Embodiment
For making that purpose of the present invention, structure, feature and function thereof are had to further understanding, hereby coordinate embodiment to be described in detail as follows.
Fig. 1 shows the schematic diagram of an embodiment who the invention provides light-source system, and Fig. 2 shows the decomposing schematic representation of this light-source system.As depicted in figs. 1 and 2, this light-source system comprise the light supply apparatus (not shown), for light supply apparatus being installed to light source holder 1 and light source cooling device wherein.Wherein the light source cooling device comprises fan assembly 2, air guide duct 3 and stop means 4.
Fig. 3 shows the schematic diagram at another visual angle of light source holder in the present embodiment, please be simultaneously referring to Fig. 3 and Fig. 1,2, sidepiece at light source holder 1 has air inlet 11, outside cold wind will enter in light source holder 1 by this air inlet, with the light supply apparatus in light source holder 1, carry out cooling.It is netted that the air inlet 11 of light source holder 1 can be honeycomb, can farthest utilize the area of light source holder 1 sidepiece when taking into account structural strength.
Fig. 4 shows the schematic diagram at another visual angle of the present embodiment fan device.Please be simultaneously referring to Fig. 1,2 and Fig. 4, fan assembly 2 has air outlet 21, fan assembly 2 is the mobile power that provides of cold wind in the present embodiment, in the present embodiment, the fan in fan assembly 2 can adopt turbofan.
Air guide duct 3 is incorporated into the cold wind of fan assembly 2 air outlet 21 outputs at air inlet 11 places of light source holder 1.Air guide duct 3 has air inlet and air outlet, air guide duct 3 air inlets communicate with the air outlet 21 of fan assembly 2, be fixed with stop means 4 on the air outlet edge of air guide duct 3, stop means 4 matches with the air inlet of light source holder 1, make the air outlet of air guide duct 3 to aim at the air inlet 11 of light source holder 1, thereby the cold wind of fan assembly 2 outputs is imported in light source holder 1 efficiently, and then the light supply apparatus in effective cooling light source holder 1.
Please have chute 41 on stop means 4 simultaneously referring to Fig. 1 and Fig. 2, air inlet 11 edges of light source holder 1 can be slipped in this chute 41, with this, complete coordinating between the air inlet 11 of stop means 4 and light source holder 1.By the design of chute 41, can realize relatively easily aiming between air guide duct 3 and light source holder 1 air inlet 11.
In order to slip into the degree of stability after chute 41 in the edge that further increases the air inlet 11 of light source holder 1, a kind of preferred embodiment in, be provided with the limited post 42 to upper process on the bottom interior wall of chute 41, edge bottom at the air inlet 11 of light source holder 1 has corresponding spacing hole (not shown), in the time of in the edge of the air inlet 11 of light source holder 1 slips into this chute 41, the limited post 42 of stop means 4 inserts in the spacing hole of light source holders 1.
Air guide duct 3 in practice can be one-body molded, also can be by upper pipe wall components 31 and lower pipeline wall components 32 fastenings form as shown in Figure 2.Fig. 5 and Fig. 6 show respectively the schematic diagram at another visual angle of upper pipe wall components 31 and lower pipeline wall components 32.The upper pipe wall components 31 of air guide duct and lower pipeline wall components 32 are fastened in the hole clipping on another by the buckle on one of them, in the air guide duct shown in Fig. 2, Fig. 5 and Fig. 6, especially, buckle 311 is arranged on upper pipe wall components 31, and snap fit 321 is arranged on lower pipeline wall components 32.After upper pipe wall components 31 and lower pipeline wall components 32 snap together, the air inlet part 32a of the air inlet part 31a of upper pipe wall components 31 and lower pipeline wall components 32 forms the air inlet of air guide duct 3, and the air outlet part 32b of the air outlet part 31b of upper pipe wall components 31 and lower pipeline wall 32 forms the air outlet of air guide duct 3.
As shown in Figure 2, when air guide duct 3 adopts upper pipe wall components 31 and lower pipeline wall components 32 fastenings to form, stop means 4 can be fixed on the lower pipeline wall components 32 of air guide duct 3.
In the light-source system shown in Fig. 1 and Fig. 2, reason due to projector's interior location design, the air outlet 21 of fan assembly 2 towards with light source holder 1 sidepiece air inlet 11 towards being 90 angles, therefore this just needs the air guide duct 3 can be by the 90-degree rotation that flows to of the cold wind of fan assembly 2 outputs, consideration based on such, in Fig. 1 and Fig. 2, air guide duct 3 is the arcuate shape that central angle is 90 degree on the wind-guiding path so that the air inlet of air guide duct 3 towards the air outlet with air guide duct 3 towards being 90 degree angles.Those skilled in the art should be understood that, in practice, according to the air outlet 21 of fan assembly 2 and light source holder 1 sidepiece air inlet 11 towards angle different, the central angle of the arcuate shape of air guide duct 3 on the wind-guiding path also can be different, in a word the air outlet 21 of fan assembly 2 and light source holder 1 sidepiece air inlet 11 towards between while having angle, air guide duct 3 is curved on the wind-guiding path.
If the air outlet 21 of fan assembly 2 is over against the air inlet 11 of light source holder 1 sidepiece, air guide duct 3 does not need the flow direction of the cold wind of fan assembly 2 outputs is rotated, now air guide duct 3 type linearly on the wind-guiding path.
In light-source system in the present embodiment, air guide duct 3 need to be assembled on fan assembly 2, so that the air inlet of air guide duct 3 can communicate with the air outlet 21 of fan assembly 2.The specific implementation that air guide duct 3 is assembled on fan assembly 2 can have a variety of, in a kind of specific implementation shown in Fig. 1 and Fig. 2, air inlet edge at air guide duct 3 is provided with fixed part 33, fixed part 33 is fixed on the edge of fan assembly 2 air outlets 21, so that the air inlet of air guide duct 3 communicates with the air outlet 21 of fan assembly 2.Particularly, be provided with fixed orifice 331 on fixed part 33, the position corresponding with the fixed orifice 331 of fixed part 33 at fan assembly 2 is provided with threaded hole 23, by screw 24 from through the fixed orifice 331 of air guide duct 3 to the threaded hole 23 of fan assembly 2 and tighten, and then will near the air inlet of air guide duct 3, part be fixed with fan assembly 2.
As can be seen here, light source cooling device in light-source system in the embodiment of the present invention and this light-source system, by the stop means on air guide duct, with the air inlet of light source holder, match, make the air outlet of wind-guiding photoconduction aim at the air inlet of light source holder, reduced the difficulty of assembling, therefore can guarantee the precision of aiming at, effectively improve the cooling effect of the light supply apparatus in the light source holder.
The present invention is described by above-mentioned related embodiment, yet above-described embodiment is only for implementing example of the present invention.Must be pointed out that, the embodiment disclosed does not limit the scope of the invention.On the contrary, the change done without departing from the spirit and scope of the present invention and retouching, all belong to scope of patent protection of the present invention.
