Technical Specs & Certifications
The Chip on Board (COB) LED strip offered by Beauty (STC) Manufacturing Co., Ltd. is engineered for high performance and reliability, meeting the demanding needs of architectural, commercial, and high-end residential lighting applications. These COB strips integrate multiple LED chips directly onto a flexible circuit board, delivering a continuous, uniform light line with minimal visible hotspots—a hallmark of advanced COB technology.
In terms of efficiency, Beauty STC’s COB LED strips achieve luminous efficacy ranging from 100 to 120 lumens per watt, depending on color temperature and drive current. This high lumen-per-watt ratio ensures energy-efficient operation without compromising brightness, making the strips ideal for long-term installations where power consumption and thermal management are critical.
A key strength of these COB strips is their exceptional color rendering. All standard models feature a Color Rendering Index (CRI) greater than 90, with R9 values typically exceeding 50, ensuring vibrant, true-to-life color reproduction. This high CRI performance is achieved through the use of premium phosphor coatings and tightly binned LED chips, allowing for consistent color across multiple strips and batches. Optional versions with CRI >95 are available for applications requiring the highest color fidelity, such as retail display lighting and museum illumination.
Regarding environmental protection, Beauty STC offers COB LED strips in multiple IP ratings to suit diverse installation environments. The standard non-coated version is IP20, suitable for dry indoor use. For damp or outdoor applications, silicone-coated variants are available in IP65, providing protection against dust and low-pressure water jets. Fully encapsulated versions rated IP67 and IP68 are also offered, enabling submersion in water up to 1 meter for 30 minutes (IP67) or continuous submersion under specified conditions (IP68), making them ideal for outdoor cove lighting, signage, and landscape features.
Quality assurance is central to Beauty STC’s manufacturing process. Each COB LED strip undergoes rigorous testing for electrical performance, thermal stability, and color consistency. The use of high-purity gold bonding wires, thermally efficient substrates, and robust encapsulation materials ensures long operational life—typically rated at L70/B50 >50,000 hours under standard operating conditions. Additionally, the strips are RoHS compliant and undergo 100% aging tests prior to shipment, reflecting Beauty STC’s commitment to durability, safety, and superior optical performance in every product.
Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, Guangdong Province serves as a key production hub for advanced LED lighting solutions, including specialized chip-on-board (COB) LED strip products. The factory integrates modern surface-mount technology (SMT) capabilities with rigorous quality validation processes to support both standard and custom OEM requirements.
The SMT production lines feature multiple high-speed Fuji NXT III platforms configured for precision assembly of COB LED strips. These machines operate with 12-head placement systems capable of handling components down to 0201 metric size, achieving placement accuracy within ±0.025mm. Dual-lane configurations allow simultaneous processing of multiple strip designs, while nitrogen-reflow ovens ensure consistent solder joint integrity for thermally sensitive COB substrates. Automated optical inspection (AOI) stations are deployed post-reflow to validate component alignment and solder quality before proceeding to aging tests.
Aging validation for COB LED strips follows a stringent three-stage protocol. All strips undergo 72-hour continuous operational testing at 1.2 times their rated voltage within temperature-controlled chambers maintained at 50°C ambient. Thermal imaging cameras monitor hotspot formation across the COB array during this period, while integrated photometric sensors track lumen maintenance and chromaticity stability. Units failing to maintain >95% initial output or exhibiting color shift beyond MacAdam Step 3 are automatically rejected. Final verification includes 100% end-of-line checks for electrical safety compliance and mechanical durability.
For OEM partners requiring chip-on-board LED strip solutions, the Jiangmen facility provides comprehensive turnkey manufacturing services. This includes custom COB design support from substrate layout to thermal management optimization, with capabilities for flexible printed circuit (FPC) or rigid aluminum-backed configurations.
