Product Data Sheet
Introduction
The Bridgelux family of LED Array products delivers high performance, compact and cost-effective solid-
state lighting solutions to serve the general lighting market. These products combine the higher efficacy,
lifetime, and reliability benefits of LEDs with the light output levels of many conventional lighting sources.
The Bridgelux RS Array Series has been specified to enable lamp and luminaire designs with comparable
performance to existing high wattage CFL and HID conventional light sources for retail, commercial,
industrial and street lighting applications.
The Bridgelux RS Array series provides a high performance alternative to conventional solid state
solutions, delivering between 3000 and 4500 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,
enabling excellent beam control for precision lighting. 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 cost-
effective lamp and luminaire designs. Lighting system designs incorporating these LED Arrays deliver
performance comparable to that of a 2x26 Watt CFL, 42-55 Watt CFL, 35-55 Watt low pressure sodium,
70-Watt high pressure sodium or 70-100 Watt metal halide based luminaires and feature increased

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 RS Array Series Product Data Sheet DS15 (06/23/10) Page 4 of 31
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.
Bridgelux RS Array Series Product Data Sheet DS15 (06/23/10) Page 5 of 31
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.

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:
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 (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 Figure 1,
resin area is indicated in yellow).
Product should be firmly secured onto appropriate heat sink by fastening M2.5, M3 or #4 screws on both
sides of the product as illustrated in Figure 16. To ensure proper thermal contact it is important to mount
the LED Array to the heat sink using 4 mounting screws. Bridgelux recommends the use of hard non-
electrically conductive flat washers with lock washers. The recommended center to center spacing for the
four tapped holes for mounting the Bridgelux RS Series Array is shown in Figure 17. 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 LED 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.

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 LED 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 (EQ30, etc.)
x x x x x – designates the base part number (W3000, 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
18.
