It is low, it is able to solve optical illumination gun sight gear and ambient light matching problem.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the bright gun sight overall structure diagram of automatic illumination in the utility model embodiment；
Fig. 2 is lighting system partial structural diagram in the utility model embodiment.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
In the utility model embodiment, as shown in Figure 1 and Figure 2, including gun sight ontology and lighting system, optical illumination system
System includes solar panel 41, chargeable button cell 42, light-operated circuit plate 43, photodiode 2, light emitting diode 6, automatically
Optical illumination gun sight is installed on gun guide rail, and photodiode is for sensing extraneous light intensity, when extraneous light intensity signal value is greater than
When starting setting value, light emitting diode starting, solar panel absorbs solar energy in illumination and charges for chargeable button cell,
When the extraneous light intensity signal value of photodiode acquisition is greater than starting setting value, light-operated circuit plate opens lighting system 4, can fill
Electric button cell is the power supply of light-operated circuit plate.Gun sight ontology includes eyepiece 1, image rotation lenses system 3, object lens 5.Photodiode
The illumination of suffered external environmental light is converted into corresponding signal value, handles signal value by circuit control chip.When the external world of acquisition
When light intensity signal value is less than starting setting value, it is not turned on lighting system；When greater than starting setting value, lighting system is opened.
And current value in lighting system is adjusted according to the strong and weak of acquisition signal value at any time, so that the illumination for adjusting lighting system is bright
Degree.Circuit control chip, the extraneous light intensity signal value that circuit control chip detects photodiode are set on light-operated circuit plate
It is compared with the section codomain of setting, exports corresponding electric current.It further include miniature angular transducer on light-operated circuit plate, it is miniature
Angular transducer is used to measure the angle between gun guide rail and horizontal plane.When optical illumination gun sight (or gun barrel) and horizontal folder
When angle is greater than 70 degree, gun sight lighting system is automatically closed.This angle setting value is larger, prevents maloperation and causes optical illumination
System is closed.When optical illumination gun sight is when no mode of operation reaches 30 minutes or more, gun sight lighting system is automatically closed,
Battery is saved, unnecessary loss is reduced.
The bright gun sight of automatic illumination is installed on gun guide rail, and shooter keeps firing position, and gun angle with horizontal plane is small
In 70 degree.Photodiode in the bright gun sight of automatic illumination senses extraneous light intensity, sets when extraneous light intensity signal value is less than starting
When definite value, light emitting diode is in close state.Under complete darkness state, light emitting diode is not turned on.When extraneous light intensity is believed
Number value be greater than starting setting value when, open light emitting diode.Extraneous light intensity signal value and setting of the circuit control chip detection
Section codomain comparison after, export corresponding electric current.Each codomain corresponds to corresponding current value, and current value is bigger, light-emitting diodes
Guan Yueliang；Vice versa.Which provided 11 codomains, that is, are provided with 11 grades of brightness.Photodiode constantly acquires data, instead
It presents and is compared in circuit control chip, automatic regulating lightness.
Gun and horizontal sextant angle are greater than 70 degree, and when usually muzzle is towards ground or muzzle towards day, shooter is generally without shooting.
At this time to reduce energy consumption, light emitting diode is closed.It is bright that miniature angular transducer on light-operated circuit plate can sense automatic illumination
Gun sight and horizontal sextant angle, i.e. gun and horizontal sextant angle.Setting value is 70 degree in circuit control chip.When detection angle numerical value is small
When 70 degree, has one of the condition for opening light emitting diode.But detection angle numerical value is greater than 70 degree, closes light emitting diode.
Start lighting system, open light emitting diode, it is necessary to meet simultaneously: one, the extraneous light intensity value of photodiode sensing is big
In starting setting value；Two, the bright gun sight of automatic illumination and horizontal sextant angle are less than 70 degree.But close lighting system, it is only necessary to meet
One of condition: one, the extraneous light intensity value of photodiode sensing is less than starting setting value；Two, automatic illumination is bright takes aim at
Quasi- mirror and horizontal sextant angle are greater than 70 degree.
Meanwhile in order to save electricity, unnecessary electric quantity consumption is avoided, the bright gun sight of automatic illumination is in no mode of operation
Under, circuit control chip will turn off light emitting diode after 30 minutes.Solar panel is equipped on battery cover, battery uses
Chargeable button cell.When the bright gun sight of automatic illumination is exposed in extraneous sun luminous environment, solar panel absorbs too
Sunlight is converted into electric energy, charges automatically for battery, increases battery, accomplishes that the optical illumination gun sight life-cycle does not have to replacement
Battery.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
