SURFACE MOUNT DEVICE LED
Part No. : L-C150KRCT
REV:A / 0
1. Luminous intensity is measured with a light sensor and filter combination that
proximities the CIE eye-response curve.
2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous
3. The dominant wavelength λd 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 use a wrist band or
anti-electrostatic glove when handling the LED. All devices, equipment and machinery
must be properly grounded.
5. Major standard testing equipment by “Instrument System” Model : CAS140B Compact
Array Spectrometer and “KEITHLEY” Source Meter Model : 2400.
