Abstract
The utility model discloses a dustproof color wheel for a DLP (Digital Light Processing) projecting apparatus, comprising a color wheel assembly and a motor arranged thereon, wherein the color wheel assembly is connected with a positioning assembly fixed on a bare engine connecting body; and the positioning assembly is also provided with an inductive head, and the color wheel assembly is provided with a color wheel shielding protective cover arranged on the positioning assembly. In the utility model adopting the technical scheme, the color wheel-shielding protective cover is additionally arranged on the color wheel so as to prevent dust from attaching thereto and avoid color cast of the color wheel or declined brightness. Proved by experiments, the technology can effectively prevent dust from depositing, prolong the service life of the color wheel, ensure the long-term stability of image quality and greatly solve the problems of color cast of pictures and declined uniformity caused by dust.
Description
Technical field
The utility model relates to a kind of DLP projector colour wheel, specifically relates to a kind of dustproof colour wheel of DLP projector.
Background technology
At present, DLP (Digital Lighting Process) Digital Light Processor projector has obtained greatly using in the middle of education and instruction.But the environment in classroom is abominable, and colour wheel long-play in the dust atmosphere of classroom easily dyes dirt in the projector, can cause projector output to produce drawbacks such as colour cast, image blurring and color spot, add the ventilation that influences wind path because of laying dust, cause the colour wheel heat radiation bad, aging easily, the lost of life.
Summary of the invention
The purpose of this utility model provides and a kind ofly can prevent that colour wheel dyes dirt in the projector, the colour wheel thereby the short out-of-focus projection instrument that prolongs colour wheel serviceable life prevents dust.
For achieving the above object, the utility model provides following technical scheme:
The utility model comprises color block component and is arranged on motor on the color block component, and color block component is connected with positioning component, and positioning component is fixed on the ray machine connector; Also be provided with inductive head on the described positioning component, described color block component is provided with colour wheel shielding protection cover, and colour wheel shielding protection cover is arranged on the positioning component.
Described colour wheel shielding protection cover is a square casing.
Described inductive head is arranged in the inductive head protective cover, and the inductive head protective cover is fixed on the positioning component.
Adopt the utility model of technique scheme, on colour wheel, have additional colour wheel shielding protection cover, thereby can prevent dust stickup colour wheel, cause colour wheel colour cast or brightness to reduce.The experiment proved that this technology can effectively prevent the deposition of dust, prolong the life-span of colour wheel parts, guarantee the long-term stability of image quality, reduce greatly because the problem that picture colour cast that dust causes and uniformity coefficient descend.
Description of drawings
Accompanying drawing is an one-piece construction synoptic diagram of the present utility model.
Embodiment
As shown in the figure, the utility model comprises color block component 1 and is fixed on motor 2 on the color block component 1, under the drive of motor 2, and color block component 1 high-speed rotation.Color block component 1 is connected with positioning component 4, and positioning component 4 is fixed on the ray machine connector 7, and also is provided with inductive head 5 on positioning component 4.
For preventing that dust from falling on the colour wheel, above-mentioned color block component 1 is provided with colour wheel shielding protection cover 3, and colour wheel shielding protection cover 3 is fixed on the positioning component 4.Wherein, colour wheel shielding protection cover 3 is a preferred forms for square casing.
In addition, in the utility model, inductive head 5 can be arranged in the inductive head protective cover 6, and inductive head protective cover 6 is fixed on the positioning component 4.
Principle of work of the present utility model is:
The utility model prevents that by colour wheel shielding protection cover 3 is installed dust from entering in the projector on color block component 1, thereby effectively solves the dustproof problem of light path system.In addition, also can prevent colour wheel in the process of running up, the vitreum of color block component 1 owing to the friction or the overheated glass fragment that forms that breaks that causes get on other parts of projector with the high speed rotating of motor, avoid the destruction of deep layer.
