High-Precision Infrared Sensors

Technological Breakthroughs in Infrared Sensing

Dual-element pyroelectric sensors: Uses high-performance sensor chips like LHI778 or RE200B, with built-in Fresnel lens arrays. Detection range: 10–15 meters (adjustable), detection angle: 120°, response time ≤0.5 seconds, false trigger rate ≤1%.

Multi-target tracking algorithm: Supports simultaneous recognition of pedestrians, vehicles, and non-motorized vehicles. AI algorithms distinguish target movement trajectories (speed, direction) to avoid false triggers caused by small animals or swaying leaves.

Smart Dimming Strategy

● Three-level brightness adjustment:

When people/vehicles pass: 100% brightness output (full power) to ensure safe passage.

When no people/vehicles are detected: Automatically switches to 20% brightness (energy-saving mode), reducing power by 80%.

In emergencies (e.g., fires): Forcibly switches to 100% brightness and continuous flashing alarm via external sensors or fire linkage signals.

Time threshold setting: Supports customizing brightness retention time (1–30 minutes) to avoid LED lifespan loss from frequent start-stop cycles.

● Environmental Adaptability Optimization

Temperature compensation algorithm: Built-in NTC thermistor monitors ambient temperature (-30°C~+60°C) in real time, dynamically adjusting sensor sensitivity to prevent detection deviations in high/low temperatures.

Anti-interference design: Uses 5.8GHz microwave filters to shield wireless signal interference (Wi-Fi, Bluetooth), ensuring detection stability.

High-Density LED Bead Array

● Technological Breakthroughs in LED Beads

Single bead power ≥1W, luminous efficacy ≥180lm/W: Adopts CREE XP-G3, OSRAM OSLON Square, or Lumileds LUXEON 3030 series beads with chip size ≥1mm² and current density ≤15A/cm². Brightness increased by 200% and luminous efficacy by 30% compared to traditional 0.5W beads.

Hexagonal close arrangement: Bead spacing ≤5mm, single module bead count ≥200 (for 600×300mm module), luminous flux density ≥1000lm/cm² to ensure uniform road illuminance.

● Optical Design and Light Distribution Optimization

Batwing lens technology: Uses PC material secondary optical lenses with beam angles of 90°×120°, ground illuminance uniformity U0≥0.45, and glare index (TI) ≤15 to avoid visual interference to drivers and pedestrians.

Multi-module splicing design: Supports 2–4 module splicing to cover road widths of 6–12 meters, suitable for single-side, double-side, and central symmetric lighting schemes.

● Reliability Verification

LM-80 light decay test: Continuous operation at 85°C for 6000 hours with light decay ≤8% (50% lower than traditional LED beads).

ESD anti-static test: Passed human body mode (HBM) 8000V and machine mode (MM) 200V electrostatic discharge tests to ensure bead stability in complex electromagnetic environments.

Multi-Scenario Installation Height Adaptability

Adjustable Installation Height Design

Telescopic arm length: Supports 3–6 meter retractable arms (aluminum alloy material, wall thickness ≥3mm), enabling quick height adjustment via locking bolts without additional tools.

Angle adjustment range: Lamp head supports 0°–30° pitch angle adjustment and ±15° horizontal rotation to adapt to different road slopes and lighting requirements.

Modular Structure

Split-type driver power supply: Separate design of driver power supply and lamp body, supporting external installation (protection level IP67) for easy heat dissipation and maintenance. Drive efficiency ≥95%, power factor ≥0.98.

Quick-detach bead module: Modules fixed by magnetic suction + buckle, single module weight ≤5kg, supporting 30-second quick replacement to reduce operation and maintenance costs.

Installation Scenario Adaptability

Urban main roads: Installation height 8–12 meters, spacing 30–40 meters, illuminance ≥20lx (meets CJJ 45-2015 standards).

Rural roads: Installation height 6–8 meters, spacing 40–50 meters, illuminance ≥10lx (energy-saving mode).

Parking lots and industrial parks: Installation height 4–6 meters, spacing 15–20 meters, supports parking space-level induction lighting (precise vehicle positioning).
