SURFACE MOUNT DEVICE LED
Part No. : L-T2835WDT-NW1-Q
Notes:
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
intensity.
3. Caution in ESD :
Static Electricity and surge damages the LED. It is recommended use a wrist band or
anti-electrostatic glove when handling the LED. All devices, equipment and machinery
must be properly grounded.
4. Major standard testing equipment by
“Instrument
System” Model : CAS140B Compact
Array Spectrometer and
“KEITHLEY”
Source Meter Model : 2400.
