Bridgelux LED Arrays
Product Data Sheet
Introduction
The Bridgelux family of LED Array products delivers high perform ance, compact and cost-effective solid-
state lighting solutions to serve the general lighting m arket. These products combine the higher
efficiency, lifetime, and reliability benefits of LEDs with the light output levels of many conventional
lighting sources.
Product options are tailored to match light output levels of conventional light sources, deliveri ng between
400 and 2000 lumens under application conditions in cool, neutral and warm white colors. In order to
satisfy system design requirem ents, the Bridgelux LED Arrays are specified to deliver these values hot, or
under assumed typical use conditions, eliminating the need of incorporating additional sources to account
for thermal degradation.
Various configurations are available allowing the product to be optimized on efficacy, CRI, light output,
cost, or a combination of these attributes. These high lumen output integrated sources reduce sy stem
design complexity, enabling miniaturized co st-effective lamp and luminaire designs. Typical applications
include task, accent, spot, track, down light, wide area and securit y lighting.

The part number designation for Bridgelux LED Arrays is explained as follows:
B X R A – A B C D E – 0 0 0 0 0
Where:
B X R A – designates product family
A – designates color, C for Cool White, N for Neutral White, and W for Warm White
B C – designates array product flux, 04 for a 400 lumen array, 08 for a 800 lu men array, 12 for a
1200 lumen array, and 20 for a 2000 lumen array
D E – reserved for future product designations
0 0 0 0 0 – designates the standard product option, reserved for future product designations
The base product part num ber (BXRA-ABCDE) is indicated o n each individual unit, printed on the bottom
of the array.
Average Lumen Maintenance Characteristics
Bridgelux projects that its family of LED Array products will deliver, on average, greater than 70% lumen
maintenance after 50,000 hours of operation at the ra ted forward test current. This perform ance
assumes constant current operation with ca se temperature maintained at or below 70°C. For use b eyond
these typical operating conditions please con sult your Bridgelux sales representative for further
assistance.
These projections are based on a combination of package test data, semiconductor chip reliability data, a
fundamental understanding of package related degradation mechanisms, and performance observed
from products installed in the field using Bridgelux die technology. Bridgelux conducts lumen
maintenance tests per LM80. Observation of design limits is required in order to achieve this projected
lumen maintenance.
Environmental Compliance
Bridgelux is committed to providing environmentally friendly products to the solid-state lighting market.
Bridgelux LED Arrays are compliant to the European Union directives on the restriction of ha zardous
substances in electronic eq uipment, namely the RoHS directive. Bridgelux will not intentionally add the
following restricted materials to array products: lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).

Minor Product Change Policy
The rigorous qualification testing on pro ducts offered by Bridgelux provides performa nce assurance.
Slight cosmetic changes that do not affect form, fit, or function may occur as Bridgelux continues product
optimization.
CAUTION: CONTACT WITH OPTICAL AREA
Contact with the resin area should be avoided. Applying stress to the resin area can result in damage to
the product.
CAUTION: EYE SAFETY
Eye safety classification for the use of Bridgelux LED Arrays is contained in the CIE S 009/E2002
Photobiological Safety of Lamps and Lamp Systems specification. Bridgelux LED Arrays are classified
under section 6 lamp classification as Risk Group 2 (Moderate Risk). Please use appropriate
precautions. It is important that employees working with LEDs are trained to use them safely. Luminaire
manufacturers should refer to CIE S 009/E2002 to establish the classifi cation of their product.
CAUTION: RISK OF BURN
Do not touch the LED Array or resin are a durin g operation. Allow the LED Array to cool for a sufficient
period of time before handling. The LED Array may reach elevated temperature s such that it can burn
skin when touched.
Case Temperature Measurement Point
A case temperature measurement point location is included on the top surface of the Bridgelux LED
Arrays. The location of this measurement point is indicated in the mechanical dimensions section of this
data sheet.
The purpose of this measurement point is to allow the user access to a measurement point closely linked
to the true case temperature on the back surface of the LED array. Once the LED array is installed, it is
challenging to measure the back surface of the array, or true case temperature. Measuring the top
surface of the product can lead to ina ccu rate results due to the poor thermal conductivity of the top layers
of the array such as the solder mask and other materials.
Bridgelux has provided the case tempera t ure measurement location in a manner which closely ties it to
the true case temperature of the array under steady state operation. Deviations between thermal
measurements taken at the point indicated and the ba ck of the LED array differ by less than 1°C,
providing a robust method to testing thermal operation once the product is installed.

Product Binning
Typical manufacturing processes of semiconductor products result in a variation in performance
surrounding the typical data sheet values. In order to minimize variation in the end product of appli cation,
Bridgelux bins its LED Arrays for luminous flux and color.
Bridgelux LED Arrays are labeled using a 4-digit alphanumeric bin code. This bin code is printed on the
back of each LED in the following format:
A B C D
Where:
A – designates flux bin (P, Q, R etc.)
B C – designates color bin (P3, P4, Q3, etc.)
D – reserved for future product designations,
All product packaged within a single tube are of the same flux and color bin combination (o r bin code).
Using these codes it is possible to determine the best product utilization to deliver the consistency
required in a given applicat ion.

Mechanical Assembly and Handling
Recommended assembly is illustrated below.
When handling parts, please do not appl y stress to the resin and avoid any contact on the resin area (see
drawing).
Product should be firmly secured onto appropriate heat sink by fastening M2.5 o r #4 scre ws on both sides
of the product (see drawin g). Bridgelux recommends the use of hard non-electrically conductive flat
washers with lock washers. Refer to Application Note AN11 for more details.
A thin layer of thermal grease should be applied to the bottom surface of the array, between the bottom of
the array and the heat sink. All air gaps and voids bet ween the heat sink and array should be eliminated.
Ensure that sufficient thermal grease is used to cover the entire bottom surface of the array, but not so
much that the thermal grease creeps up to the top of the array.
For the Hexagonal star products, preferred locations for screw mounting are indicated in the fi gure below.

Product Packaging and Labeling
All Bridgelux LED Array products are 100% tested, binned and labeled. Products are labeled by printing
pertinent information on the back side of the array.
The following format is used for labeling the Bridgelux LED Arrays:
A B C D
B X R A – x x x x x
E F G H J – W W Y Y
Where:
A B C D – designates the bin code (LQ30, etc.)
x x x x x – designates the base part number (W0800, etc.)
E F G H J – designates the production lot code (12345, etc.)
W W Y Y – designates the date code (p roduction week and production year, 0509, etc.)
Individual Bridgelux LED Arrays are p ackaged in tubes for shipment. All product packaged within a single
tube are of the same flux and color bin combination (or bin code). Each tube is labeled with the
information required for effective inventory management. An example of the tube label is included below:


E F G H J – designates the production lot code (12345, etc.)
W W Y Y – designates the date code (p roduction week and production year, 0509, etc.)
Z Z – designates the quantity (25 products per tube for hexagonal stars, 20 for re ctangles)
Figure 35: Tube Label Example

Product Packaging and Labeling (continued)
Tubes of Bridgelux LED Arrays are packaged in bags prior to loading into boxes for shipment. One tube
is loaded per bag, resulting in an SPI of 25 for hexago nal star products and 20 for rectangular produ ct
configurations. All products packaged within a single bag are of the same flux and color bin combination
(or bin code). Each bag is labeled with the information required for effective inventory management. An
example of the tube label is included below.
Where:
A B C D – designates the bin code (LQ30, etc.)
x x x x x – designates the base part number (W0800, etc.)
W W Y Y – designates the date code (p roduction week and production year, 0509, etc.)
Z Z Z – designates the quantity (50 products per tube for hexagonal stars, 40 for rectangles)
