Q:LED the desk lamp that shield an eye to choose good warm light or white light is good?

Should choose the warm light, soft and not dazzling.Which is better than the sun warm light

Q:The LED lamp male female connector can be removed?

When possible, link need to pay attention to the several: 1, LED driver need to distinguish between is negative, you to pay more attention to the joint of the line is negative, don't answer the reverse;

Q:How to identify what the real eye lamp?

And people accidentally touch can also cause accidental burns, it is for people with a safe hidden trouble problems. While the LED lamp will not produce this kind of situation, Angle lights lamps are doing reliability test of time, five desk lamp work for two weeks in a row, the lamp body, the highest temperature is no more than 40 degrees, most Gao Wudu than the environment temperature, from this point of view, the LED desk lamp more security than the general desk lamp. x0d third, LED desk lamp spectrum is the most close to the sun, and every day we at least half of the time exposed to sunlight, the human eye to adapt to the sun is the most, so add a light source can be infinite close to the sun, so our eyes under the influence of light will be more less, the human eye would feel more comfortable. So as to achieve the purpose of the eye!

Q:How many good study led desk lamp

LED lamp general 6/7 w is very bright, too light is bad for your eyes, Color temperature 4000-4000 about the most appropriate.

Q:Folding LED touch lamp generally will be problematic

This topic is not answer, because the LED control method are many, and the way of touch also many, control way is very much also, only from the basic principles. Caused by electric current is the main reason for the failure of light, at the same time, the LED lamps and lanterns has typical characteristics of diode (very small voltage variation, huge current change) so, LED lights control method based on current control is the best, since it is control cannot use constant current source, but to use can control constant current source. In controllable constant current source, a switch type and linear type, because the switch type is inductance as the main device, and a sharp tuning switch frequency will cause many problems, it is easy to damage the leds, controllable linear constant current source is low efficiency, but the problem is less easy to implement.

Q:Led rechargeable lamp, charging is completed, charging indicator light color?

It depends on your desk lamp charging circuit design. If the overcharge protection circuit, the circuit design charging is completed will change color. If charging circuit is pure, not overcharge protection, will not change color. Of course, there are overcharge protection circuit is better than not overcharge protection circuit

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.

Energy-saving lamps, color rendering index above 80, it has a variety of color temperature. Read a book, I suggest to use 4000 k; High color temperature advantageous to concentrate, but Dazzling; Low colour temperature of concentrate. When reading a book, lamp writes a 1.5 meters, 300-350 lux. So-called energy-saving lamps, is high frequency, otherwise, it is not energy-saving lamps.

Q:I want to buy a charging desk lamp, LED lamp brightness seems a bit low, if it is a 13 w the lamp that shield an eye brightness LED small bulb, how many is needed to achieve the same brightness?? Have LED to the eyes good yao I to a charge of desk lamp, thank you

The best or dc lamp Now are using the compound light lamp There is a patent for invention

Q:Buy the LED desk lamp, what should be pay attention to

But the LED lamp bead quality difference is very big, inferior lamp bead to the eyes not only useless, still can damage the eyes. Due to the LED manufacturing process of the core technology or in the hands of big foreign companies, so try to choose imported LED lamp bead, using the lamp that shield an eye is the guarantee of quality of the light source is the most important. The other is the appearance, price and other external factors

Q:What if the led lamp doesn't shine

If it is a line break have to pick up, if there is black spots is the LED surface that is was burnt out, that is about to change the LED. Many of the LED circuit adopts the series circuit, that is to say an LED bad throughout the series circuit will not bright. Generally LED not easy bad, usually a transformer is the most easy to bad. Open it and see it
