CXM-14 Product Datasheet
Technology Overview
Luminus Chip-on-Board (COB) LED series offers a complete lighting class solution designed for high performance illumination
applications. The selection covers a wide lumen range from less than 400lm to over 20,000lm, all major color temperatures and can
deliver color rendering greater than 97 at 2700K and 3000K and R9 equal to 95. These breakthroughs allow illumination engineers and
designers to develop lighting solutions with maximum efficacy, brightness and overall quality.
Reliability
Designed from the ground up, the Luminus COB LED is one of
the most reliable light sources in the world today. Having
passed a rigorous suite of environmental and mechanical stress
tests, including mechanical shock, vibration, temperature
cycling and humidity. Only then are the devices qualified for
use in a wide range of lighting application including some of the
most demanding commercial applications. Delivered with fully
qualified LM80 test data and TM21 lifetime results that certify
lumen maintenance at 35,000 hours or more, Luminus COB
LEDs are ready for the toughest challenges.
UL Recognized Compliance
Luminus COB arrays are tested in accordance with ANSI/UL 8750
to ensure safe operation for their intended applications.
REACH & RoHS Compliance
All LED products manufactured by Luminus are REACH and
RoHS compliant and free of hazardous materials, including lead
and mercury.
Understanding Luminus COB LED Test Specifications
Every Luminus LED is fully tested to ensure it meets the high quality standards customers have come to expect from Luminus’ products.
Traceability
Chromaticity Bin Range
Each Luminus COB LED is marked with a 2D bar code that
contains a unique serial number. With this serial number,
Luminus has the ability to provide customers with actual test
data measurements for a specific LED. In addition, the 2D bar
code is linked to manufacturing date codes that enables
traceability of production processes and materials.
Chromaticity binning delivers color consistency for every order.
Standard products are delivered with a 3-step MacAdam ellipse.
This ensures color performance matching in the application. For
the most demanding application, Luminus is one of only a few
companies that can provide a 2-step ellipse bin. These tightly
controlled, small distribution bins provide customers
predictable, repeatable colors.
Testing Temperature
Luminus COB products are measured at temperatures typical for
the LED operating in the fixture. Each device is tested at 85ºC
junction temperature eliminating the need to scale datasheet
specifications to real world situations.

Handling Notes for Luminus COBs
Luminus products are designed for robust performance in general lighting application. 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 when working with these devices. More
detailed information is available on the Luminus web site at www.luminus.com.
General Handling
Electrical Contact
Devices are made to be lifted or carried with tweezers on two
adjacent corners opposite the contact pads. At no time should
the devices be handled by or should anything come in contact
with the light emitting surface (LES) area. This area includes the
yellow colored circular area and the ring surrounding it. There
are electrical connections under the LES which if damaged will
cause the device to fail.
Luminus COBs are designed with 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.
In addition, the ring frame itself should not be used for moving,
lifting or carrying the device. Also do not attach any optics or
mechanical holders to the ring as it is not capable to handle the
mechanical stress.
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
allow easily soldering multiple products in rapid succession.
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 storage. ESD protection guidelines should be
used at all times when working with Luminus COBs.
The resin material used to form the LES can getter hydrocarbons
from the surrounding environment. As a results, certain
chemical compounds are not recommended for use with the
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 the Luminus COB
products.
Storage: Luminus products are delivered in ESD shielded bags
and should be stored in these bags until used.
Assembly: Individuals handling Luminus COBs 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 carts and carriers should
be used.

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.
