How to judge whether household desk lamps are conducive to vision protection, desk lamp manufacturers give you a brief analysis

The Guidelines put forward that home lighting sources need to use three primary color light sources, red, green and blue are the three basic colors, three primary color lighting equipment has the characteristics of soft luminescence, uniform brightness, no flicker, no dazzling, etc., so it is widely used in school and home lighting equipment. Color temperature can be measured with color temperature agent, what should we do if we don't have color temperature agent? General product manual will mark the type of light source, color temperature, illuminance, strobe these basic parameters, in the family, we can also use some color temperature comparison chart, is we often see the red orange yellow green order of the diagram, the color of the light and the lamp color temperature has a relationship, the color temperature will be too white, too dazzling, low color temperature tends to yellow-red, easy to cause sleep. At home is very good to judge, if the light is yellow-red, its color temperature is low, the sunlight of an hour after sunrise is about 4000k concept, about 4000k color temperature will make people have a warm feeling in wakefulness.
Just talked about the low color temperature tends to yellow-red, the color of candlelight has 2000k color temperature, just talked about the color temperature of about 4000k an hour after sunrise, reading and learning at this color temperature, peace of mind, high learning efficiency. Therefore, it is recommended that the color temperature of the desk lamp for children's reading and learning should not exceed 4000K. At present, some desk lamps on the market have a high color temperature, which has a damaging effect on the retina, which will lead to macular degeneration, increased free radicals, and is also a risk factor for myopia. At the same time, use at night will inhibit the secretion of melatonin, interfere with the biological clock, and be detrimental to the child's physical and mental development. Therefore, we repeatedly emphasize that the desk lamp for children's learning should have a color temperature below 4000K. Parents go home to check what the color temperature of the desk lamp used by the child is, and if the light source used does not meet the requirements, it should be replaced as soon as possible. At the same time, parents are also reminded that if the ceiling light of the room where we study does not meet the relevant requirements and is not a three-color light source, it should also be replaced as soon as possible.
