LUXEON CoB
High uniformity and high efficiency array
Introduction
Philips Lumileds’ high uniformity array solution is a new breakthrough in efficacy for arrays.
Due to its industry leading small Light Emitting Surfaces (LES), the CoB array is very easy to
work with and will enable easier and less expensive designs.
All LUXEON CoBs are available in a single 3-step as well as a single 5-step MacAdam
Ellipse, ensuring uniform optical performance in the application. Next to that, LUXEON
CoB’s are all hot-tested at 85°C—real world operating conditions— which means that
luminaire design is simplified and testing can be minimized.
This document contains the performance data needed to design and engineer LUXEON
CoB based applications.

Philips Lumileds Preliminary Datasheet LUXEON CoB V0.1 (2013-03-19)
Product Nomenclature
LUXEON CoB is tested and binned hot at Tj = 85ºC with a current pulse duration of 20ms.
The part number designation is explained as follow:
LHCA–BBCC–DDEE
Where:
A
– designates the generation of the product family
BB
— designates ANSI color point (e.g. 30 for 3000K)
C C
— designates minimum CRI level (e.g. 80 for minimum 80 CRI)
D D E E
— designates color product configuration (e.g. 1203 for the 1000-2000lm package)
Therefore 3000K, 80 CRI LUXEON CoB product will be:
LXCB–3080–1203
Average Lumen Maintenance Characteristics
Lumen maintenance for solid-state lighting devices (LEDs) is typically defined in terms of the percentage of
initial light output remaining after a specified period of time. Operating
conditions will be further validated and
disclosed at the time of product launch.
Observation of design limits included in this data sheet is required in
order to achieve this projected lumen maintenance.
Environmental Compliance
Philips Lumileds is committed to providing environmentally friendly products to the solid-state lighting market.
LUXEON CoB is compliant to the European Union directives on the restriction of hazardous substances in
electronic equipment, namely the RoHS and REACH directives. Philips Lumileds will not intentionally add the
following restricted material to the LUXEON CoB: lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
