Experimental Determination of Planck’s Constant

is the magnitude of the discrete step in applied voltage over the LED. The experimental determination of Planck’s constant is then easily ob-tained by determining the wavelength of the emitted radiation from an LED and applied voltage over the LED concurrently, solving Eq. (3) for hto yield: h= e V c (4) and substituting the empirical values.

Installation Manual - MEAN WELL

The LED power supply is a dedicated LED driving device that delivers a constant current/voltage or generates an adjustable current controlled by an external dimmer to LEDs. Depending on its types or design concept, some of them not only have PFC capability but also can be located in a harsh environment such as dusty, humid places.
