Q:Desk lamp with led bulbs or incandescent lamps good
LED lights: high light efficiency (energy saving), dc drive, no stroboscopic, blue light composition, rich color temperature, color rendering index relative incandescent bulbs will be lower
Q:The LED lamp is bad for your eyesight?
I don't know how you this table lamp LED performance, but the average white LED light slants cold, as compared to that of the object under the LE in natural light color nature is soft, so as a desk lamp may not good for your eyesight. But replace other USES energy-saving lamp is very good at home
Q:Home to buy led desk lamp is broken? Can someone fix it?
First, let people to understand together what is LED lamp, LED lamp is with leds (Light Emitting Diode), namely, the desk lamp of light emitting Diode as light source, LED is a solid-state semiconductor devices, it can be directly put DianZhuan into light. LED lamps mainly on my desk, there should be seen! The led lamp is broken? First, what kind of degree, do you want to look bad if only desk lamp light bead is broken, not bright, it is resistance there is a problem, this will need to change the lamp bead and resistance. As for what's in it? This will still get the special repair shop to repair. If if is changing lamp bead, at the time it was bought on the manual of desk lamp, lamp bead size and style are consistent, avoid safety accident. Led lamp is broken, there are one thousand emergency, they cannot rule out, but they can use opportunely coup to solve one by one. Led desk lamp is broken what can I do the second case is all of the lights, less bright than before, that means that may be a desk lamp internal battery is broken, need to replace a battery at the same time also check link and the power of the thread is broken, if it is a wire is broken, change it, this is unable to repair, no equipment, and can't find the repair method, the solution only replacement. Under the condition of led desk lamp is broken what can I do, actually is a small matter.
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:Plug-in socket 12 led small desk lamp What is its battery model, the input and output voltage of each?
4.5 V to 6 V dc power supply, 12 leds is divided into three groups, each group of four, in parallel, each group of string a 60 euro / 1 w resistor. Can't see the battery is to say, inside the battery is filled of sulfuric acid, general 6 v or 12 v battery will be marked above well. General is 220 v
Q:The LED current problem? LED lamp current problem?
Influence of LED desk lamp constant current job type electric lighting built-in dedicated drive circuit work safety circuit voltage meet (5 v) work pipe external power transmission flow LED light transmission flow always 190 ma or outside the lamp burned if can match current some power supply (5 v) against things can work more
Q:I am doing an LED desk lamp,
LED lamp with a constant current source control, add a photoresistor adjust current source circuit; PWM control, it is not necessary to make it too complicated, say little and a few watts
Q:The lamp that shield an eye is after the light lamp or led the good
LED you to choose natural white warm white (neutral) is not dazzling
Q:How many watts of led the desk lamp that shield an eye with good students
LED the lamp that shield an eye is generally low wattage, not too high, many big brands of LED desk lamp dimming function, need not too care about so wattage. And wattage and is good for your eyes there is no direct relationship, just a matter of personal habits.
Q:LED rechargeable lamp, what to do with the battery can't charge.
The LED rechargeable lamps When first use, adequate electricity, first when not in use, store must supplement electricity once in three months. When using battery lighting lighting obvious dim light need charge in time, otherwise it will affect the battery life. And new LED rechargeable lamps have been used while charging into consideration. New product YG - 3939 jager, YG - 3940, and so on lamp has been achieved using while charging.
