Explore our advanced technological systems, from precision CNC components to smart automotive illumination.
The global automotive and industrial illumination paradigm has entered a transformative era. Driven by rapid electrification, stringent environmental mandates, and the emergence of advanced driver-assistance systems (ADAS), simple illumination has evolved into highly engineered, solid-state lighting ecosystems. In this demanding landscape, Ningbo DERT Lighting Co., Ltd. has established itself as an industry-leading OEM/ODM manufacturer. Founded in 2012 and headquartered in Zhejiang Province, China, DERT operates a state-of-the-art 18,000-square-meter facility with over 320 skilled professionals. We specialize in precision engineering, micro-electronic assemblies (PCBA), custom lens injection molding, and finished system integration for global aftermarket and OEM distribution channels.
"Performance lighting solutions are no longer just components; they are critical thermal-optical assemblies where electronic stability directly correlates with safety, efficiency, and structural lifespan."
The automotive aftermarket and OEM supply chain are navigating a fundamental shift toward digital lighting. Traditional halogen and HID systems have been systematically replaced by ultra-efficient, solid-state LED systems and smart matrix setups. This macro shift is dictated by several factors:
We assemble high-durability PCBs, integrating advanced driver circuitry, smart microcontrollers, and thermal vias to guarantee system longevity.
Our custom optical lens molding and high-precision CNC machining processes ensure flawless sealing and perfect beam focus.
From DOT and SAE to E-Mark, CE, and FCC, we build products compliant with localized performance and electromagnetic safety norms.
Ningbo DERT Lighting provides a closed-loop development cycle for OEMs and aftermarket brands, mitigating supply chain complexities through in-house execution. Our capabilities encompass optical modeling, custom mold building, SMT assembly, and comprehensive mechanical design.
Optical Engineering: Utilizing simulation software like LightTools and LucidShape, our engineers calculate luminous intensity distribution curves, ensuring that light outputs prevent glare for oncoming drivers while providing superior peripheral illumination.
Thermal System Design: High-performance bulbs operating at 190W generate substantial localized thermal stress. We utilize copper substrate PCBs, vacuum heat pipes, and fluid-dynamic cooling fans combined with custom CNC-machined aluminum housings. This limits junction temperature to below 120°C, preserving diode integrity for over 50,000 operational hours.
Illumination needs differ by geography and industry segment. DERT’s versatile portfolio addresses distinct local and commercial configurations worldwide:

Detailed architectural, material, and logistical queries answered by DERT's chief engineering panel.
Our 190W assemblies integrate vacuum-sealed copper dual heat-pipes directly coupled to the LED substrate. This heat pipe transfers heat to a CNC-machined aviation-grade 6063 aluminum heatsink, cooled by a 12,000 RPM dual-ball bearing fan. Furthermore, we program intelligent thermal throttling into our custom driver PCBAs to dynamically balance output and heat in ambient environments above 50°C.
Every production batch undergoes a battery of quality verification tests. This includes 2-hour vibration testing to simulate rough terrain, ingress testing (IP67/IP69K), thermal shock testing (cycling between -40°C and 85°C), electromagnetic interference testing (EMI/EMC) for CAN-bus systems, and integrating-sphere photometric testing to verify lumen outputs and color rendering indices.
Yes. We possess an SMT production facility offering both rigid and rigid-flex PCB assembly solutions. Our technical engineering division handles design routing, schematic verification, prototyping, component sourcing (such as Automotive-grade Osram or Cree diodes), and programming of custom logic controllers to handle sweeping animations or DRL/turn signal logic.
Our OEM/ODM pipeline begins with CAD design and optical software mapping, followed by rapid 3D printing of housing prototypes. Once validated, we manufacture hard tooling for injection molding and extrusion, design the electrical drive components, and fabricate custom packaging to ensure your brand goes to market with high performance and zero compliance risk.
