Optical module
An optical module including a reflecting component, a plurality of first light sources and a wavelength conversion body is provided. The reflecting component has a main axis and a focal point located on the main axis. The first light sources are located at one side of the reflecting component and each of the first light sources emits a first light parallel to the main axis towards the reflecting component. The wavelength conversion body is disposed on the focal point, wherein the first lights are reflected to the focal point via the reflecting component and a part of the first lights are converted to a second light via the wavelength conversion body. The second light and another part of the first lights are projected to the reflecting component and form a light beam parallel to the main axis via reflection by the reflecting component.

a first reflecting component having a main axis and a first focal point located on the main axis;
a second reflecting component configured opposite to the first reflecting component, wherein the second reflecting component has a second focal point and the second focal point and the first focal point are located on a common point;
a plurality of first light sources located at one side of the second reflecting component, each of the first light sources emitting a first light parallel to the main axis towards the second reflecting component;
a wavelength conversion body disposed on the common point, wherein the first lights parallel to the main axis are reflected to the wavelength conversion body disposed on the common point via the second reflecting component and a part of the first lights are converted into a second light via the wavelength conversion body, the second light and another part of the first lights are projected to the first reflecting component and forming a first light beam parallel to the main axis via reflection by the first reflecting component; and
a second light source located on the common point, wherein the wavelength conversion body is configured on the second light source, and the second light source comprises a laser diode or a light-emitting diode, wherein the second light source comprises a III-V molecular epitaxy structure, wherein the second light source emits a light through the wavelength conversion body and is projected to the first reflecting component and forming a second light beam parallel to the main axis via reflection by the first reflecting component,
