Zhongshan Torch District plans to complete the public lighting area to popularize LED lighting within two years

Zhongshan Torch Zone plans to complete the task of popularizing LED lighting in the public lighting field within two years, and plans to invest in new lighting in the roads, public places, government agencies, state-owned enterprises (including district hospitals, schools) and other financial or state-owned capital. Lighting products such as LED street lights, garden lights and landscape lights are used in the project. At present, the district has introduced relevant measures and has formulated a timetable for popularizing LED lighting products.

It is reported that the non-LED lighting products originally used in the public lighting area of ​​the district should be completed in batches before the end of 2013. By the end of 2013, the energy efficiency of the year-on-year lighting in this area will be more than 50%.

At present, some LED street lights have been rebuilt in the main sections near the torch exhibition center. The district encourages the use of contract energy management (EMC) operation mode, which is to determine energy conservation service companies, supervision agencies, energy audit and energy conservation assessment service agencies through bidding. In addition to the EMC model, LED lighting products can also be promoted and applied in various modes such as government investment and energy custody according to actual conditions. In the selection of energy-saving service companies to implement open tender selection, each owner unit to open an open bidding method, select an energy-saving service company, specifically undertake the implementation of LED lighting projects in the public lighting field. At the same time, strictly grasp the product access conditions, the products used in the promotion project must be the recommended catalogue products of the province's LED benchmarking system, and priority should be given to products with high energy efficiency and high local support.

Unmanaged POE Industrial Switches

PoE power supply switch refers to a switch that can provide network power supply for remote powered terminals through a network cable. It includes two functions: network switch and PoE power supply. It is a relatively common power supply device in PoE power supply systems.

PoE power supply switch refers to a switch that can provide network power supply to remote powered terminals through a network cable. It includes two functions: network switch and PoE power supply. It is a relatively common power supply device in PoE power supply systems. The port supports an output power of 15.4W, which conforms to According to the IEEE802.3af standard, the port supports an output power of 30W and conforms to the IEEE802.3at standard. It supplies power to standard POE terminal equipment through network cable power supply, eliminating the need for additional power wiring. A POE switch conforming to the IEEE802.3aT standard, the port output power can reach 15-60W. In layman's terms, a POE power supply switch is a switch that supports network cable power supply, which can not only realize the data transmission function of ordinary switches but also supply power to network terminals at the same time .
POE (Power Over Ethernet) means that without any changes to the existing Ethernet Cat.5 cabling infrastructure, it is used for some IP-based terminals (such as IP phones, wireless LAN access points AP, network Cameras, etc.) can provide DC power supply technology for such devices while transmitting data signals. The POE technology can ensure the normal operation of the existing network while ensuring the safety of the existing structured cabling, minimizing costs. 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
