Handling Notes for Luminus COBs
Luminus products are designed for robust performance in general lighting applications; however, care must be
taken when handling and assembling the LEDs into their fixtures. To avoid damaging Luminus COBs, please follow
these guidelines. The following is an overview of the application notes detailing some of the practices to follow
hen working with these devices. More detailed information is available on the Luminus website at
www.luminus.com
General Handling
Devices are made to be lifted or carried with tweezers on two “mouse bite” locations. At no time should the
devices be handled by or should anything come in contact with the light emitting surface (LES) area. There are
electrical connections under the LES which, if damaged, will cause the device to fail.
Static Electricity
LEDs 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 storage. ESD protection
guidelines should be used at all times when working with LEDs.
Storage: Luminus products are delivered in ESD shielded bags and should be stored in these bags until used.
Assembly: Individuals handling LEDs during assembly should be trained in ESD protection practices. Assemblers
should maintain constant conductive contact with a path to ground by means of a wrist strap, ankle straps, mat, or
other ESD protection system.
Transporting: When transporting the devices from one assembly area to another, ESD shielded cards and carriers
should be used.
Electrical Contact
Luminus COBs are designed with electrical contact pads on their top surface. These pads are clearly marked with
“+” and “-“ polarity. Wires can be soldered to the contact pads for electrical connections or other solderless
connector products are available. If wires are being soldered to the COB product, we recommend attaching these
wires prior to mounting the devices to a heat sink. Please contact Luminus for specific recommendations on how
to solder wires if not familiar with the standard practice. Luminus can also offer design recommendations for jigs
to enable easy soldering of multiple products in rapid succession.
Chemical Compatibility
The resin material used to form the emitters inside the LES can getter hydrocarbons from the surrounding
environment. As a result, certain chemical compounds are not recommended for use with Luminus products. Use
of these compounds can cause damage to the light output of the device and may permanently damage the device.
Please refer to www.luminus.com for a list of the compounds not recommended for use with Luminus COB
products.
Thermal Interface Material (TIM)
Proper thermal management is critical for successful operation of any LED system. Excess operating temperature
can reduce the light output of the device, and excessive heating can cause permanent damage to the device.
Proper TIM material is a crucial component for effective heat transfer away from the LED during normal operation.
Please refer to www.luminus.com for specific recommendations for TIM solutions.
Human Eye Safety
Caution must be taken not to stare at the light emitted from Luminus LEDs, as severe eye damage may occur.
