T-1 (3-mm) Diffused LED Lamps
Description
Features
This family of T-1 lamps is widely used in general-purpose
indicator applications. Diffusants, tints, and optical design
are balanced to yield superior light output and wide viewing
angles. Several intensity choices are available in each color
for increased design flexibility.

a. 1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
b. The dominant wavelength,d, is derived from the CIE chromaticity diagram and represents the single wavelength that defines the color of
the device.
c. Radiant intensity, le, in watts/steradian, may be found from the equation Ie = Iv/v, where Iv is the luminous intensity in candelas and v is the
luminous efficacy in lumens/watt.

Precautions
T-1 (3-mm) Diffused LED Lamps
Lead Forming
The leads of an LED lamp may be preformed or cut to
length prior to insertion and soldering on PC board.
For better control, use the proper tool to precisely form
and cut the leads to applicable length rather than doing
it manually.
If manual lead cutting is necessary, cut the leads after
the soldering process. The solder connection forms a
mechanical ground that prevents mechanical stress
due to lead cutting from traveling into LED package.
Use this method for the hand soldering operation,
because the excess lead length also acts as small heat
sink.
Soldering and Handling
Take care during the PCB assembly and soldering
process to prevent damage to the LED component.
LED component may be effectively hand soldered to
PCB. However, do this under unavoidable
circumstances, such as rework. The closest manual
soldering distance of the soldering heat source
(soldering iron’s tip) to the body is 1.59 mm. Soldering
the LED using soldering iron tip closer than 1.59 mm
might damage the LED.

a. The preceding conditions refer to measurement with a
thermocouple mounted at the bottom of the PCB.
b. Use only bottom pre-heaters to reduce thermal stress
experienced by LED.
Broadcom
NOTE:
1. PCBs with different size and design (component
density) will have a different heat mass (heat capacity).
This might cause a change in temperature experienced
by the board if the same wave soldering setting is used.
Therefore, recalibrate the soldering profile again before
loading a new type of PCB.
2. Take extra precautions during wave soldering to ensure
that the maximum wave temperature does not exceed
250°C and the solder contact time does not exceed 3s.
Over-stressing the LED during the soldering process
might cause premature failure to the LED due to
delamination.
Apply ESD precautions on the soldering station and
personnel to prevent ESD damage to the LED
component that is ESD sensitive. Refer to Broadcom
application note AN 1142 for details. The soldering iron
used must have a grounded tip to ensure electrostatic
charge is properly grounded.
Recommended soldering condition.
Set and maintain wave soldering parameters according
to the recommended temperature and dwell time.
Perform daily checks on the soldering profile to ensure
that it always conforms to the recommended soldering
conditions.
Loosely fit any alignment fixture that is being applied
during wave soldering and do not apply weight or force
on the LED. Use nonmetal material because it absorbs
less heat during the wave soldering process.
At elevated temperature, LED is more susceptible to
mechanical stress. Therefore, allow the PCB to cool
down to room temperature prior to handling, which
includes removal of alignment fixture or pallet.
If PCB board contains both through-hole (TH) LED and
other surface-mount components, solder surface-mount
components on the top side of the PCB. If the surface
mount must be on the bottom side, solder these
components using reflow soldering prior to the insertion
of the TH LED.
The recommended PC board plated through holes
(PTH) size for LED component leads follows.
