Handling Notes for Luminus COBs
Luminus products are designed for robust performance in general lighting applicationꢀ However, care must be taken when handling and
assembling the LEDs into their fixturesꢀ To avoid damaging Luminus COBs please follow these guide linesꢀ
The following is an overview of the application notes detailing some of the practices to follow when working with these devicesꢀ More
detailed information is available on the Luminus web site at wwwꢀluminusꢀcomꢀ
General Handling
Electrical Contact
Devices are made to be lifted or carried with tweezers on two
adjacent corners opposite the contact padsꢀ At no time should
the devices be handled by or should anything come in contact
with the light emitting surface (LES) areaꢀ This area includes the
yellow colored circular area and the ring surrounding itꢀ There
are electrical connections under the LES which if damaged will
cause the device to failꢀ
Luminus COBs are designed with contact pads on their top
surfaceꢀ These pads are clearly marked with + and – polarityꢀ
Wires can be soldered to the contact pads for electrical
connections or other solderless connector products are
availableꢀ
If wires are being soldered to the COB product, we recommend
attaching these wires prior to mounting the devices to a heat
sinkꢀ Please contact Luminus for specific recommendations on
how to solder wires if not familiar with the standard practiceꢀ
Luminus can also offer design recommendations for jigs to
allow easily soldering multiple products in rapid successionꢀ
In addition, the ring frame itself should not be used for moving,
lifting or carrying the deviceꢀ Also do not attach any optics or
mechanical holders to the ring as it is not capable to handle the
mechanical stressꢀ
Static Electricity
Chemical Compatibility
Luminus COBs are electronic devices which can be damaged by
electrostatic discharge (ESD)ꢀ Please use appropriate measures
to assure the devices do not experience ESD during their
handling and or storageꢀ ESD protection guidelines should be
used at all times when working with Luminus COBsꢀ
The resin material used to form the LES can getter hydrocarbons
from the surrounding environmentꢀ As a results, certain
chemical compounds are not recommended for use with the
Luminus productsꢀ Use of these compounds can cause damage
to the light output of the device and may permanently damage
the deviceꢀ Please refer to wwwꢀluminusꢀcom for a list of the
compounds not recommended for use with the Luminus COB
productsꢀ
Storage: Luminus products are delivered in ESD shielded bags
and should be stored in these bags until usedꢀ
Assembly: Individuals handling Luminus COBs during assembly
should be trained in ESD protection practicesꢀ Assemblers
should maintain constant conductive contact with a path to
ground by means of a wrist strap, ankle straps, mat or other ESD
protection systemꢀ
Thermal Interface Material (TIM)
Proper thermal management is critical for successful operation
of any LED systemꢀ Excess operating temperature can reduce
the light output of the deviceꢀ And excessive heating can cause
permanent damage to the deviceꢀ Proper TIM material is a
crucial component for effective heat transfer away from the LED
during normal operationꢀ Please refer to wwwꢀluminusꢀcom for
specific recommendations for TIM solutionsꢀ
Transporting: When transporting the devices from one
assembly area to another, ESD shielded carts and carriers should
be usedꢀ
