1. Centre of rotation Alignment of the lamp Aligning the sample lamp is key in ensuring precise measurements Specific tools designed to align the lamp relative to the centre of rotation namely centre alignment bracket and an aligning laser box are included with the LabSpion system First place the centre alignment bracket in the middle of the rotating opening It is designed in such a way that it will always sit in the middle of the opening Then place the laser box on the base of the LabSpion and make sure it is centred relative to the centre bracket as shown in the pictures below alignment bracket centred laser box 22 LabSpion user guide The laser box will shoot two perpendicular beams upwards which form a crossing That is the exact centre of rotation so the measuring lamp has to be aligned accordingly It is important to notice that sometimes it can be a little tricky figuring out the centre of the lamp For example in the picture above the centre of the lamp is the plane of the LED chip the rest is just metalic housing Another example is in the picture below a flat LED panel the laser beam is just on the brink of it turned on laser 23 LabSpion user guide Adjustment of the lamp holder arm There can be cases when a measuring lamp is very Spacious for instance a high bay lamp The large horizontal dimensions of the lamp will make it impossible to align the lamp with the centre of rotation2. rrrnrnerrnnnnevnnnn Ibsen Photonics FREEDOM EEE ENE Custom viso high sensitive transmission grating Spectrometer range srrnnnnnnnnnnnnnnnnn 360 830nm 1024 pixels Spectrometer detector rrrrrrrnnnrnrrrrrnnnrnvvnnnnnn SONY ILX511B Calibration srrrernnnnnnrr Fully calibrated plug and play solution Re calibration ccccsscccsseeeeeeees Every 1 year Maximum 2 years Control and interface COMO MEM ACC aja USB 2 0 COMMON CONMECION sdear a USB B Connections AC power in power supply ccccseeeeeeeeeeeeeeeeeeseeeeeees IEC 3 pin AC power out lamp rrrrrrnnnrnvrrrrnnnnnvnvrrnnnnnrrnnnnnn Universal socket Light Source adaptors rrrrnnnnnnrrnnnnnnnr E27 E14 B22 GU10 gg eae Re ae ee USB B Approvals Power Supply ccccsseeeeeeeeeeeeeeees cUL UL CE CCC TUV FCC Power analyzer LabSensor rrrrnrrnnrrnvvnrrnnnnnvrnrnnnnnennnnnnsnne CE Ordering information VAD SIO IN eee P N LABSPO01 55 LabSpion user guide

26. power control In some cases it is necessary to control the power of the light source manually For example when measuring flash light on batteries as the LabSpion s power analyser won t be able to turn on and off the light source automatically Another example could be a low voltage light source such as LED chips The external power supply of such chips has low response time when turned on and off therefore it would lead to an inaccurate result of the ambient light level To enable the manual power control select Setup gt Power control and select manual power control Setup power control C Automatically tum power on off Manually tum power on off Save Cancel When the manual power control has been selected the Viso Light Inspector will ask you to manually turn on and off the light source when necessary as shown below 35 LabSpion user guide Manual integration time setup In some rare cases it could be desirable to er le integration time of the photo hac spectrometer manually One case could be when measuring a light source emitting most of the light to the sides instead of in the central direction As the automatic setup of the integration time is done in the centre at 0 degrees the integration time would be too high resulting in saturation of the photo spectrometer and leading to an inaccurate measurement The integration time of the photo spectrometer can be set manually by selecting Se
27. r Ra The value of CRI shows how much the spectrum of a light source resembles that of the Sun thus the ability of the light source to reproduce the colours of an object as if it were illuminated by the Sun The CRI is calculated with the help of the standard test colours which examine the chromatic adaptation of light The standard set consists of 15 test colours but only the first 8 of them known as R1 R8 are used to calculated the CRI whereas the remaining R9 R15 are typically not used However sometimes LED lights do not have a red light component which is considered in the R9 measurement that is why it is becoming more common to include the R9 measurement as well R9 R15 values can be view in the CRI details window which is opened by clicking on the CRI bar or selecting View gt CRI details CRI details R1 R15 R1 R8 CRI 77 6 93 85 75 74 73 A Ri R n According to the colours table above we can see that the red light of R9 is rather low compared to the rest of the 43 LabSpion user guide values In some cases R9 can even be negative due to particularly low levels of the red light 44 LabSpion user guide Example 1 Shows a standard tungsten lamp Its continuous spectrum has the closest resemblance to the Sun therefore the CRI values are the highest Example 2 Shows a Philips LED bulb with a low red R9 value Example 3 Shows a standard LED bulb with a negative r
28. stallation should be adjusted accordingly The excess current will result in power loss due to cables heating etc A general rule is the following a 10W light source with a PF 0 5 must be connected to an installation capable of supplying 20W The corresponding formula reads installation W Power PF 41 LabSpion user guide Example 1 Shows a standard 60W tungsten bulb with an ideal PF of 1 0 and a current curve that Is identical to the voltage Example 2 Shows a LED bulb that has a passive Capacitor power supply which results in a high phase shift Power 65 W PF 1 00 Voltage 240 4 V Current 0 272 A Voltage 240 4 V Current 0 016 A between current and voltage thus resulting in a very low power factor of 0 19 Example 3 Shows a LED bulb of a medium quality switch mode driver with a high capacity peak load thus a medium quality power factor of 0 62 Power 5 2 W PF 0 62 Voltage 238 6 V Current 0 035A Example 4 Shows a LED bulb having a switch mode driver with a particularly bad filtering It results ina Voltage 226 8 V Current 0 125A high noise level of the current Therefore this level of noise would probably not be able to pass the EMC noise level requirements 42 LabSpion user guide CRI details The CRI defines the quality of white light it is also known as the Colour Rendering Index o
