Seoul semiconductor develops new LED technology to return led to nature

Abstract: combined with Seoul semiconductor LED chip patent technology and Toshiba materials tri-r phosphor technology, sunlike series can provide the industry's best quality light source for the new generation of LED products, making people-centered lighting suitable for circadian rhythm

Seoul semiconductor, the innovator of global LED products and technologies, has developed a new LED technology, which produces light close to the natural light spectrum. On June 26, 2017, Seoul semiconductor announced this at a press conference held in Frankfurt, Germany. The new sunlike series natural spectrum LED technology was jointly developed by Seoul semiconductor and Toshiba materials

return to natural light

human beings lived in the sun for thousands of years, and did not use lanterns until the third century BC. However, white LED has been used in general lighting for less than 20 years, but due to its high luminous efficiency and cost saving characteristics, LED lighting has been widely used all over the world. However, compared with light quality, low cost and brightness are given priority, so the characteristics of light generated by traditional LEDs are different from natural light that conforms to human biological rhythm

sunlike series LED technology is close to the spectrum of natural light that human beings have enjoyed for thousands of years. It maximizes the advantages of natural light and minimizes the disadvantages of artificial light sources. The light produced is more like natural light. By combining the world's top LED chip technology of Seoul semiconductor and Toshiba materials tri-r Technology (the world's leading technology to enhance competitiveness? Leveraging the university to establish a research institute phosphor technology), the natural light spectrum is realized

mr. kumpei Kobayashi, CEO of Toshiba materials, said that he was very happy to cooperate with Seoul semiconductor, a global LED leading enterprise, to launch sunlike series natural spectrum led, which represents an advanced technology and can create a more intimate and natural lighting environment

Mr. Lee Jung hoon, CEO of Seoul semiconductor, also said that it is a great honor to introduce another Korean innovative LED technology sunlike series LED lighting technology, which produces light close to the natural light spectrum. Just like our packaging free wicop series completely changes the LED packaging process, our sunlike series represents a new revolution in creating natural light LED lighting. He also added that sunlike series LEDs will be used in the field of lighting, aiming to provide humans with a better and healthier life. They are also suitable for gardening lighting, creating an ideal environment to help plants grow, which is safer than using genetic modification

he also said: "We are very happy to cooperate with Toshiba materials to provide customers with light sources that transmit natural light - from the first ray of sunlight in the morning to the sunlight that brings vitality, and then to the warmth of the sunset in the evening. We believe that sunlike series LEDs have successfully won the bid for the construction project of the national demonstration platform for the production and utilization of new materials, which will improve the quality of human life by promoting the arrival of a new era of people-centered lighting.

minimize the side effects of blue light

sunl Ike series LEDs are designed to transmit light close to the natural spectrum, so they provide an optimized light source for human centered lighting, maximize the advantages of natural light, and minimize the negative effects of artificial light sources

some recent studies from Harvard University and other major universities have shown that blue LED chips used in most commercial lighting will produce visible light, which will bring positive stimulation to the human eye during daytime viewing, thereby increasing alertness and improving mood. However, these blue LEDs will produce blue light "peak" in the light output. If you watch them for a long time at night, it will have a negative impact by interfering with the biological rhythm of the natural human body. Sunlike series natural spectrum LED technology adopts a kind of purple led, which is combined with tri-r phosphor technology to minimize the "peak" of blue light (which is the characteristic of typical LED light source), so that the generated light is close to the natural light spectrum and brings a healthier light experience

according to the research results published in academic journals such as nature, human beings have lived in the sun for thousands of years, and human organs and biological rhythms have evolved to make the most appropriate response to natural light. Human retinal cells (which interpret and respond to color related light input) are composed of red, blue and green cone cells, while the proportion of cells that recognize blue is only 5.7%

Figure 2: only 5.7% of S-cone in optic membrane cells can distinguish blue

the amount of blue light that our eyes can accept is limited. If blue light exceeds the limit, it will be scattered into the eyes. When scattering occurs, light will diffuse, so the texture and color of the object will be distorted. In addition, too much blue light will over stimulate the retinal cells in the eyes, which may lead to eye fatigue and inattention. However, because sunlike series LEDs achieve the spectrum closest to natural light, they can more accurately present the color and structure of objects in natural light, avoiding the negative impact of excessive blue light on the eyes or human biological rhythm. Many products using Toshiba tri-r technology have been used in Milan Fashion Week lighting and installed in museums to illuminate art works

Application and market forecast

sunlike will be mainly used in commercial facilities that need to identify or display the exact color of the items they see in the sun, such as department stores, boutique jewelry, gardening facilities for indoor plants, exhibition facilities such as museums, exhibition halls, beauty facilities such as dressing rooms, bathrooms

the global lighting market is estimated to be $87billion, of which led lighting accounts for $35billion. In the LED market, the overall share of sunlike series LEDs that can be applied is US $17billion. It is expected that sunlike series natural spectrum LEDs will initially be applied to lamps requiring high-quality lighting, and eventually enter the general lighting market
