“…As an LED is powered, power dissipated P LED at the junction increases its temperature, as a result LED forward voltage V F decreases, causing the LED to draw more current as junction temperature increases. This situation is illustrated in Figure 5a, if the current is not limited, junction temperature increases drawing more current, which heats it up more, causing increased current, potentially leading to a situation known as Thermal runaway, a condition leading to the destruction of the LED (Arnold, 2004;Fan et al, 2011;Liu & Fang, 2012;Lu et al, 2009;Meneghesso et al, 2002;Pecht & Chang, 2013).…”
