Minimum luminous flux or radiometric power performance guaranteed within published operating conditions. Philips Lumileds maintains a tolerance of ± 10% on flux and power measurements. 2. LUXEON types with even higher luminous flux levels will become available in the future. Please consult your Philips Lumileds Authorized Distributor or Philips Lumileds sales representative for more information. 3. Minimum flux value for 470 nm devices. Due to the CIE eye response curve in the short blue wavelength range, the minimum luminous flux will vary over the Philips Lumileds' blue color range. Luminous flux will vary from a minimum of 6.3 lm at 460 nm to a typical of 20 lm at 480 nm due to this effect. Although the luminous power efficiency is lower in the short blue wavelength range, radiometric power efficiency increases as wavelength decreases. For more information, consult the LUXEON Design Guide, available upon request. 4. Royal Blue product is binned by radiometric power and peak wavelength rather than photometric lumens and dominant wavelength. 5. In July 2003 Philips Lumileds announced a secondgeneration white batwing product using a new phosphor deposition process resulting in improved color uniformity, LXHLBW02.

LEDs are not designed to be driven in reverse bias. Please consult Philips Lumileds' Application Brief AB11 for further information. 3. Measured at leads, during lead soldering and slug attach, body temperature must not exceed 120°C. LUXEON emitters cannot be soldered by general IR or Vaporphase reflow, nor by wave soldering. Lead soldering is limited to selective heating of the leads, such as by hotbar reflow, fiber focussed IR, or hand soldering. The package back plane (slug) may not be attached by soldering, but rather with a thermally conductive adhesive. Electrical insulation between the slug and the board is required. Please consult Philips Lumileds' Application Brief AB10 on LUXEON Emitter Assembly Information for further details on assembly methods.

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. Philips 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, Philips Lumileds histor ical data from tests run on similar material systems, and internal LUXEON reliability testing. This projection is based on constant current 350 mA operation 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. LUXEON Emitter DS25 (5/07) 16 Emitter Reel Packaging Figure 9.
