FHS SERIES High efficiency Available in 4 different beams

The FHS series offers a complete range of lenses specially designed for the LUXEONTM LED from Lumileds

Both Batwing and Lambertian LUXEONTM radiation patterns are supported.
A software optimized aspheric profile combined to front shaped micro-lens arrays enable the generation of four different lens models: narrow beam, medium beam, wide beam and a special elliptical pattern .
The high collection efficiency reaches the 85% of the total flux emitted from the LED.
Lenses are also available assembled with Fraen’s Universal Lens Holder. The holder assures the proper relative placement between the lens and the LUXEONTM LED. Heat staking the four legs of the holder to the support provides excellent mechanical strength.
Typical applications for the FHS lenses coupled with the LUXEONTM LEDs are:

• Reading Lamps
• Signage
• Street Lighting
• General Illumination
• Most applications where uniformity and high intensity over a wide angle is required
  

Typical beam divergence may change with different color LEDs

Typical Beam Divergence FWHM(3) with Lambertian LED(4)

(3) FWHM full width half maximum is the full angle measured where the luminous intensity is half of the peak value
(4) Typical divergence angle may change with different color LEDs and depends on LED tolerances

(5) Is the on axis luminous intensity measured in candela per lumen (K) with a typical Luxeon LED. Candela per Lumen K=I/F where I is the
intensity measured in candela and F is the total flux of the LEDs under test.
(6) Multiply the candela per lumen value K with the flux of the LED to obtain the expected on axis intensity in candela. Please refer to the Luxeon
datasheet to verify the flux bin.
(7) Luminous Intensity depends on the LED flux binning and LED tolerances. Please refer to the
Luxeon datasheet for more details on flux binning and mechanical tolerances.

(8) Typical illuminance measured in lux per lumen (E) with a typical LUXEONtm LED. Multiply the lux per lumen value E with the
flux of the LED to obtain the expected illuminance in lux.
(9)Illuminance depends on the LED flux binning and LED tolerances. Please refer to the LUXEONtm datasheet to verify the flux bin.
