How to choose the safe and reliable LED lampsLED as an efficient and green new way of lighting is getting closer to our homes. However,because of the particularity of the manufacturing process, the LED lights emits a stronger blue light. The Internet rumors that if the Blu-ray content exceeds a certain limit, it is possible to adversely affect human vision and biological rhythms. So, the market blue LED lamps cause harm to humans or not? How to choose a safe and reliable LED lamps? The Evaluation Department of Shanghai Semiconductor Lighting Engineering Research Center Qian Wenlei introduced that the so-called blue refers to the visible light wavelength of 435 nm to 480 nm section. LED lamps due to the current technical solution is the most commonly lue chip + yellow phosphor?on the market, making that the blue LED lights has the relatively high concentration. Medical studies have shown that too much blue can cause photochemical damage the retina, but also affect human melatonin secretion, disrupt the biological clock. However, this does not mean that LED light fixtures is more injury eye than others. Experts do better than in the experiment, the LED lights having the same color temperature is almost indifferent with security of energy-saving lamps. The so-called color temperature indicates the most common targets of light spectral quality. Ordinary people call the arm glow?whose color temperature is low, while the old?color temperature is relatively high. the proportion of blue radiation doesn increases until the color temperature is raised, which may result in an increase in blue. Another factor affecting the proportion of blue light is the brightness, in general, the brightness of the fluorescent lamps and LED lamps having the same color temperature is different as long as the latter is three times more than the former, substantially no harm. But the individual LED lamps is too bright, its blue proportion may exceed the safe value. Lighting Research Institute of Fudan University, deputy director Zhang Shanrui said, with the LED technology matures, manufacturers no longer need to blindly increase the color temperature of lighting and power to achieve high lumens, which objectively also reduces the possibility of the excessive blue. In fact, either it is LED lights, energy saving lamps, or uba?used in the bathroom, which are likely to exist Blu-ray excess problem. At present, the international community has uniform safety standards for the light blue, ZhejiangUniversity, Professor Mou Tongsheng revealed that China latest standards will also be released in 2014. As long as strictly implement the relevant standards to produce LED lamps, the general public can rest assured to buy. According to reports, the industry set classification system to blue light hazard. The safest is 0, the lowest the blue is Highest risk is 3. The general LED lamps using indoor are in the range 0 -1 level, while two or more lamps will use the label to indicate in the future. How to buy lamps for the public, the experts also have Weapon. For example, when purchasing indoor LED lighting, we better try to choose a diffusion cover or diffuser plate, the chip can not be seen directly, but Luminous point should not be too concentrated; purchasing Yuba, the best choice is that the color temperature is not higher than 2200k (Kelvin), generally speaking, the color temperature of ubular?Yuba is lower than the ulb-shaped?Yuba, Blu-ray safety factor is also higher. The lead lighting adopts reasonable lighting design and high brightness SMD LED as light source to better protect that the light of the LED tube light as the main indoor lighting is soft and non-glare, the blue is below the standard level, and PC cover, PC boards, aluminum heat sink ensure the light is natural and has good heat dissipation characteristics, PC cover has the advantages of high transmittance, anti-glare, anti-UV, resist impact, aluminum shell of the LED tube light is made of high-purity aluminum by anodic oxidation, the appearance is simple and fashion and has never changed color, the LED tube light has good heat dissipation and can be easily operated and instant started, it has no flickering, no humming, lead, mercury and other hazardous substances so that significantly reduce the flickering and strobe that irritate our eye s and is caused by instability voltage to ensure that we learn and work more comfortably, log in to learn about more comprehensive LED tube light. ...
