The so-called eye protection lamp mainly does not flicker. In the past, fluorescent lamps used inductive ballasts, and the lamps flashed at 100Hz. At present, almost all fluorescent lamps use electronic ballasts, and they can also be regarded as non-flicker and eye protection lamps without using the original inductive ballasts.
The traditional desk lamp is basically composed of a lamp holder and a cylindrical lampshade. Because the lampshade can concentrate light downward, the original function of the desk lamp is only lighting.
Working principle of eye protection lamp
Low frequency flash is improved to high frequency flash. This kind of eye protection lamp adopts frequency conversion electronic ballast, the electrical frequency is increased from 50Hz to 5500Hz, and the stroboscopic effect is reduced. The tricolor phosphor is used to reduce the glare effect, so that the light is mild and not harsh, and the human eye will not feel stroboscopic discomfort, thus reducing visual fatigue. Stroboscopic effect is a test index of all fluorescent tubes: the less stroboscopic, the better the lighting effect.
How about Kojiro desk lamp?
Kojiro desk lamp prevents myopia and protects the brain. 82Ra color rendering index, close to natural light. No radiation, no stroboscopic. It is a plurality of LED luminous units, and the light is very uniform. When students use it, they are intelligent and silent, undisturbed, and can study with peace of mind. In addition, the shape of Kojiro table lamp is fashionable and unique. The shape is simple and looks very textured. With this brand of desk lamp, eyes can be well protected.
Kojiro is famous for his healthy student lamp, which is used by Shenzhen Youshi Zhiyang Technology Co., Ltd.
human engineering
According to the specific learning situation of Chinese students at this stage, a special learning lamp for students is developed, which has no stroboscopic, radiation and glare, adopts microcomputer control, and integrates intelligent work and rest, intelligent dimming and intelligent mute functions.
Children's health has no fluorescent powder, will not produce ultraviolet rays, and will not burn eyes. There is no high-frequency electronic ballast in the lamp body, which will not produce high-frequency electromagnetic radiation, make people dizzy and slow to respond. At the same time, the student lamp uses LED light source, low-voltage DC, no stroboscopic at all, and will not cause dry eyes.
Xiao Erlang's healthy student lamp uses sidelight technology to process light, which will not produce glare and will not be dazzling when reading. , yes
Healthy lighting environment

Health, intelligence, environmental protection and people-oriented.
According to the study and reading habits of China students at this stage, the design concept of.
Fourth generation light source
Based on this, we will launch comprehensive and innovative learning lighting products.
Kojiro LED health lights provide ten health guarantees and achievements for children through three scientific and technological innovations.
Pioneer of student health light source
Reduce the burden on the eyes of China students nationwide, protect the body of China students from ultraviolet and infrared radiation, and let students experience a healthy and high-quality lifestyle while reading and studying efficiently.
What's the difference between eye protection lamp and children's health lamp?
According to the survey, the poor eyesight rate of Chinese students is 32.5% for primary school students, 59.4% for junior high school students, 77.3% for senior high school students and 80% for college students. Experts pointed out that 50-30000 flashes per second produced by traditional desk lamps and eye protection lamps are an important cause of myopia in children.
Students should study under the desk lamp for 3-5 hours every day. The child's head is only 30 cm away from the radiation source of the eye protection lamp, and the child's brain is completely covered by electromagnetic radiation.
Ultraviolet rays generated by eye protection lamps and infrared rays generated by traditional desk lamps will do harm to children's eyes over time when children study with desk lamps for 3-5 hours every day.
It can be seen that eye protection lamp is a killer that affects children's vision and brain development. And eye protection lamps. Almost every family in China has students. The emergence of Kojiro has only filled this loophole and made health coverage wider.
