Does LED table light really protect our eyes
Lighting making effects on vision mainly reflect in these areas : Strobe , UV , color rendering index . CCTV10 science program has tested a variety of lighting effects for the visual level , the results show : no flicker , no UV , color up to 90 or more, indicating the T5 LED as eye care products seems to be perfect , is this really ?T5 LED T8 LED led fluorescent Tube
T8 LED as the table lamp is actually not suitable. Lighting Research Institute of Fudan University have tested a lot of table lights for reading on the domestic market recent years，what they have found that there are large number of blue led fluorescent Tube , which is not conducive to eyesight. In addition to Blu-ray problem , the common problems led fluorescent Tube lamp products arose a few years ago were insufficient flux , low light ; addition, in terms of color , the color is distortion when we see things under the LED table lamp ; at the same time, just very small portion can be shined, which is called the light -shaped distribution inappropriate ; and the emitting point of LED table lamp is lighter , which it still feel very dazzling when we stare, the eyes will feel very uncomfortable. Currently, the state don’t publish a uniform standard for the T8 LED table lights, some of the very inferior LED table lamp is actually no good for the eyes . Therefore, in addition to individual particularly good quality product , and can not play a very good eye protection .
For the vision , not only being affected by the light that is the single factor , in fact, also by other factors . Now what the reasons widely recognized that cause myopia are: one , genetic factors, especially the patients with high myopia . 2 , growth factors , the curvature of the lens of the eye has been long and gradually become larger with age , if overgrown , the axial gradually lengthens , forming the myopia. 3 , environmental factors , which is the main reason causing many of today’s myopic patients . Myopia gradually increase among the young students , which is inseparable from more and more advanced technology product in today’s society . Juvenile myopia is mainly caused by today’s long watching TV, the Internet, play video games and other causes do not paying attention to eye, of course, but also because of reading, writing posture, books put too close from the eyes , or poor lighting conditions and other causes . These will cause ciliary muscle sustained contracted , the F degrees of lens grow within the ciliary muscle tensing , variable F of the lens be restored to its normal state, thus resulting in a pseudo-myopia. If you still do not pay attention to take effective preventive measures at this time , it will become true myopia. 4 , other factors such as changes in nutrients . Therefore, the prevention of myopia do not just change the lighting , but more and more other causes should start so that make our eyes better !
Because LED table lamps are sleek and stylish products , so for T8 LED table lamps, most consumers still like to go online shopping, especially some young student groups. The problem is that some existing Taobao sellers guise the LED table lights and one-sided propaganda and over- inflate the price of their products , the same one LED desk lamp has been sold $ 30 , also 300 yuan , it is very easy to feel confused in choosing aspect for consumers，It is not worthwhile to choose the dear，but they are afraid of not good goods if choosing the cheaper. Most sellers on Taobao publicity the Eye -based LED table lamps, but there are a few sellers deceive that LED table lamps are able to prevent the myopia and protect the eye, its price is higher than the that of the same LED lamps, this over- exaggerated value results in pitiful sales. For how to choose the LED table lamps , personal recommendations is choose the right but not to choose expensive.
In addition the LED table light stepping into our daily life，there are kinds of LED light especially the RGB LED flood light is the most widely used as the representatives of the decorative lighting and the public lighting around us, the RGB LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. whereever needing the brighter and colorful illumination,meanwhile，there are a large number of factory engaging in developing and producing the RGB LED flood light，Lead Lighting is just one of them，which adopts high brightness COB as the light source of the RGB LED flood light so that fully guaranteed octahedron breadth and bright irradiation range of the RGB LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of RGB LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and polluting the environment, that’s why the LED light is Known as energy-saving and environmental protection.
