Q:With few desk lamp LED tile good children

Between 5 w - 8 w, no stroboscopic, can choose move light and color temperature of LED desk lamp

Q:Are LED lights compared to dc lights?

Basically agree with net friend in front of the answer. The desk lamp of ordinary incandescent light bulbs with energy-saving lamps, bulbs and tubes in the current is an alternating current. Incandescent lamp current is ac mains, 50 hz, on and off the 100 times per second. Filament is high temperature heating, heat capacity to a certain extent, to cool and hot, stroboscopic was not obvious, but low light efficiency, energy saving. Energy-saving lamps, is the mains ac rectifier dc, again for the high frequency inverter (several thousand Hz) communication, energy saving, stroboscopic is not obvious, not like a normal fluorescent lamp. LED desk lamp, the energy conservation, but see, on the market at present basically is a built-in battery, use mains charging can't use the lamp, can light up from the mains before, often charging more than 6 hours, often should charge, so if used in a short time is can, such as to use for light continuously over a long period of time, is not convenient. LED flashlight, with short time, it is very good. If there is no battery, do not need to charge, it is more convenient. Above for your reference.

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:A LED light source is, but is not a plug-in, the power supply is a similar phone charger that this kind of desk lamp belongs to direct current (dc) or an alternating current, will it be a stroboscopic?

Normal LED desk lamp not stroboscopic, this is decided by are rechargeable LED desk lamp power supply. 1, the common battery power, the power supply itself is no stroboscopic characteristics, driven by its leds stroboscopic may not happen. 2, use UBS power, UBS power is through the conversion of switch power supply dc voltage source, the voltage fluctuation is small, could not have caused the LED strobe. 3, using a dedicated dc power supply, its form has two kinds of current source and voltage source, are generally not switching power supply, stability is very good also, normally not stroboscopic. If it is found that the LED light stroboscopic explained the power supply circuit and fault, such as open circuit, LED lamp trouble light filtering capacitance.

Q:Desk lamp with led bulbs or incandescent lamps good

Comprehensive the above information, combined with their own situation, you will know how to choose, the hope can help you!

Q:LED lamp base fever is normal

Soon open lamp base is a bit hot, it is possible, because the LED need to drive to work, drive a similar electronic transformer, provide the LED constant current work, if the drive power design are critical, the switch of the transformer, power tube heat dissipation is not good, and relatively large current, will be hot

Q:Led rechargeable lamps how to charge

Lead-acid battery charging requirement after filled with a floating time state, with the changed the user capacity and circuit design is difficult to grasp, because charging time short, filling is too long to form a rechargeable battery life shortened, theonly low-grade products without charging protection circuit, only carefully study the product description. A rough judgment

Q:Philips crystal sharp LED the desk lamp that shield an eye light bulb is broken?

Can only be built, and the lamp place also is not necessarily good, the first thing to chip, color temperature is the same

Q:I buy LED lamp light moving light and shade is how to return a responsibility

Use this kind of desk lamp and your intention, originally is for energy saving eye, in the end it may hurt your eyes, it is recommended that you immediately change other brand of high quality the desk lamp that shield an eye, when choosing comparison and observation, the most basic points, 1, there cannot be any flicker; 2, light color must be pure white; 3, the mi live eyes LED luminous tube array, all brightness light-emitting tube must be consistent; 4 hand touch LED parts, can not have obvious temperature rise. Otherwise it is inferior product.

Q:Heard that LED energy saving effect is very good, but in the family use, very dazzling LED? Harm to the eyes? Can not find a standard answer online, please help!

The LED light intensity is higher. Will be dazzling. Don't staring at the lamp directly, it just like the sun, did you say the sun to eye damage, used to make lamps and lanterns is good, but the light intensity is less, not hitting the eyes directly. Color rendering index higher than traditional lamp, used for lighting lamps and lanterns is good, good. But also energy saving. Life is long. According to the eye, it is harmful. By the way, would suggest that sell grinding gauze shade of that.
