Problems solved by technology

Usually the required light barriers are made of materials such as liquid crystal light valves containing glass liquid crystal cells and ferroelectric ceramic light valves, but because these materials are all straight, hard and brittle materials, they cannot be compatible with the car body, especially Combined with the curved front safety glass, the light barrier required for anti-glare can only be placed in front of the driver as an independent object, which not only increases the difficulty of installation and possible safety hazards, but also because of the additional Adding something that violates the driver's driving habits and reduces the practicality of the anti-glare lighting system

Embodiment Construction

[0009] In accompanying drawing 1, 1 is the light-shielding plate of side view, transparent conductive film electrode 4 and transparent conductive film electrode 6 are coated on transparent holding plastic sheet 3 and transparent holding plastic sheet 7 respectively by spraying, sputtering or other means superior. The transparent clamping plastic sheet 3 and the transparent clamping plastic sheet 7 clamp the polymer liquid crystal film 5 with one side coated with a transparent electrode, and this clamping can be realized by bonding, or only relying on airtightness and utilizing atmospheric pressure. The other side of the transparent clamping plastic sheet 3 is attached to the windshield 2 of the vehicle. The transparent clamping plastic sheet 3 and the transparent clamping plastic sheet 7 lead out the transparent conductive film electrode 4 and the transparent conductive film electrode 6 with flexible electrodes at the same time, and are connected to the light barrier drive out...

Abstract

The invention relates to a light-blocking board used for an impulse anti-bewildering illuminating system. The invention adopts a bendable polymer liquid crystal light valve, which ensures the light-blocking board to cling to a curved face so as to be integrated with a front baffle glass or a motorcycle helm veil into a whole. And the polymer liquid crystal light valve works in a switching way and absorbs the diffused light to be black color in a closed state.

Description

technical field [0001] The invention belongs to the pulse type anti-glare lighting technology. Background technique [0002] In the Chinese patent application 9314064.1, it is proposed to combine the pulse lamp lighting with a light shield with synchronous opening and closing and light transmission with a small duty cycle to achieve the purpose of anti-glare. Usually the required light barriers are made of materials such as liquid crystal light valves containing glass liquid crystal cells and ferroelectric ceramic light valves, but because these materials are all straight, hard and brittle materials, they cannot be compatible with the car body, especially Combined with the curved front safety glass, the light barrier required for anti-glare can only be placed in front of the driver as an independent object, which not only increases the difficulty of installation and possible safety hazards, but also because of the additional Adding one thing violates the driver's driving ha...
