Embodiment
A fundamental purpose of the present invention is to provide a kind of projector with rotary lens module.
See also Fig. 1 and Fig. 2.Fig. 1 is the outward appearance that illustrates according to the projector 10 of first preferred embodiment of the present invention.Fig. 2 is the skeleton view of projector 10.Projector 10 comprises a camera lens module 11, a base module 12 and a link block 13.Camera lens module 11 comprises the optical devices in order to the projection optics message, this optical devices general reference camera lens 11A and ray machine (optical engine) 11B as shown in Figure 2, and the optical devices of the projector of various different types may be slightly variant.Base module 12 comprises a light source 12A and a power supply unit 12B.Light source 12A is in order to provide ray machine 11B light and to have an optical axis 14.Power supply unit 12B is in order to supply electric power to ray machine 11B and light source 12A.Link block 13 can be a coaxial connector (co-axial connector) between camera lens module 11 and base module 12, in order to connect camera lens module 11 and base module 12, make camera lens module 11 can along or against the direction of arrow 15 indications with respect to base module 12 rotations.For keeping light that light source 12A provided when camera lens module 11 rotations, still can be projected to the device that receives light among the ray machine 11B fully, for example lens or a catoptron, the optical axis 14 of the turning axle of camera lens module 11 and light source 12A must be coaxial (co-axial) haply.
In actual applications, light source 12A generally includes a bulb.This bulb can be an ellipsoid bulb (ellipsoid lamp) or directional light bulb.If this bulb is the ellipsoid bulb, then link block 13 can further comprise a photoconductive tube (light pipe) 13A shown in figure two.The light system that this bulb sent focuses on the optical centre of photoconductive tube 13A, scatters to this optical centre tube wall on every side again, and the form with directional light is sent to ray machine 11B by photoconductive tube 13A at last.As shown in Figure 2, photoconductive tube 13A is positioned among the link block 13 and is to place along the optical axis 14 of light source 12A.In addition, base module 12 more can comprise a heat abstractor (not being shown among the figure), the heat that is produced in order to this light source of dissipation.
All applicable notion of the present invention of the projector of various types and embodiment, therefore, ray machine 11B can be a digital light and handles (digital light processing, DLP) pattern, a liquid crystal display (liquidcrystal display, LCD) pattern or a silicon liquid crystal (liquid crystal on silicon, the LCOS) ray machine of pattern.
As discussed previously, the extreme temperatures of the bulb of some projector inside when running.Because thermal convection has certain directivity, can play a role fully in order to make corresponding heat abstractor, most projectors all have the restriction of downward tilt, otherwise bulb may be because of overheated and break.In the present embodiment, the part of the main rotation of projector 10 is a camera lens module 11, and the light source 12A that is included in the base module 12 can remain on fixing position.Therefore, when the user changed the angle of projection image, the heat dissipating state of light source 12A can't be affected.By this, the user can indiscriminately ad. as one wishes adjust projection angle; The deviser also needn't take extra, complicated heat dissipation design for the anglec of rotation that cooperates camera lens module 11.
According to second preferred embodiment of the present invention also is the projector that comprises a camera lens module, a base module and a link block.This camera lens module comprises optical devices and a light source.These optical devices are in order to throw an optics message, and this light source system is in order to provide this optical devices light.This base module comprises one in order to the power supply unit of supply electric power to these optical devices and this light source.This link block is in order to connect this camera lens module and this base module, makes can to rotate relatively between this camera lens module and this base module.If needed, this camera lens module also can comprise a heat abstractor, the heat that is produced in order to this light source of dissipation.The main difference of the present embodiment and first preferred embodiment, be this light source be included in can camera lens module with respect to the rotation of this base module in.
Present embodiment is applicable to the lower situation of heat that light source produces.For example, adopt the LED bulb promptly to be applicable to the implementation of present embodiment as the projector of light source.Because the temperature the during running of LED bulb is lower, as long as suitable heat abstractor is arranged, the direction or the angle that change this light source can't cause too much influence to radiating efficiency.Therefore, this light source can be included in the camera lens module.The advantage of this embodiment be the rotatable direction of camera lens module necessary with this optical axis be coaxial.This projector can throw the direction and the angle of image and more enrich changeable.
Be compared to prior art, can be according to the camera lens of projector of the present invention by 360 degree rotations, to overcome the restriction on the space.For example, the user can be with according to the rotation of lens of projector of the present invention up, with image projecting on ceiling, and the appreciation film that cosily couching.Be compared to prior art, the present invention can select the place of projection image more neatly according to user's needs.
By the above detailed description of preferred embodiments, be to wish to know more to describe feature of the present invention and spirit, and be not to come category of the present invention is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain various changes and have in the category of claim of being arranged in of equality institute of the present invention desire application.
