Important aspects
Additional information
LED modules must not be stuck and restuck time and again without replacing the adhesive tape. Damaged adhesive tapes must be
completely removed and replaced by new tapes.
Packaging and transport
LED products from Tridonic are delivered in appropriate packaging. The packaging provides special protection against mechanical
damage and ESD (electrostatic discharge). If you need to transport LED products you should use this packaging.
3.1.2.
Installing the modules
The modules are mounted on a heat sink with 2 bolts per module. In order not to damage the modules only raised head bolts should
be used. The bolts should be selected on the basis of the following dimensions:
Carrier material
The carrier material must have adequate thermal conductivity (e.g. aluminium). The size of the cooling surface depends on the
power of the LEDs, among other things. For information on the cooling surface required, see the appropriate product data
sheet.
_
Adhesive material
The carrier material itself plays an important role in selecting the adhesive material. The crucial factors are the coefficient of
expansion and compatibility with the base material of the LED module board (plastic or aluminium). This must be checked in
the application in terms of long-term stability, surface contamination and mechanical properties.
_
Surface quality
The carrier material must be uncoated (thermal transport, adhesion) and level at the connection points.
_
Installation temperature
To achieve optimum adhesion we recommend you carry out this work at room temperature.
_
Duration, optimum adhesive strengths
Maximum adhesion is achieved within 48 hours at room temperature; the process is accelerated by heat. In actual practice this
means that at the maximum t temperature (approx. 75-85 °C, product-specific) maximum adhesion is reached after about 12
c
hours. During the curing period make sure that there is no tensile load on the adhesive connection of the LED module.
