Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and 2, an automatic switching nuclear flashing goggles comprises a goggle bracket, wherein a goggle assembly 1, a photodiode 2, a controller 3 and a battery box 4 are mounted on the goggle bracket, the battery box 4 is electrically connected with the controller 3, the goggle assembly 1 comprises a first polarizing film 11, a transparent ceramic electrode plate 12 and a second polarizing film 13 which are sequentially arranged, the first polarizing film 11 and the second polarizing film 13 are mutually orthogonally arranged, after the transparent ceramic electrode plate 12 is loaded with voltage through the battery box 4 and the controller 3, the light passing through the first polarizer 11 is changed into elliptically polarized light and then passes through the second polarizer 13, thereby, the eye protection lens component 1 is in a light transmission state, the transparent ceramic electrode plate 12 is electrically connected with the controller 3, the controller 3 is also electrically connected with the photodiode 2, and the photodiode 2 is used for connecting or disconnecting the controller and the transparent ceramic electrode plate 12. The ceramic electrode plate 12 has an electrically controlled variable birefringence effect, and when a high voltage is applied to the ceramic electrode plate 12, the PLZT ceramic electrode plate becomes a negative uniaxial crystal (PLZT lead lanthanum zirconate titanate ceramic) by means of an electrically induced phase change.
In addition, the transparent ceramic electrode plate 12 receives an input voltage and then becomes lead lanthanum zirconate titanate ceramic, and the light passing through the first polarizer 11 passes through the lead lanthanum zirconate titanate ceramic and then becomes elliptically polarized light, and then passes through the second polarizer 13, so that the eye protection lens assembly 1 is in a light transmitting state.
In addition, the photodiode 2 is turned on, and the voltage applied to the transparent ceramic electrode sheet 12 by the controller 3 is cut off; the photodiode 2 is turned off and the recovery controller 3 applies a voltage to the transparent ceramic electrode pad 12.
The photodiode 2 is turned on when irradiated by an external light source, and turned off when the irradiation by the external light source is lost.
The battery pack 4 is a 6V dc power supply having a switch.
The nuclear flashing goggles with the automatic switch have the following specific working principles: the power switch is turned on, the power box 4 loads input voltage on the ceramic electrode plate 12 through the controller 3, through electric induction phase change, the PLZT ceramic electrode plate becomes negative uniaxial crystal (PLZT lead lanthanum zirconate titanate ceramic), when external light passes through the first polaroid 11, elliptical polarized light is formed after the external light passes through the transparent ceramic electrode plate 12, the last part of light passes through the second polaroid 13, and the goggle lens component 1 is in a transparent state at the moment. When strong light (laser, nuclear flash and the like) irradiates, the photodiode 2 generates photocurrent, the controllable silicon conducts energy, the input voltage of the controller 3 is zero, the voltage loaded on the transparent ceramic electrode plate 12 is small, the polarized light passing through the first polarizing film 11 cannot change the direction when passing through the transparent ceramic electrode plate 12, the mutually orthogonal second polarizing films 13 block the light rays to pass through, and the eye protection lens component 1 is in an opaque state, so that the aim of protecting eyes is fulfilled. After the strong light is passed, the photoelectric signal is weakened, the silicon controlled rectifier is turned off, the voltage applied to the ceramic electrode plate 12 is reestablished, the eye protection lens component 1 is restored to the transparent state, and the opening or closing of the goggles is realized through the photodiode and the controller.
Different from the prior art, the nuclear flashing goggles with the automatic switch automatically realize the switching of the light transmission state and the light non-transmission state of the goggle lens component through the photodiode.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
