Abstract
The present invention discloses one kind of monochip color wheel and its making process. The making process includes: forming two or more color filter films on one transparent substrate, cutting to form circular color filter wheel, and hinging the color filter wheel to one driving motor directly or indirectly through one metal ring. These color filter films form symmetrical or asymmetrical fan-shaped arrangement with two or more kinds of filmed sectors. The present invention is superior to available technology, and the color wheel has high dynamic balance, low noise and smooth rotation.
Description
Technical field
The present invention relates to a kind of colour wheel and manufacture method thereof, refer to that especially the optical filter of a colour wheel forms colored filter film earlier on a substrate, and then it is cut into the monochip color wheel and the manufacture method thereof of the color block filter of a circle.
Background technology
Present color block filter production method has two kinds, and a kind of is tiled, pieces the fan-shaped colored filter of set shape and angle together gummed earlier, makes it become the color block filter of sub-circular; Another kind is a substrate-type, and the fan-shaped optical filter of set kenel and angle is glued on the substrate of a circle, becomes the color block filter of another kenel.
With U.S.'s patent of invention is example the 5th, 868, No. 482, and this patent discloses a colour wheel and is assembled on the circular metal ring with the fan-shaped eyeglass of multi-disc, becomes the color block filter of a circle.Because the center pit of this becket just is fixed in the rotating shaft of motor the high speed rotating so can be subjected to motor driven.
With U.S.'s patent of invention is example the 5th, 371, No. 543, discloses a colour wheel and sticks in the eyeglass with the fan-shaped eyeglass of multi-disc, thereby become the color block filter of a circle, then these semi-manufacture and motor is composed colour wheel.
But owing to the cutting of fan-shaped eyeglass, assembling, a little skew or defective are always arranged unavoidably with gummed, this can allow the quality of color block filter have a greatly reduced quality, not only can influence the outward appearance of colour wheel, the phenomenons such as attenuating that mobile equilibrium is not good enough, noise reaches the life-span greatly in the time of also can producing the colour wheel rotation.
Summary of the invention
The technical problem to be solved in the present invention is: a monochip color wheel and manufacture method thereof are provided, it is earlier all colored filter film to be formed on the single glass eyeglass, and then it is cut into the color block filter of a circle or garden annular, to overcome the defective of above-mentioned known method.
For this reason, the present invention at first provides a kind of manufacture method of monochip color wheel, comprising: step 1, preparation one transparency carrier, and on this substrate, form the light filter film of multiple color; Step 2, cut this square substrate and this light filter film, make it become the color block filter of a circle; Reach step 3, connect this a circular color block filter and a motor, by this color block filter of this motor driven.
The present invention also proposes a kind of monochip color wheel, comprising: a motor; And a colour wheel optical filter, be connected with this motor and be driven by it, have a substrate on this color block filter, on this substrate, have the light filter film of multiple color simultaneously.
The present invention also proposes another kind of monochip color wheel, and it comprises: a motor; And a becket, join with this motor and be subjected to this motor driven; One colour wheel optical filter, be connected with this becket and between accept this motor driven, this color block filter has a substrate, has the light filter film of multiple color on this substrate simultaneously.
Characteristics of the present invention and advantage are: method of the present invention is to form predetermined colored filter film earlier on substrate, just extract then, become the color block filter of circle or garden annular, therefore will not have eyeglass flatness, out of roundness, with phenomenons such as concentricity is bad, do not have because the slit is excessive between the bad eyeglass that produces of fan-shaped eyeglass cutting, be difficult to problem such as assembling yet.In other words, because each optical filter of colour wheel of the present invention is coated with all earlier or is pasting on same substrate and extracts, will have significantly for the dynamic unbalance that improves colour wheel, noise phenomenon and benefit.The colored filter film of monochip color wheel of the present invention therefrom mind-set presents fan-shaped permutation and combination outward, and it is fan-shaped to form two kinds, three kinds or multiple plated film, also may be that symmetry or asymmetrical plated film are arranged.The present invention has overcome the defective of prior art, can form a high mobile equilibrium, low noise, reach the smooth-going colour wheel of running.

Embodiment
The present invention proposes a kind of monochip color wheel and manufacture method thereof, the manufacture method of this monochip color wheel is the colored filter film that forms two or more on a square transparency carrier earlier, just cut into the color block filter of a circle then, can directly it be glued on the motor, or utilize a becket to be connected with a motor indirectly, be driven by it.
According to the manufacture method that the present invention implemented, its step can comprise: first step, as shown in Figures 1 to 4, be on a square substrate 31, to be coated with the light filter film 33 of the light filter film 32 of first kind of color, second kind of color, the light filter film 34 of the third color, and the light filter film 35 of the 4th kind of color.This square substrate 31 can be glass plastic or quartzy material, and this light filter film can be respectively redness, green or blue light filter film.The preferably, attractive in appearance for promoting, when being coated with, also can form a circular pelmatogram 310, mark or pattern, as the benchmark of follow-up cutting step centering and increase the attractive in appearance of colour wheel in the center.
According to United States Patent (USP) the 5th, 371, No. 543 disclosure, the light filter film 32,33,34 of this step or 35 etc. also can separately be coated on the different transparent thin films in advance, and then with resistant to elevated temperatures optical cement (high temperature, optically transparent adhesive; For example NOA-61 or other equivalent optics jelly of Norland company) it is pieced together one by one be bonded on the square substrate 31.Separately be coated with the mode of piecing together again in square substrate 31 individually thus, will save and recycle expense and the trouble that mask (light shield) covers nonclient area when being coated with, reduce cost.
Second step to shown in Figure 6, is path 36 cuttings along a circle as Fig. 5, this square substrate 31 and light filter film 32,33,34,35 is slit into the color block filter 30 of a circle or annular.
Third step as shown in Figure 7, sticks on a becket 30 with this color block filter 30 and accepts motor 10 and drive.This step also can change color block filter 30 directly is glued on the motor 10 (not shown) with its high-speed rotation.
These colored filter film can outwards present fan-shaped permutation and combination from the center of color block filter 30, and it is fan-shaped to form two kinds, three kinds or multiple plated film, also may be that symmetry or asymmetrical plated film are arranged.This kind method can form a high mobile equilibrium, low noise and the smooth-going colour wheel that turns round, and will improve the colour wheel problem that the tradition gummed is produced.
Though the present invention discloses with specific embodiment; but it is not in order to limit the present invention; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present invention and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that scope of patent protection of the present invention is done.
