Figure 1A illustrates the schematic perspective view of the Wavelength converter 100 of first embodiment of the invention.Figure
1B illustrates the profile of the fluorescence colour wheel 104 of the Wavelength converter 100 of Figure 1A, and its profile position is such as
Shown in the line segment B-B ' of Figure 1A.Wavelength converter 100 comprises actuating element 102 and fluorescence colour wheel 104.
Fluorescence colour wheel 104 comprises the first optical unit 110, the second optical unit 120 and clutch member 140.Cause
Dynamic element 102 passes through fluorescence colour wheel 104, and the first optical unit 110 and second of fluorescence colour wheel 104
Optical unit 120 is connected to actuating element 102.Additionally, the first optical unit 110 and the second optics list
It is fixing that the relative position relation of unit 120 can pass through clutch member 140.In present embodiment, clutch member
140 is circular annular form thing, but is not limited.Clutch member 140 can arrange and activate unit to be surrounded on
The rotary shaft of part 102, and (ascend the throne positioned at the both sides of the first optical unit 110 and the second optical unit 120
In the lower surface of the first optical unit 110 and the upper surface of the second optical unit 120), by the first optics
Unit 110 and the second optical unit 120 clamping are in wherein.
First optical unit 110 comprises substrate 112 and optical layers 114, and wherein optical layers 114 are arranged at
On substrate 112, and optical layers 114 can be the dielectric film being formed by multiple structure.Second optics list
Unit 120 is stacked and placed in optical layers 114, and wherein optical layers 114 are derived from the second optics list in order at least reflection
The light beam of unit 120.Second optical unit 120 comprises to penetrate substrate 122 and fluorescence coating 124, wherein glimmering
Photosphere 124 is arranged at and penetrates on substrate 122.Additionally, in present embodiment, fluorescence coating 124 is located at and wears
Thoroughly between substrate 122 and optical layers 114.
First optical unit 110 can be formed on substrate 112 by by optical layers 114 plating, the
Two optical units 120 can be by by fluorescence coating 124 plating or coat to penetrate on substrate 122 and formed.
In other words, in the configuration of fluorescence colour wheel 104, the first optical unit 110 and the second optical unit 120
First can be formed respectively, then again the first optical unit 110 is stacked with the second optical unit 120, and
Fixing with clutch member 140.Because the first optical unit 110 and the second optical unit 120 are through folder
The clamping effect that closing element 140 is provided fixes, therefore, the first optical unit 110 and the second optics list
At least a portion on the surface toward each other of unit 120 can be directly connected to or directly contact.In other words, in
Under this configuration, between the first optical unit 110 and the second optical unit 120, at least there is air dielectric layer
130.

For example, optical layers 114 in the refractive index at incident interface be the reflecting spectrum of 1 (such as air) and optical layers
114 reflecting spectrum when refractive index at incident interface is more than 1 are different.Additionally, when optical layers 114
When the wavelength band of incident illumination falls within the wavelength band of visible ray, optical layers 114 are in the folding at incident interface
Penetrate the reflection efficiency that rate is 1 (such as air) and be more than the refractive index in incident interface for the optical layers 114 more than 1
When reflection efficiency.And when the light beam that the second optical unit 120 of wide-angle is launched encounters air layer
When 130, the light beam of this wide-angle can reduce, because there is total reflection, the probability touching optical layers 114.
Furthermore, if the presence of no air layer 130, the second optical unit 120 of wide-angle is launched
Light beam will be reflected by optical layers 114.Because the optical layers 114 being made up of dielectric film are for wide-angle
Design on light beam is quite difficult, and the reflectance of its wide-angle can be less than its low-angle reflectance, therefore
Cause the light of wide-angle can be absorbed by substrate 112 and reduce the light extraction efficiency of fluorescence colour wheel 104.
It is the same as those described above, under the configuration of present embodiment, the first optical unit 110 and the second optical unit
At least there is air dielectric layer 130 between 120.Still further, this air dielectric layer 130 is in
Between fluorescence coating 124 and optical layers 114.In other words, due to the medium positioned at optical layers 114 surface extremely
It is air dielectric less, optical layers 114 can have higher reflection to the light beam from the second optical unit 120
Efficiency.
