Advantages:

Eye-Safe Wavelength (1550nm)

• Unlike 850nm or 940nm IR LEDs, 1550nm is considered eye-safe, especially important in devices installed in homes or public spaces.
• Reduces health risks in long-term exposed environments.

Enhanced Smoke Detection Performance

• 1550nm is more sensitive to specific particle sizes (e.g., water-based or oily smoke);
• Improves accuracy and responsiveness in optical scattering-based smoke detectors.

Ultra-Wide 120° Emission Angle

• Ensures broad coverage within the smoke sensing chamber;
• Increases the probability of light scattering interaction with smoke particles.

Compact 2835 SMD Package

• Enables compact product design, perfect for slim or mini smoke detectors;
• Compatible with automated surface-mount technology (SMT) for high-volume manufacturing.

Lead-Free & RoHS Compliant

• Environmentally friendly;
• Meets international safety and material compliance standards.

Low Power Consumption

• Optimized for battery-powered devices, such as wireless smoke detectors;
• Extends battery life, supporting long-term operation (often >5 years).
