As the LED lighting industry upgrades towards higher efficiency and precision, substrate size, as a core factor influencing the compatibility and design freedom of CoB (Chip-on-Board) products, has always been a focus of industry attention. Lumileds, a leading global LED solutions provider, recently launched a new substrate size, further enriching its CoB product portfolio. This move not only breaks through the industry’s limitations in CoB substrate size compatibility but also expands the absolute design flexibility of Lumileds COB with its full-scenario product coverage, providing global lighting manufacturers with a more convenient and efficient selection solution, especially aligning with high-frequency Google search queries such as “Lumileds COB new substrate size” and “Lumileds COB substrate size compatibility.”

Lumileds’ newly launched substrate size is primarily used in its mature LUXEON Core and CX series, as well as the newly unveiled LUXEON CS CoB series. All three series offer substrate sizes that are fully compatible with industry-standard brackets and optics, allowing lighting manufacturers to directly integrate without adjusting existing production equipment or optical components, significantly reducing the cost of product upgrades and replacements. As a benchmark company in CoB technology, Lumileds is always market-demand oriented. The launch of this new substrate size is a precise response to the pain points of global lighting manufacturers-whether in mature markets like North America and Europe, or emerging markets like China and Southeast Asia, this upgrade enables rapid adaptation of Lumileds COB, further solidifying Lumileds COB’s technological leadership in the industry, while also catering to long-tail search queries such as “LUXEON CS CoBs compatibility” and “Lumileds COB compatible with industry-standard brackets.”

Although the LED industry has established comprehensive industry standards in areas such as chip specifications, luminous efficacy standards, and color rendering index, the lack of a unified standard for the substrate size of CoB products has long been a major bottleneck restricting industry development. For many years, companies worldwide producing CoB brackets and optical components have designed their products around the three substrate formats widely used by lighting manufacturers to adapt to mainstream market demands. This has led to lighting manufacturers often facing the problem of incompatible substrate sizes and the need to redesign systems when choosing CoB products from different brands, increasing R&D costs and extending product launch cycles. With the official launch of LUXEON CS CoBs, Lumileds has achieved a key breakthrough-it can now provide a full range of LUXEON CoBs products for every common substrate format, completely solving the industry pain point of substrate compatibility. This allows Lumileds COBs to be used in a wider range of applications, covering core global lighting markets such as the United States, Germany, China, and Indonesia, while also meeting precise search needs such as “Lumileds COB substrate format compatibility” and “LUXEON CS CoBs substrate size”.
 

“OEMs choose LUXEON CoBs for better luminous efficacy, color stability, and reliability, but they don’t want to redesign their systems,” said Noman Rangwala, Global Product Manager at Lumileds, explaining the motivation behind the new product launch. “Now, with the CS CoBs series, lighting manufacturers using many common substrate configurations can easily switch to LUXEON.” In fact, the core reason Lumileds COBs have become the preferred choice for global OEMs lies in their consistent balance between performance and convenience. They possess leading technological advantages while minimizing the application barriers for manufacturers. For example, in the EU market, the new Lumileds COB substrate size perfectly adapts to EU CE certification standards, meeting the compliance requirements of lighting manufacturers in European countries such as Germany and France. In the North American market, it adapts to North American UL lighting standards, aligning with local application specifications for supermarkets and industrial lighting. The implementation of the new substrate size further maximizes this advantage, simultaneously adapting to regions such as “Lumileds COB CE certification compatibility” and “LUXEON CS CoBs North American market application.”

As a new core member of Lumileds’ COB product matrix, LUXEON CS CoBs is not simply a substrate size upgrade, but rather a culmination of Lumileds’ years of accumulated advanced technologies. Its performance is highly consistent with the company’s mature Core and CX CoBs series, continuing Lumileds’ consistently high standards of COB performance. Positioned as a versatile, high-performance CoB product portfolio, this series is widely adaptable to various lighting applications, including track lights, downlights, spotlights, and high-bay lights, covering the needs of home, retail, industrial, and commercial sectors. For the Chinese retail lighting market, it precisely meets the display needs of domestic supermarkets and cosmetic stores. For Southeast Asian industrial lighting scenarios, such as factory lighting in Indonesia and Vietnam, the high cost-effectiveness of CS HE CoBs meets the cost control needs of local manufacturers, providing standardized, high-quality solutions for lighting manufacturers in different regions. It also aligns with long-tail keywords such as “Lumileds COB China retail application” and “LUXEON CS HE CoBs Southeast Asian industrial lighting.”

To address the differentiated needs of various application scenarios, the LUXEON CS CoBs series has been further refined and optimized: The CS Pro CoBs is specifically designed for retail lighting scenarios, precisely addressing the core need for “brighter and clearer” product displays. It features specialized spectral calibration and excellent color reproduction capabilities (supporting 80 and 90 CRI options), allowing the true colors of clothing, jewelry, and fresh produce to be accurately presented, effectively enhancing product appeal and helping retailers improve sales conversion rates-a feature particularly suitable for developed retail markets such as Europe, the US, and China. The CS HE CoBs, on the other hand, focuses on light-efficiency driven applications, achieving higher levels of performance through technological optimization (specifically, luminous efficacy exceeding 170 lm/W). It also boasts ultra-low thermal resistance, supporting smaller heat sinks, reducing the size and cost of lighting products while extending their lifespan. This makes it suitable for industrial lighting, outdoor lighting, and other scenarios with high requirements for luminous efficacy and reliability, such as North American industrial plants and European outdoor municipal lighting, while also meeting the requirements of “LUXEON CS Pro CoBs CRI value” and “Lumileds.” Long-tail search queries related to technical topics such as “COB luminous efficacy parameters” are common.

It’s worth noting that LUXEON CS CoBs are fully compatible with Lumileds’ optical, mechanical, and electrical ecosystem, coupled with its comprehensive technical support and after-sales service. Lumileds has dedicated technical support teams in North America, Europe, and China, providing localized services such as substrate adaptation guidance and technical consultation to lighting manufacturers, further reducing their design and maintenance costs. From a technical perspective, Lumileds COBs consistently innovate and iterate. Whether it’s the high flux density and small light-emitting surface (LES) advantages of the Core series, the flexible adaptability of the CX series, or the all-scenario coverage of the new CS series, all demonstrate Lumileds’ deep technical expertise in the CoB field, aligning with industry long-tail keywords such as “Lumileds COB technical advantages” and “LUXEON CoBs ecosystem.”

Currently, the LED lighting market is developing towards personalization, customization, and high efficiency, and lighting manufacturers are placing higher demands on the design flexibility, performance stability, and ease of application of CoB products.
