Tunable LED array ACULED®

chipprinted circuit board-mountedhigh-brightness

Overview
The ACULED platform is a chip‑on‑board (COB) LED package containing four individually addressable chips designed for medical lighting applications requiring tunable white light and precise spectral control. It supports standard and custom wavelengths across UV, visible and near‑infrared ranges while delivering high color rendering for clinical and surgical environments.

Design and Configuration
The ACULED allows system designers to configure a four‑chip arrangement from standard or custom chip types to meet specific application needs.

• Chip options: white chips, UV, IR, and sensor chips
• Available wavelength range: 254 nm to 1,200 nm

Features

• Tunable White Lighting — Four independently addressable chips enable CCT tuning from 2,700 K to 6,500 K while maintaining CRI and R9 performance required for surgical and dental lighting.
• Superior Color Mixing — Close chip placement supports uniform color mixing at the illumination surface; optical designers can blend outputs of each chip to achieve the required appearance for clinical tasks.
• High Output Capability — Four chips with drive current capability up to 1,000 mA provide high luminous output from a single package, enabling simplified optical systems and reduced component count.

Compliance and Emission
ACULED packages exhibit near‑Lambertian emission characteristics and are RoHS compliant, facilitating integration into regulated medical luminaires.
