CRI と高効率の高い COB LED ストリップ: 市場の需要とサプライ チェーンの動向

Over the past decade, COB LEDストリップ have evolved from decorative lighting products into core light sources for professional applications. With growing demand from retail, commercial, medical, and architectural sectors, High CRI, High Efficacy, and Low SDCM have become fundamental performance benchmarks for COB LED strips. At the same time, a more mature supply chain, higher levels of manufacturing automation, and the adoption of new processes such as CSP, SCOB, and SOB have reshaped the market landscape. This article reviews the industry demand and supply chain evolution of COB LED strips from a historical perspective, analyzes the current market, explores regional distribution, and provides insights into future trends.

2015–2017: Early Development of COB LED Strips

Between 2015 and 2017, COB LED strips were in their early stage of development, with market applications focused primarily on decorative lighting, residential projects, and signage. Typical product specifications during this period included a CRI of around 80, efficacy of 90–100 lm/W, and SDCM ≤5. While sufficient for basic lighting and decorative purposes, these products fell short of professional lighting requirements in terms of color quality and consistency.

The main advantage of COB packaging was its ability to achieve high chip density on a single substrate, providing uniform illumination with reduced hotspots and graininess. Compared with conventional SMD LED strips, COB technology offered smoother light distribution and fewer visible light points (see comparison chart below).

2018–2020: Technology Upgrade and Quality Improvement

From 2018 to 2020, the COB LED strip industry entered a critical quality upgrade phase. As demand from retail, commercial, and architectural sectors increased, market standards shifted to High CRI (≥90), higher efficacy (110–120 lm/W), and lower SDCM (≤3). COB strips moved beyond decorative use and penetrated into supermarket shelves, hotel lighting, and office environments, where color consistency and reliability were essential.

During this stage, new packaging processes began to emerge:

CSP (Chip Scale Package): Reduced reliance on traditional lead frames, boosting efficiency and thermal performance.

SCOB (Small/Substrate COB): Enabled higher packing density and better uniformity, ideal for compact and flexible lighting.

SOB (Silicon on Board): Leveraged silicon substrates for superior thermal management and long-term reliability, piloted in select premium applications.

These innovations reshaped the supply chain: midstream packaging firms had to upgrade automation and precision testing, while downstream manufacturers gained access to more consistent and stable light sources. This period marked the transition from decorative lighting toward high-end commercial and professional applications, laying the foundation for the next wave of technological breakthroughs.

2021–2023: High-End Application Breakthroughs

Between 2021 and 2023, COB LED strips achieved a breakthrough in high-end applications. As the global lighting market shifted from “price-driven” to “quality-driven,” COB strips—featuring High CRI (≥95), higher efficacy (120–130 lm/W), and ultra-low SDCM (≤2)—became the preferred choice for retail, healthcare, museum, and premium architectural lighting.

Key demand drivers during this period included:

Retail and Commercial Spaces: Supermarkets, fashion stores, and jewelry retailers increasingly relied on high-CRI light sources to ensure true-to-life color rendering.

Medical and Laboratory Facilities: Required exceptional consistency and stability, making COB strips with Low SDCM and high reliability a natural fit.

Architectural and Landscape Lighting: Flexible COB LED strips gained traction due to their continuous illumination and no visible hotspots.

On the supply chain side, the combination of flexible substrates and automated packaging became central. Upstream manufacturers focused on chip efficiency and phosphor optimization, midstream packagers enhanced color uniformity testing, and downstream brands positioned COB strips not just as components but as part of system-level lighting solutions.

2024–2025: Current Market Landscape and Regional Distribution

By 2024–2025, COB LED strips have fully entered the performance range of 130–140 lm/W efficacy, CRI ≥95, and ultra-low SDCM (≤2), making them a mainstream high-end light source worldwide. The market shows several key characteristics:

Product Level: Flexible COBs, continuous long-length designs, and micro-pitch solutions are widely adopted, serving smart lighting, commercial display, and customized architectural applications.

Supply Chain Level: Upstream chip manufacturers are becoming more concentrated, midstream packagers are investing in automation and precision testing, while downstream brands focus on delivering system-level lighting solutions instead of standalone LED strips.

Market Level: Demand is shifting toward retail, healthcare, museums, and premium architecture, with clear regional differences.

Regional Market Distribution (2024–2025):

Asia (40–45%): China, Korea, and Japan lead the market, driven by commercial complexes and smart homes. China dominates flexible COB production and exports.
