmission path of the exciting beam and located between the first light emitting device and the wavelength conversion unit, wherein the dichroic unit is for transmitting the exciting beam to the wavelength conversion unit, and is for reflecting the first color beam emitted from the wavelength conversion unit to the combination unit.
