Abstract
The invention discloses a vertical ultra-short focus projector having a vertical housing and an optical projection system located within the housing. The projection lens of the optical projection system is located at a lower position of the housing and has a vertically upward irradiation direction. An aspheric reflector is disposed over the projection lens. A light outlet is arranged above the housing. The light emitted from the projection lens passes through the aspheric reflector and is emitted from the light outlet to be projected. Compared with the prior art, the vertical ultra-short focus projector achieves vertical placement, compact structure, ultra-short focus projection, can project things on a wall when getting close to or hanging on the wall, has a projection ratio of 0.2 and a projection ratio of 0.19, is suitable for narrow venues, temporary display, flexible needs, can be used for projection display in meetings, classrooms, public display spaces, art exhibitions, games, exhibitions, high-end commercial institution, and reception desks.
Description
Technical field
The invention belongs to projector's technical field, and in particular to a kind of vertical ultra short focal projector.
Background technology
Projector be it is a kind of can by the equipment on image or VIDEO PROJECTION to curtain, can by different interfaces with count
Calculation machine, VCD, DVD, BD, game machine, DV etc. are connected and play corresponding vision signal.Projector is widely used in family, office
Room, school and public place of entertainment, it is different according to working method, there are the different types such as CRT, LCD, DLP.It is newest in recent years go out LED
Projector allows projection industry development to a paramount field.But always one one-tenth not for the mode of delivery of existing projector
Become, just throw, lift, rear-projection, almost all of projector is all an appearance, projection screen is thrown front of the curtain for projector, needed
On desk to be placed on or on other placement platforms, personnel are easily impacted to projection, are not suitable with narrow and small environment and are used.
The content of the invention
To solve the defect that prior art is present, it is an object of the invention to provide a kind of vertical ultra short focal projector, real
Existing vertical placement, compact conformation, ultrashort out-of-focus projection can be projected in use on metope when can press close to or hang over metope.
For achieving the above object, the technical solution used in the present invention：The vertical ultra short focal projector, it is characterised in that：Tool
The projection lens for having vertical housing and the optical projection system in housing, the optical projection system is located at lower housing portion
Position, direction of illumination straight up, are provided with non-spherical reflector above projection lens, be provided with light and go out above housing
Mouthful, the light Jing non-spherical reflectors that projection lens is projected are projected by light outlet and are projected.
The surface of the projection lens inclines and is provided with plane mirror, and Jing planes are anti-successively for the light that projection lens is projected
Mirror and non-spherical reflector are penetrated, is projected by light outlet and is projected.
The non-spherical reflector is concave surface non-spherical reflector or convex aspheric surface speculum.
The light outlet is provided with dust cover.
The light source of the optical projection system is pure LASER Light Source, LED/light source, laser add phosphor source or laser to add
LED adds fluorescent material mixing light source.
The non-spherical reflector is 350mm apart from the distance of projection screen.
The aspherical face type of the non-spherical reflector：
Wherein, z is rise, and c represents the curvature of curved surface apex, r=x2+y2, k is circular cone coefficient, and x, y are represented perpendicular to optical axis
Coordinate surface quadrature component, a1、a2...a8Represent the corresponding coefficient of even order terms.
Using the beneficial effect of above-mentioned technical proposal：The vertical ultra short focal projector adopts vertical layout structure, and structure is tight
Gather.The projection lens of the optical projection system be located at lower housing portion position, direction of illumination straight up, in the upper of projection lens
Side is provided with non-spherical reflector, is provided with light outlet above housing, the light Jing non-spherical reflectors that projection lens is projected,
Projected by light outlet and projected.Realize that very-short-reach projects big picture, 70 cun of pictures can be thrown in 350mm distances（Diagonal）,
It is that short distance projects big picture, has broken people's thoughtcast conventional for projector, thoroughly excluded redundant space, greatly
The flexibility of projector's installation is increased greatly, can be hung on wall or be attached to wall side and project on wall.This original creation
Vertically displayed mode, has overturned use habit of the conventional people to projector, when breaching conventional projectors demonstration revolutionaryly
The series of problems such as the space that faced, shade, light interference, bring more hommization to multimedia teaching and business presentations
Using transformation.In actual mechanical process, use by hanging on metope, than reaching 0.2, projection ratio is 0.19, is adapted to for its projection
Narrow place, interim displaying, flexible and changeable demand, can be in meeting, classroom, common display space, exhibition of paintings, game, exhibition
Show, high-grade commercial undertaking, foreground etc. occasion carry out projection displaying, brand-new projection pattern can allow it almost can be any
Field is projected, and is supplied to the experience of user's more hommization.
The surface of the projection lens inclines and is provided with plane mirror, and Jing planes are anti-successively for the light that projection lens is projected
Mirror and concave surface non-spherical reflector are penetrated, is projected by light outlet and is projected to screen or metope.Using secondary reflection technology, light
After projection lens, Polaroid between projection lens and plane mirror, light is reflexed to offside by plane mirror
Top concave surface non-spherical reflector, light by concave surface non-spherical reflector reflect after, by the light outlet above housing
Reach second imaging of low coverage side screen.Two secondary reflections not only greatly shorten projector distance, form ultrashort burnt effect
Really, high definition, realizes giant-screen image projection, shortens 1/3 optical path length, obtains what ultra-high magnifications amplified using concavees lens
Reverse-engineer, projecting light path distance is reduced to into unprecedented degree, so as to reduce whole machine thickness and height, be close to metope or
Hung on a wall may be implemented in.
