[IEEE 2018 VII. Lighting Conference of the Visegrad Countries (Lumen V4) - Trebic, Czech Republic (2018.9.18-2018.9.20)] 2018 VII. Lighting Conference of the Visegrad Countries (Lumen V4) - Future Photometry Based on Solid-State Lighting Products - Joint Research Project of European Metrology Institutes
摘要： Luminous flux (lm) and active electrical power consumption (W) of new SSL products coming to market are measured at test laboratories in order to determine the luminous efficacy (lm/W) and energy class of the products. Due to the fact that spectral responsivities of V(λ)-filtered photometers differ from the defined CIE V(λ) curve, all photometers are typically calibrated using light with correlated colour temperature (CCT) of 2856 K. This causes unwanted spectral errors in the measurements of SSL products at test laboratories and also in the field due to the large differences in the spectra of calibration sources and the light being measured, and in many cases cannot be corrected for. The EMPIR (European Metrology Programme for Innovation and Research) project 15SIB07 PhotoLED addresses the obsolescence of traditional incandescent standard lamp technology used in photometry and the need to support the introduction and uptake of solid-state lighting (SSL) products. It develops and validates the basis for a new photometric system based on white LEDs, by developing new LED-based calibration sources and measurement techniques supporting the specific properties of the new light sources and detector technology including illuminance measurement of the new LED-sources without optical V(λ)-filters in the calibration of photometers and measurement facilities used for determining the energy efficiency of new SSL products coming to market.

[IEEE 2018 4th International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT) - Mangalore, India (2018.9.6-2018.9.8)] 2018 4th International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT) - A concept of energy efficient LED lighting using Power-over-Ethernet (PoE) technology
摘要： LED lighting is found universal acceptance for being affordable and energy ef?cient. The next big step for LED lighting is enabling LED ?xtures to work in Internet-of- Things (IoT) infrastructure. Power-over-Ethernet(PoE) standard delivers power and data via a Ethernet cable from a power source such as a hub directly to the network port of a connected powered device, in the case of lighting the powered device can be a LED bulb.In this paper the concept of energy ef?cient LED lighting using PoE technology is discussed in brief.The bene?ts PoE technology provides and challenges that needs to be addressed are highlighted.
