High-efficiency light sources engineered for linear cove lighting, backlight panels, custom fixtures, and hazardous outdoor environments.
Zhejiang Zionsville Lighting Co., Ltd. – Standardizing Quality, Precision Engineering, and Global OEM/ODM Procurement Since 2011.
Zhejiang Zionsville Lighting Co., Ltd. has established itself as a global benchmark in the design, engineering, and high-volume manufacturing of high-performance linear LED lighting systems. Founded in 2011, our organization operates at the intersection of solid-state physics, advanced optical science, and industrial-scale SMT (Surface Mount Technology) manufacturing. Specializing in high-density COB (Chip-on-Board) strips, silicone neon flex systems, addressable digital RGBW modules, and customized LED wall washers, we supply Fortune 500 lighting distributors, commercial contractors, and luxury architectural brands across the globe.
Our operational ethos is built on non-negotiable quality and strict engineering compliance. Operating under an ISO9001 certified quality management system, every product batch undergoes rigorous testing to guarantee thermal stability, chromaticity uniformity (McAdam Ellipse SDCM < 3), and long-term lumen maintenance (L80B10 > 50,000 hours). Our products are fully certified with international safety, electromagnetic, and environmental benchmarks, including ETL, TUV, CE, and RoHS, empowering seamless market entry across North America, Europe, the Middle East, and Asia-Pacific.
End-to-end control over component sourcing, automated SMT extrusion, optical testing, and post-sale engineering support.
Our R&D division consists of veteran optical, electronic, and mechanical engineers who deliver rapid custom prototyping within 72 hours. We introduce over 15 market-driven product series annually, ensuring our wholesale and distributor partners maintain a distinct technological edge.
We supply hundreds of specialized LED tape and neon flex variations across residential, commercial, and industrial domains. We offer complete OEM customization—including free laser printing of custom logos on PCB boards, private label packaging design, and bespoke master carton labeling without added surcharges.
Every product line undergoes stringent validation inside our advanced testing lab. Testing capabilities include integrating sphere spectroradiometry, thermal degradation aging, mechanical twist tests, extreme high/low-temperature thermal shock (-40°C to +80°C), IP68 immersion testing, and IES photometric reporting.
Our production floor is equipped with over 30 high-speed automated SMT lines, automatic silicone extrusion lines, and ultrasonic welding machinery. Automated optical inspection (AOI) ensures pinpoint solder precision, maximum production yield, and significantly reduced order lead times.
We do not rely on sampling metrics. Our Quality Assurance protocol dictates a 100% full inspection of all finished strips and fixtures prior to shipment, testing voltage draw, color consistency, dynamic dimming performance, and structural water resistance.
To support growing enterprises and urgent job-site requirements, we provide zero minimum order quantities (No MOQ) on stocked items, expedited sample dispatch within 24 hours, and back every shipment with a 5-year replacement warranty alongside 24/7 technical customer assistance.
An engineering analysis of COB Flip-Chip integration, silicone extrusion optics, and chromatic consistency metrics.
The global solid-state lighting (SSL) market has shifted dramatically from basic SMD (Surface Mount Device) packages—such as SMD 3528 and SMD 5050—toward integrated Chip-on-Board (COB) flip-chip architectures and micro-die silicone co-extrusion technology. Traditional SMD strips often suffer from visible "hotspots" or dotting, requiring deep aluminum extrusions with thick frosted diffusers that compromise overall luminous efficacy (lm/W).
"Information Gain Insight: COB Technology eliminates dark spots by packaging flip-chips directly onto a linear copper PCB, coated under a continuous phosphor silicone matrix. This achieves beam angles up to 180° and uniform dot-free linear light even in ultra-shallow profiles."
Modern commercial specifications increasingly reject standard Color Rendering Index (CRI Ra) metrics in favor of the comprehensive ANSI/IES TM-30-18 evaluation standard. While CRI Ra only measures color fidelity across 8 pastels (R1-R8), Zionsville’s Ra90 and Ra95 LED strips are calibrated to maintain high R9 values (>80 for deep red rendering) and balanced Fidelity (Rf > 90) and Gamut (Rg > 100) scores. This guarantees that illuminated retail merchandise, human skin tones, and architectural marble surfaces display rich, true-to-life vibrancy.
| Technology Parameter | Standard SMD Strip (e.g., 2835 / 5050) | High-Density COB Strip (FC-COB) | Silicone Neon Flex (Co-Extruded) |
|---|---|---|---|
| Luminous Uniformity | Visible LED dots; requires deep profile channel | 100% Dotless linear continuous beam | Homogeneous smooth neon glow effect |
| Beam Angle | 120 Degrees | 180 Degrees | 160 to 360 Degrees (3D Flexible) |
| Thermal Resistance (Rth) | Higher due to wire bonding & lead frames | Ultra-low (Direct Flip-Chip bonding) | Optimized thermal pathway through silicone |
| Minimum Bend Radius | Moderate (Risk of solder joint cracking) | High flexibility (No solder wire fatigue) | Extreme flexibility; lateral & vertical bends |
| IP Protection Rating | IP20 (Bare) / IP65 (Silicone glue spray) | IP20 to IP67 nano-coated / jacketed | IP67 / IP68 Dual-color silicone integrated extrusion |
Thermal management is the primary factor dictating LED lifespan and lumen degradation. Zionsville LED strip lights utilize multi-layer 2oz and 3oz rolled copper flexible printed circuits (FPC). Thicker copper layers reduce electrical resistance, minimize line-end voltage drop across long run lengths (up to 10m–15m single-feed runs), and accelerate heat dissipation away from the LED junction. This thermal optimization prevents thermal-induced color shift (chromaticity drift) over prolonged commercial usage.
Capitalizing on Zhejiang and Shenzhen industrial clusters to provide unprecedented speed, quality control, and cost performance.
China remains the undisputed epicenter of world-class optoelectronic manufacturing. Located strategically in Zhejiang, Zionsville Lighting leverages robust supply chain integration across raw materials—ranging from high-purity aluminum alloys, Cree/Epistar LED chips, Dow Corning silicone encapsulants, to high-grade 3M adhesive backings.
By centralizing the entire manufacturing value chain—from bare PCB layout design, high-speed SMT placement, silicone extrusion, and optical testing to custom box printing—Zionsville eliminates intermediary markup and reduces operational friction. Our strategic inventory management allows raw materials to be converted into finished, ETL-certified fixtures within days, giving global distributors a major lead time advantage over competitors.

Technical and procurement answers for lighting specifiers, OEM partners, and electrical wholesalers.
SMD (Surface Mount Device) strips use discrete packaged LED chips soldered at intervals along the PCB, which can produce visible light spots unless diffused. COB (Chip-on-Board) strips mount micro flip-chips directly onto the circuit board under a continuous phosphor silicone layer, delivering continuous dot-free linear light, wider 180° beam angles, and superior thermal dissipation.
We mitigate line-end voltage drop by utilizing heavy-duty 2oz and 3oz rolled pure copper FPC substrates, integrating constant-current IC driver chips onto the strip layout, and recommending 24V or 48V DC systems over 12V DC for commercial runs exceeding 5 to 10 meters.
Our manufacturing facility is ISO9001 certified. Our complete product lines hold ETL (for North American safety compliance), TUV, CE, and RoHS certifications, ensuring compliance with global electrical safety, fire retardancy, and hazardous substance standards.
