Abstract
The utility model discloses a shading plate with adjustable light transmittance. The shading plate with adjustable light transmittance comprises a fixed polarizing plate (1), a rotary polarizing plate (2) and a polarizing plate rotation slot (3), wherein the polarizing plate rotation slot (3) is fixedly mounted on the fixed polarizing plate (1), the rotary polarizing plate (2) is mounted between the fixed polarizing plate (1) and the polarizing plate rotation slot (3), and the rotary polarizing plate (2) can rotate freely between the polarizing plate rotation slot (3) and the fixed polarizing plate (1). By rotating the rotary polarizing plate (2), relative angular displacement of the fixed polarizing plate (1) and the rotary polarizing plate (2) can be generated, so a polarizing vector included angle of the fixed polarizing plate (1) and the rotary polarizing plate (2) can be adjusted, and thereby the light transmittance of the shading plate can continuously adjusted. The shading plate with adjustable light transmittance solves a problem that light transmittance of a shading device can not be continuously adjusted.
Description
Technical field
The utility model relates to a kind of shadow shield, particularly the adjustable shadow shield of a kind of transmittance.
Background technology
Shadow shield is mainly used in the blocking of light, and shadow shield is mainly fixed shadow shield both at home and abroad, and this shadow shield is general to adopt translucent or opaque material, and transmittance can not be adjusted.In the application of automotive light-shading board, opaque shadow shield can affect passenger's sight line, affects passenger's ride comfort, and its transmittance of translucent shadow shield is immutable, can not satisfy equally the passenger to the requirement of light.The shadow shield of birdman's form is opaque, can not satisfy equally the passenger for the double requirements of light and sight line.Some aquaculture also also has specific (special) requirements to light, and the light intensity in the physical environment is changeable, and translucent shadow shield and opaque shadow shield often can't meet the demands fully.
The utility model content
The shadow shield that provides a kind of transmittance adjustable is provided the purpose of this utility model, solves the problem that shade can not the continuous setup transmittance.
The shadow shield that a kind of transmittance is adjustable comprises: fixed Polarizer, rotary Polarizer, Polarizer swivelling chute.The Polarizer swivelling chute is fixedly connected with fixed Polarizer, and rotary Polarizer places between Polarizer swivelling chute and the fixed Polarizer and between Polarizer swivelling chute and fixed Polarizer and freely rotates.
Rotary Polarizer rotates freely between Polarizer swivelling chute and fixed Polarizer, rotate thereby fixed Polarizer is relative with rotary Polarizer, light is by passing through rotary Polarizer again behind the fixed Polarizer, when two Polarizer polarization vector directions are consistent, this moment, transmittance was the strongest, and this moment, transmittance was the most weak when two Polarizer polarization vector are mutually vertical.Two Polarizers rotate relatively, thereby make transmittance from by force to weak or regulate from weak to strong.
The present invention can regulate light intensity, and aquaculture and transportation are had wide practical use.
Description of drawings
The structural representation of the shadow shield that a kind of transmittance of Fig. 1 is adjustable.
1. fixed Polarizer 2. rotary Polarizer 3. Polarizer swivelling chutes.
Embodiment
The shadow shield that a kind of transmittance is adjustable, comprise: fixed Polarizer 1, rotary Polarizer 2, shadow shield swivelling chute 3, Polarizer swivelling chute 3 is fixedly connected with fixed Polarizer 1, and rotary Polarizer 2 places between fixed Polarizer 1 and the Polarizer swivelling chute 3 and at Polarizer swivelling chute 3 and 1 of fixed Polarizer and freely rotates.
Rotary Polarizer 2 rotates freely at Polarizer swivelling chute 3 and 1 of fixed Polarizer.Make fixed Polarizer 1 and rotary Polarizer 2 produce relative angular displacement by rotating rotary Polarizer 2, thereby regulate fixed Polarizer 1 and rotary Polarizer 2 polarization vector angles, make the transmittance of shadow shield adjustable continuously.When fixed Polarizer 1 was consistent with rotary Polarizer 2 polarization vector directions, this moment, transmittance was the strongest, and transmittance is the most weak when fixed Polarizer 1 and rotary Polarizer 2 polarization vector are mutual vertical.Two Polarizers rotate relatively, thereby make transmittance from by force to weak or regulate from weak to strong.
Claims (1)
1. shadow shield that transmittance is adjustable, it is characterized in that comprising: fixed Polarizer (1), rotary Polarizer (2), shadow shield swivelling chute (3), Polarizer swivelling chute (3) is fixedly connected with fixed Polarizer (1), and rotary Polarizer (2) places between fixed Polarizer (1) and the Polarizer swivelling chute (3) and between Polarizer swivelling chute (3) and fixed Polarizer (1) and freely rotates;
Rotary Polarizer (2) rotates freely between Polarizer swivelling chute (3) and fixed Polarizer (1); Make fixed Polarizer (1) and rotary Polarizer (2) produce relative angular displacement by rotating rotary Polarizer (2), thereby regulate fixed Polarizer (1) and rotary Polarizer (2) polarization vector angle, make the transmittance of shadow shield adjustable continuously; When fixed Polarizer (1) was consistent with rotary Polarizer (2) polarization vector direction, this moment, transmittance was the strongest, and transmittance is the most weak when fixed Polarizer (1) and rotary Polarizer (2) polarization vector are mutual vertical; Two Polarizers rotate relatively, thereby make transmittance from by force to weak or regulate from weak to strong.
