Broca-Sulzer Effect Detection over Critical Fusion Frequency for Pulse Operated White LEDs with Varied Pulse Shape

Popis výsledku v původním jazyce

This paper is concerned with the detection of subjective brightness enhancement effect achieved by pulsed operation of light emitting diodes (LEDs). In this paper the LEDs are driven by several kinds of waveforms with fixed duty ratio and frequency. Their subjective brightness is compared against a DC driven LED. The results support the hypothesis that there is an enhancement effect for ideal pulse and it disappears when either the rising or falling slope is non-ideal.
