Beijing, June 16, 2008 - Recently, at the national energy conservation publicity week in 2008, the national high-efficiency lighting product promotion project was launched. Osram, the world leader in lighting industry, won the bid for five projects in the bidding event and became one of the three companies with the most successful bidding projects. It will provide energy-efficient lighting products for the seven provinces and cities including Beijing and Shanghai.
China is a big country in the production and consumption of lighting products. The annual electricity consumption for lighting alone is 390 billion kWh, which is equivalent to the annual power generation of the four Three Gorges Projects. It is of great significance to vigorously develop green lighting projects. 2008 is a crucial year for China to achieve the 11th Five-Year Energy Saving and Emission Reduction Target. In order to mobilize all sectors of society to actively participate in the construction of resource-saving society and increase energy conservation propaganda, the 14th National Committee of the National Development and Reform Commission decided to jointly organize the 2008 National Energy Conservation Publicity Week from June 15 to 21, 2008.
As early as the beginning of 2008, the Ministry of Finance and the National Development and Reform Commission jointly deployed the national high-efficiency lighting product promotion project, and through the financial subsidy method, during the 11th Five-Year Plan period, 150 million energy-saving lighting equipments were provided and promoted to consumers and enterprises throughout the country. Saving 29 billion kilowatts. The event was publicly invited to bid for well-known lighting products suppliers at home and abroad. Osram has become the most successful foreign-invested company in one fell swoop, and will provide consumers and enterprises in seven provinces and cities such as Beijing, Shanghai, Hebei, Henan and Guangxi this year. Energy efficient lighting products. Before August 2008, OSRAM will provide Beijing with a total of 2 million energy-efficient lighting products. Before the end of 2008, OSRAM will provide a total of 5.8 million energy-efficient lighting products for the above-mentioned provinces and cities, including 2.2 million energy-saving lamps and fluorescent lamps. 3.6 million.
Mr. Zhuang Yuan, President of Osram China, said: Sustainability is an important strategy of Osram. Osram has spared no effort to contribute to global sustainable development, energy conservation and environmental protection, and bring advanced energy-efficient lighting technology to China. The participation in China's green lighting project is in line with the company's consistent sustainable development philosophy. OSRAM fully supports the task of promoting energy-saving lighting in Beijing, Shanghai, Henan, Hebei, Guangxi, Ningxia and Hunan, and strives to take practical actions. Actively cooperate with the efforts of the country to build an environment-friendly society.
Since entering the Chinese market in 1995, OSRAM Lighting has always focused on combining the value concept of energy conservation and environmental protection with its own social responsibilities. While continuously introducing advanced lighting and energy saving and environmental protection technologies to China, it has also organized many initiatives to promote environmental protection and energy conservation. Charitable activities. In July 2007, Osram (China) Lighting Co., Ltd. and China Conservation Panda Research Center signed a cooperation agreement to host a light-saving light, bright green home activities, and adopt three giant pandas for life (Europe, Europe, Division, Lang Lang also donated advanced lighting equipment that is conducive to the breeding of pandas. In the future, OSRAM will continue to focus on the development of energy conservation and environmental protection in China, and promote and promote its value concept of focusing on the harmonious development of society and the environment.

(1) Prevent electric shock accidents caused by electrical equipment and electrical circuit leakage;
(2) Preventing single-phase electric shock accidents during electricity use
(3) Timely cut off single-phase grounding faults in the operation of electrical equipment to prevent fire accidents caused by leakage
(4) With the improvement of people's living standards and the continuous increase of household appliances, personal electric shock and fire accidents caused by defects, improper use, and inadequate safety measures of electrical equipment in the process of using electricity have brought undue damage to people's lives and property. The emergence of leakage protectors provides reliable and effective technical means for preventing various accidents, timely cutting off power, and protecting equipment and personal safety.
The leakage protector should meet the following technical requirements
(1) The sensitivity of electric shock protection should be correct and reasonable, and the starting current should generally be within the range of 15-30 milliamperes
(2) The action time of electric shock protection should generally not exceed 0.1 seconds
(3) The protector should be equipped with necessary monitoring equipment to prevent it from losing its protective effect when the operating state changes. For example, for voltage type electric shock protectors, a neutral grounding device should be installed.
