Notes: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the
CIE eye-response curve.
θ
2.
1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
λ
3. The dominant wavelength,
d is derived from the CIE chromaticity diagram and represents the
single wavelength which defines the color of the device.
4. Caution in ESD:
Static Electricity and surge damages the LED. It is recommend to use a wrist band or anti-electrostatic
glove when handling the LED. All devices, equipment and machinery must be properly grounded.
