The luminous intensity is measured on the mechanical axis of the lamp package.
2θ½ is the off-axis angle where the luminous intensity is ½ the on axis intensity.
The dominant wavelength,
λ
d
is derived from the CIE 1931 Chromaticity Diagram and represents the perceived color of the device.

Precautions
Lead Forming
The leads of an LED lamp may be preformed or cut to
length prior to insertion and soldering into PC board.
If lead forming is required before soldering, care must be
taken to avoid any excessive mechanical stress induced to
LED package. Otherwise, cut the leads of LED to length
after soldering process at room temperature. The solder
joint formed will absorb the mechanical stress of the lead
cutting from traveling to the LED chip die attach and
wirebond.
During lead forming, the leads should be bent at a point at
least 3 mm from the base of the lens. Do not use the base
of the lead frame as a fulcrum during forming. Lead
forming must be done before soldering at normal
temperature.
It is recommended that tooling made to precisely form
and cut the leads to length rather than rely upon hand
operation.
Wave soldering parameter must be set and maintained
according to recommended temperature and dwell time in
the solder wave. Customer is advised to periodically check
on the soldering profile to ensure the soldering profile
used is always conforming to recommended soldering
condition.
If necessary, use fixture to hold the LED component in
proper orientation with respect to the PCB during
soldering process.
Proper handling is imperative to avoid excessive thermal
stresses to LED components when heated.
Therefore, the soldered PCB must be allowed to cool to
room temperature, 25 °C, before handling.
Special attention must be given to board fabrication,
solder masking, surface plating and lead holes size and
component orientation to assure solderability.
Recommended PC board plated through-hole sizes for
LED component leads:
LED Component
Lead Size
0.50 x 0.50 mm
(0.020 x 0.020 inch)
Diagonal
0.718 mm
(0.029 inch)
Plated Through
Hole Diameter
1.050 to 1.150 mm
(0.042 to 0.046 inch)
NOTE
Refer to application note AN1027 for more
information on soldering LED component.
