How much does LED lighting save more than regular lighting?
If the design is reasonable, the luminaire of the same brightness, using LED as a light emitting element, can at least be more energy than incandescent 60%~70%
I see the circuit design of high voltage LED driver for some people, he is not with the step-down switching regulator, but with the series resistance buck, such a scheme can not take advantage of the LED is LED to save power and waste on resistance in series,
. If it is energy-saving effect of lamps and lanterns, the key is to see whether the design is reasonable.
As far as the luminous efficiency of monomer is concerned, LED is ten times higher than incandescent.
