Without falling wood Xiao Xiao - LED lighting will be the trend of the blowout into the homes of ordinary people

The brightness of came 130 incandescent bulbs per watt energy only produces 15 lumens, fluorescent lamps and 60 years ago, the energy efficiency is up to now 60 to 90 lumens per watt, but besides saving energy, many disadvantages and problems may also worthy of attention: classroom lighting "my kids are in school for more than a year, vision decreased significantly, this is a careful mother of the child vision concerns, she always thought was reading posture problems, but has recently learned that the school is the lighting environment caused by the unscientific. The results show that the myopia rate of primary school students in China is 26.96%, and that of middle school students is higher than that of the middle school students. The results show that the rate of myopia in primary and middle school students in China is about 53.43%, and that of high school students is over 72%. At present, the problem of small and medium-sized Chinese eyesight students has caused widespread concern in the lighting of the experts and scholars, believe that in addition to learning burden, eye health and light environment is also an important reason can not be ignored.

Expert advice: in the classroom lighting light source selection, should be about 4000K medium temperature led as the main light source. The high and low color temperature light source can increase the students' brain fatigue and visual fatigue, reduce the learning efficiency, and should not be used as the main light source.

Shopping lighting

According to media reports, some Nanjing people got in the eleven holiday in a strange, as long as the mall will feel dizziness, chest tightness, physical discomfort, and this feeling intensified as the shopping time growth, but as long as out of the mall after the symptoms will disappear automatically. After the analysis of the reasons for the emergence of these symptoms of health experts, in addition to the crowd density is too large, poor ventilation, shopping malls energy-saving lamps of ultraviolet light, strobe, electromagnetic radiation is also an important reason. The original culprit is the energy-saving lamp, fluorescent lamp is formed by ultraviolet light as everyone knows mercury vapor, with UV excited phosphor luminescence spectra, there will be intermittent tip with strobe, electromagnetic radiation is harmful to health problems. And LED lamp backlight module is the application of high-end technology, the LED point light source through the refraction and reflection of light, diffusion, make it become uniform and soft light ray surface, and the distribution range of the light intensity distribution curve in the design of the control range, which does not produce glare. Face practical problems in life I list some fragmentary knowledge about the traditional energy-saving lamp and LED lamp to readers. , energy-saving lamp luminous principle is mercury vapor excited and light, so each energy-saving lamps are mercury. Even according to the latest European environmental standards, an energy-saving lamp mercury content is about 3--5 mg. Once broken, only 3 mg will be about 1000 tons of water pollution, 300 cubic meters of air! It is predicted that this century will be the prevalence of mental illness, because mercury poisoning is mainly damaged nerves. LED solid light source, no mercury and harmful gas, so no pollution to the environment. Two, China Medical University Institute of Dermatology and Cosmetology research shows that, under fluorescent light a day of study absorbed UV exposure in the sun quite an hour. Ultraviolet radiation will directly destroy the body's immune system, killing white blood cells, damage the chemical bonds of nucleic acids and proteins, cause genetic variation (DNA), and even cancer. LED lighting is no UV radiation source, not to lure mosquitoes, not only healthy and clean health, is the first choice Home Furnishing lighting. Three, the European Commission on illumination (EuropeanCommission) issued the "90/270/EC guidelines", stressed the need to solve and reduce the stroboscopic effect of lamps, to solve the people caused by migraine and visual nervous system lesions. China's civil alternating current is 50HZ per second, fluorescent lamp light flashes 50 times, in the flashing lights below for a long time people prone to myopia (we can think: from the vegetable oil lamp, kerosene lamp to incandescent lamp, fluorescent lamp, lighting brightness gradually improved, and the vision of young people has declined year by year, and younger age the degree also increased.) ; moving objects will appear ghosting phenomenon, such as the stadium can use fluorescent lamps, especially like table tennis, badminton ball in fluorescence under the lamp can hardly match, rotating machine workshop will make human eye reversal or static illusion in fluorescent lighting, which led to the accident occurrence. LED lamp with low voltage DC power supply, there is no power supply voltage periodically changed, so there is no stroboscopic effect, eliminate the visual damage caused by traditional strobe light, is now recognized as the vision, especially the vision of young people healthy lighting. Four, the energy-saving lamps and computer, mobile phone, when will the outgoing electromagnetic radiation, according to the British Medical Research Center, University of Cambridge, Vienna headquarters of the International Commission on illumination research shows that electromagnetic radiation may cause heart palpitations, insomnia, white blood cell, reduce memory loss, cardiovascular and other organs and nerves the system is damaged, and the electromagnetic radiation damage is cumulative. LED light source at DC / low state, no electromagnetic radiation, will not be formed on the human body electromagnetic radiation damage. LED lighting also some produced using patented LED high power supply, and is suitable for high voltage power supply, universal (85V-280V) ensure the life and brightness is not influenced by the voltage fluctuation, the electro-optical power conversion close to 100%, more than 120LM/W luminous efficiency than incandescent lamp, save electricity more than 92%, compared with the traditional energy-saving lamp energy saving 80%, with a life span of 15 years, greatly reducing the source of replacement and maintenance costs, and the current price
