Cree, the leader in the LED lighting market, once again announces the industry's highest level of LED light efficiency recording, with white light high power LED light efficiency achieving 208 lm/W. This research and development result is an important milestone in the solid-state lighting industry and is the embodiment of Cree's unremitting pursuit of LED lighting performance.
Cree's test results show that a light effect of 208 lm/W is achieved when the correlated color temperature is 4579K. The LED efficacy test was conducted under standard conditions at room temperature with a drive current of 350 mA.
"We have now exceeded the barrier of 200Lm/W, a single-chip high-power white LED." John Edmond said. “This is the result of improved blue light output power, lowering the operating voltage to achieve higher conversion efficiency. We will continue to promote white LED technology to enable white lighting products in the market to continue to achieve higher light efficiency.â€
Although this level of performance LEDs are currently not in volume production at Cree, Cree's high-performance LED series continues to maintain its position as an industry leader. (Compile: Looking up at the stars)
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.
