Tc point
Tc point LED Line 3R
Tc point LED Line 2R
Tc point LED Line 1R
The Tc test point indicates a reference point for measuring the LED Line
temperature with a thermocouple glued to the PCB surface. This can be used during
the luminaire design to verify that the temperature remains below the maximum
specified temperature for the Tc test point.
The LED Line 1R and 2R comprises an on-module NTC. With the LED line cable 600
with NTC connector you can connect the designated Xitanium driver. The NTC can
then be used for thermal protection of the LED line. When the threshold value is
exceeded the output power will be automatically tuned down. This is done to keep
the lifetime as specified. The threshold is fixed and cannot be changed. When
designing and installing the luminaire according to this design in guide, the threshold
value will not be exceeded.
Mechanical fixation for LED Line 3R, 2R and 1R.
Screws
The Philips Fortimo LED Line 3R has four holes for fixing the LED Line to the
luminaire. Each LED Line has four holes for M4 (or size 8) screws. To ensure
optimum thermal contact with the luminaire (and therefore optimum lifetime) we
recommend all screw holes are used. To ensure the electrical isolation when using
metal screws, the diameter of the screw head (and optional metal washer) must not
exceed 8 mm.
The LED Line 2200lm 1R has six holes for mounting the module to a luminaire.
There are also six holes available for mounting optics. The electrical isolation distance
around these holes is not suitable for metal screws. When using these holes with
metal screws, apply isolating washers.
The LED Line 1250lm 2R has five holes for mounting the module to a luminaire.
There are also two optional holes available for mounting. These holes can also be
used for mounting optics.
Screw type and torque
The maximum torque that should be applied depends on the screw type and
luminaire material. The fasteners used to secure the LED Line to a heat sink must be
tightened with a torque in accordance with the table below.

Optics
Luminaire manufacturers have the freedom to design their own (secondary) optics.
No primary optics have been added to the LED Line to ensure optimum lm/W
efficiency of the system.
