Seoul Semiconductor to mass produce filament LEDs

February 15, 2017 // By Julien Happich
Holding hundreds of patents for filament LEDs, covering chip manufacturing, COB-packaging, module and bulb manufacturing processes, Seoul Semiconductor announced it is now starting the mass production of its LED Chip-On-Board Package for use in LED filament bulbs.

“Based on its strong patents, Seoul Semiconductor will continue to increase its market share in the filament LED bulb market, which is a blue ocean market estimated at $1.3 billion”, stated Mr. Ki-bum Nam, CTO of Seoul Semiconductor, adding “We will widely promote the superiority of Seoul Semiconductor’s LED technology with its filament LEDs.”

Being omnidirectional and combining a small footprint with a wide beam angle, the filament LEDs boast a Colour Rendering Index (CRI) better than 80 and can output between 105 and 210 lumens at Correlated Colour Temperature (CCT) of 2,700 K. The company which started developing the technology in the early 2000s has established a strong IP portfolio around all the core technologies for the manufacture of filament LEDs and it is now hoping to reap the benefits of its investments.

“We are readying legal actions, as many of the LED bulbs released in the market have infringed our proprietary technologies” said the company in a statement.
