How to systematically identify the heat dissipation of LED track lighting lamps?
“Half hour illuminance method” to measure junction temperature.
Since we can’t measure the LED COB track lighting junction temperature directly, is there an indirect way to know it junction temperature? Fortunately, when the COB LED junction temperature rises, the track light luminous flux will decrease. Then, as long as we measure the illuminance change of the lamp at the same position, we can reverse the change of junction temperature.
