- Q:Study desk lamp high-power led is more appropriate
- Preferred the desk lamp of dc, because traditional 220 v ac 50 hz residual current fluctuations, causing light stroboscopic phenomenon. Stroboscopic is easy to cause eye fatigue, vision loss, deepen myopia. And preferred light yellow light, the light is warm, warm and comfortable, stable, not dazzling. Another is to see whether there is ultraviolet (uv) radiation.
- Q:LED desk lamp, very bright, when buy later with more and more dark
- May be there is a LED lamp bead the leakage fault happens, the first thought that all leds are connected in parallel, and then string a current limiting resistor, so if there is a leakage, the overall current will increase, lead to partial pressure increases, resistor LED voltage drop, when the LED thoroughly after short circuit, all the LED all the electricity, so there is no light. Although the LED life is very long, but in fact, the life of the LED and no imagination in so long, especially high brightness tube, electrostatic breakdown them easily.
- Q:What is the battery charging led lamps use
- We talk about the LED bulbs for first, namely light-emitting diodes (leds), the working voltage of it around 1 v, current dozens of ma can light it, this is also the characteristics of it can save electricity, because the LED working voltage is very low, if you wait until dark light bulb, it shows that the battery has been severely deficient electric (that's Achilles' heel of the battery). And as the power of its work the most time is also hundreds of ma maintenance-free lead-acid battery, you should say ten dollars, it is this), if is lead-acid batteries, will be added in time, only under the condition of the battery voltage and current saturated plate vulcanizing speed of the slowest, keep up with a three to five years is no problem. If your battery is lithium electricity or nickel, head a few times when the electricity again after filling completely (this is to activate the various chemicals inside), the time is 15 hours (around 500 ma charger) the following 14 hours, in use process (charger during normal use 200-300 ma, charging time of 8 hours) it is best not to let it lose the electricity charge again, li-ion battery and nickel electric prone to memory, long battery capacity will be more and more small, the last rush is full, one with no phenomenon, that is the life of the battery the end of the walk.
- Q:Small leds, charging when hear the sound of the PI PI is what circumstance?
- I hope you can help me.Still had better not use, and a little insecure
- Q:How bright flowers LED desk lamp, good quality
- Generally see lights with LED has obvious advantages, to buy the children learning advice to wait to buy the LED lamps and lanterns, to miss the rush stages will be better. In fact, all sorts of lamps and lanterns are the national standard, as long as accord with a standard can be used.
- Q:The child for LED the desk lamp that shield an eye myopia?
- Leds do not suit for children do their homework, last year I bought a LED desk lamp to the child, want to look at the instruction research just bought back, see the directions even write is not recommended for children under the age of 14, but the outer packing are written on the desk lamp that shield an eye, anyway, I understand the desk lamp that shield an eye is certainly protect eyes, later can't, have to to give children bought a desk lamp.
- 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:How many volts 4 w power led desk lamp
- Because the chandelier will usually multiple LED ball steep light, the combined ten several watts, home has now is very bright. Use LED panel lights, with the scale of the 300 * 300 mm, is about 10 w. Family condole with LED lights, can use 3528 lamp tape. Wine cabinet or closet to choose LED tube light, can use the 1 w or 3 w. Hope help.
- Q:Why is the largest lamp radiation?
- The expert reminds: currently on the market is filled with all kinds of cheap inferior LED desk lamp. Is common medical test and optical test showed that the LED blue light damage, only through the blu-ray isolated from the desk lamp of the blue is the blue light lamp. When parents choose and buy the lamp don't blindly covet a low price.
- Q:Led desk lamp and common desk lamp which is good
- The launch of the white light LED light source can form mainly consisted of 450 ~ 455 nm wavelength of the blue light stimulate phosphor powder, including lower wavelength firing ability are more strong. Usually LED lights factory within a 500 - nm wavelength control, generally is 450 ~ 455 nm or 455 ~ 460 nm, belong to the strongest radiation damage extents
