Blinking light-emitting diode (BTS) is a special light-emitting device composed of CMOS integrated circuits and light-emitting diodes, which can be Macor Ceramics used for alarm indication and under-voltage and over-voltage indication.
When the flashing light-emitting diode is in use, there is no need to connect other components, as long as the appropriate DC working voltage (5V) is applied to both ends of its pins, it can flash and emit light. Infrared light-emitting diodes, also known as infrared-emitting diodes, are light-emitting devices that can directly convert electrical energy into infrared light (invisible light) and radiate it out. They are mainly used in various light control and remote control Macor Ceramics emission circuits. The structure and principle of infrared light-emitting diodes are similar to ordinary light-emitting diodes, but the semiconductor materials used are different. Infrared light-emitting diodes usually use gallium arsenide (GaAs), gallium aluminum arsenide (GaAlAs) and other materials, and are packaged with fully transparent or light blue and black resins. Commonly used infrared light-emitting diodes are SIR series, SIM series, PLT series, GL series, HIR series and HG series. Ultraviolet light-emitting diodes (UV LEDs) based on semiconductor materials have the advantages of energy saving, environmental protection and long life, and have great application value in the fields of sterilization, medical treatment and biochemical detection. In recent years, semiconductor ultraviolet optoelectronic materials and devices have attracted more and more attention around the world and become a research and development hotspot. From December 9th to 12th, 2018, the 3rd "International Symposium on Ultraviolet Materials and Devices" (IWUMD-2018) hosted by the Institute of Semiconductors, Chinese Academy of Sciences was held in Kunming, Yunnan Province. More than 270 representatives from 12 countries attended the meeting. This conference brought together the latest research and development reports of many top experts in the fields of UV light-emitting diode materials and devices at home and abroad. Ultraviolet light-emitting diodes are the main trend in the development of nitride technology and third-generation semiconductor material technology, and have broad application prospects. In order to speed up the development of the third-generation semiconductor solid-state UV light source, the Ministry of Science and Technology of China has implemented a key R&D program (2016YFB0400800) of "Key Technologies of the Third-Generation Semiconductor Solid-State UV Light Source Materials and Devices". The support of the national key research and development plan and the holding of the International Symposium on Ultraviolet Materials and Devices will accelerate the market-oriented application of my country's third-generation Macor Ceramics semiconductor ultraviolet light sources, and promote the development of my country's ultraviolet semiconductor light-emitting diode materials and device technology. positive effect. In 1987, Deng Qingyun of Kodak Company successfully prepared low-voltage, high-brightness organic light-emitting diodes (OLEDs), showing the world for the first time the commercial application prospects of OLEDs'". In 1995, Kido published in the journal Science The article on white organic light-emitting diodes (wOLEDs), although not very efficient, opened the prelude to the research of OLED lighting. After decades of development, the efficiency and stability of OLEDs have long met the requirements of small-sized displays, and are subject to many high-end Favored by instrumentation, mobile phone and mobile terminal companies, large-scale technology is also becoming more and more perfect.
