As a demonstration city of ten cities and counties, Hunan Xiangtan has actively promoted green lighting projects in recent years, and has taken measures to promote urban lighting energy conservation. In recent years, the Lighting Management Office of the Municipal Urban Management Law Enforcement Bureau has carried out energy-saving renovations on street lights of many major sections of the city, replacing the traditional high-pressure sodium lamps with new energy-saving LED lamps. The LED street lamp has low energy consumption, the power saving rate is nearly 52 higher than that of the high-pressure sodium lamp, the service life is longer, and the loss of its own electric energy is reduced. The person in charge of the city lighting management office introduced. In 2012, Xiangtan invested nearly 6 million yuan to renovate 24 street lights and install 386 LED street lights. From 2013 to 2014, Xiangtan launched a green lighting demonstration road construction project with an investment of nearly 9 million yuan to implement LED street lighting renovation for Ji'an Road, Shuyuan East Road, Shuyuan West Road, Second Bridge and North Second Ring Road. According to statistics, there are 22,000 è·¯ street lamps in Xiangtan City. At present, nearly 2,200 street lamps use LED light sources. According to the renovation plan, in 2015, Xiangtan will also carry out LED street lighting renovation for the 906ç› high-pressure sodium lamp on Bantang Avenue and Furong Avenue. This year, the Lighting Management Office also upgraded the urban lighting monitoring system, using a combination of light control and time control to determine whether the street lights are turned on or off according to the illuminance in the preset time zone. The need for lighting avoids the unnecessary opening of street lights, which saves a lot of power.

Metallic materials Charpy notch impact test is the special equipment which checks the Charpy V-type and U - type gaps. The instrument magnifies impact specimen gaps outline and projects it onto screen to compare with standard sample drawing of the impact specimen V-type or U-type gaps. This helps to examine whether the tested impact specimen gap is qualified or not. It can meet the ASTM E23,EN 10045,ISO 148,ISO 83 and other international standards.
