COB Light Source Product Introduction

Our Chip-on-Board (COB) light sources are high-performance, compact surface light-emitting components, designed to deliver superior illumination quality for various lighting and backlighting applications. By integrating multiple LED chips directly onto a high-thermal-conductivity substrate, COB technology eliminates the limitations of traditional SMD light sources, offering exceptional brightness, uniformity, and reliability.
With advanced optical design and precise chip packaging, our COB light sources feature high luminous efficacy (120-150 lm/W), excellent color rendering (Ra≥80, optional Ra90-98 for high-end models), and stable color temperature (2700K-6500K, customizable dual-color or full-spectrum). The seamless light-emitting surface ensures no graininess, no dark spots, and low glare, providing soft and uniform light that protects eyesight and enhances visual comfort.
In terms of performance and durability, our COB products boast a low thermal resistance (<5℃/W) thanks to the direct chip-to-substrate connection, which enables efficient heat dissipation and reduces light degradation. With a long lifespan of 50,000+ hours (L70 at 80℃ junction temperature), they maintain stable performance even in harsh environments (-30℃ to +85℃ working temperature), ensuring no dead lamps or light spots during long-term use.
Available in a wide power range (3W-200W+), with customizable light-emitting surface (LES Φ3-32mm) and overall dimensions, our COB light sources are highly versatile. They are widely applied in backlight panels (large-size, high-brightness), downlights, spotlights, track lights, stage lights, film fill lights, automotive lighting, and industrial lighting, meeting the diverse needs of both commercial and industrial customers.
We support OEM/ODM customization, including substrate material selection (Al2O3 ceramic or high-thermal-conductivity aluminum substrate), power adjustment, color temperature customization, and dimming function design. All products comply with RoHS, CE, and FCC certifications, adhering to international quality and environmental standards. Choose our COB light sources for efficient, reliable, and high-quality illumination solutions.
