LUXEON Flash
(R)
Introduction
LUXEON(R) Flash is a family of ultra compact light sources specifically designed and tested for use as a camera flash in space constrained, portable digital imaging applications. The LUXEON Flash products are based on proven LUXEON technology and provide the highest levels of light output available for a solid state light source. The uniquely bright source density characteristics of the LUXEON Flash products will provide greater amounts of light where needed, enabling higher resolu tion pictures to be taken in lower level ambient light environments at greater distances. Camera cell phones, digital still cameras and PDAs can all incorporate LUXEON Flash into sleek designs while maintaining high levels of light output.
Features
Highest brightness LED flash Very small emitter size Radiation patterns optimal for Camera Flash (with lens) Smaller than Xenon Strobe Light Surface mount technology Superior ESD protection
Benefits
Intense illumination and long distance (up to 2m) Enables higher resolution pictures in darker environ ments Small emitter size allows for smaller overall package size
Typical Applications
Camera phones Digital still cameras PDAs

Notes for Tables 1 and 2 and Figures 1 and 2: 1. Minimum luminous flux performance guaranteed within published operating conditions. Philips Lumileds maintains a toler ance of 10% on flux 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. Philips Lumileds maintains a tolerance of 0.06V on forward voltage measurements. 4. All values assume a junction temperature TJ of 25C. 5. For flash modes, it is recommended that the drive current be as high as possible (up to 1000 mA) for optimal results.

Notes for Figures 3 and 4: 1. High Uniformity and High Intensity Options assume use of the Philips Lumileds reference design optic. The design of this optic is available upon request. High Uniformity option is achieved by placing the lens at 0.4 mm from the top of the emitter. This will yield uniformity of 41% (relative to the center) at the horizontal edge and 24% (relative to the center) at the corners. Uniformity can be traded off for increased On Axis Illuminance/Intensity. This is shown in the High Intensity Option and is achieved by placing the optic at 0.7mm from the top of the emitter. In this option, the uniformity is 17% at the horizontal edge and 10% at the corners. Illuminance is inversely proportional to the square of the distance. For example: if the illuminance at 1 meter is 40, then the illuminance at 2 meters is 40/(22) = 10 lux. The illuminance at 3 meters is 40/(32) = 4.4 lux For flash modes, it is recommended that the drive current be as high as possible for optimal results.
