Nanchang University LED lighting project has been supported by the national "863 Plan"

Recently, the Ministry of Science and Technology announced the “12th Five-Year Plan” national high-tech research and development plan (863 program) new materials technology field "macro-lighting materials, key materials, technology research and development" major project list, a total of 14 projects across the country have been approved, including Nanchang University The "Substrate GaN-based LED with large-size Si substrate epitaxial growth, chip preparation and packaging technology" project has been funded more than 50 million yuan, accounting for 21.6% of the total amount of this major project, ranking first in 14 topics.

The topic was chaired by Wang Li, a 35-year-old deputy director of the National Silicon-based LED Engineering Technology Research Center. The main task of this project is to develop a silicon substrate with higher cost performance and LED lighting materials and chips, launch the second generation of silicon substrate LED chips, promote the development of industrial chain and innovation chain to high-end, and gradually form a strategic emerging industry with international competition. .

TO-220 package

TO-220 Transistor Outline Package is a type of in-line package often used in high-power transistors and small and medium-sized integrated circuits.

It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connects to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit.Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport.

TO-220 package is a kind of in-line package that is often used for fast recovery diodes. TO-220AC represents a single tube with only two pins and only one chip inside.

The diodes are packaged in TO-220AC and can be used in switch mode power supplies (SMPS), power factor correction (PFC), engine drives, photovoltaic inverters, uninterruptible power supplies, wind engines, train traction systems, electric vehicles and other fields.
