Under control stick pushbutton operating modes, first by regulating S1 control D1 to carry out eye focusing to a certain brightness, during shooting, press lower control arm button K1, PC and CPU receive orders simultaneously, PC sends shooting order to camera, camera exposure, simultaneously CPU control D1 maximum luminance.
Under PC interface operation pattern, first by regulating S1 controls D1 to carry out eye focusing to a certain brightness, during shooting, clicking software shooting on PC and ordering, camera receives orders while exposure and sends synchronizing signal to CPU, CPU control D1 maximum luminance.
Under camera shutter operator scheme, first by regulating S1 control D1 to carry out eye focusing to a certain brightness, during shooting, press the shutter K2 on camera, camera in exposure simultaneously, exports synchronizing signal to the CPU of controller, CPU control D1 maximum luminance.
Under each operator scheme, during shooting image, the high-high brightness persistent period of D1 is identical with the camera exposure time.After picture shooting is complete, CPU control D1 luminance recovery is to the brightness regulated during preview image.
The present invention compared with prior art has significant advantage and beneficial effect, is embodied in the following aspects:
Present invention achieves and slit lamp light source can be adjusted to the state making person under inspection's eyes feel comfortable when focusing, control by adopting camera synchronization flash of light, the brightness controlling light source when exposure image reaches maximum, makes shooting image out more clear, optimizes the quality of shooting image.
The image that the slit lamp microscope of the design is taken out does not vary with each individual, and greatly reduces eyes image and gathers difficulty, and improve checking efficiency.
Accompanying drawing explanation
Fig. 1 is slit lamp microscope light-source control system structure chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in Figure 1: 1 is power supply, 2 is power supply adaptors, and 3 is Power convert, and 4 is CPU, and 5 is that constant-current source drives, and 6 is brightness regulation knobs, and 7 is control stick buttons, and 8 is LED light sources, and 9 is camera shutters, and 10 is cameras, and 11 is PCs.
A kind of slit lamp microscope light-source control system of this implementation column, comprise power supply 1, LED light source 8, CPU4, brightness regulation knob 6, camera 10, PC 11, LED light source 8, PC 11, camera 10, brightness regulation knob S1 are connected with CPU4, CPU4 can control the brightness of LED light source 8 by output pwm signal, regulate the brightness of brightness regulation knob 6 scalable LED light source 8, camera 10 is connected with PC 11, is connected to control stick button 7 between PC 11 and CPU4.
What this implementation column adopted is the input of 110-220V Width funtion power supply, exports 12VDC voltage to main circuit board by power supply adaptor 2, comprises Power convert 3, LED constant current source driving 5, CPU4 and various external signal input interfaces etc.Wherein 12VDC Power convert becomes 5VDC to power to CPU4 by Power convert 3.Constant-current source drives 5 then to adopt 12VDC directly to power.Control and algorithm all complete in CPU4.This light-source control system has three kinds of trigging control patterns.
