Bridgelux LS Array Series Product Data Sheet DS14 (03/14/11) Page 3 of 30 Product Nomenclature The part number designation for Bridgelux LED Arrays is explained as follows: B X R A – A B C D E – R R R R R Where: B X R A – designates product family A – designates color, C for Cool White and W for Warm White B C D – designates LED Array product flux, 024 for a 240 lumen array, 026 for a 260 lumen array and 036 for a 360 lumen array 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 LS Array Series Product Data Sheet DS14 (03/14/11) Page 4 of 30 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 in accordance with IEC specification EN62471; Photobiological Safety of Lamps and Lamp Systems. Bridgelux LED Arrays are classified as Risk Group 1 (Low Risk) when operated at or below their 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.

Bridgelux LS Array Series Product Data Sheet DS14 (03/14/11) Page 5 of 30 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.

Bridgelux LS Array Series Product Data Sheet DS14 (03/14/11) Page 21 of 30 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.

Bridgelux LS Array Series Product Data Sheet DS14 (03/14/11) Page 24 of 30 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 or #4 screws on both sides of the product as illustrated in Figure 21. The recommended center-to-center spacing for these the two tapped holes for mounting screws is 17.87 ± 0.10mm. 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.
