Eye protection lamp
Composition of eye lamp (Zhongshan Huixin Lighting)
<SPAN title="" closure_uid_4iqtj8="32921" gd="“护眼灯”主要由单端荧光灯和灯具两部分组成。" ? hd="" parts. two of lamps and fluorescent single-ended the by mainly Eye?>"Eye" mainly by the single-ended fluorescent lamps and lamps of two parts. Single-capped fluorescent lamps for energy-saving lamps; lamps in the main electrical components are electronic ballasts and starters.
Eye protection works consisting of a lamp
More common in the Eye is currently working principle is to improve the high low strobe flash, using this Eye frequency electronic ballasts, the power frequency is increased to 5500H z 50H z to reduce flicker, the use of three primary colors phosphor, reducing the glare effect, making the soft light is not glaring, people do not feel the strobe eye discomfort, in order to reduce visual fatigue. Stroboscopic effect of fluorescent tubes is a test of all indicators: less flicker, lighting, the better.
Eye do eye it?
Although the fluorescent light emitted is white, but because it is from 50 Hz AC direct light, so the brightness of 100 times per second, the frequency of non-stop change, this is the stroboscopic phenomenon. Long hours under fluorescent lights flashing constantly learning, the eyes will feel tired. Incandescent light emitted compared with the natural light reddish rather than white light, this light will be black and white contrast of objects according to be reduced at the same time, as the light source, easy to produce harmful glare on visual acuity and large Yin Ying, a long time In this light, the eyes will feel tired.
However, the State Quality Supervision and Inspection Center and the lighting optic Fudan University Institute of test results is that the production of the Eye with high frequency ballasts, the strobe fluctuations in depth from 7.27 to 24.03% of the range, and no significant differences compared to incandescent, but strictly no flash strobe is the depth of less than 5% fluctuation, which means that no frequency did not meet the requirements. High strobe does not mean no flash, high-frequency fluorescent lamps should not use eye protection in the name of promotional products. Thus Eye is not no flash, just the number of strobe is high, the human eye can not tell, so I felt the same no strobe.
At the same time, high-frequency electronic ballasts for high-frequency oscillatory light on the human brain can produce extremely harmful electromagnetic radiation. Experts suggest that people should be maintained with the light from two meters. Electromagnetic radiation is classified as the world's fourth largest public nuisance is an indisputable fact, especially when used as Eye, from the head too close to the brain more likely to induce a series of hidden dangers.
Therefore, the real solution to electromagnetic radiation pollution in strobe lamps gradually by people concerned about the DC. DC fluorescent lamp will step down the mains into a DC rectifier, input a special lamp, avoiding the shocks generated by high frequency electromagnetic radiation and strobe can be said that a fundamental solution to the flicker problem. This technology has been
State Intellectual Property Office granted a patent certification.
The industry believes that the market as sort of a small light, large enterprises are unwilling to put too much financial and material resources, while the strength of small businesses have no money, so that current technology is not yet promotion. But for consumers, the most important thing is to use the real sound of the Eye Eye and buy a real Eye, do remember that high does not mean no strobe strobe.
Ordinary table lamp table lamp with the difference between eye
Ordinary lamp at 50 Hz alternating current state of work when the flash occurs 100 times per second or so, such a high flash rate, the human eye alone is not apparent. Therefore, under the lamp over time, plus do not pay attention with eye health, is extremely prone to myopia. The Eye of the principle of the electrical frequency of 50 Hz sucked up to 40,000 to 55,000 Hz, and the corresponding lamp will flicker frequency per second significant decline, and some can even drop to zero, thus helping protect the visual function. However, there are a lot of lighting market in the Eye of the quality of the brand, but related, Eye of the radio frequency internal quality requirements can not meet the requirements of more than 40,000 Hz.
