Detailed description of the invention
The structural representation of the first embodiment of the Wavelength converter of the present invention is as shown in Figure 1A.This Wavelength converter
Including wavelength convert rotating disk 101 and motor 105, motor 105 is used for driving wavelength convert rotating disk 101 to rotate.Wavelength convert rotating disk
A series of first fins 103 along the arrangement of wavelength convert disk peripheral direction, the front view of the first fin such as Figure 1B is included on 101
Shown in, the trend of at least a part of which part the first fin 103 is the radial direction along wavelength convert rotating disk, for turning at wavelength
Change when rotating disk rotates and produce the air-flow (representing with arrow 141a in figs. 1 a and 1b) radially flowed outwardly.When wavelength turns
Changing rotating disk 101 when being driven rotation by motor 105, the adjacent air between the first fin 103 can be due to centrifugal force along
The trend of one fin is to the peripheral outflow of wavelength convert rotating disk, simultaneously because negative pressure has the first fin near wavelength convert rotating disk
The air of the one end at center flows between the first fin.This part flows the air-flow between the first fin can be by wavelength convert
Heat produced by device is taken away along air current flow direction, and the air-flow simultaneously flowed out from wavelength convert turntable periphery can be by wavelength
Heat added by conversion rotating disk and the first fin.
In the present embodiment, the first fin is centripetal direction, but actual application is not likely to be the most centripetal (such as
Shown in Fig. 1 E), or may be bending (shown in such as Fig. 1 F) or other shape, this is can be according to existing method
It is designed.What deserves to be explained is, in the present invention, the trend of the first fin is the radial direction along wavelength convert rotating disk
, refer to one end of the first fin distance to wavelength convert center of turntable less than its other end to wavelength convert center of turntable
Distance, thus can be implemented in when wavelength convert rotating disk rotates and produce the purpose of air-flow radially flowed outwardly.
Air-flow radially flows outwardly and is also not limited to flow out along centrifugal direction herein, such as the air-flow 141a in Fig. 1 E and 1F,
Just can achieve the goal as long as flowing outwardly from wavelength convert turntable periphery.Therefore, as long as meeting the first fin of above-mentioned requirements
Just belong to protection scope of the present invention.
The Wavelength converter of the present embodiment also includes shell 121, for being closed within it by wavelength convert rotating disk 101
Portion.The inwall of this shell 121 includes that a series of second fin 123, the second the most adjacent fin form air channel, this air channel
For guiding the air-flow 141a radially outward flowed out from wavelength convert rotating disk 101 at least partially return to the first fin near the center of circle
One end, formed air-flow 141b, to form gas flow loop, again flow between the first fin.In the present embodiment, the second fin
Top view is as shown in Figure 1 C.With reference to Figure 1A and Fig. 1 C it can be seen that heated air-flow 141a enters into the second fin institute
Behind the air channel formed, first (the lower direction in Figure 1A) can be guided downwards to flow by this air channel, curved to direction, the center of circle the most again
Folding, the air channel formed finally along second fin (as shown in Figure 1 C) of arranged radially flows to direction, the center of circle, end form
Gas flow loop is become to 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 reduce due to spreading out of of heat simultaneously.Therefore again enter as this air-flow 141b
When entering next circulation of air flow (when entering between the first fin), it has had changed into cold air, thus can be in shape
Absorbing wavelength conversion rotating disk and the heat of the first fin is continued when becoming air-flow 141a.
In sum, utilize wavelength convert rotating disk rotates the air-flow formed with the first fin, and utilizes first rib
The air channel that sheet, the second fin are formed guides formation gas flow loop to this air-flow, it is possible to make this air-flow effectively by ripple
The heat of long conversion rotating disk is delivered on shell.So while achieving use shell seal wavelength convert colour wheel, again can
Enough heat is effectively dispersed on shell, it is ensured that wavelength conversion efficiency and the service life of motor.
As shown in Figure 1A, wavelength convert rotating disk 101 includes wavelength conversion layer 102.Wherein, shell 121 include for
Receiving the first optical transmission window 125 of exciting light 161, exciting light is transmissive to play again envelope by this first optical transmission window simultaneously
Close the effect of wavelength convert rotating disk.The most in the present embodiment, the first optical transmission 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 reality
In the application of border, the first optical transmission window can also be transparent glass sheet, or other printing opacity components and parts, does not the most 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 wavelength convert exactly and turns
One annular coating of dish.With reference to Figure 1A, when exciting light 161 is incident in wavelength conversion layer through the first optical transmission window 125, with
Wavelength convert rotating disk to rotate, each of wavelength conversion layer is excited a little only can turn to the light path of exciting light 161
Moment is excited and generates heat, and begins to cooling after turning round, until next cycle is sent out after passing again to exciting light light path again
Light, the mode of excitation of this pulsed makes the temperature of 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 resides in, and 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 the second fin
On air-flow to realize heat exchange.
In the present embodiment, wavelength conversion layer 102 is a uniform annular, and in actual applications, it is also possible to edge

Another embodiment of the Wavelength converter of the present invention is as shown in Figure 3.Unlike Figure 1A illustrated embodiment,
Second fin 323 of shell 321 inwall includes the second boot segment 323, and one end of the second boot segment is near the close circle of the first fin
One end of the heart, for effluent stream 341b to first fin 303 to form gas flow loop.Second guiding of the second adjacent fin
Section forms the second air channel, and the air-flow 341a produced when wavelength convert rotating disk is rotated by this second air channel is along wavelength convert rotating disk
Radial direction guides to one end close to the center of circle of the first fin 303 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 second boot segment
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 second in Fig. 2 A
The combination of the second fin in fin and Fig. 3, i.e. what the second boot segment 323 in Fig. 3 may be used for receiving in Fig. 2 A first draws
The air-flow flowed out in the section of leading 223, the most just constitutes the gas flow loop as Figure 1A and heat exchange method.
