10mm圆形大功率系列
Notes:
Luminous intensity is measured with a light sensor and filtercombination that approximates the CIE eye-response curve.2θ1/2
is the o-axis angle where the luminous intensity is 1⁄2the peak intensity.c.
The dominant wavelength (λd) is derived from the CIEchromaticity diagram and represents the single wavelength which defines thecolor of the device.
