On May 11, 2011, Dr. Shao Jiaping, General Manager and Technical Director of Cree China Market North, announced at GreenLighting's “Growing the Environmental Value of Solid State Lighting Products with Green Materials, Ecological Design and Recyclingâ€, today, Cree White light LED laboratory breakthrough efficiency of 231lm / W, breaking the industry's highest light efficiency record.
Dr. Shao Jiaping stressed that in addition to luminous efficiency, Cree also pays attention to other parameters, and Cree's light effect repeatedly breaks the highest light efficiency record, because Cree starts from the key core technologies of chips, phosphors and packages to fully ensure the light efficiency of LED devices. And quality. "The chip structure is different. It is necessary to study the packaging technology corresponding to different structures." Dr. Shao Jiaping said.
Similarly, different market segments have different LED performance requirements. For example, the commercial lighting market focuses on the color rendering index, and the parking lot focuses on reliability. LEDs should be optimized according to application requirements to facilitate terminal design and application.
Dr. Shao Jiaping said that the current global lighting is about 80 billion US dollars (including electronic components such as light source / lamp / ballast), LED semiconductor lighting proportion is only about 5%, and the expected ratio in 2015 will rise to about 50%. At that time, LED SSL is expected. Become a global industry with more than $50 billion. China has the world's largest traditional light source and lighting manufacturing base, and the lighting segment is complete. The global LED SSL development focus is on China, but Chinese companies must complete the transition from “manufacturing†to “intellectual creationâ€.
