V look to a junction temperature can be drawn. In fact, LED mostly in series and then parallel to many, that does not matter, when the voltage difference between the LED in series by many of the common contribution, so should the voltage difference divided by the LED in series divided by the number of go 4mV, you can get the junction temperature. For example, LED strings 2 and 10, the first measured voltage is 33V, the second time after the heat balance of the measured voltage is 30V, the voltag
