Why we need to use 60 degree lighting angle instead of 120 degree lighting angle for IR 850nm smd leds?
When using IR 850nm SMD LEDs, the beam angle (60° vs. 120°) makes a big difference in how the infrared energy is distributed:
🔹 1. Irradiance (Intensity per unit area)
60° beam angle:
Light is focused into a narrower cone.
Much higher irradiance (mW/cm²) at the target.
Better for longer-distance illumination (CCTV night vision, ANPR, security cameras, IR spotlights).
120° beam angle:
Light spreads out widely.
Lower irradiance per unit area.
Suitable only for close-range or wide-area applications (gesture recognition, short-range sensing).
🔹 2. Effective Distance
Narrower angles (60°) concentrate IR photons forward → illumination reaches further.
Wider angles (120°) spread photons → brightness per area decreases, so effective distance is much shorter.
🔹 3. System Efficiency
If your target (camera sensor, object) only needs IR in a specific field of view (FOV), using 120° wastes energy outside the camera's vision.
Example: If a camera FOV is ~60°, then a 120° LED wastes ~50%+ of emitted IR.
Using a 60° LED matches the optics, improving efficiency.
🔹 4. Heat & Power Management
To get the same intensity at distance with 120° LEDs, you'd need many more LEDs, increasing cost, PCB space, and heat load.
A 60° beam saves LED count and power for the same effective result.
✅ Summary:
We use 60° lighting angle instead of 120° for 850nm IR SMD LEDs when:
We need longer range illumination.
We want to match camera FOV.
We need higher irradiance per unit area without adding more LEDs.
⚡ If the application is close range and wide coverage (gesture sensing, facial recognition at <1m), then 120° makes sense. Otherwise, 60° (or even 30° with a lens) is preferred for CCTV, security, and industrial use.

60 Degree IR 850nm 940nm 2835 SMD LED Applications
60 Degree IR 850nm 940nm 2835 SMD LED Applications
CCTV / IP security cameras
60° matches most camera FOV, avoids wasted light.
Longer illumination distance (10–30m depending on power).
ANPR / LPR systems (Automatic Number Plate Recognition)
Stronger, more concentrated IR helps reflect from license plates.
Facial recognition / biometric systems
Mid-range use (1–5m), high intensity improves detection accuracy.
Night vision devices / hunting cameras
Good for mid- to long-range IR illumination.
Industrial machine vision
Detecting defects, barcodes, or objects with strong IR reflection.
