Bridgelux LS Array Series
Data Sheet DS 20
BXRB – XXX0360-X, -56C0470-X
Introduction
The Bridgelux family of LED Array products delivers high performance, compact and cost-effective solidstate 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 LS Array Series has been specified to enable lamp and luminaire designs which are
thermally limited to a maximum of 4-5 Watts, including replacement lamps, decorative lighting and white
goods applications.
The Bridgelux LS Array Series provides a high performance alternative to conventional solid state
solutions, delivering between 300 and 470 lumens under application conditions in warm 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 both diffuse and directional lamp replacements for a wide range of applications. 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
performance comparable to that of a 20-40 Watt incandescent, 20-35 Watt halogen and low wattage
compact fluorescent lamps and luminaires and feature increased system level efficacy and service life.
Typical applications include replacement lamps, task lighting, under cabinet, accent, pendant, sconces,
porch, pathway, landscape, portable, and consumer luminaires and white goods.

Product Nomenclature
The part number designation for BXRB product families of Bridgelux LED Arrays is explained as follows:
BXRB–AABCCCC–D–EE–FFF
Where:
B X R B: Designates product family
A A: Designates color
27 for 2700K ANSI Bin
30 for 3000K ANSI Bin
56 for 5600K ANSI Bin
B: Designates minimum CRI
C = 70, E = 80, G = 90
C C C C: Designates nominal flux
0360 = 360 lm
0470 = 470 lm
D: Designates configuration options, specific to each array family
E E: Designates color binning
00 = Full ANSI bin, 7 SDCM
03 = 3 SDCM binning option
F F F: Designates wiring options, not applicable for LS Arrays
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).

UL Recognition
Bridgelux secures UL Recognition for all the LED Array products. We continue to add arrays as they are
recognized by UL. Please refer to the UL file E333389 for the latest list of UL Recognized Arrays.
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 in accordance with IEC – EN62471
Photobiological Safety of Lamps and Lamp Systems specification. Bridgelux LED Arrays are classified as
Risk Group 1 (Low Risk) when operated at or below the rated test current. Please use appropriate
precautions. It is important that employees working with LEDs are trained to use them safely.
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 2, 3 and 4.
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 Figure 5 and 6 and from the current vs. voltage characteristics shown in Figures
10 and 11. The typical performance at common drive currents is also summarized in Table 7.

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 color.
Bridgelux LED Arrays are labeled using a 2-digit alphanumeric bin code. This bin code is printed on the
back of each LED Array in the following format:
AB
Where:
A B – designates color bin (P3, P4, Q3, etc.)
All product packaged within a single tube are of the same color bin (or bin code). Using these codes it is
possible to determine the best product utilization to deliver the consistency required in a given application.
