Quality Control of Light Emitting Diodes: Using power factor, harmonic distortion and light to power ratios
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
This study addresses quality control for Light Emitting Diodes (LED) according to fouraspects, the power factor of LED lamps, their harmonics and total harmonic distortion (THD), the luminosity for total power to radiated power ratio. It focuses on four brands and six different LED lamps, and concludes that IKEA's LED lamps pertain as the quality lamp, with a power factor over 0.9, THD less than 4% and a power to radiated light of over 4%.
