The modularized air-tight dustproof optical machine structure comprises an optical module, a light source module, a power module and corresponding connecting lines, wherein the optical module and the light source module are fully separated and are respectively installed in respective shells; the optical passage entrance of the optical module is in close contact with the light source module and a transparent dustproof cover is installed on an optical module shell at the entrance; and the power supply module is installed in a power supply module shell.

Description

The airtight dustproof mechanical-optical setup of a kind of modularization

Technical field

The utility model relates to the airtight dustproof mechanical-optical setup of a kind of modularization.

Background technology

Constantly perfect along with the development of DLP technology and rear-projection splicing, DLP rear-projection spliced display wall is applied in all trades and professions more and more widely.Present DLP large screen display wall all adopts the box-type splicing construction, and every display unit is made up of rear-projection casing, ray machine, catoptron and screen, adopts the imaging of primary event formula back projection mode, is spliced into an entire image jointly by a plurality of unit screen.Wherein the drop shadow effect of ray machine has directly determined the display effect of display unit.And the dust in long-time running process influence is one of major reason to influence ray machine drop shadow effect, how in assurance ray machine internal heat dissipating demand, strengthens the anti-dust performance of ray machine as far as possible, becomes the problem that each producer falls over each other to study.

Present ray machine all is integrated, and manufacturer is placed on ray machine in the unified shell, leaves thermal window at the necessary position of shell, thereby guarantees shedding of ray machine internal heat.But these louvres make the ray machine shell can not guarantee the airtight anti-dust performance of ray machine inside, ray machine contains a large amount of circuit blocks, the magnetic field that these parts produce is easy to adsorb dust, and dust can disorderly fly everywhere along with blowing in ray machine inside of radiating airflow, enter light path part inside, thereby influence the drop shadow effect of ray machine.

The utility model content

The purpose of this utility model provides a kind of simple in structure, easy to use exactly for addressing the above problem, and under the prerequisite of the radiating effect that guarantees ray machine, guarantees the airtight dustproof mechanical-optical setup of modularization of airtight dustproof effect of the light path part of ray machine simultaneously.

For achieving the above object, the utility model adopts following technical scheme:

The airtight dustproof mechanical-optical setup of a kind of modularization, it comprises optics module, light source module, power module and corresponding connecting line, wherein the optics module separates fully with the light source module and is installed in respectively in separately the housing; The light source module is close in path channels porch at the optics module, on the optics module casing of this porch transparent dust cover is installed also; Power module also is installed in the housing of oneself.

Described optics module casing is complete closed, is closed to close by the one-shot forming casting aluminium material of two die sinkings to form, and closes the airtight dust ring that there is a circle elastomeric material at the place of closing.

Be provided with heat dissipation channel in the housing of described light source module and power module.

The designed mechanical-optical setup of the utility model mainly comprises three parts, is respectively optics module, light source module, power module and connecting line.

The optics module is a light from producing the back until after becoming coloured image projection and go out the entire path of process, comprise all opticses of ray machine, i.e. optical filter, optical wand, colour wheel, prism, dmd chip, DMD mainboard and camera lens etc.It adopts existing equipment to get final product.

The light source module can be a UHP bulb module, also can be the led light source module, produces the required light source of projector.

Power module comprises apparatus for lighting up, ray machine power module etc.

Connecting line comprises some data lines and power lead, connects power supply module and light source module, and power supply module and optics module, is responsible for the power supply that the power supply module is given light source module and optics module, and the control communication of optics module and power supply module and signal transmission.

The optics module separates fully with the light source module in the utility model, the light source module is close in the path channels porch that is positioned at optics module left side, the housing of optics module herein embeds a transparent dust cover, and the light that the light source module produces need pass the path channels that transparent but complete airtight dust cover enters the light source module.The optics module separates fully with the power supply module, has shell separately respectively, only transmits information by connecting line.It is airtight fully that the optical mode assembly housing needs, and closed to close by the one-shot forming casting aluminium material of two die sinkings to form, and closing the place of closing has an airtight dust ring that encloses elastomeric material.Light source module and power module shell do not need airtight, should leave enough heat dissipation channels to guarantee equipment cooling.

The beneficial effects of the utility model are: both satisfied the radiating requirements of light source and power supply module, guaranteed the airtight dustproof requirement of optics module again.
