Description

возникает эффект динамического рассеивани , заключающийс  в переходе жидкого кристалла от состо ни  прозрачности к состо нию , при котором он рассеивает световой ноток лампы.a dynamic scattering effect occurs, consisting in the transition of a liquid crystal from a state of transparency to a state in which it disperses the light of a lamp.

Электрическое ноле, приложенное к жидкокристаллическому элементу, регулируетс  вручную с помощью сопротивлени  8 или автоматически фоторезистором, сонротнвление которого мен етс  в зависимости от внешней освещенности транспортного средства .The electrical zero applied to the liquid crystal element is manually adjusted by means of a resistance 8 or automatically by a photoresistor, the sonotroot of which varies with the ambient light of the vehicle.

Иснользование изобретени , например,на транспортных средствах, позволит ПОВЫСИТЕ) активную безопасность их движени .The use of the invention, for example, on vehicles, will allow ENLARGE the active safety of their movement.

Claims (2)

1. Устройство дл  световой сигнализации, например, транспортного средства, содержащее светосигнальный фонарь,  ркость которого регулируетс  в зависимости от1. A device for light signaling, for example, a vehicle, comprising a signal lamp, the brightness of which is adjusted depending on внещнеи освещенности, и электрическук; цепь питани , отличающеес  тем, что, с целью перераспределени  светового потока в зону боковой видимости за счет равномерной освещенности поверхности рассеивани , оно снабжено жидкокристаллическим элементом, который расположен между лампой и рассеивателем светосигнального фонар  и подключен к электрическойexternal illumination, and electrical; A power circuit, characterized in that, in order to redistribute the luminous flux into the side visibility zone due to the uniform illumination of the diffusion surface, it is equipped with a liquid crystal element that is located between the lamp and the diffuser of the signal lamp and connected to an electric цепи питани  ламны, причем жидкокристаллический элемент защунтирован резистором .the power supply circuit of the lamp, and the liquid crystal element is bounded by a resistor. 2. Устройство по п. 1, отличающеес  тем, что, с целью автоматизации процесса2. The device according to claim 1, characterized in that, in order to automate the process изменени   ркости, в качестве регулируемого резистора применен фоторезистор.changes in brightness, a photoresistor is used as an adjustable resistor.
