Description
Technical field
The utility model relates to a kind of projector, particularly relates to Minitype digital projector.
Background technology
Projector be a kind of by optical principle by the image projection that is shown in the small screen to the machine on curtain, its many be applied to by business people the place such as product demonstration and various congress introduction, and family often uses projector to be used for amusement.Conventional projector volume is all at about 30cm*10cm*20cm, its reason weight because of element in machine mostly is about 2-3 kilogram, be not easy to carry in real life, and also have small projector on the market but cause projection quality not high and some focal length is long because of the reason of light source, power consumption is excessive, continues use ability not remarkable.
Summary of the invention
The utility model discloses Minitype digital projector, bulky in order to solve existing projector, not portable, micro projector projection quality is not high, the long and shortcoming that power consumption is excessive of focal length.
Technical solution of the present utility model is:
A kind of Minitype digital projector, comprise light-source system, projection objective, it is characterized in that: described light-source system is by green LED group, red and blue LED lamp group, light collection system and polarizing filter synthesis system composition, angle degree of being between green LED group and red and blue LED lamp group, light collection system is arranged at green LED group and red and blue LED lamp group front end respectively, polarizing filter synthesis system is arranged between green LED group and red and blue LED lamp group, arrange below light-source system by microlens array, the parellel light beam system of convex lens and catoptron composition, parellel light beam system light injection direction is arranged by prism, the imaging system of TIR prism and digital micro-mirror chip composition, projection objective is provided with above imaging system.
Described projection objective is four group of five chip projection objective, and projection objective is other is provided with focus adjustment knob.
The beneficial effects of the utility model are: use efficient LED light source, and the life-span is long and low in energy consumption, use the optical system of multiple light courcess, eyeglass composition, light loss benefit is little, and efficiency is high, and focal length is short, use digital micro-mirror chip to connect easily, and little being easy to carry about with one of volume is particularly useful for business system.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
See accompanying drawing, the utility model comprises light-source system 1, projection objective 16, it is characterized in that: described light-source system 1 is by green LED group 11, red and blue LED lamp group 12, light collection system 13 and polarizing filter synthesis system 111 form, between green LED group 11 and red and blue LED lamp group 12, angle is 90 degree, light collection system 13 is arranged at green LED group 11 and red and blue LED lamp group 12 front end respectively, polarizing filter synthesis system 111 is arranged between green LED group 11 and red and blue LED lamp group 12, arrange below light-source system 1 by microlens array 141, the parellel light beam system 14 that convex lens 142 and catoptron 143 form, parellel light beam system 14 light injection direction is arranged by prism 151, the imaging system 15 that TIR prism 152 and digital micro-mirror chip 153 form, projection objective 16 is provided with above imaging system 15.
Described projection objective 16 is four group of five chip projection objective, and projection objective 16 is other is provided with focus adjustment knob 17.
To use mobile phone to be connected with Minitype digital projector, when reality uses, opening power, is connected mobile phone with Minitype digital projector by bluetooth, and mobile phone is started and digital micro-mirror chip signal transmission by bluetooth.Green LED group 11 in light-source system and red and blue LED lamp group 12 start luminescence, light invests polarizing filter synthesis system 111 by light collection system 13, green beam is through polarizing filter synthesis system 111 directive micro mirror array 141, red blue beam reflects to micro mirror array 141 by polarizing filter synthesis system 111, light beam is converted to directional light through after micro mirror array system 141 through convex lens 142, and imaging system 15 is invested under catoptron 143 reflects, the Images uniting transmitted with the digital micro-mirror chip 153 showing image by Bluetooth transmission in TIR prism 152 by the refraction of prism 151 in reflecting system reflects imaging system 15, image is projected on screen by the projection objective 16 regulating focus adjustment knob 17.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; the any of other does not deviate from the technical solution of the utility model and the substitute mode of the change made or other equivalence, is all included within protection domain of the present utility model.
