Description

3535 Bi-Color LEDs: White + Infrared (IR)

Overview

The 3535 Bi-Color LED integrates a high-efficiency white LED and a monochromatic infrared (IR) emitter in a single surface-mount package (3.5 mm × 3.5 mm).
Designed for intelligent lighting and surveillance systems, it enables seamless transition between visible illumination and covert night-vision support.
Each channel is electrically independent, allowing precise control over white light and IR output.

💡 Application Note:
Ideal for day/night adaptive lighting systems such as:
• Security cameras with auto-switching visible/IR illumination
• Smart streetlights with human-visible lighting + IR motion sensing
• Machine vision systems requiring multi-spectral illuminationNote: White and IR channels must be driven independently using a dual-channel constant-current driver.
