Description
Technical field
The present invention relates to laser projection field, the more particularly to radiator structure for laser projection fluorescent wheel.
Background technology
Laser projection of the laser diode as light source is used at present, is typically existed using blue laser diode, wavelength
Between 400-480nm, by the way that blue laser diode is excitated red, green emitting phosphor produces red green visible ray, or excites Huang
Color fluorescent material, then red visible is filtered out by filter, the blue light that blue laser diode ejects can be directly as indigo plant
Color light source.Because the laser that laser diode is sent is after multiple lens optically focused, unit area luminous power is very big, is shining
When being mapped on fluorescent material, heat can be produced, separately (dust is attached to meeting on fluorescent material because fluorescent material there are strict requirements to dust
Reduce luminous efficiency and life-span), as shown in figure 1, so what many producers typically considered is to make the cavity where fluorescent wheel
Sealing, so, the radiating of fluorescent wheel is difficult to ensure, this problem particularly just seems in the projector of high lumen
It is especially prominent.
The content of the invention
The technical problem to be solved in the present invention is：A kind of radiator structure for laser projection fluorescent wheel is provided, reduced
Temperature when fluorescent wheel works.
To solve the above problems, the technical solution adopted by the present invention is：For the radiator structure of laser projection fluorescent wheel,
Including flexible pipe, the first fan, the second fan and airtight cavity for placing fluorescent material and motor, on the airtight cavity
Air inlet and air outlet are provided with, the air inlet is connected by flexible pipe with the outlet air end of first fan, and the air outlet leads to
The air intake that flexible pipe is crossed with second fan is connected, and the air intake of first fan sets anti-dust filter mesh.
Further, the distinguished and admirable radial direction for the airtight cavity being entered by the air inlet blows to fluorescent wheel.
Further, the quantity of the air inlet or air outlet is multiple.
Further, first fan and the second fan are aerofoil fan.
The beneficial effects of the invention are as follows：Because the present invention on airtight cavity by opening up air inlet and air outlet, utilize
Air inlet and the fan on air outlet both sides make airtight cavity produce flowing, temperature when can reduce fluorescent wheel work, delay fluorescent material
Decay, improve the life-span of fluorescent material and motor on fluorescent wheel, and due to there is provided anti-dust filter mesh, reducing fluorescent wheel work
While Shi Wendu, it also avoid entering inside airtight cavity the risk of dust.
Brief description of the drawings
Fig. 1 is the structure chart at fluorescent wheel in existing laser projection；
Fig. 2 is to open up the structure chart after opening in laser projection at fluorescent wheel；
Fig. 3 is the structure chart of embodiment.
Numbered in figure：1 is fluorescent wheel, and 2 be airtight cavity, and 3 be air inlet, and 4 be air outlet, and 6 be flexible pipe, and 8 be air intake wind
Fan, 9 be extractor fan, and 10 be anti-dust filter mesh.
Embodiment
Embodiment provides one kind and uses fluorescent material type DLP projector, the fluorescence of DLP projector as shown in Figures 2 and 3
Structural representation at wheel, embodiment are provided with two holes on the closed cavity 2 for setting fluorescent wheel 1：Air inlet 3, air outlet 4；
Air inlet 3, air outlet 4 are connected to the air intake of the outlet air end of air inlet fan 8, extractor fan 9 with rubber hose 6 respectively, simultaneously
The air intake of air inlet fan 8 has also installed anti-dust filter mesh 10 additional.
When DLP projector works, the closed cavity 3 of fluorescent wheel 1 is set to utilize air inlet 3, flexible pipe 6, air inlet fan 8 outer
The natural wind in portion is conveyed into closed cavity 2, is taken away the hot blast of inside using air outlet 4, flexible pipe 6, extractor fan 9, so as to
So that cavity flow, effectively reduce fluorescent wheel 1 work when temperature, delay fluorescent material decay, improve fluorescent wheel on fluorescent material and
The life-span of motor；The anti-dust filter mesh 10 of setting can avoid bulky grain dust from being blown into cavity, influence the fluorescent wheel life-span.
The present embodiment also controls wind direction when implementing so that enters the airtight cavity 2 by the air inlet 3
Distinguished and admirable radial direction blow to fluorescent wheel 1, it is distinguished and admirable will not front vertical fluorescent wheel, avoid causing fluorescent wheel to rotate disequilibrium.
In use, it is noted that compressing fan when rubber guide duct is installed, gas leakage is avoided, while to carry out fixation,
Avoid folding and influence air quantity and wind speed.Air inlet fan 8, extractor fan 9 can be, but not limited to aerofoil fan, and other are all to produce
The fan of raw air flow can be with.Airtight cavity 2 sets the quantity of air outlet 3 and air inlet 4 to be not limited to one, can during application
It is added to according to actual conditions multiple.
The general principle of the present invention and main feature are the foregoing described, the description of specification simply illustrates the original of the present invention
Reason, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes and improvements
It all fall within the protetion scope of the claimed invention.
