US President Obama called out on the energy policy to develop the slogan of “cheap, clean, and efficient energy†in the United States. The development of Zero Energy Building is an important part of improving energy efficiency. According to 2006 statistics, lighting accounts for 11.6% of residential electricity consumption in the United States and 24.8% of commercial building electricity consumption. This data shows that reducing the energy consumption of lighting products is one of the necessary conditions for the development of zero-energy buildings, so it is promoted. The popularity of solid-state lighting is an important key for the United States to improve energy efficiency and reduce greenhouse gas emissions.
At present, LED lighting in the United States has reached a standard that can compete with traditional lighting. The biggest problem in promotion is that the price is too high, and OLED lighting is not yet in mass production. Based on the results of the workshop in San Diego in February 2005, the US Department of Energy set a multi-year development plan to increase solid-state lighting performance and lower its selling price by 2020. According to the plan, the average luminous efficiency target of cold white LED lamps in 2020 is 219 lm/W, the OEM price target is 1 US dollar per thousand lumens; the luminous efficiency target of OLED lamps is 127 lm/W, and the OEM price target is Thousands of lumens are $6 or $80 per square meter.
Since the ultimate goal of solid-state lighting development is to replace traditional lighting and become a product commonly used in daily life, in addition to the above technical development goals, the Solid State Lighting Development Planning Committee has also set a market-oriented solid-state lighting development milestone until 2020. In 2020, the target is a general-purpose LED lamp (luminaire) with a luminous efficiency of 140 lm/W or more and a price of less than $100.
In addition to setting solid-state lighting development goals, the US Department of Energy also provides subsidies from research and development to manufacturing, and supports the promotion of solid-state lighting products in the market. Although the current investment-to-management investment distribution is average, LED The proportion of subsidies for product manufacturing technology development has increased, indicating that the United States has begun to pay attention to the production of LEDs, and hopes to achieve the goal of reducing costs by improving production technology.
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.
