The fermentation of health issues has contributed to the emergence of purple LEDs. According to many studies, light has a great impact on human sleep patterns and health. When exposed to LED lights with blue light at night, it may have a negative impact on sleep and long-term health. In order to solve this problem, the violet LED has the characteristics of copying natural light time and visible light spectrum, and can automatically adapt to the environment according to sunrise and sunset time, adjust user habits, and create a new healthy living environment. Nobel Prize-winning physicist Nakamura said that lighting affects many health problems. Blu-ray will inhibit the release of melatonin in the brain and block drowsiness. As long as there is enough blue light around the eyes to stimulate the eyes, there is a chance to stop releasing melatonin and produce sleep. Quality and myopia problems, and these problems are not the problem with early natural light sources. Nakamura said that more and more medical experts have begun to notice the impact of different wavelengths of illumination on human health. It is expected to know which wavelength or color of LED has health effects, and further control LEDs in different wavelengths. Control or avoid damage caused by blue light to the human body. Lin Gongru, director of the Institute of Optoelectronics and Motors of Taiwan University, added that in order to effectively isolate the harm of blue light to the human body, Nakamura Shuji replaced the blue LED with a violet LED, and added a phosphor to the violet LED to make a color temperature close to the sunlight. This technology can minimize eye damage. Since the wavelength of the blue LED just hurts the human eye, there are many lighting source specifications that set some standards to limit the residual power of the blue component in the illumination source. The violet LED technology can completely avoid the damage to the human eye. Blu-ray band. Nakamura said that Soraa has begun mass production of violet LEDs, which are used in the field of home intelligent lighting. It can automatically adjust the conversion of blue and violet light. For example, in the morning, blue light is used to wake people up, when the sun goes down, through Soraa's patented BlueFree LED technology. The blue light is completely removed, while retaining the beautiful soft white. A typical smart light bulb can change color during the day and night, but since they are made of standard LEDs, they emit up to 20 times more blue light. Conversely, violet LEDs can illuminate the perimeter without affecting color. In addition to Soraa, manufacturers in Japan have begun to use purple LEDs for mass production, and Taiwan's LED manufacturers have quietly launched a series of layouts. Nakamura said that the violet LED can be widely used in every corner of daily life, but it is currently limited by price considerations and has not yet been widely used in the market. He said that the use of gallium nitride (GaN) substrates in violet LEDs is needed to improve the quality and performance of LEDs. However, the cost of GaN substrates is expensive, so the output and price of violet LEDs are still high. However, at this stage, as production increases, supply should become increasingly popular and further reduce overall prices.
