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 DS17 September 8, 2011 Page 3 of 31 UL Recognition Bridgelux has UL Recognition for all the LED Array products listed in this data sheet. 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 Do not touch the optical area of the LED Array. Avoid any contact with the optical area. Applying stress to the yellow phosphor resin area can result in damage to the LED Array. Optics and reflectors must not be mounted in contact with the white phosphor resin area or the white ring that surrounds the yellow phosphor area. Using the white ring to secure optics can result in damage to the LED Array as the ring is not designed to act as a mechanical locating feature. Optical devices may be mounted on the top surface of the LED Array substrate outside of the white ring maximum OD as specified in the product data sheet. Use the mechanical features of the LED Array substrate edges and/or mounting holes to locate and secure the optical device as needed. 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. CAUTION: CHEMICAL EXPOSURE HAZARD Exposure to some chemicals commonly used in luminaire manufacturing and assembly can cause damage to the LED Array. Please consult Application Note AN11 for additional information. Bridgelux ES Array Series Product Data Sheet DS17 September 8, 2011 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 1°C, 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 color. Bridgelux LED Arrays are labeled using a 3-digit alphanumeric bin code. This bin code is printed on the back of each LED Array in the following format: BCD Where: B C – designates color bin (P3, P4, Q3, etc.) D – designates color rendering index (0, A, B, C, etc) All product packaged within a single tube are of the same 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.

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 16. 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.

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: ABCD BXRA–xxxxx EFGHJ–WWYY Where: B C D – designates the bin code (Q30, etc.) x x x x x – designates the base part number (W3000, etc.) E F G H J or E F G H J K– designates the production lot code (12345, etc.). The Lot Code may be a five or six character number. 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. Figure 17: Tube Label Example Where: X X X X X – designates the base part number (W3000, etc.) B C D – designates the bin code (Q30, etc.) E F G H J or E F G H J K – designates the production lot code (12345, etc.). The lot code may be a five or six character number. W W Y Y – designates the date code (production week and production year, 0210, etc.) Z Z – designates the quantity (10 products per tube).

One tube is loaded per bag, resulting in an SPI of 10. 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 18. Figure 18: Bag Label Example Where: X X X X X – designates the base part number (W3000, etc.) B C D – designates the bin code (Q30, 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 Z – designates the quantity (10 products per tube). 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 shown in Figure 19.
