FHS LENSES SERIES
High efficiency
Available in 4 different beams
Patent Pending
The FHS series offers a complete range of lenses
specially designed for the LUXEON LED from
Lumileds . Both Batwing and Lambertian

LUXEON
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 .
(2)
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
LUXEON
TM
LED. Heat staking the four legs of the
holder to the support provides excellent mechanical
strenght.
Typical applications for the FHS lenses coupled with
the LUXEON LEDs are:
