Note 5

Notes: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the

CIE eye-response curve.

2. Luminous Intensity (mcd) is for reference.

3. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

4. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the

single wavelength which defines the color of the device.

5. Reverse voltage (VR) condition is applied to IR test only. The device is not designed for reverse operation.
