Luxeon Flash
Introduction
Luxeon® Flash is a family of ultracompact light sources specifically
designed and tested for use as a camera flash in spaceconstrained,
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
Features
ΠHighest brightness LED flash
ΠVery small emitter size
ΠRadiation patterns optimal for
Camera Flash (with lens)
ΠSmaller than Xenon Strobe
Light
ΠSurface mount technology
ΠSuperior ESD protection
source density characteristics of the Luxeon Flash products will provide
greater amounts of light where needed, enabling higher resolution
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.
Benefits
ΠIntense illumination and long
distance (up to 2m)
ΠEnables higher resolution
pictures in darker environ
ments
ΠSmall emitter size allows for
smaller overall package size
Typical Applications
ΠCameraphones
ΠDigital still cameras
ΠPDAs

Notes for Tables 1 and 2 and Figure 1:
1. Minimum luminous flux performance guaranteed within published operating conditions. Lumileds maintains a tolerance
of ± 10% on flux measurements.
2. Luxeon types with even higher luminous flux levels will become available in the future. Please consult your Lumileds
Authorized Distributor or Lumileds sales representative for more information.
3. Lumileds maintains a tolerance of ± 0.06V on forward voltage measurements.
4. All values assume a junction temperature TJ of 25°C.
5. For flash modes, it is recommended that the drive current be as high as possible (up to 1000 mA) for optimal results.

Typical Axial Intensity (cd) and Illuminance (lux)
vs. Drive Current, TJ = 25ºC
Figure 2.
Notes for Figure 2:
1. High Uniformity and High Intensity Options assume use of the 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.
2.
Uniformity can be tradedoff for increased OnAxis 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.
3.
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.
