LED Array Chip on Board 1000 Lumen

A 1000-lumen LED Array Chip on Board (COB) is a compact, high-brightness LED module that integrates multiple LED chips directly onto a single substrate. COB technology provides higher light density, improved thermal performance, and more uniform illumination compared to traditional SMD LEDs.

What Does 1000 Lumens Mean?

Lumens measure the total amount of visible light emitted by a light source.

• 1000 lumens ≈ brightness of a traditional 75W incandescent bulb

• Suitable for:

• Downlights

• Spotlights

• Track lighting

• Flood lights

• Commercial lighting

• Horticulture lighting

Typical Specifications

How a COB LED Achieves 1000 Lumens

The lumen output depends on LED efficiency:

For example:

\text{Lumens}=\text{Power}\times\text{Efficacy}

A COB LED operating at 8W with 125 lm/W efficacy can produce approximately 1000 lumens.

Advantages of COB LED Arrays

Higher Brightness Density

Multiple LED dies are mounted closely together, creating a powerful and concentrated light source.

Better Thermal Management

The aluminum or copper substrate efficiently dissipates heat, improving lifespan and stability.

Uniform Light Output

COB LEDs produce a smooth light-emitting surface with minimal visible hotspots.

Compact Design

A single COB module can replace many individual SMD LEDs.
