Fig. 3 is the schematic diagram of the colour wheel module of second embodiment of the invention.
Fig. 4 and Fig. 5 are respectively the colour wheel module of third embodiment of the invention at the schematic diagram of different visual angles.
Embodiment
Refer to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are respectively the colour wheel module 10 of first embodiment of the invention at the schematic diagram of different visual angles.Colour wheel module 10 is applied in projector, to carry out separation and the processing to different color.Colour wheel module 10 comprises colour wheel unit 12 and reflector 14.Colour wheel unit 12 is made up of filter 16 and driver element 18.Filter 16 can be the basic three colour wheel technology that contain redness (R), green (G), blue (B), the six colour wheel technology that also can increase the middle transition colors such as transparent (W), yellowish (Y), bluish-green (C) on three primary colors basis newly, are so not limited to this.Driver element 18 can be rotation motor, is connected in filter 16 to drive the High Rotation Speed of filter 16.The light signal in predetermined wavelength range can be reflected in reflector 14, is used for being used as the time index label of colour wheel module 10.Reflector 14 is coated on the outer surface of driver element 18.
As shown in Figures 1 and 2, colour wheel module 10 also comprises signal transceiver 20, is positioned at colour wheel unit 12 other.The sense terminal of signal transceiver 20 points to driver element 18.Signal transceiver 20 can produce light wave signal or sound wave signal etc.In general, the color coefficients of the outer surface of driver element 18 is different from the color coefficients in reflector 14, and the wave-length coverage of the first signal of exporting of signal transceiver 20 is in reflector 14 can aitiogenic predetermined wavelength range.Therefore, in the time that filter 16 rotates, signal transceiver 20 continues to send the first signal, and the outer surface that the first signal is irradiated to driver element 18 can not reflect, and the first signal is irradiated to 14, reflector can be reflected corresponding the second signal of generation.The direct of travel essence of the second signal is in contrast to the direct of travel of the first signal, and signal transceiver 20 receives after the second signal, just can judge accordingly the parameter such as rotating cycle, turned position of colour wheel unit 12, to learn rotating speed and the corner of filter 16.
In the first embodiment, certain material is selected in reflector 14, and is coated on the outer surface of driver element 18 in modes such as paint or printings.The predetermined wavelength range in reflector 14 can be designed to infrared band, visible light wave range, ultraviolet wave band etc., and its application is looked closely actual demand and determined, in this explanation in detail no longer respectively.Reflector 14 is can be coated with kenel time, can utilize the toughness in reflector 14 to increase the bond strength of reflector 14 and driver element 18.In addition, volume that can coating reflection layer 14 is conventionally less, is only thin layer, is difficult for coming off because of windage or gravitational effect, therefore colour wheel module 10 of the present invention has preferably use reliability in the time of driver element 18 High Rotation Speed.
Refer to Fig. 3, the schematic diagram of the colour wheel module 30 that Fig. 3 is second embodiment of the invention.Colour wheel module 30 comprises colour wheel unit 32 and reflector 34.Colour wheel unit 32 comprises filter 36 and driver element 38.The structure of filter 36 forms the filter 16 of similar the first embodiment, in this no longer repeat specification.Driver element 38 is connected in filter 36 to drive filter 36 to rotate.Driver element 38 comprises housing 381 and supporting part 383, and supporting part 383 can form the ad-hoc location at housing 381 highlightedly or hollowly.Reflector 34 is thin-film component or block elements, is embedded in supporting part 383.Reflector 34 can be used to reflect the light signal in predetermined wavelength range.
Refer to Fig. 4 and Fig. 5, Fig. 4 and Fig. 5 are respectively the colour wheel module 50 of third embodiment of the invention at the schematic diagram of different visual angles.Colour wheel module 50 comprises colour wheel unit 52 and optical detector 54.Colour wheel unit 52 comprises filter 56 and driver element 58.Driver element 58 is connected in filter 56 to drive the rotation of filter 56.Filter 56 comprises multiple filter units 60, and the wave band of allowing that each filter unit 60 is different because heterochromia has respectively, as the related description of the first embodiment.Optical detector 54 is positioned at 52 sides, colour wheel unit and points to filter 56.The induction wave band of optical detector 54 only limit to correspond to filter 56 one of them filter unit 60 allow wave band.Colour wheel module 50 separately comprises light source 62, is arranged on a side of colour wheel unit 52 relative optical detectors 54.
As shown in Figure 5,54 points of light source 62 and optical detectors are located at the two opposite sides of filter 56, and the light signal that light source 62 is exported need just can be detected and receive by optical detector 54 by filter 56.As a rule, light source 62 can be white light source, and meaning is the different color that light signal that light source 62 is exported comprises various wave bands.The position of optical detector 54 maintains static.If optical detector 54 is infrared light detector, only have in the time that filter 56 rotates to its red filter unit 60 and is aligned in the angle of optical detector 54, optical detector 54 could receive the penetrating light signal (penetrating the ruddiness signal of filter 56) from light source 62; When the filter unit 60 alignment light detector 54 of other color of filter 56, the light signal that penetrates filter 56 does not meet the sensing wave band of optical detector 54, not effect of optical detector 54.Thus, optical detector 54 can judge the position of specific color filter unit 60 by this, and then learns rotating speed and the corner of filter 56.
In sum, the first embodiment of the present invention and the second embodiment utilize coating and chimeric mode that reflector is arranged on driver element, avoid reflector to separate under High Rotation Speed with driver element; The third embodiment of the present invention is given up the application in reflector, selects its induction wave band to read the penetrating light by filter corresponding to the optical detector of specific color (specific allow wave band) filter unit.Compare the prior art that with manual type, reflector is sticked on to driver element, the viscose glue that the present invention can effectively improve traditional reflective layer holds caducous shortcoming, improves the use reliability of colour wheel module.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the claims in the present invention change and modify, and all should belong to covering scope of the present invention.
