Three main technical routes for deep comparison semiconductor lighting

In the preparation process of LED, the upstream substrate material is the main factor determining the performance indicators such as LED color, brightness, and lifespan. The surface roughness, thermal expansion coefficient, thermal conductivity coefficient, polarity influence, surface processing requirements, and lattice matching with epitaxial materials of substrate materials are closely related to the luminous efficiency and stability of high brightness LEDs. Therefore, substrate materials are the cornerstone of the technological development of the semiconductor lighting industry, and the technical route of substrate materials will inevitably affect the technical route of the entire industry, which is the key to the entire industry chain. At present, there are three main technological routes for semiconductor lighting, namely the sapphire substrate LED technology route represented by Nichia Chemical in Japan, the silicon carbide substrate LED technology route represented by CREE in the United States, and the silicon substrate LED technology route represented by China Crystal Energy Optoelectronics. On January 8, 2016, the "Silicon Substrate High Efficiency GaN Based Blue Light Emitting Diode" technology project jointly led by Jiang Fengyi from Nanchang University and Jingneng Optoelectronics won the only first prize in the 2015 National Science and Technology Award for Technology Invention, once again igniting the dream of Chinese chips in the LED industry. The award of the silicon substrate technology project indicates that the silicon substrate has been proven feasible by the country and has been elevated to the national strategic level. Silicon substrates may usher in large-scale commercial applications.ving the common pet hair problem faced by pet families. Efficient drying technology can ensure that clothes do not need to be dried while avoiding wrinkles or hardening. The large capacity design makes this dryer an ideal cleaning companion for families, whether it's heavy winter bedding or daily clothing and miscellaneous items, it can accommodate and provide satisfactory drying results. The built-in high-precision sensor can monitor the temperature and humidity of clothes in real time, automatically adjust the working status, and prevent clothes from being damaged due to excessive drying or affecting the user experience due to insufficient drying.

In summary, pet dryers are not only user-friendly, but also provide a fast and safe drying experience for pets after bathing, while ensuring their comfort and safety.
