TUV Nande Group analyzes LED lighting drive technology

Recently, TUV SÃœD (hereinafter referred to as TUVSUD) was invited to participate in the 5th LED General Lighting Drive Technology Seminar hosted by Power Network. TUVSUD's technical experts for LED driver products, combined with the new European standard EN61347-1:2008 A1:2011 A2:2013 and EN61347-2-13:2006, in terms of testing and structure, for the majority of power network members and LED drivers The manufacturer explained the analysis. The LED driver is a power converter that converts the power supply to a specific voltage and current to drive the LEDs. It seems to be inconspicuous in the design of the entire lighting product, but it is extremely critical. Due to the obvious advantages of LED lighting in environmental protection and energy saving, countries are actively promoting LED lighting plans. In 2013, the global LED lighting output value increased significantly, and also increased the demand for LED drive power, making LED drive power into a rapid development stage. Market analysts generally expect that the market size of China's LED driver power supply will expand by billions this year and next, and there will be a certain degree of breakthrough in technology, especially in the field of high-power LED driver power supplies, because of the strong LED street lights. Demand-driven, it is likely to show a good growth trend. At present, the LED industry is in the growth stage. With the continuous development of LED lighting technology and the continuous entry of enterprises, the LED industry will also develop rapidly. In the next 3-5 years, LED lighting will be a fast-growing stage. LED lighting power supply will also explode at this stage. The relevant departments only counted that the number of LED driving power sources in China reached 7 million units in 2013. The market scale has been Expanded to 1.75 billion. Facing the development trend of LED lighting products at home and abroad, Mr. Zhao Ligang, technical manager of TUVSUD Lighting Product Service Department, was invited to give a speech. LED lamps have more chances of failure than traditional lamps, which also affects the development of LED industry. The important factor is the power supply, so the main contradiction needs to solve the power problem. The quality of the power supply depends on the materials, process, environment and maintenance of the power supply. The driving power supply is an important part of the development of the LED industry chain. The quality of the LED driving power supply directly restricts the reliability of the LED lighting products. Therefore, in the LED industry's increasingly prominent position, how can LED driver power suppliers grow and improve their products? Quality and brand advantage are even more important. TUVSUD adheres to the authority certification and creates a value service concept. With professional technology and huge global expert resources, it closely monitors the international market dynamics, the regulatory trends of market access and the challenges and opportunities facing domestic LED driver products. Directional information and one-stop service solutions actively assist Chinese manufacturers and exporters in solving technical problems and helping international markets to clear customs. Founded in Germany about 150 years ago, TUV SÃœD is one of the world's leading technology service companies, covering a wide range of areas including testing, certification, inspection, information and expert guidance. With more than 800 representative offices around the world and approximately 20,000 employees, the company is committed to providing customers with optimized services in technology, systems and operations. TUV SÃœD has been operating in China for more than 20 years. To date, more than 20,000 customers have been provided with corresponding services.

Stamping

Stamping is a manufacturing process that involves applying pressure to a material to deform it into a desired shape or size. There are various types of stamping processes utilized in the industry, each with its unique set of advantages and disadvantages. In this article, we will describe some of the most common types of stamping processes.
Blanking: Blankings are flat pieces of sheet metal that have been precisely cut and punched out from larger sheets of metal. Blanking is a process used to produce these flat pieces, and is ideal for producing large quantities of uniform, flat parts.
Coining: Coining is a stamping process used to create impressively flat and precise features - often used in creating coins or bearing seals.
Drawing: Drawing involves pulling a flat piece of metal through a die with a punch tool to form it into a three-dimensional shape. This process is commonly used in the creation of products such as automobile fenders, cans, and ship hulls.
Embossing: Embossing is the process of applying raised designs or patterns to a flat piece of metal by impressing the metal with a die. This process is popularly used in the production of decorations and signage.
Piercing: Piercing is the process of punching or drilling holes in a metal sheet. It is widely used in creating products such as luggage tags, name plates, and metal attachments.
Blanking and forming: Blanking and forming involve using a single die to create a part that has a variety of features, both flat and formed. It is a highly efficient process for creating complex parts.

Overall, stamping is a versatile manufacturing process that plays a crucial role in the production of a wide range of metal parts and components. By understanding the different types of stamping processes, manufacturers can select the most suitable process for producing high-quality parts in an efficient and cost-effective manner.
