Mobile light measurement system Measuring light has never been easier Background Viso Color correction technology Done spectral color light measurement for 6 years Background Viso Color correction technology Controlling colored lighting made easy with Viso Light measurement made easy First portable complete measurement solution Light measurement made easy What’s inside Universal power input USB to computer Light source power Light measurement made easy • • • • • • • • • • Lumen Peak candela Color temperature CRI Beam angle Angular field distribution Power Power factor Lumen per watt In 30 seconds Light measurement made easy Full automatic just click • • • • Automatic integration time set Automatic adjustment for ambient light Automatic goniometer speed set Automatic beam centering High accuracy goniometer High resolution up to 51200 step per 360 degrees 3 selectable resolutions • • • Low: 50 intensity points Medium: 100 intensity points High: 300 intensity points High accuracy goniometer Automatic quality control for optimum resolution System automatically rescan beam section if resolution is to low due to a narrow beam. Lumen measurement Lumen value calculated using patented spherical method = = The non-circular part of the light distribution is measured and then used to calculate the complete integrated luminous flux. Lumen accuracy How accurate is lumen measurement using viso technology ? Circular B field error Spectrometer error + sensor error + circular field error = Total error = = = = = Lumen accuracy Average accuracy spectrometer intensity error + sensor error + (circular field error type1+ type2+ type3+ type4+ type5) / 5 = total average lumen error = 0,5% + 2% + (1,6%+2,3%+4,6%+7,9%+10,2%) / 5 = Total average lumen accuracy +/- 7,82% Spherical limitation The LightSpion is first measurement system to fully support limited cone measurement. New EU regulation No 1194/2012 requires from September 2013 directional lamps to be specified in lumen limited to a cone of 90° or 120 ° Text from EU regulation — directional lamps with a beam angle ≥ 90° other than filament lamps and carrying a warning on their packaging in accordance with point 3.1.2(j) of this Annex: rated luminous flux in a 120° cone (Φ 120° ) — other directional lamps: rated luminous flux in a 90° cone (Φ 90° ). Example: Lumen is only calculated in a 90° cone (white part) grey part is considered waste light in new EU regulation. Total: 258 lm 90° cone: 201 lm Waste light: 57 lm CRI details Just click on the CRI and get full CRI details including R9 Spectrometer Fully pre-calibrated plug and play solution 80mm Sensor distance: 65cm Factory calibration valid for 2 years Re-calibration can be done at Viso or at Viso certified local distributor. Make custom calibration easily. Factory calibration will always remain intact.
