Additional issues, LED, and two hot keywords are brought to the market in Wuhu City. Recently, Dehao Runda announced that the CSRC approved the approval of its 1.6 billion yuan LED project. Sanan Optoelectronics, which is launching an additional issuance plan in conjunction with Dehao Runda, is still waiting. Intriguingly, the funds raised by Dehao Runda's private placement will be used for the LED project in Wuhu, and the Sanan Optoelectronics issuance plan will also be used for the company's LED project in Wuhu. Wuhu became the center of the layout of the two LED projects.
Dehao Runda Hometown Layout
On December 16, 2009, Dehao Runda officially started the LED project in Wuhu, and the green lighting plan with a total investment of about 3 billion yuan began in the salute. Wang Donglei, a literary entrepreneur who is known as the breadmaker of the industry, hopes to complete the major layout of the LED industry in Anhui's hometown. In his eyes, this project will become one of the largest LED industry bases in China after five years. The annual output value is estimated to exceed 10 billion yuan.
Dehao Runda's special project is small household appliances, which ranks among the best in the domestic small household appliance industry. After optimistic about the LED industry, Dehao Runda decided to build a base in the middle and lower reaches of the entire industrial chain covering the LED lighting industry in Wuhu. Including chip manufacturing and cutting in the core technology areas of the industry will also be carried out in Wuhu. The base covers an area of ​​440,000 square meters and has a planned total investment of 3 billion yuan. It is understood that three-quarters of the issued objects of Dehao Runda's additional issuance project belong to Wuhu City State-owned Assets Supervision and Administration Commission. After the completion of the additional issuance, Wuhu City's company holds 21.52%.
Sanan Optoelectronics signed the project
Just as Dehao Runda announced that it had entered Wuhu and entered the LED project for only two months. On February 26, 2010, another LED company, Sanan Optoelectronics, also selected Wuhu as its base for the LED industry.
It is reported that Sanan Optoelectronics Co., Ltd. is the earliest and largest full-color ultra-high brightness LED epitaxial wafer and chip industrialized production enterprise in China. It is a national high-tech industrialization demonstration project, a leading enterprise in semiconductor lighting engineering, and aerospace department. Strategic partners, the current production scale accounts for more than 58% of the total domestic production capacity, ranking first in the country.
The total investment of Sanan Optoelectronics Wuhu Optoelectronics Industrialization Base is about 12 billion yuan, and the first phase investment is 6 billion yuan. The first phase of the project will be put into operation during the year. After the project is completed, Wuhu will become the largest LED epitaxial wafer, chip, package and downstream application product manufacturing, R&D and experimental base in China and the world. To this end, Sanan Optoelectronics will purchase 200 sets of MOVCD equipment with world-class levels in Wuhu, and build a national first-class LED R&D and experimental base. And Sanan Optoelectronics and Wuhu have only two months from contact to signing.
Want to build the largest "Optical Valley" in China
Although the investment scale of the two companies is not small, they all position the Wuhu project as a whole industrial chain base covering LED chip production, cutting and packaging, and at the same time emphasize Wuhu as the largest and first-class LED industry base in China.
At the same time, after confirming the issuance of the purchase of Dehao Runda, Wuhu did not have to be inferior. After the announcement of the issuance plan, Sanan Optoelectronics successively received subsidies from the Wuhu Municipal People's Government for the purchase of LED main generating equipment MOVCD. paragraph.
It is not difficult to see that Wuhu City's determination to build an LED industry base is another emerging pillar industry that Wuhu has made after the pillar industries such as automobiles and building materials.
Optical Line Terminal (OLT)
POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) The technology that can provide DC power for such devices while transmitting data signals is a switch that supports Power over Ethernet.
POE is also known as a power supply system based on local area network (POL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short. This is the use of existing standard Ethernet transmission cables to transmit data and data at the same time. The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Ethernet power supply system. It adds related standards for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard.
IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the shortcomings of this standard have been restricting the expansion of the market. Until June 2003, the IEEE approved the 802.3af standard, which clearly stipulates the power detection and control items in the remote system, and connects routers, switches, and hubs to IP phones, security systems, and wireless LANs through Ethernet cables. The method of power supply for points and other equipment is regulated. The development of IEEE 802.3af includes the efforts of many company experts, which also allows the standard to be tested in all aspects.
The IEEE 802.3at standard was formulated in 2005 and promulgated in 2009. The 802.3at standard output power can reach 30W, and the available power at the receiving end is 25.5W.
The IEEE 802.3 working group and various manufacturer alliances launched POH-POWER OVER HDBASET in the industry at the end of 2012.
Using the current 4-Pair four-pair wire technology plus, the bilateral power supply can reach 60-100W power, which can be achieved by using 5 or 6 types of wires. It is used in high-definition video promotion to supply power to 42" LED TVs. According to the new regulations in 2010, the power consumption of 42" LED TVs needs to be less than 70W.
