What are led lamp accessories
USB cable, drive power panel. + 3, rechargeable, rechargeable battery, voltage regulator circuit board (rechargeable).
Want to buy the university dormitory with plug-in study desk lamp, LED the good good or tubes
I last year in the university, my major is electronic, originally in my common sense, because LED driver circuit is simple, and high efficiency, think it would be better, but after a year of actual experience, found that for the LED lamp cold light color, and as for the circuit quality than charging inverter type fluorescent lamp (bulb),
With 10 v charger with 6 v rechargeable batteries used at the same time, that is used when mains mains, there is no mains automatic conversion electric battery. Three light bead is in series or parallel good? Add how much resistance? Step-down to to the charger? If I want the dimmer, should how to do, had better have circuit diagram
What is your 6 v battery batteries? Small battery (battery)? 10 v charger to see what the battery charger, if the battery can work with, if nimh electricity or lithium electricity will reduce the voltage. How much is the pressure light bulb? It is best to parallel, serial word broke a are not lit up. Add how much resistance depends on what you use the lamp, or led. The dimming added potentiator current limiting. How to do is very simple, still with the figure? Charger and battery, lamps (and) series of potentiometer. If it is nickel metal hydride batteries can't do, for a long time will seriously affect the battery life in charging status. The more complex.
A led desk lamp always zi zi ring is how to return a responsibility?
Inside thrum have poor contact, look at the best, don't have accidents
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.
Led rechargeable lamp, charging is completed, charging indicator light color?
There are two kinds of lamp battery: Lithium battery charge with mobile phone charge, same instructions filled with red light turns green said, such as no charging indicator can only refer to the instructions. Lead-acid batteries used in dozens of pieces of low-grade called students or children desk lamp, rechargeable light most of the products will not change color, usually from a few hours to ten hours. 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. Rough judgment: try every half hour after 2 hours filling light observation (do not charge while light), and if no longer increases should be full of light is the brightest and desk lamp brightness, floating charge time same again can
I want to buy a charging desk lamp, LED lamp brightness seems a bit low, if it is a 13 w the lamp that shield an eye brightness LED small bulb, how many is needed to achieve the same brightness?? Have LED to the eyes good yao I to a charge of desk lamp, thank you
The best or dc lamp Now are using the compound light lamp There is a patent for invention
The LED lamp can use while charging?
Can, but it is not recommended to do so. Mobile phone can also charge while playing, but also have exploded. While filling in terms of electrical damage!
