Bridgelux RS Array Series Product Data Sheet DS25 (8/30/2013 rev3)

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 at the nominal drive current with case temperature maintained at or below 85°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 comply with the European Union directives on the restriction of hazardous substances in

electronic equipment, namely the RoHS directive. Bridgelux does 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. Please refer to the UL file E350613 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.

CE Recognition

In accordance with the relevant European Union directives, the family of LED Array products conform to the

applicable requirements of the IEC/EN 62031:2008 (LED Modules for General Lighting Safety Specifications)

and IEC 62471:2006 (Photobiological Safety of Lamps and Lamp Systems). Bridgelux maintains a CE

Declaration of Conformity statement on its website and displays the CE mark on product packing labels.

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.

Case Temperature Measurement Point

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.

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.
