Description
Technical field
The invention belongs to projection art, more particularly to a kind of micro projector.
Background technology
As the explosion type of Intelligent mobile equipment develops, personal portable office, the demand entertained are more and more high, and people increasingly feel cell-phone function contradiction little with screen by force；The highly desirable energy micro projection of user is interconnected with mobile phone, amplifies mobile phone screen or independent use.Video device external at present is mainly traditional mercury lamp formula projecting apparatus or irremovable other multi-media display devices for using.The characteristics of this 2 kinds of equipment, can not meet people in mobile office, personal entertainment and the convenient demand for using, while also bringing many problems.For example：
Using the shortcoming of traditional mercury lamp formula projecting apparatus：
Service life is short.The life-span of bulb is averagely at 2000 hours；Calculated with family expenses（Daily 5 hours）, more to be changed the bulb using 1.5 years.The expense for more changing the bulb is sufficiently expensive（Average 1000 yuan）.
Power consumption is big, noise is big, radiation is big.Conventional projector average power consumption more than 260 watts, need 4 fans, noises it is very big, while there is radiation；Very inapplicable family.
Brightness is too high.Conventional projector typically above 2000 lumens, comparison of seeing a film at home are dazzling.
Color representation power is weak.Conventional projector colour gamut is very narrow, and colorfulness and level are undesirable.
Using single function.
The shortcoming of other multi-media display devices：
Volume is larger.Stock size is considerably beyond common external equipment volume.
Connectivity is poor, needs cable connect.The connection of personal mobile device can not be supported convenient.
Mobility is poor, and other display equipment is required for external power supply to use, and cannot use where some do not have power supply supply.
In addition, existing projecting apparatus generally needs manual focus, focus operation trouble, using inconvenience.
The content of the invention
In view of this, it is an object of the invention to provide a kind of projector of auto-focusing, can auto-focusing, it is easy to operate.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
The invention belongs to projection art, more particularly to a kind of micro projector；
The projector of auto-focusing, including ultrasonic transceiver module, light source, light path system, Digital Micromirror System, control system and power module, the light source is LED/light source；The control system includes processor circuit, digital picture drive circuit and interface circuit, the signal output part of the interface circuit is electrically connected with the signal input part of processor circuit, the signal input part of digital picture drive circuit is electrically connected with the signal output part of processor circuit, the signal input part of the light source and Digital Micromirror System is electrically connected with the signal output part of digital picture drive circuit, the power module is light source, light path system, Digital Micromirror System and control system are powered, the light path system includes camera lens, the signal port of the ultrasonic transceiver module is electrically connected with the signal port of processor circuit, the control port of the focusing motor of the camera lens is electrically connected with the control port of processor circuit.
Further, the power module includes battery and civil power AM access module.
Further, the interface circuit includes WIFI module, HDMI, USB interface and decoding circuit.
Further, the processor model is quad core Cortex-A9.
Further, also including memory module, the memory module includes eMMC memories and micro SD interfaces, and the FPDP of memory module is electrically connected with the FPDP of processor.
Compared with prior art, the invention has the advantages that：
1st, as using new LED/light source, direct beneficial effect is to greatly improve service life（The life-span of LED/light source is more than 20000 hours）, family's use time was up to 15 years；It is ten times of traditional mercury lamp formula projecting apparatus.Novel LED light source is used in addition, and, equivalent to bulb or the 1/8-1/10 of large-screen receiver, environmental protection and energy-saving effect are notable for its power consumption.The colour gamut of LED/light source is far longer than bulb and liquid crystal simultaneously；Therefore conventional projector and other display equipment are much better than to the expressive force of color.
2nd, due to using digital micro-mirror imaging system, maintaining all of light of source images and subtlety, the reducing power of image is greatly enhanced, the level of movie theatre level can be reached；Second definition for being capable of maximized utilization LED/light source and maximized holding image using Digital Micromirror System.Therefore, the image effect that user sees is far superior to legacy equipment.
3rd, the design of internal battery has been used, use after charging, can have been moved.
4th, with ultrasonic transceiver module, processor can carry out auto-focusing by ultrasound examination projector distance, the focusing motor for then controlling camera lens.
