solutions, delivering between 400 and 2000 lumens under application conditions in warm, neutral and
cool white color temperatures. These compact high flux density light sources deliver uniform high quality
illumination without pixilation or the multiple shadow effect caused by LED component based solutions.
To simplify system design for appropriate light output, Bridgelux LED Arrays are specified to deliver
performance under typical use conditions.
These integrated plug and play solutions reduce system complexity and enable miniaturized costeffective lamp and luminaire designs. Lighting system designs incorporating these LED Arrays deliver
comparable performance to that of 20-100 Watt incandescent and halogen, 7-42 Watt compact
fluorescent, and 18-50 Watt HID based luminaires and feature increased system level efficacy and
service life. Typical applications include replacement lamps, task, accent, spot, retail, track, down light,
low bay, wide area, security, wall pack and street lighting.

Product Nomenclature
The part number designation for Bridgelux LED Arrays is explained as follows:
BXRA–ABCDE–RRRRR
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 LED Array product flux, 04 for a 400 lumen array, 08 for a 800 lumen array, 12
for a 1200 lumen array, and 20 for a 2000 lumen array
D E – designates product family
R R R R R – used to designate product options, 00000 by default
The base product part number (BXRA-ABCDE) is indicated on each individual unit, printed on the bottom
of the LED 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 rated forward test current. This performance
assumes constant current operation with case temperature maintained at or below 70°C. For use beyond
these typical operating conditions please consult 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 hazardous
substances in electronic equipment, namely the RoHS directive. Bridgelux will not intentionally add the
following restricted materials to LED Array products: lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
Bridgelux ES Array Series Product Data Sheet DS11 (06/23/10)

UL Recognition
Bridgelux product became UL Recognized on 31 March, 2010. Please refer to the UL file E333389.
Bridgelux uses UL Recognized materials with suitable flammability ratings in the LED Array to streamline
the process for customers to secure UL listing of the final luminaire product. Bridgelux recommends that
luminaires are designed with a Class 2 Driver to facilitate the UL listing process.
Minor Product Change Policy
The rigorous qualification testing on products offered by Bridgelux provides performance assurance.
Slight cosmetic changes that do not affect form, fit, or function may occur as Bridgelux continues product
optimization.
Cautionary Statements
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 classification of their product.
CAUTION: RISK OF BURN
Do not touch the LED Array or resin area during operation. Allow the LED Array to cool for a sufficient
period of time before handling. The LED Array may reach elevated temperatures 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 inaccurate 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 temperature measurement location in a manner which closely ties it to
the true case temperature of the LED Array under steady state operation. Deviations between thermal
measurements taken at the point indicated and the back of the LED Array differ by less than 1°C,
providing a robust method to testing thermal operation once the product is installed.

Typical Performance at Alternative Drive Currents
The Bridgelux LED Arrays are tested and binned against the specifications shown in Tables 1, 2 and 3.
Customers also have options to drive the LED Arrays at alternative drive currents dependent on the
specific application. The typical performance at any drive current can be derived from the flux vs. current
characteristics shown in Figures 8-12 and from the current vs. voltage characteristics shown in Figures
16-27. The typical performance at common drive currents is also summarized in Table 6 for warm white
products, Table 7 for neutral white products and Table 8 for cool white products.

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 or application,
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 Array in the following format:
ABCD
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 (or bin code).
Using these codes it is possible to determine the best product utilization to deliver the consistency
required in a given application.
Luminous Flux Binning Information
The table below lists the standard photometric luminous flux bins for Bridgelux LED Arrays (tested and
binned at the indicated test current). Although several bins are outlined, product availability in a particular
bin varies by product and production run. Please contact your Bridgelux sales representative for further
information regarding product availability. All production testing and binning (both flux and color binning)
is conducted under pulsed test conditions at Tj = 25°C.

Mechanical Assembly and Handling
Recommended assembly is illustrated below.
When handling parts, please avoid contacting and do not apply stress to the resin area (see Figures 1
and 2, resin area is indicated in yellow).
Product should be firmly secured onto appropriate heat sink by fastening M2.5 or #4 screws on both sides
of the product as illustrated in Figure 41. The recommended center-to-center spacing for these the two
tapped holes for mounting screws is 19.20 ± 0.05mm for hexagonal star products and 26.92 ± 0.10mm for
rectangular array products. Bridgelux recommends the use of hard non-electrically conductive flat
washers with lock washers. Refer to Application Note AN11 – Handling and Assembly of Bridgelux LED
Arrays, for more details.
A thin layer of thermal grease should be applied to the bottom surface of the LED Array, between the
bottom of the array and the heat sink. All air gaps and voids between 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.
Figure 41: Recommended Assembly Method
Drawing Not to Scale
For the hexagonal star products, preferred screw mounting locations are indicated in Figure 42.

Locations for Hexagonal Star Products

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:
ABCD
BXRA–xxxxx
EFGHJ–WWYY
Where:
A B C D – designates the bin code (LQ30, etc.)
x x x x x – designates the base part number (W0802, etc.)
E F G H J – designates the production lot code (12345, etc.)
W W Y Y – designates the date code (production week and production year, 0210, etc.)
Individual Bridgelux LED Arrays are packaged 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 shown in Figure
43.
Figure 43: Tube Label Example
Where:
X X X X X – designates the base part number (W0802, etc.)
A B C D – designates the bin code (LQ30, etc.)
E F G H J – designates the production lot code (12345, etc.)
W W Y Y – designates the date code (production week and production year, 0210, etc.)
Z Z – designates the quantity (25 products per tube for hexagonal stars, 20 for rectangles).
Bridgelux ES Array Series Product Data Sheet DS11 (06/23/10)
Page 40 of 45
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 hexagonal star products and 20 for rectangular product
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 bag label is shown in Figure 44.
Figure 44: Bag Label Example
Where:
X X X X X – designates the base part number (W0802, etc.)
A B C D – designates the bin code (LQ30, etc.)
E F G H J – designates product lot code
W W Y Y – designates the date code (production week and production year, 0210, etc.)
Z Z – designates the quantity (25 products per tube for hexagonal stars, 20 for rectangles).
Bags of Bridgelux LED Arrays are packaged in boxes prior to shipment. Multiple bags are packaged into
a box. All products packaged within a box are of the same base part number. Each box is labeled with
the information required for effective inventory management. An example of the box label is shown in
Figure 46.
