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 70C. 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 3 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 4 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 1C, providing a robust method to testing thermal operation once the product is installed.

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 = 25C.

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 nonelectrically 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.
