Rotate.The a series of first ribs along the arrangement of wavelength convert disk peripheral direction are included on wavelength convert rotating disk 101
Sheet 103, as shown in Figure 1B, the trend of at least a part of which part the first fin 103 is the front view of the first fin
Along the radial direction of wavelength convert rotating disk, for the generation when wavelength convert rotating disk rotates radially to
The air-flow (representing with arrow 141a in figs. 1 a and 1b) of outer outflow.When wavelength convert rotating disk 101 is by horse
When reaching 105 drives rotation, the adjacent air between the first fin 103 can be due to centrifugal force along first
The trend of fin, to the peripheral outflow of wavelength convert rotating disk, turns simultaneously because negative pressure has the first fin near wavelength
The air of the one end changing center of turntable flows between the first fin.This part flows the air-flow between the first fin
Heat produced by Wavelength converter can be taken away along air current flow direction, simultaneously from wavelength convert rotating disk
The peripheral air-flow flowed out can be by warm added by wavelength convert rotating disk and the first fin.
In the present embodiment, the first fin is centripetal direction, but is not likely to be the most centripetal in actual application
(shown in such as Fig. 1 E), or may be bending (shown in such as Fig. 1 F) or other shape, this
Can be designed according to existing method.What deserves to be explained is, in the present invention, walking of the first fin
To being the radial direction along wavelength convert rotating disk, refer to one end of the first fin in wavelength convert rotating disk
The distance of the heart to the distance of wavelength convert center of turntable, thus can be implemented in wavelength convert less than its other end
The purpose of the air-flow radially flowed outwardly is produced when rotating disk rotates.Air-flow is radially to outflow herein
Go out to be also not limited to flow out along centrifugal direction, such as the air-flow 141a in Fig. 1 E and 1F, as long as turning from wavelength

Again flow between the first fin.In the present embodiment, the second fin top view is as shown in Figure 1 C.Join simultaneously
Examine Figure 1A and Fig. 1 C it can be seen that heated air-flow 141a enters into the air channel that the second fin is formed
After, first (the lower direction in Figure 1A) can be guided downwards to flow, the most again to direction, the center of circle by this air channel
Bending, the air channel formed finally along second fin (as shown in Figure 1 C) of arranged radially is to center of circle side
To flowing, ultimately form gas flow loop and flow again between the first fin.In this process, air-flow 141b
Can transfer heat to the second fin 123 and shell 121, the temperature of air-flow can be due to the biography of heat simultaneously
Go out and reduce.Therefore (first rib is entered into when this air-flow 141b is again introduced into next circulation of air flow
Time between sheet), it has had changed into cold air, thus can continue when forming air-flow 141a to absorb ripple
Long conversion rotating disk and the heat of the first fin.
In sum, utilize rotating and the air-flow that formed of the first fin of wavelength convert rotating disk, and utilize the
The air channel that one fin, the second fin are formed guides formation gas flow loop to this air-flow, it is possible to make this gas
The heat of wavelength convert rotating disk is effectively delivered on shell by stream.So achieving use shell seal wavelength
While conversion colour wheel, heat effectively can be dispersed on shell again, it is ensured that wavelength conversion efficiency and horse
The service life reached.
As shown in Figure 1A, wavelength convert rotating disk 101 includes wavelength conversion layer 102.Wherein, shell
121 include the first optical transmission window 125 for receiving exciting light 161, and this first optical transmission window is to exciting light
It is transmissive to play the most again the effect closing wavelength convert rotating disk.The most in the present embodiment, first is saturating
Light window is a convex lens 125, and it is transmissive to and focused activating light 161 is on wavelength conversion layer 102,
It also is able to play the effect closing wavelength convert rotating disk 101 simultaneously.In actual applications, the first optical transmission window
Can also be transparent glass sheet, or other printing opacity components and parts, the most do not limit.
The top view of wavelength conversion layer 102 is as shown in figure ip, it is seen that wavelength conversion layer 102 depends on exactly
One annular coating of wavelength convert rotating disk.With reference to Figure 1A, when exciting light 161 is through the first optical transmission window
125 when being incident in wavelength conversion layer, and along with wavelength convert rotating disk rotates, each of wavelength conversion layer is excited
Point the most only can be excited in the moment of the light path turning to exciting light 161 and generate heat, and begins to fall after turning round
Temperature, until next cycle is again luminous after passing again to exciting light light path, the mode of excitation of this pulsed makes
The temperature obtaining wavelength conversion layer will not be too high, it is ensured that luminous efficiency.As can be seen here, the ingenious part of the present invention
Also residing in, motor 105 drives wavelength convert rotating disk 101 to rotate can reach two effects simultaneously: make wavelength
Conversion layer works in pulse mode to ensure its luminous efficiency, also creates simultaneously and flows in the first fin and second
Air-flow on fin is to realize heat exchange.
In the present embodiment, wavelength conversion layer 102 is a uniform annular, and in actual applications, also

In have specific application.
Another of the Wavelength converter of the present invention implements such as Fig. 2 A.With the embodiment shown in Figure 1A not
With, the second fin 223 on shell 221 inwall of the Wavelength converter of the present embodiment more simplifies,
Fig. 2 B is the arrangement front view of the second fin.Specifically, with reference to Fig. 2 A and 2B, the second fin 223
Including the first boot segment 223, this first boot segment, is used for away from the one end in the center of circle near the first fin 203
Receive the air-flow produced when wavelength convert rotating disk rotates.First boot segment of the second adjacent fin 223 is formed
First air channel, this first air channel guides the air-flow flowed into turn to towards the first fin near the one end in the center of circle, and shape
Become air-flow 241a.After this air-flow flows out the second fin, meeting is shape due to the first fin rotation produced negative pressure
Become air-flow 241b, thus be inhaled between the first fin, form gas flow loop.
The present embodiment, compared with the embodiment shown in Figure 1A, has got rid of the second fin near air-flow 241b,
Such it is advantageous in that weight saving, but problem is air-flow 241 and the heat exchange degree of shell reduces,
It is more slightly higher that air-flow 241b blows into the temperature of the first fin situation than Figure 1A.
Another embodiment of the Wavelength converter of the present invention is as shown in Figure 3.With Figure 1A illustrated embodiment not
With, the second fin 323 of shell 321 inwall includes the second boot segment 323, the one of the second boot segment
Close first fin of end is close to the one end in the center of circle, for effluent stream 341b to first fin 303 to be formed
Gas flow loop.Second boot segment of the second adjacent fin forms the second air channel, and this second air channel is by wavelength convert
The air-flow 341a produced when rotating disk rotates is along radial direction the connecing to the first fin 303 of wavelength convert rotating disk
The one end in the nearly center of circle guides thus forms air-flow 341b.
In the present embodiment, shell 321 includes the 321a that caves in, for preferably guiding air-flow 341a to flow into the
Two boot segments 323.Even if the 321a it practice, do not cave in, owing to the existence air-flow 341a of negative pressure also can
Most inflow the second boot segment 323, and the 231a that caves in improves the throughput flowing into the second boot segment.
In conjunction with Figure 1A, Fig. 2 A and Fig. 3 it can be seen that the second fin in actually Figure 1A is equivalent to
The second fin in Fig. 2 A and the combination of the second fin in Fig. 3, i.e. the second boot segment 323 in Fig. 3
May be used for receiving the air-flow flowed out in the first boot segment 223 in Fig. 2 A, the most just constitute and scheme

The first fin 403 on wavelength convert rotating disk 401 shown in Fig. 4 B serves the effect forming air-flow equally,
But except for the difference that also include an annular transparent area 401a on wavelength convert colour wheel；Corresponding, shell
The second fin 423 on 421 inwalls serves guiding gas equally and flows to the effect near the center of circle, but different
It is also to include the second optical transmission window 427.So, when wavelength convert rotating disk rotates, annular transparent area 401a
Periodically through the light path of exciting light 461, this annular transparent area of now exciting light transmission transmitting case
Second optical transmission window 427 outgoing.In this present embodiment, the first fin 403 and the second fin 423 are not
Circumference is symmetrical, but cover only part-circular periphery, namely only effectively carries out in part-circular periphery region
Heat exchange；Experiment proves that this situation can also realize heat exchange efficiently, can't produce radiating effect too
