Yet; known projection arrangement in use is difficult to detect the operation conditions of micro electronmechanical eyeglass; especially when micro electronmechanical eyeglass can't be swung and rest on middle position; laser can't become sweep trace or scan face by the swing of micro electronmechanical eyeglass; at this moment; laser will and pool pencil perpendicular to cover glass incident; and the high power laser light of this output is radiated at the generation that causes the fire or the accident of burning on fire goods or the human body easily for a long time, so be necessary to research and develop a kind of projection arrangement that can be used for detecting micro electronmechanical eyeglass operation conditions at the defective of the known projection arrangement of this kind.
The utility model content
Thereby the purpose of this utility model is to provide a kind of be can be used for detecting micro electronmechanical eyeglass operation conditions and can prevent the projection arrangement that has an accident.
For achieving the above object, projection arrangement provided by the utility model comprises a LASER Light Source, a LASER Light Source driver, a micro electronmechanical eyeglass, a micro electronmechanical eyeglass driver, a cover glass, a signal detection device and a controller.The LASER Light Source driver is in order to the driving laser light source, and the micro electronmechanical eyeglass that can swing is in order to the laser of accepting LASER Light Source and send, and micro electronmechanical eyeglass driver is in order to drive micro electronmechanical eyeglass, and cover glass is accepted laser and the output that micro electronmechanical eyeglass is sent; The signal detection device is in order to accepting through the cover glass laser light reflected and to generate feedback signal, and controller is accepted feedback signal and controlled the LASER Light Source driver and micro electronmechanical eyeglass driver.
In sum, projection arrangement provided by the utility model is by the setting of signal detection device, can detect the operation conditions of micro electronmechanical eyeglass, thereby can avoid shining the fire failure that causes on fire goods or the human body for a long time or burning because of micro electronmechanical eyeglass causes high-power laser when motionless.

Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, the utility model projection arrangement 100 comprises a controller 10, a LASER Light Source 20, a LASER Light Source driver 30, one micro electronmechanical eyeglass 40, one micro electronmechanical eyeglass driver 50, a cover glass 60 and a signal detection device 70.
Please continue and consult Fig. 1, the controller 10 of the utility model projection arrangement 100 is in order to control LASER Light Source driver 30 and micro electronmechanical eyeglass driver 50.Described micro electronmechanical eyeglass driver 50 is in order to drive micro electronmechanical eyeglass 40, and LASER Light Source driver 30 generates laser in order to driving laser light source 20.When projection arrangement 100 is in unlatching or self check state, controller 10 sends the corresponding driving signal to micro electronmechanical eyeglass driver 50 and LASER Light Source driver 30 respectively, and micro electronmechanical eyeglass driver 50 receives the micro electronmechanical eyeglass 40 of corresponding driving signal rear drive and makes micro electronmechanical eyeglass 40 reciprocally swinging back and forth.Controller 10 sends the corresponding synchronous drive signal to LASER Light Source driver 30 simultaneously and makes LASER Light Source driver 30 driving laser light sources 20 generate laser.The laser projections that LASER Light Source 20 generates is on the micro electronmechanical eyeglass 40 of reciprocally swinging.
In the utility model, by the continuous swing of micro electronmechanical eyeglass 40, the laser of incident will be sent and be incident upon on the cover glass 60 by micro electronmechanical eyeglass 40 in the mode of sweep trace or scanning plane.Wherein a part of laser passes cover glass 60 and is projected on the (not shown) of projecting plane and then generates corresponding image.Another part laser is by cover glass 60 reflections; the zone definitions that the reflected light of described cover glass 60 can reach is a reflector space; and when micro electronmechanical eyeglass 40 is rocked to the extreme position corresponding with signal detection device 70; when being the marginal position of signal detection device 70 reflector space that is arranged on cover glass 60, can receive and generate corresponding feedback signal by signal detection device 70.The feedback signal of being exported is received by controller 10, and judge and the signals of exporting micro electronmechanical eyeglass 40 normal operations are given the display unit (not shown) by controller 10, can make operating personnel learn that projector equipment is in the situation of normal operation and does next step relevant operation thus.
In the utility model, when micro electronmechanical eyeglass 40 is not worked and when resting on middle position or swing not in place and can't make signal detection device 70 receive these part laser the time, judge and export the abnormal signal of micro electronmechanical eyeglass 40 operations and give the display unit (not shown) by controller 10, can make operating personnel know that projector equipment is in the situation of irregular operating and makes next step associative operation by this.From the above; micro electronmechanical eyeglass 40 is in order to the laser that receives LASER Light Source 20 and send; cover glass 60 is in order to the laser that receives micro electronmechanical eyeglass 40 and send and send, and signal detection device 70 is in order to accept generating different feedback signals through cover glass 60 laser light reflected and according to the laser input status.
