        Automotive free form reflector.

        Automotive Low Beam

        This application is for the design of a low beam reflector. The application has a radio button toggle
        that changes the setup of the reflector to meet different cutoff style beam patterns. The beam
        pattern types in this application are fog beams, SAE (FMVSS 108 VOL/VOR) low beams, ECE low
        beams, and ECE LHT/RHD low beams.

        Automotive High Beam

        This application is for the design of a high beam reflector. The application has a radio button toggle
        that changes the default spread of the reflector. The narrow spread (high) option is for ECE regula-
        tions, and the wide spread (wide high) option is for US (FMVSS 108) regulations.

    Automotive Signal Beam

    This application creates a signal beam reflector. The application has a radio button toggle that
    changes the spread settings of the reflector to achieve the two most common types of signal beam
    patterns. This application is good for all kinds of signal functions (e.g. stop, turn, tail).




                                                  Figure 3:


    Automotive Low Beam (H4 - Hs1 - D1R - D2R)

    This application is for the design of a low beam reflector. The application has a radio button toggle
    that changes the setup of the reflector to meet different types of cutoff beam patterns. The beam
    pattern types in this application are fog beams, SAE (FMVSS 108 VOL/VOR) low beams, and ECE
    low beams. This low beam application is different from the normal low beam application, as it is
    designed for bulbs (H4, Hs1, D1R, and D2R) with special geometric considerations (i.e. a shield
    within the bulb capsule, or painted on to the bulb).




                                                  Figure 4:


    Automotive High Beam (H4 - Hs1)

    This application is for the design of a high beam reflector. The application has a radio button toggle
    that changes the default spread of the reflector. The narrow spread (high) option is for ECE regula-
    tions, and the wide spread (wide high) option is for US (FMVSS 108) regulations. The application
    also has a radio toggle button to select an upper slant angle for the reflector. The slant angle is
    dependent on the shield within the capsule of the bulb. This high beam application is different from
    the normal high beam application, as it is designed for bulbs (H4 and Hs1) with special geometric
    considerations.

Motorcycle Low Beam

This application is for the design of a motorcycle low beam reflector. The application has a radio
button toggle that changes the setup of the reflector to meet different types of cutoff beam patterns.
The beam pattern types in this application are fog beams, US motorcycle low beams, and ECE mo-
torcycle low beams. This application is specific to motorcycle low beams, and uses a S1, S2, H4,
Hs1, or D1R bulb.




                                              Figure 6:


Motorcycle High Beam

This application is for the design of a motorcycle high beam reflector. The application has a radio
button toggle that changes the default spread of the reflector. The narrow spread (high beam) option
is for ECE regulations, and the wide spread (wide high beam) option is for US regulations. This
application is specific to motorcycle high beams, and uses a S1, S2, H4, or Hs1 bulb.

    ECE Low (5 Facets with Intersection)

    This configuration creates an ECE low beam pattern from a reflector with 5 intersecting facets. Their

This configuration creates an ECE fog beam pattern aimed 1.15 degrees down from a reflector with
5 intersecting facets. Their intersections make transition surfaces between the facets unnecessary.

    pattern from the H4 low beam filament and sample reflector is added to the simulated results from
    the H4 high beam filament and reflector calculated in this application.

    vious application). A pre-calculated beam pattern from the H15 high beam filament and sample
    reflector is added to the simulated results from the H15 DRL filament and reflector calculated in
    this application.

culation and simulation of the H15 high beam, while allowing the user to simulate and examine the

flector is formed from the base grid, and the bottom of the reflector is mirrored from the top. This
application is good for all kinds of signal functions (e.g. stop, turn, tail).

    This configuration creates a signal beam reflector using a rectangular base grid. The top of the re-
    flector is formed from the base grid, and the bottom of the reflector is mirrored from the top. This

    Signal Lamp, polar grid, no steps

    This configuration creates a signal beam reflector using a pre-calculated polar base grid. The con-
    figuration uses the gap setting "step back, no gap, new border"; meaning the reflector doesn't
    have transition surfaces between each facet. The application is good for all kinds of signal functions
    (e.g. stop, turn, tail).

This application creates a projector type headlamp using a faceted MF reflector, rather than a
standard Poly Curve System (PCS) reflector. The configuration makes use of the near field target
plane option within the Macrofocal applications.

ECE Low Beam (Target Light on Road)

This application creates an ECE regulation low beam pattern produced by a MF reflector using a

1.6. Inner Lens Optics
A spread lens with an inner optic behind a smooth, free form outer surface. A rectangular parallel
light source is used. These applications are good for creating lens optics on any free form NURBS
Surface (e.g. tail lamp outer lens surface). Note: These applications only work with a NURBS surface
and not a trimmed surface.

Horizontal Spread

This application creates inner lens optics with vertical flute-like structures. The vertical flutes spread
the parallel light from the rectangular source horizontally. The application is good when horizontal
spread is needed for the beam pattern, but additional vertical spread is not required.

     Horizontal plus Vertical Spread

     This application creates inner lens optics with horizontal flutes and vertical flutes. The horizontal
     and vertical flutes essentially form optics with a pillow-like structure. The pillows spread the parallel
     light from the rectangular source vertically and horizontally. The application is good when a narrow
     spread beam pattern needs to be spread wider to fulfill the required function.

     Horizontal plus Vertical Spread, No Steps

     This application creates inner lens optics with horizontal flutes and vertical flutes. The horizontal
     and vertical flutes essentially form optics with a pillow-like structure. The pillows spread the parallel
     light from the rectangular source vertically and horizontally. The pillows in this configuration don't
     have stepped transition surfaces, allowing for a more aesthetically appealing lens optics surface.
     The drawback is that the effectiveness of the pillows is reduced due to the absence of the stepped
     transition surfaces. The application is good when a narrow spread beam pattern needs to be spread
     wider to fulfill the required function.

Horizontal Spread (Concave)

This application creates inner lens optics with vertical flute-like structures. The vertical flutes spread
the parallel light from the rectangular source horizontally. The application is good when horizontal
spread is needed for the beam pattern, but additional vertical spread is not required. This config-
uration is similar to standard horizontal spread lens optics, but the vertical flutes are concave in
structure.

Shifted Spread (Prism)

This application creates inner lens optics with a vertical wedge-like structure. The vertical wedges
shift the parallel light from the rectangular source horizontally. The application is good when part
or all of a beam pattern needs to be shifted horizontally left or right.

     Example of a curved light guiding plate projecting a homogeneous illuminance out the front surface
     of the plate. It uses the FF DotMask Feature at the rear of the parabolic (acrylic/glass) plate. As
     light sources there are three simple geometric LED models arranged in a reflective optical coupler.

     Angel Eyes - with circular light guide

     A circular light pipe with prism structure on the back side along the pipe. The light is coupled into
     the pipe by two LEDs in combination with a collimator optic for both. It can be used for parking
     lamps or position lamps in combination with headlamps.

     5.2. Design Feature
     Design feature objects are stored in the model. They support the design of optical components on
     a logical higher level. All design parameter are stored and can be modified later with an individual
     dialog, which is specific to the class of the particular design feature.

     Complex head lamp with various modules

     A head lamp is designed with various components. Each component is an instance of a design
     feature. There ar 2 half reflectors for a wide light spread. The hot spot zone is created from 3 PCS
     modules with a rectangular lens.

CPC and Inner-Outer Lens Signal Lamp

A signal lamp designed to use one Rebel LED, a CPC style concentrator, inner fresnel lens, and an
outer pillow lens. Each optical component is an instance of a design feature. The beam pattern
produced is a standard signal lamp pattern (stop, turn, tail, etc.). The lamp size is small enough to
be used for motorcycles or truck signaling.
