First, choose the key points: In recent years, the increasing incidence of myopia in China’s youth, people continue to deepen their understanding of the importance of vision protection. The emergence of new eye-protection lamps in the market, so that learning lighting completely goodbye to the strobe, radiation, ultraviolet light and other optical pollution, become the majority of parents to help their children to protect the eyesight of the new eye protection shortcut. In order to children’s health in the purchase of eye protection lamps must understand clearly before buying, to avoid counter-consequences. At present, the table lamp commonly used in the family is mainly divided into incandescent, halogen and high-frequency fluorescent lamps, etc. Now from the following aspects to understand the selection of eye protection lamp points: eye protection performance: eye protection lamp to play a role in eye protection requirements: 1, to ensure the continuous stability of light, no strobe. In other words, the brightness of the light stability, no human eye perceptible, rapid changes in light and dark (i.e., strobe). 2, the lamp color rendering is good, light color close to natural. Color temperature in the 4000 to 4600K or so, moderate color temperature, soft light with a little yellow, more suitable for reading needs. Safety performance: the main requirement is that the power supply line, internal electronic lines have sufficient wire cross-sectional area and insulation layer thickness. The minimum distance between the positive and negative poles of the circuit board is greater than 2.5MM, there is overcurrent protection device, the light head switch in line with national requirements. Bad quality eye protection lamps do not meet the above requirements, which may lead to fire and child injury accidents. No electromagnetic radiation detection: the so-called electromagnetic radiation is the phenomenon of energy in the form of electromagnetic waves emitted from the radiation source into space. The flow of electric current in a conductor will produce an electric field, the current changes in the conductor will produce a magnetic field, so the radiation out called electromagnetic waves. Steady direct current does not produce electromagnetic radiation. No blue light: computers, TV screens, LED energy-saving lamps and other new artificial light sources emit visible light contains a large number of irregular frequency of high short-wave blue light, long-term blue light irradiation of the retina will produce free radicals, and these free radicals will lead to the decay of the retinal pigment epithelial cells, thus causing retinopathy and other ophthalmic diseases. At present, it is recommended that no strobe, no radiation, no blue light source of healthy table lamps. There are some brands of lamps on the market that meet the above requirements. Second, how to choose: when buying just pay attention to the following points on the line: to see the light: 1, brightness and stability, no flicker; 2, soft light; 3, more uniform light, not a very small point source; 4, lamps / lampshades are reasonably designed, no glare (eye can see the bright spot), some lampshades built-in lattice-like reflector, effectively reducing the contrast between the lighting area and non-lighting area. To see the documents: product certification, safety certificates to complete, to have the national safety compulsory certification mark CCC, often referred to as “3C” certification mark. Look at the product description, there is no strobe, electromagnetic radiation, blue light, etc.. To see the use and after-sales service: the use and maintenance methods should be easy, and must have the maintenance address and telephone. Third, the use of: on the one hand, the lampshade should be low to ensure that the gaze area light is bright enough to cover the light source to avoid glare; on the other hand, to avoid the lamp head too close to the gaze area (books / desktop), resulting in too bright light.
