7 / 8 page Luxeon Flood 7 Document #: DS24 (10/05) Representative Spatial Radiation Pattern Average Lumen Maintenance Characteristics Lifetime for solidstate lighting devices (LEDs) is typically defined in terms of lumen maintenance—the percentage of initial light output remaining after a specified period of time. Lumileds projects that Luxeon products will deliver on average 70% lumen maintenance at 50,000 hours of operation. This performance is based on independent test data, Lumileds historical data from tests run on similar material systems, and internal Luxeon reliability testing. This projection is based on constant current 350 mA operation per LED (700 mA 12 Up Flood, 1050 mA for 18Up Flood) with junction temperature maintained at or below 90 °C. Observation of design limits included in this data sheet is required in order to achieve this projected lumen maintenance. 0 10 20 30 40 50 60 70 80 90 100 -100 -80 -60 -40 -20 0 20 40 60 80 100 Angular Displacement (Degrees) Batwing Radiation Pattern (without optics) Figure 7a.
