Q:Hello, I would like to ask you, if the desk lamp of household how much leds W?
In general, the bright LED lights, the brightness of the 1 watt equivalent to 20 watts incandescent lamp, therefore, used as a table lamp at close range, 3 watt LED lamp brightness should be sufficient. About the color temperature, personally think that as long as you feel comfortable, but the color temperature is too high may feel dazzling, easily tired... Might as well choose between 3500 ~ 6000 ° K.
Q:How to maintenance of led desk lamp filled in no electricity
It seems is the switching power supply, circuit board above and have a look. You understand the welding and the multimeter test? If you don't send repair shop
Q:Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?
The output ac socket After the transformer voltage between 8 v 10 v 20 v ranging from energy-saving led equivalent
Q:What is the battery charging led lamps use
Led desk lamp is very save electricity, 1000 mah battery to charge you can use for a long time. Because each led lamp bead take 5 mm encapsulation of about 0.06 w. and I think you should buy is 1000 mah, not may have such a large capacity. We use the cell phone battery is probably about 1000 mah, you can't lamp inside a large batteries. For battery charging and charging the mobile phone, light to dark will have to charge, per charge charge about 3-5 hours is enough. And he said 250 times is not accurate. Normal use, you should see the lamp used in the quality of the battery, and a quality LED lamp itself.
Q:Led desk lamp and common desk lamp which is good
If the wavelength change, stimulate phosphor ability to drop, luminous efficiency will be lower. Manufacturers in order to pursue the brightness, usually to strengthen the blue LED light intensity, the eye if the long run, such a source to avoid eyes blue light damage. In addition, it is, the longer the LED light, the faster the phosphor decay of light source, the result will lead to the human eye contact blue wavelengths of light is more and more intense, so as to cause harm to the human eye
Q:The LED fluorescent lamp color temperature probably how many is the best
This is hard to generalize. Because of individual differences, habits and customs is different, also different for lighting light color temperature preferences. In general, white people prefer warm color light (2700 ~ 4000 k), the reason is that this kind of lighting light of skin appear ruddy health; Most of the yellow race like daylight color white light (5500 k) or slightly cold blue pigments, the reason is that the light appears bright.
Q:Are LED lights constantly flashing
Ha ha There are two kinds of LED lights also, communicate in dc and use. But common desk lamp, mostly in the form of dc. You understand dc, ac rectifier, the pulsating dc lamp USES is not such, pulsating dc also need through the filter, is smooth waveform, voltage (or current) waveform into a straight line. So, this desk lamp is not flash. But suggest reading use desk lamp, the best or incandescent lamp, its spectrum make the eye is the most comfortable, reading books is not easy to fatigue, thermal inertia of the filament lights are very stable (not flashing), using fluorescent lamp, energy-saving lamp, the lamp that shield an eye, etc.) can also be, comfort. LED lamp current spectrum is a single, intuitive is very dazzling, used to read easily fatigue, comfort is the worst.
Q:I want to ask to buy what kind of bulb to eyes good, leds? How many watts
I suggest you study, do not use ordinary LED lights. Because ordinary LED lights are blue and yellow light, blue light adverse to the people, and its color rendering index and low. Hello you say this kind of situation as to how many watts of specific room to install light to protect eyesight. There is no clear regulation on medicine. Guidance: But to light and shade is appropriate, not too bright nor too dark for the best. If the children often learn can buy the lamp that shield an eye The average 30 watts around the small room can use energy-saving lamps, desk lamp can be used at the same time 12 watts around the lamp that shield an eye is better. Use energy-efficient light bulbs as a lamp bulb, 7 watts is appropriate, eyes feel comfortable, but you can buy a small guard no radiation the lamp that shield an eye, the lamp no ordinary electromagnetic radiation hazard, the lamp that shield an eye dry eye not to now, the light is not dazzling light design. In general, the bright LED lights, the brightness of the 1 watt equivalent to 20 watts incandescent lamp, therefore, used as a table lamp at close range, 3 watt LED lamp brightness should be sufficient. About the color temperature, personally think that as long as you feel comfortable, but the color temperature is too high may feel dazzling, easily tired... Might as well choose between 3500 ~ 6000 ° K. 3 w, 7 w will be stabbed eyes, desk lamp advice or use energy-saving light downier, in general, color temperature of 2700-3100 is suitable, is the warm light and natural light, white light 6400 of real life, we still use more but look for a long time, eyes will sting. There is no best, only the ideal of the lamp that shield an eye is the best color rendering of incandescent lamp, 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. Choose Bai Zhi lamp wattage nearly 25 appropriate up to standard? ! white
Q:LED lamp, lens type and light type which good,
Besides, desk lamp, desk lamp is the design standard of infinite close to the sun, because artificial forever than nature. So now the LED lamp like stressed without glare No stroboscopic, no radiation it is for this reason, who is more close to the sun, who is better. Lens is concentrated, shoot the lamp to use more widely. But the lamp's goal is to the sun, condenser is used to make fire, not reading, so the desk lamp of type lens to eliminate. But why want to do the desk lamp of type lens? To be sure, lens type basic it is inferior goods, a treasure to 28 yuan still pack mail. Because it is very low, LED brightness is not enough, so I had to use a lens to concentrated, more brighter. Here again there is a drawback, because leds are more than one, generally has more than 20 a desk lamp. Every one have a focusing lens, the end result is to write ghosting, seriously affect vision. So, choose planar light is better, the use of the sun in the standard.
Q:LED lamp circuit of current more conference appear what problem
LED current assembly LED life expectancy, calorific value is big, long droop decay quickly makes the current big but light from the darkness, also is actually short service life. String or depending on the design of the circuit. The string of reasonable and important. LED type belongs to the current control device, it is recommended that the concatenated as much as possible, control current. But the list of much needed voltage too much is bad for safety. When the number of string reaches the corresponding voltage should be increased and accordingly. Such as lamp had better control transformer within the safety voltage is better, after 24 v, for example, the pressure drop of about 3 v LED, and the best in a 6-7 more appropriate, the branch with current constant flow control device for the LED work, the more number of lights, and the same number again with constant current control, this is more reasonable.
