Product Summary

The Low Beam Inner Lens is a flat optical component built around a horizontally arranged multi-cavity array. Each tapered, cup-shaped cavity distributes the light of an individual LED, so a slim headlamp module can produce a bright and uniform low beam pattern. Free-form surfaces inside every cavity capture and collimate the incoming light, cutting optical loss. The lens is engineered and molded in-house at Bicom Optics, where optical design, precision mold making and injection molding are handled under one roof.

Technical Specifications

Models and Options

The catalogued model presented here is the Low Beam Inner Lens. Because each headlamp module has its own LED layout, the cavity count, array length and free-form profile are defined at the optical design stage for each project. Bicom Optics works on a customization model in which one product is developed around one focus point. Two-color and three-color parts can be produced in a single molding run, and thick-wall lenses up to 50 mm and light guides up to 1,300 mm are within the company manufacturing range.

Materials and Structure

The part combines a flat carrier body with a row of tapered cavities. Each cavity carries a free-form inner surface that collects light from the LED placed behind it and redirects it into the low beam pattern, so the optical function sits in the part geometry rather than in added secondary optics. Cavities are arranged side by side along the horizontal axis, which keeps the plate thin while still covering the full width of the lamp module.

Applications

• Low beam function in LED automotive headlamps
• Slim headlamp modules where installation depth is limited
• Headlamp assemblies built around a multi-LED layout
• Automotive lighting projects requiring even brightness across the beam

Customization

Optical design, precision injection mold design and mold manufacturing are core competencies at Bicom Optics, supported by a 50-engineer R&D team and 167 patents. Tooling relies on nanoscale CNC machining with positioning accuracy up to 10 nanometers and mold cavity precision adjustable within 5 microns. Dimensional verification uses CMM inspection and blue-light 3D scanning, and two-color or three-color molding can run in a single production cycle.
