Description
Technical field
The present invention relates to a kind of lamp of projector fixed sturcture, particularly relate to a kind of lamp of projector fixed sturcture avoiding affecting because of distortion optical property.
Background technology
In the structure of projector's product, light engine (OpticalEngine) is an important key component, and it includes a lamp light source and an optical module.Described lamp light source is modular structure, has the composition components such as bulb, lampshade, lamp socket and Lamp cup, irradiate in order to produce a projecting beam towards described optical module.Described optical module is similarly modular, colour wheel, integration rod, projection lens, polarization light splitting water chestnut mirror will be included and close the assemblies such as light water chestnut mirror and set with a ray machine housing, projecting beam in order to guide described lamp light source carries out color-division and closes the running of the optics such as light, with formed an image strip again by described projection lens by image projection on screen.Therefore, the projecting beam of described lamp light source must have accurate matching design with described optical module, and light beam of light source just can be made to reach projection and video picture effectively by the running of optical characteristics.The group of current described lamp light source and described optical module connects, be connected with the described ray machine housing of described optical module by the described Lamp cup of described lamp light source, after each assembly of lamp light source described in described Lamp cup bearer connection, make described lamp light source and described optical module on correct relative position, from top to bottom described Lamp cup is locked on described ray machine housing with two fixed screws.In general, only fixing in upper end structure, after described Lamp cup carries all described lamp light source assemblies, underslung fixed form can be formed, the carrying of described lamp light source is the distortion easily causing described Lamp cup, thus described lamp light source and the correct relative position of described optical module will change, and also therefore can affect the optical characteristics of described light engine, reduce the quality of projector's product.How to avoid described lamp light source and described optical module to combine the distortion of fixed sturcture, should be studied again to be improved.
Summary of the invention
In view of this, the lamp of projector fixed sturcture providing a kind of location structure firm is necessary.
The invention provides a kind of lamp of projector fixed sturcture, it comprises a lamp module, a connecting elements and a ray machine housing, described connecting elements has first side and second side, described first side connects described lamp module, described second side is positioned at the back side of described first side and connects described ray machine housing, described lamp module is oppositely arranged by described connecting elements and described ray machine housing, and at least two combined members that described connecting elements and described lamp module have are connected.
Compare prior art, lamp of projector fixed sturcture of the present invention, two reverse side had by described connecting elements connect described lamp module and described ray machine housing respectively, make described connecting elements can by the conformability vibrational power flow of described connection side, stable connection simultaneously on the tram described lamp module being remained on relatively described ray machine housing, therefore avoid the distortion of described lamp module to occur, improve the quality of projector optical characteristic.
