- Q: LED bulbs can put in the desk lamp of adjustable brightness?
- can But there is a very troublesome problem stroboscopic Normal LED dedicated power supply, are constant current And the frequency to more than 100 hz Standard of 50 hz power frequency electric, will have a stroboscopic Some leds obviously, some is not obvious But even if is not obvious, after a long time also feel dizziness, eye fatigue
- Q: The lights suddenly not at home this evening! Can't say no! There are several have a little light! Feeling superior and see what's going on! Light bought less than half a year! The following two pictures were taken by the night!
- Estimation is very cheap LED lamps and lanterns, can the quality of the LED lamp bead is not good, plus if the power part is a simple RC step-down, will lead to the LED lamp bead aging droop failure quickly. Only buy a new one, don't be anxious to get things on the cheap goods.
- Q: LED rechargeable lamp charging is better
- Use light not too bright in charge, charge when there is electricity affect battery life. Nor the electricity used all forms a discharge, also affect the service life of the battery, for the average user is not very good, can only be felt light and dark in charge.
- Q: The child for LED the desk lamp that shield an eye myopia?
- LED the desk lamp that shield an eye is no ordinary incandescent lamp flickering phenomenon, comfortable and protect the human eye. Myopic children, of course, you can use.
- Q: I had had a 20 leds rechargeable lamp, then search the battery is broken, I version removed yourself to make the lamp, can directly use electrical appliances, please start
- The desk lamp of you already can charge (should be 220 v) you can directly with charging power supply should be bright?
- Q: The principle of LED the desk lamp that shield an eye
- The desk lamp that shield an eye is the use of no flicker, no stroboscopic, eye fatigue, not all metal texture, elegant, classic. Using high brightness and low light failure LED strips, low voltage DC12V switch type constant current drive, no stroboscopic, no radiation. Unique polarized light membrane technology, can make the LED light uniform directional output, not glare dazzling, the prevention of myopia. LED lighting now has entered the new era, a large number of LED lighting products into the family, such as LED lights, LED lights and LED desk lamp and so on family, but still have to remind the LED lighting use less as far as possible, there are blue, especially the LED the lamp that shield an eye in the trial period, LED for auxiliary lighting. Only. There are a lot of energy levels of electrons in an atom, when electrons from high level to low level transition, electron energy is reduced, and reduce the energy into a photon emission. A lot of these photons is the laser
- Q: Led lamp generally not transformer, why also said some led desk lamp radiation levels
- There will be no frequency transformers high-frequency transformer (a lot of switch power supply are to be used), and high frequency transformer has radiation. If there is a low frequency transformer (it does not need to high-frequency transformer) but not excessive radiation
- Q: Heard that LED save electricity, to follow the fashion, a grind, spent more than three hundred bought 6 LED bulbs, but less than 3 months finished bad, all manufacturers attitude can also, all changed, but also bad, depressed.
- LED drive circuit, the chip is the key to LED lights, if more than 50 bulbs also do a little wrong, so reach the technical level of domestic some manufacturer, made in the country that is imported, it is better to buy some export brand. Some of taobao mall just can also, this price can buy good LED bulbs
- Q: Are led lamps good for eyes
- Second, from the Angle of the optical to see: Traditional light source, and at the same time issued a red wavelengths of light, you can understand as invisible infrared, the over 780 - nm wavelength radiation can cause damage to the eyes, myopia are mostly indoors for a long time, too much rely on under the traditional lighting light caused by the work and study. And LED light source, mainly is the blue chip inspire yellow phosphor, the wavelength of light in between 380-780 nm, no ultraviolet and infrared light, good LED light source (note is good, you usually see in stores outside does not conform to the mostly, the current domestic exports have all the good) color rendering index greater than 85 (color rendering index, the higher the more close to natural light), have relatively full spectrum, and also is to have the green light at the same time, close to natural light, when you know a lot of treatment of myopia are to see green things, because it is depends on the green light to repair damage to the eyes, at least not add to myopia.
