The LED current problem? LED lamp current problem? Said wanted to plan to buy USB LED lamp to use 5 v voltage current 190 ma computer USB interface as current 500 adapter up to 1 a pick 1 a current
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
Power supply voltage will not have an impact on power electronics, electrical appliances it needed current from power supply only, will not change because of the size of the power supply current.
USB interface receive computer desk lamp, computer burden is heavy, easy to addled computer. Besides, desk lamp, desk lamp, 1 a current lamp current 190 ma, bad, or move a few desk lamp table lamp lights die.
