Light emitting source 4 is electrically connected by illuminated push button 1 and 1.5 volts of power supplys；
First photo resistance 6 and the second photo resistance 7 are connected in series with 1.5 volts of power supplys, also, the first photo resistance 6 and
Two photo resistance, 7 model is consistent；
The input terminal of illuminating circuit is connected between the first photo resistance 6 and the second photo resistance 7.
The illuminating circuit includes triode 14, LED light 5, power on buttons 2 and power supply source；The base stage of triode 14 connects
Between the first photo resistance and the second photo resistance, the collector of triode 14 connects LED light 5, LED light 5 by power on by
Button 2 connects the anode of power supply source, and the cathode of power supply source is connected to the emitter of triode 14.
The base stage of triode 14 is connected between the first photo resistance 6 and the second photo resistance 7, on the collector of triode
Power supply source is connected equipped with LED light 5, and by power on buttons, power supply source voltage is preferably 9 volts.
The triode 14 uses conducting voltage for the triode of 0.7V, the first photo resistance 6 and the second photo resistance 7
Resistance value is more than R1 resistance values so that when not opening illuminated push button 1, the voltage value in the second photo resistance 7 is in close and leads device
Logical state, preferably 0.6V.
In other embodiments of the invention, three poles that conducting voltage is 0.5V or other values can be used in the triode 14
Pipe 14, but power supply need to do corresponding adjustment.
In other some embodiments of the present invention, the resistance value of the first photo resistance 6 and the second photo resistance 7 can be chosen
Prodigious value so that the electric current very little that power supply 4 circulates extends the service life of power supply 4, can take multiple triodes 14 at this time
It is combined so that LED light 5 obtains sufficiently large glow current.
In certain embodiments of the present invention, field-effect tube may be used and substitute triode 14.
By driving the conducting of triode 14 and ending the wink to realize the break-make of illuminating circuit, then turned off in triode 14
Between triode collector generate instantaneous pressure, triode 14 is damaged.
Zener diode 15 is connected between the collector and emitter of triode 14, zener diode 15 may make three poles
Pipe works in the voltage range of safety, extends the service life of device.
Illuminated push button 1, power on buttons 2, Amici prism 3, light emitting source 4, LED light 5, the first photo resistance 6, the second photosensitive electricity
Resistance 7, triode 14 and zener diode 15 are all encapsulated in tie-beam 11 and light beam 12.
Amici prism 3 is arranged in 4 face of light emitting source, and the one side face light-emitting window 8 of Amici prism 3 separately has one side face first
Photo resistance 6；
Tie-beam 11 is additionally provided with light inlet 9 on one side equipped with light-emitting window 8, and light inlet 9 faces the second photo resistance 7.
One end of tie-beam 11 connects latch closure 10, and the other end connects light beam 12.
The side opposite with light-emitting window 8 of light beam 12 is equipped with acrylic board 13,13 times face LED light 5 of acrylic board.
Illuminated push button 1, power on buttons 2 are set to the both sides of light beam 12.
The thickness of tie-beam 11 is less than the thickness of light beam 12 and latch closure 10, and the consistency of thickness of light beam 12 and latch closure 10.
Incident collimated light beam is divided into the first equal divided beams and second the first divided beams of divided beams by Amici prism 3,
First divided beams invests the first photo resistance 6, and the second divided beams invests minute surface to be measured by light-emitting window 8, through mirror-reflection to be measured
Afterwards the second photo resistance 7 is invested from light inlet 9.
6 and second light of corresponding first photo resistance can be completely covered with the projection scope of the second divided beams in first divided beams
Quick resistance 7；Projectional angle folded by first divided beams and the first photo resistance 6 is equal to second the second photo resistance of divided beams administration 7
Projectional angle.
Operation principle：
In use, first pressing illuminated push button 1, light emitting source 4 will generate collimated light beam, and collimated light beam will by Amici prism 3
It is divided into equal the first divided beams and the second divided beams, wherein the first divided beams invests the first photo resistance 6, the second divided beams is logical
Cross the injection of light-emitting window 8；Power on buttons 2 is pressed again, and light beam does not work at this time；Finally, device is had to the side of light-emitting window 8 and mirror to be measured
Face paste is closed, and whether observation light beam 12 is bright.
If minute surface to be measured is plane mirror, the front and back light intensity of plane mirror reflection is equal, so, the first photo resistance 6 and second
Photo resistance 7 receives ground intensity of illumination and is consistent；Since the first photo resistance 6 is consistent with 7 model of the second photo resistance,
Voltage in first photo resistance 6 and the second photo resistance 7 is equal, at this point, triode is in cut-off state, LED light 5 is not
It is bright；
If minute surface to be measured is single plane fluoroscopy mirror, the second divided beams will have segment beam that will pass through single plane fluoroscopy mirror, remaining
Part then reflexes to the second photo resistance 7；Therefore, the second photo resistance 7 reception ground intensity of illumination is less than the first photo resistance 6,
The voltage that the resistance value of second photo resistance 7 will be above in 6 second photo resistance 7 of the first photo resistance also will be above the first photosensitive electricity
Resistance 6, at this point, triode is in the conduction state, LED light 5 is lighted.
For based on the improvement made on the basis of the present invention, protection scope of the present invention being fallen within, all the present invention's
In protection domain；Although the present invention, ability has shown and described with reference to certain exemplary embodiments of the present invention
Field technique personnel will be understood that, can carry out various changes of form and details wherein, the spirit without being detached from the present invention
And range, the spirit and scope of the present invention such as the appended claims limit.
