Seoul Semiconductor, a world-renowned LED manufacturer, said on April 13 that it has filed a lawsuit against the German electronic component distributor Mouser Electronics for infringing its high-power LED-related patents in the Düsseldorf District Court.
According to Seoul Semiconductor related sources, the patent infringement products are high-power LEDs produced by Everlight Electronics and most LED manufacturers, the world's top ten LED manufacturers. Mouser has become the object of this lawsuit because of the sales and circulation of LED products manufactured by these companies. In the lawsuit, Seoul Semiconductor required the infringement prohibition order, recall and destruction of infringing products and damages for these infringing products.
High-power LED technology is widely used in outdoor lighting such as mobile phone flash, car headlights, street lamps and UV LED products. The patented technology effectively releases the light generated inside the LED chip to the outside of the LED chip by processing the surface of the LED chip, thereby greatly improving the light intensity and brightness, and is required to be used in the manufacture of high-efficiency LED.

The global LED market scale reached 15,612$M in 2016, of which high-power LEDs accounted for 43% of the total LED market, about 6,722$M. By 2020, the global LED market is expected to reach 19,240$M, and accordingly, the high-power LED market will also grow substantially. The high-power LED patent technology involved in this lawsuit is widely used in the LED market of 6,722$M scale, and the patent litigation related to high-power LED is expected to increase further.
Seoul Semiconductor will begin this lawsuit and severely respond to violations of its high-power LED technology. In addition, companies that infringe on Seoul Semiconductor's LED packaging and chip-related patents have been confirmed, and Seoul Semiconductor is discussing additional patent litigation against related companies.
Seoul Semiconductor invests more than 10% of its sales each year in research and development, and has 12,000 patents. Its patent strength is recognized worldwide. Since its inception, Seoul Semiconductor has never lost in all patent litigation, creating the myth of winning. In the past 2013, the Semiconductor Electric Manufacturing Institute (IEEE) released the semiconductor manufacturing field patent strength ranking, Seoul Semiconductor is the only elected LED manufacturing company, and after 2012, has been rated as LED field patent strength for two consecutive years. World number one.
The IEEE patent strength rankings selected by the IEEE each year are evaluated for the number of US patent applications, patent growth indicators, patent influences, and patent evaluation indexes held by more than 5,000 companies, universities, and government agencies around the world. Through this ranking, you can measure the technical strength of each company in its field.
Ki-bum Nam, deputy director of the Seoul Semiconductor Research Institute, said that "high-power LED technology is widely used in the entire LED field as a chip processing technology. It is the core patent technology that leads the future LED market. Recently, the LED field has infringed patents. The circulation of cottage products has increased dramatically, so we filed this lawsuit.†He emphasized that “in order to create a better and more convenient life, we must continue to introduce creative products; in order to achieve such ideals, we should take action to resolutely respond to patent infringement. The act of protecting intellectual property."
High power LED application field
(1) Car
According to the results of the market research agency HIS, the LED penetration rate for vehicles in 2016 was 16.4%, and it is expected to increase sharply to 32.3% by 2021. High-power LED technology has been successfully applied to exterior lighting such as automobile headlights and daytime running lights. In order to improve energy efficiency, it is expected to become an electric vehicle and driverless car that requires high-power, high-heat LED lighting technology. Required technology.
(2) IT
High-brightness mobile phone flash LEDs are also high-power LEDs. LEDs for flash lamps have higher profit margins than LEDs for backlighting, so although the growth rate of the entire IT sector is decreasing, it still maintains a growth trend. As the performance of mobile phone cameras has improved, the number of LEDs used has also increased.
(3) Lighting
High-power LED technology enhances the brightness per unit area of ​​the LED by improving the light efficiency of the power chip for illumination. It can be applied to outdoor lighting, commercial and industrial lighting with high requirements for light efficiency. It is expected that in the LED market for lighting, which accounts for half of the overall LED market, patent disputes related to high-power LED technology will further increase.
(4) UV LED
High-power LEDs are also suitable for UV LEDs with functions such as sterilization, purification, and curing. By 2020, the market size of UV LED applications is expected to increase dramatically to 800$M, so it will accelerate the application of high-power LED patent technology in the entire UV LED field.
Tension Compression Force Sensor
Miniature Force Sensor are designed for compression and tension and known for their small package size. They are used in tight and limited spaces. Miniature load cells are available in various capacities ranging from 5N to 200KN and in packages ranging from 8mm to 51mm OD. (can customized the Load Cell size) , the force sensors are widely used in Medical applications as well as automation where small size is a must and space is limited. If space is not an issue and higher precision is required then use a pancake style load cell. Rolling element bearing load measurement is an application where load buttons are utilized.
