Description
Technical field
The utility model is related to field of projector, more particularly to a kind of light-condensing array by concentrator as light source projects
Machine.
Background technology
Projecting apparatus, also known as projector are a kind of equipment that can be projected image or video on curtain, can be by not
The same computer of interface together, VCD, DVD, BD, game machine, DV etc., which are connected, plays corresponding vision signal.
Projecting apparatus is now widely used for family, office, school and public place of entertainment, according to working method difference, has
The different types such as CRT, LCD, DLP.
Projector is also applied to advertisement field at present, such as some advertisers project some publicity pictures on exterior wall,
It due to beautiful in colour, changes unpredictably, advertising results are fine, deep to be liked by vast advertising user.Become city together with neon light
A part for luxurious engineering.But CRT at present, the distance of the projector of LCD, DLP is all not far, generally 20 meters with
Inside there is preferable effect, people cannot be met to projecting remote requirement.
Utility model content
The utility model be directed to current CRT, the distance of the projector of LCD, DLP is all not far, generally 20 meters with
Inside there is preferable effect, people cannot be met to the deficiency of the remote requirement of projection, a kind of light-condensing array projector is provided, using poly-
Light device is projected, and projection distance is up to 200 meters.
The utility model is technical solution used by realizing its technical purpose：A kind of light-condensing array projector, including
One casing with projection window, generates the projection host of projection image, the superframe signal that the described projection host generates from
Window projects, and pattern is formed on projective object；The projection host includes an at least strut for being evenly equipped with concentrator,
The motor for driving strut to rotate around the shaft in casing further includes concentrator and motor on the control strut to form rotation
The control circuit board of persistence of vision light-condensing array screen.
The utility model provides the light-condensing array projector that a kind of projection distance is more than 200 meters.
Further, in above-mentioned light-condensing array projector：The cylinder side of the casing, the motor are
The DC brushless motor, the brush DC is fixedly mounted in DC brushless motor on the central shaft of cylindrical shell
Motor is fixed as the central tube of rotor with central shaft, as the cross bar for being fixedly connected with strut on the outer barrel of stator.
Further, in above-mentioned light-condensing array projector：The strut is four, is distributed on the central shaft four
In week, two are fixed four struts respectively perpendicular to the cross bar both ends of central shaft.
Further, in above-mentioned light-condensing array projector：In the cylindrical shell, it is horizontal to be vertically disposed with detection
Bar whether by infrared opposite-radiation pipe..
Below with reference to drawings and examples, the utility model is described in detail.
Description of the drawings
Fig. 1 is the light-condensing array projector front view of the utility model.
Fig. 2 is Figure 1A-A sectional views.
Specific implementation mode
The present embodiment is that (the i.e. persistancd of vision visions of POV are temporary similar to POV LED rotary screens for one kind
Stay) light-condensing array projector, it is similar to POV LED rotary screens, be distributed on strut 3 using the control of control panel circuit board
Concentrator and drive strut 3 rotate DC brushless motor 4 work form light-condensing array projector.Currently, using being evenly equipped with
The strut of LED rotates to form the technology that POV LED rotary screens are highly developed, it schemes one by one with common transverse scan formation
As cathode-ray tube, closer to LED display, currently, LED display is also transverse scan at scheming one by one
Picture, and it is the image one by one to form perpendicular scanning that the concentrator on the check 2 of conversion is used in the present embodiment, is needed
The picture signal of storage is handled before scanning, original lateral image is converted into longitudinal image.POV LED rotary screens
Projector be a kind of projector commonly used in the trade, only because the reason of brightness and the power of LED light therein, projection away from
From closer.
LED is substituted using colored concentrator in the present embodiment, as depicted in figs. 1 and 2, the light-condensing array of the present embodiment projects
Machine, including a casing 1 with projection window 2, casing 1 is in rounded shape, generates the projection host of projection image, projects host
The superframe signal of generation is projected from window 2, and pattern is formed on projective object；Colored concentrator is distributed on four struts 3,
Four struts 3 are connected by the cross bar 6 of two right-angled intersections, and a strut 2, general tie point are fixed in the both ends of every cross bar 6
Centre in the end of cross bar 6 and strut, is the central shaft 5 of cylindrical shell 1 at right-angled intersection, in the present embodiment, is driven
What cross bar 6 rotated is that the DC brushless motor 4 controlled by control circuit will be straight when using DC brushless motor in the present embodiment
Flow the central tube of brushless motor, that is, the rotor and cylindrical shell 1 of DC brushless motor said usually 5 weight of central shaft
It closes, for motor to be fixedly mounted, originally consolidates respectively with the cross bar 6 intersected of correcting a wrongly written character or a misspelt word as the outer barrel of the rotor of DC brushless motor
It is fixed, in this way, when DC brushless motor works, since original rotor secures, it cannot rotate, only original fixed stator
It rotates about the rotor, therefore, is rotated together with the stator of 6 fixed DC brushless motor 4 of cross bar.
In the present embodiment, when projection machine works, control circuit needs to know the position that each strut is currently located, it is known that
Behind each strut current location, so that it may to know when it reaches the corresponding position of window 2, currently, determining each strut（Optically focused
Lamp）There are many mode of the position at place, and using two to penetrating infrared tube in the present embodiment, on top, one is pacified for an installation
The bottom of mounted on, if the infrared ray in two is blocked, may determine that it is that cross bar blocks, in this way, control circuit can
To determine the position of strut.
