Explore our collection of custom CNC machined automotive prototypes, LED optical assemblies, and precision tooling options manufactured to rigorous industry standards.
Established in 2012, Ningbo DERT Lighting Co., Ltd. has grown into a world-class manufacturing authority specializing in automotive lighting systems, high-intensity LED headlight assemblies, and advanced vehicle lighting solutions. Catering directly to global automotive aftermarket distributors and tier-1 OEM/ODM clients, we bridge the gap between initial design intent and robust mass production.
Operating from our highly integrated production facilities in Ningbo, Zhejiang Province—spanning approximately 18,000 square meters—we utilize modern optical engineering machinery and automated production pathways. Supported by over 320 skilled professionals across research & development, electronic control systems, structural engineering, optical simulation, and international logistics, DERT Lighting operates as a true system-level partner.
DERT Lighting focuses deeply on electronic control circuits, optical dispersion modeling, and advanced heat dissipation. By implementing copper MCPCB boards and high-conductivity aluminum alloys (AL6063), we ensure our lighting components operate with maximum lumen retention and thermal safety.
Precise ray tracing simulations optimize luminous flux and control glare to meet ECE and FMVSS 108 parameters.
Thermodynamic simulations predict internal junction temperatures, extending LED lifetimes beyond 50,000 operational hours.
Unveiling the production systems, prototyping methodologies, and strict quality verification structures required to excel as a global automotive exporter.
Before committing to multi-million dollar injection molds, tier-1 OEMs require perfect structural verification. We specialize in precision CNC milling and turning of optical-grade PMMA (Acrylic) and Polycarbonate (PC). Utilizing multi-axis CNC machines, we achieve micro-level tolerance clearances, allowing optical engineers to physically verify light patterns, light-guide efficiency, and mechanical fitment.
Scaling from rapid prototype to mass production demands high-durability steel tooling. Our injection molding services fabricate optical lenses, multi-color rear light covers (via multi-shot injection molding), and structural housings. We leverage specialized hot runner configurations and thermal cooling loops to avoid sink marks, internal stresses, and weld lines in highly clear transparent components.
To withstand weathering, gravel impact, and prolonged solar exposure, outer lenses undergo surface enhancements. We integrate inline UV-curing hard coating (HC) lines that provide anti-scratch properties and hydrophobic actions. In addition, our physical vapor deposition (PVD) vacuum metallization processes create reflective inner reflectors with high specular reflectance coefficients.
Unlike standard plastic housings, automotive light guide lenses must remain free from discoloration (yellowing) under intense UV exposure and heat. Standard PMMA options have high light transmittance (typically >92%) but are brittle, whereas Polycarbonate (PC) offers high impact resistance but requires advanced protective hard coatings to prevent environmental deterioration. A qualified OEM must be deeply proficient in handling both materials under cleanroom injection setups to eliminate airborne contamination that disrupts photometric patterns.
Leveraging China's leading automotive industrial cluster to deliver economic, logistical, and technical advantages to the international automotive market.
Our location in Ningbo puts us at the center of a dense industrial network. RAW materials, tooling components, high-precision electronic driver components, and custom hardware are sourced locally, dramatically compressing lead times for complicated builds.
By controlling product design, tooling fabrication, SMT (Surface Mount Technology) LED driver population, plastic injection, lens coating, assembly, and testing in-house, DERT minimizes external margins and eliminates supply-chain handoff friction.
Through lean manufacturing and semi-automated assembly configurations, we deliver significant cost improvements over Western European and North American alternatives, without sacrificing raw material grade or certification metrics.
Positioned minutes away from Ningbo-Zhoushan Port—one of the busiest deepwater cargo ports globally—we guarantee fast maritime shipping lanes, container consolidation services, and simplified export customs clearance.
From passenger vehicles to heavy-duty mining machinery, our custom assemblies are optimized for challenging physical environments.
Providing high-output LED plug-and-play bulbs (H4, H7, H11, 9006) with internal CANBUS decoders. These units solve compatibility challenges, preventing dashboard error codes and flickering issues in European and American passenger cars.
Engineering auxiliary spot/flood lights with IP68/IP69K sealing systems. These modules utilize die-cast aluminum heat sinks and high-vibration gaskets, surviving extreme dust, debris, and high-pressure washdowns on utility SUVs, heavy trucks, and agricultural equipment.
Integrating fiber optic starlight kits and smart micro-LED systems for premium commercial cabin styling. Using precise fiber optic light guides, we fabricate unique patterns, shooting stars, and multi-color interior accents controlled through advanced RF or Bluetooth interfaces.
As vehicle architectures transition to electric platforms and autonomous drive configurations, lighting undergoes a paradigm shift.
Traditional lighting is giving way to dynamic matrix systems. Matrix LEDs, controlled by onboard cameras, dim individual light fields to shield oncoming motorists from glare while keeping the surrounding area illuminated. We are refining our optical mold configurations to support multi-cavity lenses needed for clean beam separation.
Front grill structures and headlamp cavities are becoming the primary housings for radar, camera, and LiDAR setups. As an OEM manufacturer, we design housings that manage the thermal and optical properties of sensor windows, ensuring clarity and avoiding signal attenuation.
With the rise of Electric Vehicles (EVs), minimizing power draw is critical for range extension. Our engineering team designs optimized optical lenses paired with highly efficient CSP (Chip Scale Package) LED chips, providing high light output while lowering power demand.
Our factory operates to strict international quality standards, ensuring safety, reliability, and regulatory compliance.
Applying standard quality methodologies across product development, design testing, and manufacturing steps.
Goniophotometer testing guarantees luminous intensity distribution, ensuring compliance with ECE and DOT requirements.
Professional importers, automotive aftermarket distributors, and tier-1 OEM procurement divisions face unique supply-chain challenges. Sourcing automotive lighting is more complex than simple component acquisition; it requires strict adherence to regulatory standards, structural integrity, and logistical execution.
DERT Lighting structures its operations to support professional buyers: from initial engineering review (DFM - Design for Manufacturability) and rapid optical prototyping, to mold flow analysis and standard PPAP (Production Part Approval Process) Level 3 documentation. Our systems ensure traceability and consistency from pilot run to high-volume production.
