3.1 LED average luminous intensity averagedLEDluminousintensity when measuring a predetermined value from the LED tube distal end surface of the optical detector effective receiving surface (an area of 100mm2) of Too luminous intensity, in units of cd.

CIE standard conditions A (far field). measuring distance 316mm. Corresponding solid angle 0.001sr, symbol as ILEDA.

CIE standard conditions B (near field). measured distance is 100mm. Corresponding solid angle 0.01sr, symbol as ILEDB.

3.2 The total flux totalluminousflux the sum of the flux emitted by the light source to the entire space, symbol Phi, the unit is 1m.

3.3 chromaticity coordinates each tristimulus value than the sum of its.

Note.

1 because three chromaticity coordinates equals 1, so only the two of them is sufficient to determine the chromaticity.

2 in the CIE standard colorimetric system, the chromaticity coordinates by the symbol X, Y, Z represents.

3.4 peak wavelength Maximum spectral power distribution corresponding to a wavelength, lambda P symbols, in units of nm.

3.5 half-peak bandwidth spectralbandwidthathalfintensitylevels Spectral power distribution curve ordinate equal to 1/2 of the peak corresponding to the difference between the two wavelengths, in units of nm.

3.6 main wavelength dominantwavelength (ofacolourstimulus) when the non-specific stimulation and monochromatic color additive mixing ratio in an appropriate stimulation to match the color stimulus considered the single Color stimulus wavelength. Units of symbols lambdad nm. For reference non-color LED and other energy stimulus is white (illuminant
