Verification Method

The D.U.T is an indoor LED luminaire for suspended mounting. The luminaire is provided with one COB LED equipped with secondary optic (lens) and external control gear. The control gear is capable to provide dimming via DALI interface. For the purpose of the Low Optical Flicker verification program, the following tests were conducted at the specified dimming levels: BLO (base Light Output without dimmer in the circuit), 100% Light Output, 20% Light Output and 10% Light Output. The corresponding waveform at each dimming level was captured via oscilloscope coupled to transimpedence amplifier and integrating sphere system.
