Abstract

An optical module including a light source, an adjustable reflector and a wavelength conversion set is provided. The adjustable reflector is disposed in a light path of light emitted from the light source and adaptable to adjust between a first position and a second position. The wavelength conversion set includes a first wavelength conversion member and a second wavelength conversion member. When the adjustable reflector is at the first position, light emitted from the light source is reflected to the first wavelength conversion member by the adjustable reflector. When the adjustable reflector is at the second position, light emitted from the light source is reflected to the second wavelength conversion member by the adjustable reflector.

Dependent claims

An optical module, comprising:

a light source;
an adjustable reflector disposed in a light path of light emitted by the light source, and adaptable to adjust between a first position and a second position;
and
a wavelength conversion set comprising a first wavelength conversion member and a second wavelength conversion member;
a reflective cover having a through-hole and the wavelength conversion set being disposed in the through-hole of the reflective cover, wherein a total of a width of a surface of the first wavelength conversion member facing towards the adjustable reflector and a width of a surface of the second wavelength conversion member facing towards the adjustable reflector of the wavelength conversion set equals a total width of the through-hole, and the surface of the first wavelength conversion member facing towards the adjustable reflector, the surface of the second wavelength conversion member facing towards the adjustable reflector and a surface of the reflective cover facing towards the adjustable reflector are coplanar, wherein
when the adjustable reflector is at the first position, the light emitted by the light source is reflected to the first wavelength conversion member by the adjustable reflector,
when the adjustable reflector is at the second position, the light emitted by the light source is reflected to the second wavelength conversion member by the adjustable reflector.
