Description
Technical field
The utility model relates to digital projection technique field, particularly, relates to the fibre optic image transmission projection lens for laser projection.
Background technology
Color Laser Projection Technology is to take the projection display technique that red, green, blue (RGB) tricolor laser is light source.Color Laser Projection Technology, because it enriches saturated color, high brightness, long-life, use cost is low and the characteristic such as energy-conserving and environment-protective, becomes the key factor that causes projection and display technique revolution.
Laser projection is to adopt advanced laser instrument as display light source, but because laser instrument can constantly produce heat in long-play process, the excess Temperature that heat accumulation causes will affect the normal work of laser instrument, so in order to make the long-time normal work of laser instrument, need to carry out temperature control to laser instrument.The LASER Light Source that high brightness laser projector is used is normally carried out temperature control by water cooling unit, but water cooling unit needs to carry out exchange heat with the external world in the course of the work, and can produce noise in the course of the work, therefore laser projection needs to consider its heat radiation requirement in installation process, the space of requirement placement laser projection is large and must carry out exchange heat with the external world.For example, the laser film projector using in movie theatre, needs projection room space larger, and will use air channel.
Utility model content
The utility model considers that the above-mentioned situation of prior art makes.
Fundamental purpose of the present utility model is, mainly for laser projection (and projector of other type), provide a kind of and can move flexibly, the projection lens of small size, to realize laser projection and projection lens separate design, can, according to the difference of environment for use, select flexibly the placement location of projector and the installation site of projection lens.
The basic ideas that the utility model solves its technical matters are: the image that adopts image rotation lenses that projector's internal transmission is gone out is coupled into optical fiber image transmission beam, through the image after optical fiber image transmission beam transmission, are amplified and are formed projected picture again by projection lens.
According to embodiment of the present utility model, a kind of fibre optic image transmission projection lens is provided, it is characterized in that comprising image rotation lenses (2), and optical fiber image transmission beam (3), wherein, the front end of described image rotation lenses (2) is over against the image light exit side of projector (1), described optical fiber image transmission beam (3) is disposed in the rear end of image rotation lenses (2), described optical fiber image transmission beam (3) is comprised of the corresponding optical fiber of the number of pixels of the image light with described projector (1), wherein, described image rotation lenses (2) is used for the corresponding optical fiber of the light coupled into optical fibres coherent fiber bundle (3) of each pixel of the image of projector (1) outgoing.
According to embodiment of the present utility model, the output terminal of described optical fiber image transmission beam (3), over against projection lens (4), is used for outgoing image equal proportion to be transferred to projection lens (4), to project curtain video picture.
The beneficial effects of the utility model are mainly: by the method for fibre optic image transmission, realize the transmission of projected image, transmission light path can extend and be flexible, therefore the needs according to occasion is installed, can carry out separated installation by laser projection and projection lens, projector is placed in external storage space, be convenient to heat radiation, operation and maintenance, projection lens can according to projected picture need to determine installation site, can guarantee the definitely quiet of playing environment.
Accompanying drawing explanation

Fig. 2 is the principle schematic of the optical fiber image transmission beam of embodiment of the present utility model.
In figure, description of reference numerals is as follows: 1, laser projection, 2, image rotation lenses, 3, optical fiber image transmission beam, 4, projection lens.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail, thus, advantage and disadvantage of the present utility model will be more clear along with description.
Although those skilled in the art will appreciate that the following description relates to a lot of ins and outs of relevant embodiment of the present utility model, this only illustrates that for being used for the example of principle of the present utility model does not mean that any restriction.The utility model can be applicable to be different from the occasion outside the following ins and outs that exemplify, as long as they do not deviate from principle of the present utility model and spirit.
In addition, for fear of the description that makes this instructions, be limited to miscellaneous, in description in this manual, may the processing such as omission, simplification, accommodation have been carried out to the part ins and outs that can obtain in prior art data, this is understandable for a person skilled in the art, and this can not affect the open adequacy of this instructions.
Fig. 1 is the figure of system layout of embodiment of the present utility model.
As shown in Figure 1, according to the fibre optic image transmission projection lens of embodiment of the present utility model, mainly comprise image rotation lenses 2, optical fiber image transmission beam 3.Image rotation lenses 2 is installed in the image light exit side of laser projection 1, image rotation lenses 2 can be coupled into the image equal proportion of laser projection 1 outgoing the input end of optical fiber image transmission beam 3,, by every optical fiber of the light coupled into optical fibres coherent fiber bundle 3 of each pixel, realize accurate point-to-point layout.Optical fiber image transmission beam 3 is transferred to projection lens 4 by output terminal by outgoing image equal proportion, to project curtain video picture.Optical fiber image transmission beam 3 can extend and can be crooked.As shown in Figure 2, the resolution of optical fiber image transmission beam 3 image resolution ratios of transmission and the outgoing image of former projection is consistent, that is, number of pixels is consistent.
In this example, laser projection can be positioned in independent machine room, is convenient to installation, operation and maintenance, and camera end can be placed in the correct position of playing before projected picture by optical fiber image transmission beam proper extension crooked, can guarantee that projection lens place noiselessness disturbs.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
