中文百科

光敏电阻 Photoresistor

（重定向自Light Dependent Resistor）
光敏电阻
Fotocelda o fotorresistencia, cambia su valor resistivo (Ohms) conforme a la intensidad de luz. Mayor luz, menor resistencia y viceversa..
Three photoresistors with scale in mm

光敏电阻是利用光电导效应的一种特殊的电阻，简称光电阻，又名光导管。它的电阻和光线的强弱有直接关系。光强度增加，则电阻减小；光强度减小，则电阻增大。

Photoresistor 光敏电阻

（重定向自Light Dependent Resistor）
Three photoresistors with scale in mm
The internal components of a photoelectric control for a typical American streetlight. The photoresistor is facing rightwards, and controls whether current flows through the heater which opens the main power contacts. At night, the heater cools, closing the power contacts, energizing the street light.
光敏电阻

A photoresistor (or light-dependent resistor, LDR, or photocell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light- and dark-activated switching circuits.
