Efficiency relationship of LED parameters in solid state lighting

Abstract

In this study the power, power factor, correlated color temperature (CCT), color rendering index (CRI), lux values measured from 0.75 m distance, LED lamp temperatures and changes in the currents of 6 LED lamps, which are most commonly used and directly connected to the network are experientially recorded. The effects seen from the very start and 1 hour later, on LED lamps were compared in terms of temperature, current, and lux values. The high temperature values on the LED were seen to have adverse effects on the efficiency of the LED lamp
