Abstract: A first laser module generates a first light beam along a first light path. A second laser module generates a second light beam along a second light path. A light-guiding module reflects the first light beam to generate a first reflected light beam along a third light path and reflects the second light beam to generate a second reflected light beam along a fourth light path. A wavelength conversion layer of the wavelength conversion device is stimulated by the first reflected light beam to generate a stimulated light beam against the first reflected light beam. The light-guiding module directs the stimulated light beam to the fourth light path. A light rod integrates the stimulated light beam and the second reflected light beam to generate an integrated light beam.

Abstract: A multi-stage lens actuating module includes a housing with a cavity, a lens holder disposed in the cavity for containing a lens component, an elastic piece disposed between the lens holder and the housing, a flange protruding from a side of the lens holder, and a raised bar protruding from a side of the elastic piece. The flange is contact with the raised bar to determine a stroke of the lens holder.
