YEJIA's Light Guide Silicone Matrix Powers ADB Headlight Innovation

Industry Challenge: Upgrading Optical Components for Advanced ADB Headlights

With the rapid adoption of ADAS (Advanced Driver Assistance Systems) in high-end vehicles, the demand for Adaptive Driving Beam (ADB) headlights has surged. This trend has introduced three major challenges for optical components:

• 1. Precise adaptation to dynamic beam-shaping algorithms

• 2. Miniaturized design while maintaining high heat resistance

• 3. Complex optical structures that are difficult to manufacture

In early 2020, at the beginning of the new energy vehicle boom, a global Top 5 automotive lighting manufacturer approached YEJIA, seeking to replace traditional PC and PMMA optical lenses with a lightweight, high-performance light guide silicone matrix compatible with ADB systems. At that time, fewer than 3 domestic suppliers in China could meet the strict automotive-grade silicone optics production standards.

Technical Breakthrough: Triple Innovation in Silicone Light Guide Matrix Design

To meet the client's demand for a compact low-beam module—30% smaller than conventional designs—YEJIA's R&D team introduced three key innovations:

1. Microstructure Molding with LSR Precision

Using proprietary LSR (Liquid Silicone Rubber) mold technology, YEJIA achieved stable, defect-free production of 3 light guides (each 0.7mm × 19mm) within a 15mm-tall collimator. Tolerances were tightly controlled to within ±0.02mm, eliminating issues like bubbles and deformation.

2. Optimized Optical Performance

With a refractive index of 1.41, the silicone matrix achieved a high light transmittance of 92%. Its optical design enhanced the beam cut-off line clarity by 40%, perfectly aligning with matrix-type LED modules.

3. Automotive-Grade Reliability

The final product passed rigorous 5000-hour double-85 testing (85°C/85% RH) and exceeded ECE R112 performance standards for headlamp applications.

Scalable Production: Digital Quality Control System

To meet the micrometer-level inspection demands of the light guide matrix, YEJIA implemented a smart quality assurance process:

• 1. High-precision visual inspection: 50× magnification system auto-detects defects as small as 0.01mm

• 2. Real-time spectral analysis: Continuously monitors light transmittance

• 3. Tiered process control: From raw material curing to molding parameters, all stages are digitally traceable

This enabled the client to reduce overall headlamp module weight by 23% and guarantee customer's production schedule.

Competitive Advantage of Silicone Matrix

Compared to traditional optical materials like PC and PMMA, YEJIA's custom silicone optics offer:

1. Superior flexibility in complex geometries

2. High temperature and UV resistance

3. Longer service life under harsh conditions

4. Lighter weight without sacrificing optical clarity
