Photometric and Electrical Measurement
Total light output (luminous flux) for the 25℃ ±1℃ ambient temperature conditions is measured using a EVERFINE 2.0 m 4
∏ geometry
integrating sphere. Temperature is measured at a position inside the sphere. Spectral radiant flux
measurements are made using Integral Sphere to the detector port of the integrating sphere. Each lamp is operated at rated
voltage in its designated orientation by a CHROMA 61602 AC SOURCE. Each lamp should be stable before measurements
are made as below:
Step 1 Take 3 measurements of the lamp light output at 15 minute interval (total time=30mintues.)This time period is in addition
to the recommended pre-burning time.
Step 2 Calculate the percent difference between the maximum measured value and the minimum measured value for the three
consecutive measurements.
Step 3 if the value calculated in Step 2 does not exceed 0.5 percent, the lamp is considered stable.
Luminous flux, chromaticity coordinates, correlated color temperature and color rendering index for each lamp are calculated
from the spectral radiant flux measurements taken at 2 nm intervals over the range 380 to 780 nm by EVERFINE HASS-2000.
The calibration of the sphere photometer-spectrometer system is traceable to the NIM China by a calibrated halogen
incandescent lamp. Lamp efficacy (lumens per watts) for each lamp model is computed based on the revised luminous flux
result. Electrical measurements including voltage, current, power and power factor are measured using the YOKOGAWA
WT310 digital power Meter.
The total uncertainty of the light output measurements is estimated, at the 95% confidence level, not to exceed ±1.12% over
the wavelength range 380-780 nm.
Luminious Intensity
A Everfine GOR-5000 Goniophotometer was used to measure the intensity at each angle of distribution, Luminous intensity (cd)
is measured within each vertical plane at a 5° vertical angle increment (maximum) from 0° to 180° Luminous intensity (cd),
measurements repeated in vertical planes about the lamp (polar) axis in maximum increments of 22.5° from 0° to 180°, and
export the intensity (cd) with excel format. The test distance is 25meters from the Goniophotometer to the detector
