The LED rechargeable lamps can charge while lighting? The reason?
Don't use as much as possible. Not LED burned, but may cause electrical shock. The lamp with capacitive reactance of capacitor step-down charging, lead battery energy storage. Once leakage, will be the 220 v mains by conduction electrolyte to turn on the light in the hand, have life risk. Burn out leds are still in the second.
resistance capacity is determined the capacity of capacitance current, and the charging current is very small, generally in 1 u for many, the charging current is about 70 ma, 13, and light bead is usually a 20 ma, that is the lamp bead is 260 ma, so four hours to point to a hour, if charge while using, then charge electric light enough to use, the end result is the battery voltage drops to light bead, is about 3.2 V, that is to say the battery will discharge, after filling is filling in a difficult, because with lead-acid batteries.
Desk lamp is not poor, not because of burn out, because the light and a battery, so the voltage may be no more than the battery voltage
Can't, or it will burn out all on your desk lamp led diode, the reason is that the charger is not isolation transformer, but electronic charger, electronic charger with high pressure when charging, if turn on the light use, breakdown, all leds, so can't charge while lighting
