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.

Claims (34)

1. 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.

2. The optical module according to claim 1 , wherein the adjustable reflector adjusts in a continuous manner.

3. The optical module according to claim 1 , wherein the adjustable reflector adjusts in a step-by-step manner.

4. The optical module according to claim 1 , further comprising:

a lens set, and the wavelength conversion set being disposed between the adjustable reflector and the lens set.

5. The optical module according to claim 4 , wherein the wavelength conversion set is disposed on a focal point of the lens set.

6. The optical module according to claim 1 , wherein the light source is a laser light source.

7. The optical module according to claim 1 , wherein the through-hole is completely filled by the first wavelength conversion member and the second wavelength conversion member.

8. An optical module, comprising:

an adjustable light source adaptable to move along an axis between a first position and a second position;

a reflector disposed in a light path of light emitted by the adjustable light source; and

a wavelength conversion set comprising a first wavelength conversion member and a second wavelength conversion member surrounding the first 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 light source is at the first position, the light emitted by the adjustable light source is reflected to only the first wavelength conversion member by the reflector,

when the adjustable light source is at the second position, the light emitted by the adjustable light source is concurrently reflected to both the first wavelength conversion member and the second wavelength conversion member by the reflector.

9. The optical module according to claim 8 , wherein the adjustable light source moves in a continuous manner.

10. The optical module according to claim 8 , wherein the adjustable light source moves in a step-by-step manner.

11. The optical module according to claim 8 , further comprising:

a lens set, and the wavelength conversion set being disposed between the reflector and the lens set.

12. The optical module according to claim 11 , wherein the wavelength conversion set is disposed on a focal point of the lens set.

13. The optical module according to claim 8 , wherein the light source is a laser light source.

14. The optical module according to claim 8 , wherein the through-hole is completely filled by the first wavelength conversion member and the second wavelength conversion member.

15. 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 conformally in the through-hole of the reflective cover, and the first wavelength conversion member and the second wavelength conversion member respectively contact 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 second position, the light emitted by the light source is reflected to the second wavelength conversion ember by the adjustable reflector.
