Abstract

The utility model relates to a color wheel fixing structure which is mainly provided with color wheels formed by the combination of a plurality of optical filters in a binding mode. A fixed ring is utilized to be fixed at the circumference on the outer side of the optical filters in an up or down mode in order to prevent the phenomenon that the optical filters under the state of quick rotation in high temperature are disengaged and separated from each other and can not tightly adhere to each other.

Description

The colour wheel fixed sturcture

Technical field

The utility model relates to the optical element of projector equipment, refers to a kind of interior colour wheel fixed sturcture as optical filtering usefulness of projector equipment of being located at especially.

Background technology

The technology of projector can be divided into iconoscope (CRT) type, liquid crystal (LCD) type and digital light device (DLP) and miniscope.And existing digital light device architecture as shown in Figure 1, after wherein this light source 1 penetrates by the high brightness bulb, by a colour wheel 2 (Color Wheel) light is divided into red (R), green (G), blue (B) three looks, reach full-color effect in view of the above, and light is evenly distributed by a condenser system 3, again with color by lens 4 be imaged on digital micro-analysis lens device 5 (Digital Micro-Mirror Device, DMD) on, projection imaging on camera lens 6 more at last.

It should be noted that, can directly influence the color quality of projection image because of the structural quality of this colour wheel 2, as shown in Figure 2, be existing colour wheel structural representation, this colour wheel 2 comprises that a disc carrier 8 and with flange 7 has the filter set 9 of center pit, and after its surperficial 8A in this disc carrier 8 went up the glutinous agent of coating one deck, the center pit with filter set 9 was inserted in the flange 7 again, filter set 9 is attached on the surperficial 8A of disc carrier 8, to form this colour wheel 2 by glutinous agent.

This filter set 9 also utilizes viscose glutinous establishing adjacent one another are to form by several pieces optical filters 9A again, this colour wheel 2 can produce high speed rotating and high temperature when filtering, so coating the viscose of this several optical filter 9A joint has dissolution phenomena and causes gap 9B to produce, as shown in Figure 3, and normally begin to break away from, separate, slowly extend expansion again to the center by optical filter 9A outside joint.In case when the optical filter 9A of this filter set 9 can't combine closely, the color quality of this colour wheel 2 image that throws is affected.

The utility model designer can't combine closely under the high temperature fast rotational in view of the filter set 9 of existing colour wheel 2, cause influencing the situation of the color quality that throws image, by feat of the experience of being engaged in relevant industries for many years, concentrate on studies, improved and constantly test feasible, initiate out colour wheel fixed sturcture of the present utility model.

The utility model content

Fundamental purpose of the present utility model is to provide a kind of colour wheel fixed sturcture, and it sets firmly with the upper and lower formula by a set collar in several optical filter outboard peripheries, makes it avoid this optical filter to produce the phenomenon of disengaging, division under the high temperature fast rotational.

The technical scheme that relevant the utility model is adopted for achieving the above object, existing conjunction with figs. is described as follows.

Description of drawings

Fig. 1 is existing digital light device architecture figure.

Fig. 2 is existing colour wheel schematic perspective view.

Fig. 3 uses synoptic diagram for existing colour wheel.

Fig. 4 is the utility model three-dimensional exploded view.

Fig. 5 is the utility model three-dimensional combination figure.

Fig. 6 is the utility model assembled sectional view.

Embodiment

At first, be the utility model three-dimensional exploded view referring to Fig. 4.As shown in the figure: the utility model is the colour wheel fixed sturcture, this colour wheel 10 mainly includes: a disc carrier 11 and a filter set 20 stick to establish and form, wherein this filter set 20 includes several pieces optical filters that is fan-shaped 21, the both side edges 210 of these several pieces optical filters 21 is coated with the viscose material, these several pieces optical filters 21 is binded to form a filter set 20 again.

In addition, have a set collar 30, this set collar 30 is respectively equipped with a base ring 31 and a bezel ring, 32, and wherein this base ring 31 has a tank 310.

During combination,, be respectively the utility model three-dimensional combination figure and assembled sectional view referring to Fig. 5 and shown in Figure 6.Filter set 20 is positioned on the tank 310 of base ring 31 of this set collar 30, utilize bezel ring, 32 to be covered on the base ring 31, and tightly suppress this optical filter 21 outboard peripheries, and make the outboard peripheries of this optical filter 21 ring 30 that is fixed coat and combine closely, this is technical characterictic of the present utility model place.

In view of the above, when colour wheel 10 of the present utility model under the high temperature fast rotational, fix this optical filter 21 outboard peripheries by this set collar 30, break away from, separately to prevent that optical filter 21 from can be begun to produce by outside joint.

In other words, though colour wheel of the present utility model 10 under the high temperature fast rotational, these several pieces optical filters 21 also can form tight bonding shape, to avoid causing the projection bad of light source.

The above, it only is preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with it, promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
