According to the person in charge of the Economic and Information Committee of Yantai City, at present, 498 sets of 4.5-meter high garden lights at Binhai Road in Yantai City are all applied with LED lighting, and development zones, high-tech zones and Jingouzhai overpasses are also used. LED lighting has obvious advantages compared with other lamps, but there are also problems such as high price and poor light decay performance.
The Yantai Economic and Information Technology Commission will organize the implementation of LED indoor lights (reflective lights, downlights), LED street lights, urban road tunnel lights, and LED road tunnel lights demonstration projects with housing construction and transportation departments. financial support.
In response to the "Proposal on Further Increasing Science and Technology Investment" proposed by the CPPCC National Committee, the person in charge of the Science and Technology Bureau of Yantai City said that since 2006, the municipal party committee and the municipal government have increased the investment in financial science and technology funds year by year, and the municipal application technology research and development funds. Gradually increasing, from 32.87 million in 2006 to 49.6 million in 2012, the average annual growth rate is 10%. The funding increased from 4 billion yuan in 2007 to 11.2 billion yuan in 2011.
This year, Yantai City also initially established a new mechanism for science and technology venture investment. First, it conducted a pilot project in the high-tech zone. The municipal finance took 20 million yuan to establish a “risk investment guidance fund†with the high-tech zone to guide financial and venture capital institutions. SME services. Taking "risk compensation" as the main form to solve the financing difficulties of small and medium-sized enterprises. According to the statistics of the financial department, the total size of the venture capital fund has reached 240 million yuan, and the total scale of 2015 is 300 million yuan.
Bi Directions Thyristor (Triac)
Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
