According to the Reuters September 19, South Korea Seoul Semiconductor LED professional company and its subsidiaries, said the violation of subsidiaries Acrich technology, LED lighting product sales of US companies, the federal court of California has filed a patent infringement lawsuit. Seoul Semiconductor said in a complaint that several LED lights, including filament LED lamps, sold by Archipelago Lighting, Inc., infringe on 12 related patents of Seoul Semiconductor. The infringed Seoul Semiconductor Acrich patents include high-voltage drive LED drive technology, multi-chip manufacturing and multi-junction technology (MJT), LED packaging, filament LED manufacturing technology, LED epitaxial growth and chip manufacturing technology, all of which manufacture and drive LEDs. The necessary core technology. Conventional LEDs typically drive one LED (device) at a high current at a low voltage of 3V. Therefore, in order to raise the brightness of the illumination, it is necessary to arrange a plurality of elements and connect the respective elements to each other (wiring). Therefore, the size of the drive circuit is increased, the price is increased, and the possibility of malfunction due to wiring is also high. Compared with LED Acrich However, with the optimization of LED driver technology, Acrich can integrate multiple LED chips into a small-area high-voltage operation and multi-chip mounting technology (MJT), which can simultaneously obtain high voltage and output with a small number of LEDs. Since it is directly driven directly from the AC without a converter, the overall efficiency of the product (Wall-plug Efficiency) is high, because power conversion process is not required, so the power loss in the circuit can be minimized. Moreover, as the number of LEDs used is reduced, space utilization is increased, which simplifies circuit design and reduces the size and cost of illumination. Acrich technology for street lighting, automotive applications Acrich technology is not only suitable for lighting, but also extends to IT and automotive. In the field of lighting, high-voltage lighting products exceeding 12V and 18V are very popular in the market, and the demand for ultra-high voltage driving light sources such as 36V and 48V is also increasing. In order to manufacture such a high-voltage driving light source, it is necessary to combine high-voltage driving LED driving technology and multi-chip mounting technology. Acrich's light source is recognized for its superior technology and its products have been used in streetlights and commercial lighting around the world including Korea, USA, China, Europe, Southeast Asia, Mongolia and Kazakhstan. Acrich streetlight installed in Ulaanbaatar, Mongolia Acrich technology for lighting, IT and automotive applications Acrich technology is widely used in large area displays In the IT field, Acrich technology is used in large-area displays for electronic devices such as TVs. Acrich technology simplifies the internal system of the display by innovation, greatly improving life and efficiency, reducing the space occupied by the circuit, and greatly reducing the size and thickness of the finished product. In recent years, Acrich technology has also been used in the rapidly growing ultra-thin UHD display products. With Acrich technology, full-array local dimming can be achieved to improve contrast performance, so the high-resolution Back Light Unit is receiving high attention from the industry as a next-generation solution. In addition, Acrich, as a typical high-power LED, is expanding its applications to areas that require high light output, such as landscape lighting, headlights, daytime driving lights, and cell phone flash. Acrich technology was developed from the mid-1990s and was successfully mass produced in 2005. Every year, Seoul Semiconductor is committed to technological innovation and high-level and continuous introduction of new products. At present, it has more than 1,000 LED-related patents such as Acrich technology. Recently, the demand for the high-voltage LED market has soared, ignoring the patent portfolio of Seoul Semiconductor, and companies stealing technology have emerged one after another, through active patent rights. Create a beautiful society that respects intellectual property. The director of the Seoul Semiconductor Research Institute said, "At present, extensive investigations have been conducted on LED TVs, general lighting and automotive lighting products using the Acrich technology.", "Acrich technology developed to protect Seoul Semiconductor for decades." For companies that ignore patent infringement warnings and continue to use infringements, they will actively respond and file patent litigation. This will enable young people and SMEs to see hope." Behind patent litigation It is understood that Seoul Semiconductor is a professional semiconductor manufacturer in Korea. It ranks among the top five in the global LED industry. At present, it has more than 10,000 related patents in the semiconductor field. Its self-developed unpackaged LEDs and multi-structure chips. DC communication can drive four innovative technologies such as Acrich and UV sterilization, leading the development of the global LED field. Since winning the patent lawsuit against Taiwan in China in 2003, Seoul Semiconductor has initiated more than 50 patent wars in the United States, Europe, Japan, South Korea and other places, and all ended in victory.
