In order to address this problem, inventor attempts the body seal of light source to get up, but low effort, and reason is that the shell of light source has multiple parts to be spliced, be difficult to accomplish airtight each other, be therefore difficult to stop that short grained dust enters the light path of light source inner.And, using the material such as adhesive tape, adhesive tape to increase impermeability between multiple parts, the larger proportion of goods damageds can be caused when after-sales service, virtually adding cost.
Finally, inventor have found solution, as described below.
The present invention proposes a kind of optics module, and the structural representation of its first embodiment as shown in Figure 1.This optics module is for receiving laser 111 and guiding it.This optics module comprises optical system, and optical system is made up of, for guiding laser at least one optical element 101.Specifically, in the present embodiment, optical element 101 is collector lens, the laser 111 of incidence can be focused on.Optics module also comprises the first shell 103, and this first shell 103 is assembled by least two the first casing assemblies, for optical system being closed therein.First shell 103 comprises the light inlet cover plate 105 of light inlet 103a and closed light inlet 103a.Wherein, light inlet 103a is for receiving laser 111, and light inlet cover plate 105 can transmission laser 111, and therefore laser 111 can enter into the inside of the first shell 103, and light inlet cover plate 105 also assures that the closure of the first shell 103 simultaneously.In FIG, light inlet cover plate 105 is not closely adjacent to light inlet 103a, and this is the clarity in order to represent in figure, and light inlet cover plate 105 is closely adjacent to light inlet 103a and has reached its effect closed in practice.Identical in figure below, no longer repeat specification.
What deserves to be explained is, in the description of various embodiments of the present invention, repeatedly use " closing ", it represents that the method for use routine is surrounded other object therein, and and can not carry out unobstructed gas or the flowing of liquid between the external world.Such as use two casing assemblies to be assembled into a complete shell other object is closed therein, refer to two casing assemblies and be engaged completely in design, assembled rear surface does not have obvious hole or space.In actual assembled, even if due to factors such as mismachining tolerance, material are rough, make gas or liquid to be infiltrated by assembled seam or ooze out, owing to can not carry out unobstructed circulation between the external world, this complete assembled body is also closed.
Optics module also comprises second housing 104, for by the joint sealing between the first casing assembly therein.Specifically, in the present embodiment, the first shell 103 is closed therein by second housing 104, certain so also just to achieve the first casing assembly between the object of joint sealing in second housing inside.Inner in order to allow laser 111 enter the first shell 103, second housing 104 comprises the light inlet cover plate 106 of light inlet 104a and closed light inlet 104a.Identical reason, like this, laser 111 just can enter in second housing through light inlet 104a, and light inlet cover plate 106 also assures that the closure of second housing 104 simultaneously.
In the present embodiment, also comprise the Wavelength converter 102 being positioned at the first shell 103 inside, for receiving laser 111 and launching Stimulated Light 112.Wavelength converter is exactly wavelength conversion layer 102 in the present embodiment.What laser 111 focused on after collector lens 101 is incident on wavelength conversion layer 102, wavelength conversion layer 102 is excited and is launched Stimulated Light 112, Stimulated Light 112 is collected the outgoing after the light inlet 103a of the first shell and the light inlet 104a of second housing of rear collimation by collector lens 101, then reflects on light-dividing device 107.Light-dividing device 107 is light splitting optical filters, reflects Stimulated Light 112 for transmission laser 111 simultaneously, and such Stimulated Light just can be separated with laser optical path and be able to outgoing.
In the present embodiment, optical system and Wavelength converter are by the first shell seal, and the seam between the first casing assembly is closed by second housing, this is just equivalent to optical system and Wavelength converter has been closed twice, and so dust enters the decline of probability just in several order of magnitude of optical system from the external world.Experiment also proves, the light source manufactured like this, slowly, serviceable life extends greatly in its brightness decay.
In the present embodiment, the first shell and second housing are fixedly linked, and are conducive to shedding of assembling product and heat like this.Preferably, the first shell and second housing work in-process one-body molded.This preferred version is equally applicable to the following examples certainly.
In the embodiment shown in fig. 1, Wavelength converter 102 is positioned at the inside of the first shell, and depends on the inwall of the first shell, and the heat that such Wavelength converter produces can pass to the effect that the first shell has reached heat radiation.In another embodiment, Wavelength converter is then positioned at outside the first shell, and second housing is inner.
As shown in Figure 2, the difference of the embodiment shown in the present embodiment and Fig. 1 is, first shell 203 also comprises Laser output mouth 203b and covers the bright dipping cover plate 208 on Laser output mouth 203b, laser 211 is from Laser output mouth 203b outgoing after collector lens 201 focuses on, and bright dipping cover plate 208 is for closed Laser output mouth transmission laser simultaneously.Wavelength converter 202 is wavelength conversion layers, and it is positioned at the inside of second housing 204, launches Stimulated Light 212 for the laser 211 that receives from the outgoing of Laser output mouth.Same, Stimulated Light 212 is collected by collector lens 201 and through the light inlet outgoing of the first shell and second housing after collimating.The principle of work of the embodiment shown in the present embodiment with Fig. 1 is identical, unlike the position of wavelength conversion layer.Same, in the present embodiment, optical system is enclosed twice by the first shell and second housing, and the probability that dust enters is very low.
In the above two embodiments, the first shell is all complete totally enclosed by second housing, and in fact might not need so.The structural representation of another embodiment of optics module of the present invention as shown in Figure 3A.In the present embodiment, in order to clear expression first shell, depict the first casing assembly 3031 and 3032, first shell 303 assembled by both.
What deserves to be explained is, in other embodiments, if do not draw the first casing assembly especially, do not illustrate there is no the first casing assembly, but there is no need to particularly point out in explanation.In addition in figure 3 a, have obvious space between two the first casing assemblies, this is to represent the special processing conveniently done in figure, and both are closely assembled in practice.
With the embodiment shown in Fig. 1 unlike, in the present embodiment, the first shell 303 is not closed therein by second housing 304 completely, and light inlet and the light inlet cover plate 305 of the first shell are not sealed to second housing inside.Simultaneously, the part enclosure of second housing and the first casing assembly 3031 fits tightly (sticking part is as shown in the dashed circle of light inlet cover plate about 305 both sides in Fig. 3 A), enclose the seam between two the first casing assemblies, namely second housing by the joint sealing between the first casing assembly therein.Like this, because the seam between two the first casing assemblies is closed, dust just has no chance directly to enter into the first enclosure from the external world, and optical system has still been closed twice.
Similar with the embodiment shown in Fig. 3 A, in embodiment shown in Fig. 3 B, the first shell 303 is not also closed therein by second housing 304 completely, the part enclosure of second housing 304 and the first casing assembly 3032 fits tightly (sticking part is as shown in the dashed circle of the upper and lower both sides of Fig. 3 B medium wavelength conversion layer), enclose the seam between two the first casing assemblies, namely second housing by the joint sealing between the first casing assembly therein.
Illustrated by above embodiment and be appreciated that, second housing can close the first shell completely, also only can close the seam (second housing closes a kind of form that the first shell can be understood as the seam between closed first casing assembly completely) between the first casing assembly, the object extending light source serviceable life can be reached like this.
The structural representation of another embodiment of optics module of the present invention as shown in Figure 4 A.Comprise wavelength convert sabot 402a with the embodiment shown in Fig. 2 unlike, Wavelength converter 402 and drive the drive unit 402c of this wavelength convert dial rotation.Wavelength convert rotating disk 402a comprises fin 402d, for producing centrifugal air-flow 491 when wavelength convert rotating disk 402a rotates.Wavelength convert rotating disk 402a also comprises the wavelength conversion layer 402b of circle distribution, after the laser excitation that wavelength conversion layer 402b is focused, launch Stimulated Light.Because wavelength convert rotating disk 402a rotates, each point on such wavelength conversion layer 402b is periodically irradiated by laser and excites, and this is conducive to the diffusion of wavelength conversion layer amount of localized heat.
The front elevation of wavelength convert rotating disk and the fin on it as shown in Figure 4 B.Visible, fin 402d along the circumferential direction distributes and is that centrifugal divergent shape extends, and is appreciated that and can produces centrifugal air-flow 491 between fin 402d when wavelength convert dial rotation as the principle of centrifugal fan.This centrifugal air-flow can take away the heat on wavelength convert rotating disk, is reached for the effect that wavelength conversion layer 402b lowers the temperature.Certainly in order to produce centrifugal air-flow, the design of fin 402d can also be other form, and this belongs to prior art and does not repeat herein.
In the present embodiment, at least part of inwall of the second housing 404 flowed through at air-flow 491, comprise the shape of fluctuating or fin 409 to increase its surface area.Like this, heat entrained on air-flow 491 just can pass to second housing 404 more fully, and it is surperficial and outside that the heat of such second housing inside just can be transmitted to second housing.The fin 409 used in the present embodiment can be risen and fallen by other shape and replace, and such as bar shaped or point-like raised or sunken, can reach the effect increasing this part inner wall surface of second housing.Certainly even without fin 409, the heat on air-flow 491 also partly can pass to second housing.
Preferably, in the present embodiment, in the region that air-flow 491 flows through, also porosint is comprised.Porosint can dust in adsorption gas flow, and make the dust great majority entering second housing inside be attracted on porosint, the probability entering the optical system of the first enclosure is further reduced.Porosint can be metal polyporous material, can also play the effect of heat conduction like this.Certainly, porosint also can be combined with the shape 409 of the fin in Fig. 4 A or fluctuating.

In the embodiment above, Stimulated Light is all the direction outgoing in the other direction along laser incidence.In another embodiment of optics module of the present invention, as shown in Figure 6, with the embodiment shown in Fig. 4 A unlike, Wavelength converter 602 comprise transparent wavelength convert rotating disk 602a and the wavelength conversion layer 602b on it, wavelength conversion layer 602b by after laser excitation the Stimulated Light 612 that produces can continue to propagate along the direction of laser.Second housing also comprises light-emitting window 604b and covers the bright dipping cover plate 622 on light-emitting window, and Stimulated Light just can through light-emitting window 604b outgoing.In addition, with the embodiment shown in Fig. 4 A unlike, the wavelength convert rotating disk 602a in Fig. 6 does not have fin, this is because fin is not necessary, when the heat that wavelength conversion layer sends is not too high, can lose in wavelength convert dial rotation.
As can be seen from the explanation of above multiple embodiment, in the present invention, the light inlet of the first shell and second housing and light-emitting window have multiple possibility and combination, and those skilled in the art can according to actual conditions designed, designed.Wherein, the light inlet of the first shell is only had to exist, because it needs for receiving laser.
In the explanation of above multiple embodiment, light inlet and light-emitting window often have employed cover plate to close, and this also can change in actual applications.Such as in the embodiment shown in fig. 5, the first shell just employs lens 521 as light-emitting window, and lens 521 also can be understood to the cover plate of light-emitting window in this case certainly.Also have a kind of may, the first shell and/or second housing are made by transparent material, and now just do not need the light-emitting window reserving especially or process or light inlet, also do not need special cover plate, the place of light transmission is exactly light inlet or light-emitting window.Therefore, in the present invention, light inlet or light-emitting window refer to and can guide light incidence or outgoing, do not affect the light-path of the first shell and second housing closure simultaneously.
In multiple embodiments of above optics module, all include Wavelength converter, this is because be in daily use at LASER Light Source medium wavelength conversion equipment, but this not represent Wavelength converter for the present invention be necessary.Even without Wavelength converter, or Wavelength converter is in the outside of second housing, and the first shell and second housing still can well protect optical system be not subject to the absorption of extraneous dust thus keep high-level efficiency.
