<\/a>EU 2013 Energy label classification<\/h3>\n

Since Sept 2013 these labels<\/a> will be needed.<\/p>\n

Important for the energy classification are the corrected rated power and the useful luminous flux.
\nThe measured rated power is 19.9 W and might need to be corrected. The correction is dependent from the lamp type and whether or not the lamp control gear is included or not. The choice for this lamp is the following classification: Lamps with own control gear (external or internal)<\/b>. As a result the corrected rated power becomes: 19.9 W.
\nThe luminous flux measured is 2339 lm. The classification of this lamp needed to determine the useful flux is: Other directional lamps<\/b>. Then the useful flux becomes 2247 lm. Now a reference power can be calculated.<\/p>\n

The energy efficiency coefficient is P_corr \/ P_ref = 0.12.<\/p>\n

<\/a>Eulumdat light diagram<\/h3>\n

The light diagram giving the radiation pattern.<\/em><\/p>\n

The light diagram indicates the beam in the C0-C180 plane and in the plane perpendicular to that, the C90-C270 plane. These beams are equal as the lamp has symmetry over its first axis (the vertical axis).<\/p>\n

When using the Ev or Iv values per inclination angle, the beam angle<\/a> can be computed, being 42 deg for the C0-C180 plane and 42 deg for the C90-C270 plane.<\/p>\n

This plot shows per inclination angle the intensity measurement results for each turn angle at that inclination angle. There normally are differences in illuminance values for different turn angles. However for further calculations the averaged values will be used.<\/p>\n

<\/a>Luminous flux<\/h3>\n

With the averaged illuminance data at 1 m distance, taken from the graph showing the averaged radiation pattern, it is possible to compute the luminous flux<\/a>.<\/p>\n

The result of this computation for this light spot is a luminous flux of 2339 lm.<\/p>\n

<\/a>Luminous efficacy<\/h3>\n

The luminous flux being 2339 lm, and the consumed power of the lamp being 19.9 Watt, results in a luminous efficacy of 118 lm\/Watt.<\/p>\n

<\/a>Electrical properties<\/h3>\n

This current waveform has been checked on requirements posed by the norm IEC 61000-3-2:2018. This norm contains requirements for lamps with a power 5 W, 5 – 25 W and > 25 W. This lamp consumes 19.9 W.
\nNOTE: standard only applies to lamps with supply voltages higher than 220 V AC.<\/p>\n

Inrush current<\/h3>\n

The inrush current<\/a> has been measured for different voltage start angles; from 0 – 170 degrees with a 10 degrees step. The current- and voltage values have been acquires at a sample speed of 39.9 kS\/s. Then this data has been fed into a second order 2kHz low pass Butterworth filter. This removes the current spikes that do not represent relevant values.

\"\"<\/a><\/p>\n

CRI of the light of this lightbulb.<\/em><\/p>\n

This value of 81 indicates how well the light of this lamp can render well a set of reference colors, this in comparison with the light of a reference source (for color temperatures 5000K a black radiator is used as reference and for color temperatures 5000K the sun or the light outside during the day).<\/p>\n

The value of 81 is bigger than the value of 80 that is considered as a minimum for working areas in general.<\/p>\n

Note: the chromaticity difference is -0.0001 and indicates the distance to the Planckian Locus<\/a>. There is a value mentioned of max 5.4E-3 in section 5.3 of CIE 13.3-1995 however no further explanation of it.

<\/a>Voltage dependency<\/h3>\n

The dependency of a number of lamp parameters on the lamp voltage is determined. For this, the lamp voltage has been varied and its effect on the following light bulb parameters measured: illuminance E_v [lx], the lamppower P [W] and the luminous efficacy [lm\/W] (this latter is estimated here by dividing the found E_v value by P).<\/p>\n

\"\"<\/a><\/p>\n

Lamp voltage dependencies of certain light bulb parameters<\/em><\/p>\n

There is no (significant) dependency of the illuminance when the power voltage varies between 200 – 250 V .
\nThere is no (significant) dependency of the consumed power when the power voltage varies between 200 – 250 V .<\/p>\n

When the voltage varies abruptly with + or – 5 V then this results in a variation of the illuminance of maximally 0.1 %. This difference in illuminance is not visible (when it occurs abruptly).<\/p>\n

<\/a>Warm up effects<\/h3>\n

After switch on of a cold lamp, the effect of heating up of the lamp is measured on illuminance E_v [lx], the lamppower P [W] and the luminous efficacy [lm\/W].<\/p>\n

A CS value of 0.1 has hardly any effect and a value > 0.3 has an effect (0.7 is the maximum, saturated, value).

Here an LED luminaire from . The measurements from OliNo show that the lamp emits a neutral white light with a color temperature of 4012 K. The lamp consumes 19.9 W and has a luminous flux of 2339 lm. This results in an efficacy of 118 lm\/W. The lamps energy category label is A++.
