Infrared power LED with variable beam angle for detection and illumination
The Sharlight SLE 35358CPC x3W aq is a 3W high-power infrared LED emitter with a peak wavelength of around 850 nm, intended for applications in IR lighting and detection.
The “x” in the type designation refers to the opening angle, which is available in 30°, 60°, and 90°, and thus determines the radiation profile.
- The 30° variant focuses the radiated power and is suitable for applications where range and directional sensitivity are important, such as targeted detection.
- The 60° version represents a compromise between intensity and dispersion.
- The 90° variant offers wide, uniform illumination for shorter distances, for example with IR camera support.
The ceramic housing has a thermal resistance of approximately 18 °C/W, which contributes to effective heat dissipation and stable behavior at higher power levels.
Electrically, the variants are identical, with a maximum forward current of 1000 mA (1200 mA pulse current) and a forward voltage of 1.3 to 2.0 V. The radiant flux lies between 700 and 800 mW, depending on the opening angle.
With an ESD resistance of up to 8 kV, the component is suitable for use in industrial environments.
