Abstract
The utility model discloses a color wheel in a projection machine, which solves the defects that a current color wheel is inconvenient to process, and the overall planeness of filter discs on the color wheel is poor, so that the light transmittance effect is influenced. The Technical measure adopted is as follows: the color wheel in the projection machine comprises a connecting part and the dish-shaped filter discs arranged on the connecting part; the color wheel in the projection machine is characterized in that the filter discs are single elements; light transmittance areas are arranged between the outer edges of the filter discs and the connecting part; a plurality of sector coating areas are arranged on the light transmittance areas; and antireflection coatings which can transmit single-color lights of different wavelengths are coated on the surfaces of different coating areas.
Description
Technical field
The utility model relates to the parts in a kind of projector, relate in particular in a kind of projector, in rotary course, be used for successively seeing through the monochromatic colour wheel of different wave length.
Background technology
Follow the develop rapidly of DLP digital light treatment technology, the DLP digital projector more has technical advantage comparing with traditional LC D projector.In DLP projector, its color mainly relies on colour wheel to realize, traditional colour wheel is by only realizing that through being adhesive on the transparent substrate this makes that on the one hand filter disc thickness is bigger through different monochromatic filter discs with several, to bonding technological requirement height.On the other hand, the faying face between adjacent two filter discs is less relatively, the firm connection between this unfavorable filter disc, and the junction between adjacent two filter discs, and the adhesive-layer between filter disc and the substrate can have influence on translucent effect.And the flatness of filter disc integral body also is difficult for guaranteeing that the production cost is higher.
Chinese invention patent application (application number: disclose a kind of colour wheel and projector 200910130617.4).A kind of projector, have: the light supply apparatus that penetrates white light, colour wheel, display element, cooling fan, to arrive the light source-side optical system of above-mentioned display element from the photoconduction light of above-mentioned light supply apparatus, the projection side optical system of the image projection that will penetrate from above-mentioned display element to the screen, and projector's control gear of controlling above-mentioned light supply apparatus and display element, wherein this colour wheel is, have a plurality of sections zones, each section zone is, a face is implemented the coating that the band of light that makes complementary color sees through, the part of another face is implemented the coating that the band of light that makes primary colors sees through.
Colour wheel in this application also is to adopt traditional job operation to process, and also above-mentioned defective can occur in the production of reality with in using.
Summary of the invention
For overcoming above-mentioned defective, the utility model technical issues that need to address are: the colour wheel in a kind of projector is provided, and it requires low to processing technology, and quality is easier to guarantee that translucent effect is good.
In order to solve the technical problem, the technical solution of the utility model: the colour wheel in a kind of projector, comprise connection part and the dish-shaped filter disc of being located on the connection part, it is characterized in that, described filter disc is a monomer spare, be photic zone between filter disc outer rim and the connection part, on photic zone, be provided with some fan-shaped plated films district, on different surfaces, plated film district, be coated with and see through the monochromatic anti-reflection film of different wave length.This colour wheel is in process, and the anti-reflection film in each fan-shaped plated film district is processed successively, when plating anti-reflection film on to certain plated film district, filter disc photic zone remainder is covered with the stratiform thing, and only exposed target plated film district can realize plating anti-reflection film.The rest may be inferred, thereby photic zone partly forms anti-reflection film of different nature on filter disc, and these anti-reflection films cover the whole photic zone of filter disc together.
As preferably, the thickness of described anti-reflection film is 4-6 μ m.Anti-reflection film is configured to the translucent effect that this thickness can effectively guarantee colour wheel.
As preferably, all anti-reflection films all are positioned on the same surface of filter disc.This had both made things convenient for the processing to anti-reflection film, also can control the translucent effect of colour wheel simultaneously.
The beneficial effects of the utility model are:
Utilize the pattern technology of optical film can be directly the anti-reflection film of different colours to be plated on the same substrate, make the integral type colour wheel, it is all having more advantage than traditional colour wheel aspect planarization, the thermotolerance, can realize that the multizone of same color distributes simultaneously.Because filter disc is a monomer spare, thereby saved the bonding process that has different anti-reflection film filter discs, colour wheel integral intensity and flatness all can guarantee that the incident angle of rayed on colour wheel helps the assurance of projector's image developing effect along with the rotation high conformity of colour wheel.When light penetrated between adjacent two anti-reflection films the position, all-in-one-piece filter disc can not produce difference to the effect that penetrates of light.
Description of drawings
Fig. 1 is the structural representation of the colour wheel in the utility model projector.
Embodiment
See among the figure that the structure of the colour wheel in the utility model projector comprises connection part 1 and the dish-shaped filter disc of being located on the connection part 12, connection part 1 and filter disc 2 concentric settings.Connection part 1 is to be used for linking with the motor power output shaft, and projector is when work, and colour wheel can rotate under the drive of motor.
Between filter disc 2 outer rims and the connection part 1 is photic zone, has some fan-shaped plated films district on the photic zone, is coated with the anti-reflection film 3 of different physical characteristicss on different surfaces, plated film district.This anti-reflection film 3 can see through the monochromatic light of specific wavelength, and ends the monochromatic light of other wavelength.
Claims (3)
