Luxeon 1Watt StarTechnical Data DS23
Luxeon is a revolutionary, energy efficient and ultra compact new light
source, combining the lifetime and reliability advantages of Light Emitting
Diodes with the brightness of conventional lighting.
Luxeon features one or more power light sources mounted onto an
aluminumcore printed circuit board, allowing for ease of assembly,
optimum cooling and accurate light center positioning.
For tight beams, optional and highly efficient collimating optics
are available.
Luxeon Power Light Sources give you total design freedom and
unmatched brightness, creating a new world of light.
For high volume applications, custom Luxeon power light source designs
are available upon request, to meet your specific needs.
LuxeonTM Emitters can be purchased in reels for high volume assembly. Sample kits are
also available for prototyping and design evaluation. A sample kits contains a strip of 50
taped emitters. To order a sample kit, add a “K” to the
Features• Highest Flux per LED family in the world
Luxeon Star is available in white, green, blue, royalblue, cyan, red, red-orange and amber.

Part Number MatrixColor Star Star/C Star/O[1] Star/IDC[2] Beam Pattern
Blue[3] 3.8 5 Side EmittingRoyal Blue[4] 55 mW 90 mW
Red 30.6 40Amber 23.5 32
Notes:1. Star/O produces a narrow collimated
beam due to the inclusion of thecollimating optic. In red, red-orange,and amber the Star/O listed underlambertian radiation pattern is higher inluminous output, although thecollimated beam pattern is similar tothe Star/O products based on thebatwing emitter.
2. Star/IDC available in the batwingradiation pattern only. The wide angleof optical output from a lambertian orside emitting device results insignificant light loss due to the IDCconnectors in the optical path.
Notes:1. Minimum luminous flux or radiometric
power performance guaranteed withinpublished operating conditions.Lumileds maintains a tolerance of ±10% on flux and power measurements.
2. Flux and power values for Luxeon Starwithout secondary optics. Theefficiency of collimating optics isapproximately 85%. Luxeon types witheven higher luminous flux levels willbecome available in the future. Pleaseconsult your Lumileds AuthorizedDistributor or Lumileds salesrepresentative for more information.
3. Minimum flux value for 470 nmdevices. Due to the CIE eye responsecurve in the short blue wavelengthrange, the minimum luminous flux willvary over the Lumileds’ blue colorrange. Luminous flux will vary from aminimum of 2.9 lm at 460 nm to atypical of 8 lm at 480 nm dueto this effect. Although the luminouspower efficiency is lower in the shortblue wavelength range, radiometricpower efficiency increases aswavelength decreases. For moreinformation, consult the Luxeon DesignGuide, available upon request.
4. Royal Blue product is binned byradiometric power and peak wavelengthrather than photometric lumens anddominant wavelength.

2. Royal Blue product is binned byradiometric power and peakwavelength rather than photometriclumens and dominant wavelength.Lumileds maintains a tolerance of± 2nm for peak wavelengthmeasurements.

Notes:
1. Lumileds maintains a tolerance of± 0.06V on forward voltagemeasurements.
2. Dynamic resistance is the inverse of theslope in linear forward voltage model forLEDs. See Figures 3a and 3b.
3. Measured between 25oC ≤ TJ ≤ 110oCat IF = 350mA.
Notes:
1. Proper current derating must beobserved to maintain junctiontemperature below the maximum. Formore information, consult the LuxeonDesign Guide, available upon request.
2. Measured at IF = 100 µ A. LEDs arenot designed to be driven in reversebias. All products are not sensitive toESD damage ( ±16,000 Volts by HBMcondition).
3. A reduction in maximum storage andoperating temperature is required dueto the acrylic optic.
