Abstract
An optical assembly that is adapted to be located at a light path of light emitted from at least one light source and spaced apart from the at least one light source by a distance is provided. The optical assembly includes a wavelength converting device, which is a spatial structure, and a reflector. The reflector covers a portion of the wavelength converting device and exposes at least a portion of a region of at least one surface of the wavelength converting device. The light emitted from the at least one light source enters or leaves the wavelength converting device from at least the portion of area which is not covered by the reflector. An optical module including the light source and the optical assembly is further provided.
