LED hidden 'blue'

Since the village two developed efficient blue LED technology, LED lighting on a path to commercialization, real into the era of popularization of LED lighting. The energy conservation and environmental protection light source on the human environment have a huge impact, if all the lighting lamps and lanterns is replaced with LED lights, annual global saving at least



since nakamura to fix two 【 Nakamura 2 ( 认Nakamura) , was born on May 22, 1954, the Japanese Iraqi town, graduated from tokushima university in Japan, Japanese, American, electronic engineers at the university of California, Santa Barbara in the college of engineering materials, professor. 】 The development of efficient blue LED technology, LED lighting 领导( LightingEmittingDiode) That is led lighting, lighting is a solid light-emitting semiconductor devices. 】 Really on a path to commercialization, into the era of popularization of LED lighting. The energy conservation and environmental protection light source on the human environment have a huge impact, if all the lighting lamps and lanterns is replaced with LED lights, save electricity at least 1. 52 trillion KWH, around the world each year can decrease at least 500 million tons of coal, reduce carbon dioxide [ Carbon dioxide, chemical formula: CO2, it is common greenhouse gases in the air, is a kind of gaseous compounds, carbon and oxygen reaction generates its chemical formula for CO2, a carbon dioxide molecule consists of two oxygen atoms by covalent bonds with a carbon atoms. 】 Emissions of 1. 3 billion tons, reduce sulfur dioxide [ Sulfur dioxide ( Chemical formula SO2) Is the most common and simple sulfur oxides. 】 Emissions of 4. 2 million tons. Also, LED intelligent control and using range of attributes, is the future Internet of things' Internet is an important part of a new generation of information technology, is also the important stage of development of the 'information age'. 】 Age, wisdom city' Wisdom city is to use information and communication technology to sensor, analysis, integration of city core system running in all kinds of key information, and including the people's livelihood, environmental protection, public security, urban services, commercial and industrial activities, all kinds of requirements to make intelligent response. 】 The best carrier, thus gradually by the Internet giant of science and technology. LED to the development of the momentum is fierce, but its 'blue' blu-ray harm' 。 To distinguish between blue light damage and 'blue' lighting affects SiChen rhythms of the two different situations, usually using the UIV OLED lighting panels technology to suppress the blu-ray. 】 In recent years, many opinion in inside and outside. Study says, because the blue light peak wavelength of radiation and retinal blu-ray body damage characteristic curve and non-visual photosensitive curve with larger overlap, so too much blue used in indoor lighting, to people's physical, psychological and optic nerve, etc. A series of influence. It is on the vision, the LED the blue light can penetrate the lens to the retina, the retinal photochemical damage, accelerate the oxidation of the macular area cell, cause vision loss, degree of cataract, blindness and other eye diseases; Second, biological effects, in white LED a lot of blue light to the inhibition of melatonin, will result in a sleep disorder, and a series of dysfunction. At home and abroad the latest study showed that the quality of its spectrum 'blue' easy to affect the person's SiChen rhythm, thus reducing immunity. In addition, the LED industry after recent years of rapid development, the performance is improved, the industrialization LED light efficiency can reach 239 lm/W, far more than the application in the field of lighting requirements. However, in the field of general LED lighting pursuit of high photosynthetic efficiency, high color temperature virtually has also increased the harm of 'blue', people paid attention to the pursuit of quality of light.
