Korean manufacturers including Samsung, LG, Seoul Semiconductor, Woree and Lumens were huddled in Hall 6 of Light + Building 2014 show that recently took place in Frankfurt, Germany. These Korean manufacturers displayed their latest LED packages, LED smart controllers, and new OLED products.
Samsung’s booth design was similar to the display industry and heavily relied on displays. The company used a large number of transparent displays again this year to highlight products, giving the booth an overall high-tech vibe. The booth was segmented into two display areas one for advanced LED technology, and the other for LED lighting product development.
Another major Korean manufacturer LG displayed different applications and division of work in Hall 6 of the lighting fair. LG Innotek displayed different types of LED components, LG Chem showcased OLED related applications, while different lighting applications were shown at LG Electronics.
Seoul semiconductor displayed LEDs for different application fields including LED components for automotive lighting. The company highlighted both low power LED and its Acrich series LED, which included 4 to 12W AC LED modules. Since Acrich modules are LED products that can be directly plugged in or unplugged without the use of converters, the products long lifetime, and convenient designs are quite evident.
Korean manufacturer Lumens also displayed very competitive LED components at the show this year. Especially the company’s Eragon series flip chips, which incorporate silver free technology. In general to increase luminous efficacy, flip chips are coated with silver material that functions as a reflective layer. However, the silver coated layer has a tendency of oxidizing when moved or dislocated, which can cause color deviations in LEDs. Lumens silver free technology can prevent this from happening.
