The core component of a photosensitive receiver tube is a photoresistor, and its principle is that when light shines on the photoresistor, the resistance of the photoresistor will significantly decrease. Within a limited range, the degree of reduction in resistance is proportional to the intensity of the light, that is, the stronger the light, the smaller the resistance.
Light sensitive receiving tubes and other devices utilize the characteristic of photoresistors to convert optical signals into electrical signals for mechatronics control, making them widely used.
Photoresistors are classified according to their sensitivity to different spectra of light, including ultraviolet photoresists, infrared photoresists, and visible photoresists (mainly sensitive to yellow light).
For example, the application in fully automatic combustion engines is collectively referred to as light sensing: UV light sensing can sense the ultraviolet rays in the spark of the igniter and the flame, and can be used in various combustion engines, but due to its high cost, it is mainly used for monitoring the flame and ignition spark in gas combustion engines and dual-purpose combustion engines; Ordinary light sensing is sensitive to yellow light and can only be used to monitor the yellow flames generated by the combustion of diesel, heavy oil, kerosene, etc. It is insensitive to ultraviolet light and relatively inexpensive, so most fuel combustion engines use ordinary light sensing to monitor flames.
Shenzhen Tengjie Optoelectronic Technology Co., Ltd. was established in 2009 and is located at the Gongming exit of Longda Expressway in Guangming New District, Shenzhen, in the northwest of China‘s Special Economic Zone. It is a technology-based enterprise specializing in the research and development, manufacturing, and sales of LED car light sources.
