LEDs created by Seoul Semiconductor can work on AC electric power without having a DC converter. For each half-cycle, Element of the LED emits light and portion is dark, and this is reversed over the next 50 percent-cycle. The efficiency of this kind of HP-LED is often forty lm/W.[134] A large number of LED things in series may be able to operate straight from line voltage.
Blue LEDs have an Lively area consisting of a number of InGaN quantum wells sandwiched involving thicker layers of GaN, known as cladding layers. By varying the relative In/Ga fraction within the InGaN quantum wells, the light emission can in principle be diverse from violet to amber.
