or ordinary silicon diode, the temperature coefficient is about -2mV/oC. However, most LED is not made of silicon materials, it should also go to the temperature coefficient of determination. Fortunately, various LED manufacturers data sheet gives most of its temperature coefficient. For example, Crees XLamp7090XR-E high-power LED, the temperature coefficient of -4mV/oC. Than ordinary silicon diode 2 times larger. In the United States Puri array LED (BXRA) to give a more detailed data.
