Abstract: A method for fabricating a high voltage light emitting diode (HV LED) includes: calculating a total area of the HV LED according to a predetermined light emission luminance; calculating the number of sub-LEDs according to a predetermined operating voltage; subtracting, from the total area, areas of isolation trenches between the sub-LEDs, electrode areas and areas of series-connected conductive leads between the sub-LEDs, and then dividing the difference obtained through the subtraction by the number of the sub-LEDs, so as to calculate an effective light emission area of each of the sub-LEDs; and according to the effective light emission area, adjusting the area of a sub-LED having an electrode and the area of a sub-LED having no electrode, so as to enable the area of the sub-LED having an electrode to be greater than the area of the sub-LED having no electrode. An HV LED manufactured by the above method.
