e difference of 3V. This number divided by the first LED series number (10), are 0.3V, divided by 4mV, can be 75 degrees. Assume that the environment before starting the temperature is 20 degrees, this time the junction temperature should be 95 degrees. Results obtained using this method temperature, certainly better than the heat sink temperature measurement using thermocouples again derive the junction temperature must be accurate lot. To infer from the life of the junction temperature should
