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:The voltage of the LED lamp is about how much
If you buy a product of lamps and lanterns, it should indicate the rated voltage. If it is homemade, you can choose according to the input voltage connection. You three series, 5 groups and then together, you can pick up in 10 v
Q:Led lamp, good point light source or surface light source
Led has blue light damage, not only with long time eye fatigue This is my least favorite Use dc after light lamp, now is very good Basic do not have the feeling of fatigue
Q:LED lamp is broken, put it down, things do
The LED lights down, connected to two wires, is is, negative negative, on two batteries.
Q:How many watts of LED3 is equal to the ordinary energy-saving lamps
Led3 tile, led3 tile how bright, 11 w energy-saving lamp is equivalent to, energy-saving lamp wattage, how many watts of energy saving lamps, energy-saving lamps how many watts, 3 w energy-saving lamps, energy-saving lamps, how many tile home how many tile energy-saving lamps, 13 w energy-saving lamps,
Q:Amount for the LED - 666 desk lamp can use charging time
Strictly speaking, it is best not to use when charging. Because: 1. Easy to get an electric shock. 1. Affect the service life of the product.
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:Baby what kind of table lamp? The LED lamp can be eye really?
Can protect your eyes, the light is primarily a stroboscopic damage to eyes, buy a desk lamp should pay attention to several problems: < ol > < li > stroboscopic, using a mobile phone or camera shot from close range luminous part, really no stroboscopic is made less than one line in the flashing < / li > < li > brightness and glare: never do desk lamp brightness is too high, about 6 to 9 w can meet the requirements of brightness, see glowing part directly, without strong dazzling, dazzling degree as small as possible < / li 
Q:General led desk lamp how much a led lamp is usually how many watts
Generally a combination of desk lamp and lighting conditions can choose 3 w - 5 wled ball bubble lamp, high again feel too dazzling,
Q:How long will leds last?
Comparing to conventional light bulb is very durable. LED in general notes, can be used more than 50000 hours, and some producers to promote their LED can operate 100000 hours. The main problem is that the LED is not a simple operation, no longer its rated life cannot use traditional lamps and lanterns of measure method to calculate. In fact, when testing the LED life, no one will stay beside waiting for it to stop working. However, there are still other ways to calculate the service life of the LED. LED is lasting, because it won't produce filament fuse problem. Leds will not stop working directly, but it will gradually degraded over time. Forecasts suggest that high quality LED after 50000 hours of continuous operation, also can maintain more than 60% of the initial degree of the light. Assumes that the LED has reached its rated service life, in fact, it may still be shine, just the light is very weak. Want to prolong the service life of the LED, it is necessary to reduce or completely dispel the heat energy produced is the LED chip. Heat energy is a major cause of leds stopped working, LED the life of the related to LED chip and ELDerly drivers.
