- Q:The led lamp charging more than 24 hours have what dangerous?????
- Nothing dangerous, now of the rechargeable battery charging circuit with protection circuit, with or after high temperature will automatically stop charging
- Q:Want to buy the university dormitory with plug-in study desk lamp, LED the good good or tubes
- Some leds, white light is light, but some dazzling, often stay up late to some, more useful. The yellow is better for your eyes
- Q:General how long LED desk lamp charging full of learning
- Depends on the size of the battery capacity, average about 1000 ma, 4 to 6 hours is full.
- Q:Mid-december, folded - 924 led charging desk lamp, the eyes?
- To see from the Angle of optical: traditional light source, including the red wavelengths of light, you can understand as invisible infrared, the over 780 - nm wavelength radiation can cause damage to the eyes, myopia are mostly indoors for a long time, too much rely on under the traditional lighting light caused by the work and study. And LED light source, mainly is the blue chip inspire yellow phosphor, the wavelength of light in between 380-780 nm, no ultraviolet and infrared light, good LED light source (note is good, usually see in stores outside does not conform to the mostly, the current domestic exports have all the good) color rendering index greater than 85 (color rendering index, the higher the more close to natural light), have relatively full spectrum, and also is to have the green light at the same time, close to natural light, a lot of time to treat myopia are to see green things, because it is depends on the green light to repair damage to the eyes, at least not add to myopia.
- Q:LED lamp circuit of current more conference appear what problem
- Will first fever, if it is too big, can burn out directly. On the issue of the lights, string, and, have a plenty of string and share
- Q:How many good study led desk lamp
- Last year I bought her son a 7-day's, now take down the feeling is very good
- Q:So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
- Line loss, it is good to connect.Of course, can also according to component model and buy a change.
- Q:The led bulb loaded on the adjustable light lamp is broken
- LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
- Q:How to repair the led rechargeable small desk lamp
- The cause of the damage may have three, the first wire solder joints from or switch contact bad, you carefully check each except; The second is lead-acid battery damage can't charge; The third line fault is charging, the charger for capacitance, rectifier diode, resistor, the most easily broken is the capacitance, then inspect diode. If you didn't have electrical knowledge, please do not repair, in order to avoid dangerous.
- Q:Three lights in parallel, and should be how the resistance of the step-down series?
- 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.
