How to choose a suitable desk lamp for your child?

There’re 3 potential bad influences that traditional desk lamp have on human health: strobe light, electromagnetic radiation and light glare.

  Strobe light

A strobe or a strobe light is a very bright light which flashes on and off very quickly, like incandescent lamp, energy saving bulb lamp. As human’s neurotransmission is slower than optical electricity in flashing frequency, thus we can’t see the flicker of light source with naked eyes. Optical electronic photographic camera equipment like a mobile phone camera or tablet camera helps easy to see the strobe light.

When you’re buying a lamp, put your mobile phone camera close to the illuminant. If the screen shows rolling stripe image, then it turns to be strobe light. If there’s no rolling stripe, the illuminant of the lamp is stable, that is, no flicker. Many people think the flashing or blinking does not exist when they can’t see with eyes, yet in fact it is brain’s illusion that we don’t see the strobe. The information of the strobe isn’t transmitted to the brain, so the brain isn’t able to make a judgment about strobe. It is like after watching a traditional movie, many people feel their eyes are very tired. This is because the strobe pictures produced by the high-speed projector make the eyes constantly in motion, resulting in prolonged eye muscle fatigue and a sore painful feeling. That is how strobe light of desk lamp works. Children has a weaker durability of the eye muscle than adults, thus when they study under the strobe light for hours, they may get very tired in the eyes and feel sleepy, which often leads to myopia.

Therefore, an eye-protected desk lamp of no flashing strobe light is necessary for children. It can extend the time getting tired of the eyes and help forming good sitting posture and prevent pseudo myopia.

  Electromagnetic radiation

We all know that if electricity pass through a metal wire, electromagnetic field will be formed. Light source like desk lamp can also produce electromagnetic field, the so-called radiation. A desk lamp has radiation just as a mobile phone does. Only the frequency is different. Desk lamp radiation is of low and intermediate frequency, while mobile phone and microwave ovens are of high. High frequency radiation can penetrate human body. Low and intermediate frequency can be absorbed by the body. The electromagnetic radiation

that a desk lamp releases will not produce heating effect like a microwave due to the low power rate. But the radiation energy that accumulate in the body will affect the normal development of the body, like hormone secretion, endocrine disruptors, the human body magnetic field, even offspring genes.

Desk lamp without radiation won’t do harm to human health. Then which kind of table lamp has radiation and which one doesn’t? Electric appliance with two phase power plug will release electromagnetic radiation under electric condition. Keep 0.5 meter away from it would be better. Three phase power plug may not have radiation release, for the radiation could be separated by circuit and conducted to the ground. That depends on whether the appliance has the function of separating and conducting the radiation energy. As electromagnetic radiation is invisible, only detector can tell if there is radiation. A detection pen is a good helper for you to test the radiation when buying a lamp and it is not very expensive.

  Light glare

Light glare is very bright dazzling light. In general, teenager is much more sensible to light environment than adults. So never use your experience about lighting when you buy a desk lamp for your child. Light environment of high brightness will make the pupil contract. Contracted pupil shows the eye muscle is in tension. If the eye muscle strength need to be reduced, the light should be dimmer, thus the dilation of the pupil can ease the fatigue. Desk lamp for learning and reading should be able to adjust the brightness. Parents can guide the children to select the suitable lamp.

  LONEN new type desk lamp SP02-15

LONEN SP02-15 is rechargeable LED desk lamp with 40 energy saving and eyes-protected SMD LED bulbs. LED is new type of light source and with filtered processing it can be applied in reading lamp. The light is dimmable, cold and warm light can be interchanged by a knob switch to meet different needs. Except for that, this desk lamp has FM radio function. After lots of hard work and study, you can turn on the radio and get relaxed and entertained, isn’t it a lovely and humanized design? I believe when you get the zebra lamp, you just don’t want to put it down!
