On November 12, 2010, Jingyuan Optoelectronics announced a breakthrough result: high voltage (HV) LED die can achieve 162 lumens / watt in cool white light, making LED applications in lighting further.
The high-voltage DC integrated array LED die developed by Jingyuan Optoelectronics using the most advanced technology can meet the needs of environmental awareness such as energy saving and efficiency improvement, and is bound to become the mainstream of general lighting applications. Compared with traditional LEDs, due to the advanced and stable high-voltage chip design, high-voltage LED dies can show low energy consumption and high efficiency. The efficiency of the overall light output is enhanced by flexible voltage and current adjustments and simplified LED package and drive line design.
Epistar Lab is committed to the development of low-energy and high-efficiency LED technologies and products. This 45-mil high-voltage LED die achieves a high performance level of 162 lm/W in cool white light at operating conditions of 20 mA and 5000 K.
Digital currency transactions allow users to convert existing digital currencies into other digital currencies. The entire transaction does not involve any legal tender. Because of the relatively loose regulation, the mainstream digital currency trading platform also opened this function.Digital Asset Exchange (DAE) is a platform for matching transactions between digital currencies, digital currencies and legal currencies. It is the main place for encrypting the circulation and price determination of digital currency transactions.
Compared with traditional stock exchanges, digital asset trading platform not only matches transactions, but also plays the role of market maker and investment bank. The role of the market maker in the trading platform can increase the liquidity of the market, and the trading platform can earn the transaction price difference. The role of the investment bank of the trading platform is to provide services such as issuance and underwriting of digital currency, from which the trading platform collects money fees, or collects deposits in the form of community voting of the trading platform.
