Mercedes-Benz W118 (CLA) Multibeam LED – Position/Indicator PCB (Dimensional Layout Model) · 模型 72679
This model represents a dimensional reference PCB used in the Multibeam LED headlamp system, specifically for the position light (parking light) and turn signal illumination. The model is not an electrical reverse-engineered schematic, but a geometrically accurate representation of: - PCB outline and mounting geometry - Connector position and orientation - LED placement zones and layout footprint It is intended for mechanical integration, packaging validation, and reverse engineering workflows, rather than electronic replication. --- Correct engineering terminology: - LED carrier PCB (layout model) - Light source board (positional reference) - Auxiliary lighting PCB (position/indicator) - Connectorized LED substrate (mechanical model) --- Functional role (real component): - Hosts SMD LEDs for: - Position light (DRL/parking light) - Turn signal (indicator) - Provides electrical interface via board-mounted connector - Ensures precise optical alignment relative to light guides and lenses --- Model scope (important clarification): This CAD model includes: - ✔️ PCB external contour and thickness approximation - ✔️ Mounting hole locations - ✔️ Connector housing and pin layout (approximate geometry) - ✔️ LED pad/placement zones (simplified representation) This model does NOT include: - ✖️ Electrical routing (tracks, vias, layers) - ✖️ Exact electronic components or BOM - ✖️ Functional circuit design --- Mechanical design features: - Rigid rectangular PCB substrate with mounting points - Integrated multi-pin connector footprint (through-hole style) - Defined LED emission zones for optical coupling - Layout optimized for compact integration inside headlamp housing --- Engineering application: - Reverse engineering of headlamp assemblies - CAD packaging and interference checks - Optical system alignment studies - Connector positioning and harness design - Basis for further full PCB reconstruction if needed --- Integration context: - Installed within headlamp housing assembly - Interfaces with: - Vehicle wiring harness (via connector) - Light guides / diffusers / optical elements - Works alongside main Multibeam modules and control electronics --- Model characteristics: - Clean and lightweight geometry - Optimized for assembly-level usage - Suitable for STEP/STL workflows - Designed for accurate spatial reference, not electrical simulation
