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 rechargeable lamp, battery voltage is how many v?
Using is a kind of super high brightness LED flashlight, its working voltage is higher, generally 3.35 V - 3.65 V, working current is relatively large, at 30 ma -- -- -- -- -- 50 ma, high brightness. Above is reproduced, the following is what I write. You can also in the baidu search is known here. 1, rechargeable lamps with light emitting diode and a flashlight with should be the same. The above work should be refers to the voltage on single diode voltage. Don't know how much is the battery pressure is how even get to see that a few diode. But according to my experience, I've hurt countless this flashlight and desk lamp) 4 v battery voltage is not the batteries are lead sulfate is 6 v battery. 2, see the internal structure of light emitting diode, the bulk of the pole is negative, the light of the part is connected to the cathode, or look at like a bowl of concave portion of the attached to the cathode. 3, heard "filament" if you want to ask is "filament light source" refers to a hot filament of the bulb, tube produced by light sources; If you want to ask is "filament voltage" is refers to the added on both ends of the filament voltage. Case there is a small light bulb and a dry cell formed a closed circuit is: at the ends of the battery voltage = bulb voltage + the consumption of battery internal resistance. Usually learn high school electricity can use this relationship. 4, x ray tube, extreme conditions, the theory of complex sentence couldn't say for sure.
Q:The LED lamp can change the light bulb
Can, but want to use soldering iron, more troublesome, generally in all the places selling electronic components.
Q:LED the desk lamp that shield an eye to choose good warm light or white light is good?
All said no white or warm white light, how still stubbornly say which good? So you say like fluorescent lamp of white or yellow incandescent lamp? Want to that is that, it's all the same eyes, no better.
Q:Plug-in socket 12 led small desk lamp What is its battery model, the input and output voltage of each?
4.5 V to 6 V dc power supply, 12 leds is divided into three groups, each group of four, in parallel, each group of string a 60 euro / 1 w resistor
Q:The LED rechargeable lamps can charge while lighting? The reason?
Desk lamp is not poor, not because of burn out, because the light and a battery, so the voltage may be no more than the battery voltage
Q:The led lamp charging more than 24 hours have what dangerous?????
Authentic qualified desk lamp, the battery charging protection circuit for battery will not overcharge, adequate electricity stopped. He was afraid the streets or other simple knockoffs, charge for a long time is important for battery life.
Q:Long card LED charging small desk lamp
According to the instruction of filling. Led lights is very save electricity. 1000 w (tile) with electric drive for an hour once electricity, such as lamp 10 w, 100 hours once electricity, a kw lamp wattage that number is how many hours once the power point
Q:LED bulbs, use in the home, have harm to the eyes?
No harm. But there is no need long time staring at it
Q::Rechargeable led bulbs on the desk lamp is a few volts?
General single LED lamp bead voltage range is 3.0-3.5 V. Your lamps of lead-acid battery rated voltage is how many? (you can have a look at a few hole, every hole is 2 v, if it is 3 hole, so the voltage should be 6 v.
