Description
Technical field
The present invention relates to a kind of projecting apparatus, more particularly to a kind of color block module of projecting apparatus.
Background technology
The technology of DLP projector is a kind of full-digital reflective shadow casting technique.Its feature is Digital Advantage first.Digital skill
The use of art, improves gradation of image grade, and picture noise disappears, and image quality stabilization, digital picture is very accurate.Next to that
Reflection advantage.The application of reflective DMD device, greatly improves total light efficiency of image device, and contrast brightness uniformity is all
It is very outstanding.DLP projector definition is high, picture is uniform, and color is sharp keen, fine and smooth, naturally true to nature, and three machines can reach very high
Brightness, and can random zoom, adjust very convenient.
The operation principle of DLP projection arrangements is the illuminating bundle for being sent light source, by the colour wheel that rotates by light mistake
It is delivered to display module to be converted into image strip after filtering into three kinds of colors of red, green, blue, then is thrown image strip by projection lens
Shadow forms picture on screen, so that for spectator provides splendid visual effect.
Wherein, colour wheel be one kind can atwirl disk, can have the optical filter of various different colours thereon, it is such as red
Optical filter, green color filter and blue color filter, that is, red green blue tricolor are configured.Digital micro-mirror device need to coordinate red
The generation time of light, green glow and blue light and different states are presented, therefore, be that can accurately be projected out correct chromatic image,
Colour wheel is synchronous with digital micro-mirror device must effectively to be controlled, therefore the sensing of colour wheel relative position is just indispensable.Due to color
The rotation of wheel is realized by motor, therefore the rotation status of colour wheel are determined by the rotation status of motor shaft.It is many in colour wheel at present
Or time mark (Timing Index Mark, TIM) is attached on motor shaft, and this time is marked with optical sensor
Sensed, to judge the rotation status of motor shaft, the purpose synchronous with digital micro-mirror device so as to reach above-mentioned colour wheel.
But, attaching time mark there is also some problems, such as, time mark does not post contraposition causes sensor
Detecting electric voltage exception, so as to cause picture color to flash, serious results even in automatic shutdown.
Therefore, it is necessary to a kind of new projecting apparatus and its color block module are designed, to overcome drawbacks described above.

Continue referring to shown in Fig. 1 to Fig. 3, color block module 100 includes filter unit and rotating unit 10, the filter unit
It is connected with rotating unit 10, is rotated with the rotation with rotating unit 10.Rotating unit 10 includes first 101, second
102 and body 103, the filter unit is connected with the body 103, is rotated with the drive of body 103.It is used for for first 101
It is arranged on body 103, first 101 has the first outer surface 1010 and boss 1011, and boss 1011 protrudes the first outer surface
1010, and boss 1011 has the position mark, and the position mark is recognized in order to the sensing module.It is used for for second 102 solid
Due on body 103, have the second outer surface 1020 and an insertion for second 102 allows bit space 1021, allows bit space 1021 to use
It is engaged in boss 1011.For example, allowing bit space 1021 for perforate, but it is not limited.
Continue referring to shown in Fig. 1, first 101 and second 102 is fixed on body 103, preferably, first
101 are fixedly installed on body 103 by second 102, so that first 101 and second 102 with the rotation of body 103
And rotate, and when coordinating for first 101 and second 102, boss 1011 is located at and allows in bit space 1021, and the position mark
Expose, by allowing the positioning boss 1011 of bit space 1021, and then position the position mark, realize the accurate right of the position mark
Position.
Further, as shown in figure 1, when coordinating for first 101 and second 102, boss 1011 is located at and allows bit space
1021, and non-bulging second outer surface 1020 of boss 1011, preferably, boss 1011 is flushed with the second outer surface 1020, i.e., it is convex
3rd outer surface 10110 of platform 1011 flushes with the second outer surface 1020, with the counterweight of balanced rotating unit 10, improves and rotates single
The stability that unit 10 rotates, and boss is non-bulging allows bit space 1021, can reduce damage or collision and reduce the sensing module
The accuracy of sensing.
Further, the size and shape of bit space 1021 and the size and shape of boss 1011 is allowed to match, so as to allow
Bit space 1021 is accurately positioned the position of boss 1011, further improves the accurate contraposition of boss.
In practical application, the position mark is the 3rd outer surface 10110 of boss 1011, is filled referring in Fig. 1 and Fig. 3
The surface of point oblique line, the 3rd outer surface 10110 has the first reflectivity, and the second outer surface 1020 has the second reflectivity, and this
One reflectivity is different from second reflectivity, preferably, first reflectivity is less than second reflectivity, specifically by designer
Depending on according to actual conditions, will not be repeated here.In the present embodiment, the 3rd outer surface 10110 is obtained by way of spray painting, i.e.,
First reflectivity is realized in 3rd outer surface 10110 by spray painting mode, and this kind of spraying is difficult for drop-off compared with mounting method, risk compared with
It is low.In the present embodiment, the 3rd outer surface 10110 is black, but is not limited, specifically by designer according to actual conditions
It is fixed, will not be repeated here.
Further, as shown in figures 1 and 3, second 102 also has the first inner surface 1022, the first inner surface 1022
It is relative with the second outer surface 1020, bit space 1021 is allowed through the first inner surface 1022 and the second outer surface 1020, when first
101 and second 102 cooperate when, the first inner surface 1022 fits with the first outer surface 1020.
Further, first 101 is loop configuration, and the first outer surface 1010 is annular surface, and second 102 is annular
Structure, the second outer surface 1020 is annular surface, and the first inner surface 1022 is also annular surface.In the present embodiment, such as Fig. 1 to figure
Shown in 3, first 101 is annulus, and the first outer surface 1010 is the annular surface of closure, and second 102 is annulus, the second appearance
Face 1020 is the annular surface of closure, and the first inner surface 1022 is also the annular surface of closure, when first 101 and second
During 102 cooperation, second 102 is sheathed on first 101.
Further, for the ease of first 101 and second 102 assembling that cooperates, as shown in figure 3, allowing bit space
1021 have opening 1024 in first side 1023 of second 102, during assembling, first by the alignment boss 1011 of opening 1024, and
Moved along boss 1011, until boss 1011 is fully located at and allows bit space 1021.Wherein, the first side 1023 is second 102
Edge.Preferably, when boss 1011 is fully located at and allows bit space 1021, boss 1011 is flushed with the first side 1022.
Further, location structure is provided with second 102, location structure is used to be engaged with first 101, to limit
Fixed second 102 and first 101 relative position, prevents boss 1011 from deviating from from opening 1024.
To sum up, the present invention provides a kind of color block module, including rotating unit, the rotating unit include body, first and
Second, this first has the first outer surface and boss, and the boss protrudes first outer surface, and there is the boss position to mark
Note, this second bit space that allows with the second outer surface and insertion, when coordinating with this second for this first, boss position
Allow bit space, and the position mark to expose in this, with by the resigning space orientation boss, and then position the position mark,
Realize the accurate contraposition of the position mark, it is to avoid the detecting electric voltage exception of sensor, cause automatic shutdown or picture color to dodge
It is bright.The present invention is been described by by above-mentioned related embodiment, but above-described embodiment is only to implement example of the invention.Must refer to
