We compare the device performance of a conventional light emitting diode (LED) module with that of an LED module after electroplating a lateral heat dissipation (LHD) structure along the sidewalls of the chip. At 350 mA, the luminous intensity of the proposed LED was enhanced by 207%. At the same current, the dominant and peak wavelength shifts of the LED exhibited a better performance of 2.1 and 4.4 nm, respectively, compared with the conventional performance of 7.2 and 23 nm. These results indicate that the LED with the LHD structure is useful in improving the performance by enabling greater heat dissipation. (C) 2010 The Electrochemical Society.
