In conjunction with the accompanying drawings, photoelectricity voltage setter circuit theory of the present invention as shown in Figure 4, among the figure circuit by five the part form:
(A), by the Lights section of D1-D6, R13 and R14 built-up circuit.The main effect of this part is exactly to provide maximum light to circuit, and is concrete by regulating the resistance of R13 and R14, makes D1-D6 reach maximum light.
(B), the optical receiving circuit part of forming by R1-R11.R1-R5 is photoresistance in the circuit, has only two states in this circuit, is exactly the difference of bright resistance and resistance in the dark, is equivalent to a photoswitch, and the bright resistance of this resistance is 1K, and resistance in the dark is greater than 1M.R6-R10 in the circuit has formed a parallel circuit, and their resistance is very big, and is big to comparing with R1, can ignore R1.When the shadow shield in main shaft 51 and the linkage control device 52 is opened gradually, R1-R5 successively from resistance in the dark to bright resistance, R6-R11 forms resistor network and carries out output circuit, the intrinsic standoff ratio on the R11 changes gradually, forms the increase gradually of intrinsic standoff ratio.
(C), forming one by U2 penetrates with circuit.The effect that this circuit only has electric current to amplify, and input impedance is very big, and output impedance is very little, has increased the carrying load ability of circuit, and less to the resistor network dividing potential drop influence that R6-R11 forms, when the output voltage of resistor network changed, variation was followed in the output of U2.
(D), by the power unit of U1 built-up circuit.U1 is a three terminal regulator, changes U1, the output valve of promptly having regulated Vcc, and the size of regulating output voltage thus, this circuit can be regulated arbitrarily in the scope of 0-10V.
(E), form switch sections by K1.
The operate as normal of photoelectricity voltage setter of the present invention: the distance caging device in equipment combines with linkage control device, make cam control arm or pedal 55 on the main shaft 51 rotate an angle, the location coupling band 5 that drives on main shaft 51 and the main shaft 51 rotates an angle, the reed and the microswitch 4 that are fixed in the switch driving lever 54 of location coupling band 5 unclamp, circuit is through on-off circuit K1, U1 provides the stable interior adjustable voltage of 0-10V scope, simultaneously, shadow shield 52 rotates on the main shaft 51, the angle of light source irradiation on light source circuit board for receiving 2 is along with the rotation of shadow shield 52 is then changed from small to big, in the light source receiving circuit formed by R1-R11 in the light source circuit board for receiving 2 part R1-R5 successively from resistance in the dark to bright resistance, R6-R11 forms resistor network and carries out output circuit, intrinsic standoff ratio on the R11 changes gradually, form the increase gradually of intrinsic standoff ratio, only there is electric current to amplify by penetrating of forming of U2 with circuit, and import big impedance and the little impedance of output, increased the carrying load ability of circuit, less to the resistor network dividing potential drop influence that R6-R11 forms, when the output voltage of resistor network changes, variation is followed in the output of U2, thereby realizes controllable stable voltage output.
Below only be preferred embodiment of the present invention, according to above-mentioned design of the present invention, those skilled in the art also can make various modifications and conversion to this.For example locate that coupling band, light source circuit board for receiving, shadow shield, circuit of light sources plate etc. interconnect and the modification and the conversion of structure.Yet similar this conversion and modification all belong to essence of the present invention.
