Q:Led lithium battery lamp, rated input current 0.5 a
Here need to popularize A common sense, when you LED lamp or cell phone, the above label for 5 v 0.5 A charging parameters, the charger you even 5 v 100 A, you put the LED lights or cell phone plugged into the charger in, is safe and reliable, not because the charger is 100 A, think at this point is to use 100 A for your LED lights, mobile phone recharge, 100 A here refers to the charger output capacity can reach 100 A, it can at the same time for the 200 only 5 v 0.5 A LED lamp, charging the mobile phone. 220 v voltage is like family, when your family power supply power supply capacity of 10 A, he can light up 100 22 w bulb at the same time (220 v * 0.1 A = 22 w), A light bulb is 220 v 0.1 A, even if you only opened up A light bulb in the home, the light bulb will not burn because of the power supply capacity of 10 A. When A family with only one bulb light, at this time is 0.1 A current through the bulb, rather than 10 A.
Q:Desk lamp good still tube of good to buy LED strips?
A low power consumption and lower power LED that LED the working voltage of is generally 2-3.6 V. The working current of 0.02-0.03 - A. That is to say: it consumes the electricity is not more than 0.1 W. 5, green environmental protection, high efficiency and energy saving, the LED is made from non-toxic material, unlike fluorescent mercury can cause pollution, at the same time, the LED can also be reused.
Q:LED lamp, lens type and light type which good,
Because of the high LED lamp brightness, focus, look into the LED lamp bead will be very dazzling. If you don't look straight into the LED lights, people's eyes, it is recommended to use a lens type, using planar light conversely.
Q:Home to buy led desk lamp is broken? Can someone fix it?
There are also a lot of emergency, at present is that several kinds of the most common, actually what led desk lamp is broken, this also need careful maintenance and care for at ordinary times, avoid to touch water, avoid excessive lamp switch frequently, it will affect the use of lamps and lanterns, anyhow how bad how to solve, most people do in led desk lamp is broken, is discarded, to buy one, this way is not no, since the advocating environmental protection, can repair to reoccupy is also a very good treatment.
Q:LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
Who recommended the first floor of the answer, he was mistaken about the basic knowledge, also recommended? Three kinds of lamp, incandescent lamp the best color, color rendering index of 99 above, by contrast, it is best for your eyes, but the color temperature is too low, only 2850 k, easy to disperse. Again, it can charge.
Q:LED lamp general 6/7 w is very bright, is too light is bad for your eyes
Charging circuit disconnection or the charger itself has a problem
Q:How many watts of led the desk lamp that shield an eye with good students
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.
Q:So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
Whether the welding is wrong or high temperature component breakdown welding time is too long to make? So you can skip the touch element directly using the switch on and off, of course, can also according to component model and buy a change.
Q:Do LED lamps really protect your eyes?
LED desk lamp is a direct current (dc), with common desk lamp of comparative advantage is no stroboscopic and dazzle light, so is good for your eyes!
Q:LED bulbs, use in the home, have harm to the eyes?
I'm a little confused You this does not display the word Do only light That you don't need to control card
