Luminus Announces Leadership Transition as CEO, Dr. Sun Retires

Luminus Devices announces that after 11 years of service, Chief Executive Officer Dr. Decai Sun, is retiring, and Mark Pugh, currently the Executive Vice President of Marketing and Sales at Luminus, will take over the CEO role immediately.

Dr. Sun started Lightera Corporation in Silicon Valley in 2012 with funding from Sanan Opto. Lightera Corporation quickly acquired Luminus in 2013, merging the two companies with Dr. Sun becoming its CEO.  Under Dr. Sun’s leadership, Luminus became a profitable, well-known LED component company achieving success in a broad range of applications worldwide. He moved Luminus from Boston to Sunnyvale in 2014 and recently built the worldwide team to more than 200 employees.

Mark Pugh has been a well known pioneer in the optoelectronics industry for over 30 years with leadership roles in business development, marketing, and executive management. His career started with Hewlett Packard in the Optoelectronics Division working with LEDs and infrared devices. This eventually led to an opportunity to represent HP in a new joint venture with Philips that later became Lumileds. In 2007, Mark co-founded Xicato with the goal to replace halogen lights with LED modules that had industry-leading quality of-light and all the benefits of LEDs. In 2015, Mark joined Luminus Devices as Executive VP of Marketing and Sales, and the company quickly tripled in sales and turned profitable.  Mark shares his vision for Luminus, “We will continue to further expand our broad product offering of photonics solutions as well as leverage our Sanan group relationship to grow our customer base in new markets with new and compelling semiconductor technologies.”
