For road surveillance camera fill light products using xenon lamps, the typical specifications are as follows:

1. Power Specifications

• Common Power Range: 10W ~ 100W

  • Low Power (10W~30W): Suitable for short-distance illumination (e.g., license plate recognition at intersections).

  • Medium-High Power (50W~100W): Used for long-range or wide-area surveillance (e.g., highways, main roads).

  • Note: Power should match the camera's focal length and installation height to avoid overexposure or insufficient lighting.

2. Flash Parameters

• Color Temperature: 5000K~6000K (close to daylight for accurate color reproduction).

• Flash Duration: Typically 1ms~10ms (short bursts minimize glare for drivers while meeting capture requirements).

• Flash Frequency: Supports high-frequency triggering (e.g., 1~10 flashes per second), synchronized with the camera.

3. Key Performance Requirements

• Triggering Methods:

  • Light-controlled triggering (activates based on ambient light levels).

  • External sync triggering (synchronized with the camera shutter signal via RS-485/IO).

• Lifespan: ≥1 million flashes (high-quality xenon tubes can exceed 5 million flashes).

• Protection Rating: IP65 or higher (dustproof and waterproof for outdoor use).

4. Optical Design

• Beam Angle:

  • Narrow (10°~30°): Long-range focus (e.g., license plate recognition).

  • Wide (60°~120°): Covers large areas (e.g., intersection-wide monitoring).

• Filters: Optional IR or visible light cut-off filters for different camera sensors.

5. Typical Model Examples

• General Road Surveillance:

  • Power: 20W~50W, 5500K, flash duration ≤5ms.

  • Example: Hikvision/Dahua-compatible xenon fill lights.

• High-Speed Capture (e.g., ETC):

  • Power: 50W~100W, μs-level flash, high-frequency triggering.

6. Considerations

• Regulatory Compliance: Must meet standards like GB/T 14887-2011 (road signal lights) to avoid glare hazards.

• Efficiency & Heat Dissipation: High-power xenon lamps require heat dissipation (e.g., aluminum alloy housing).

• Alternative Solutions: For energy efficiency or longer lifespan, consider LED strobe lights (though xenon still excels in instant brightness).

For optimal performance, select the model based on specific surveillance conditions (e.g., mounting height, camera type, target distance) and consult us for tailored recommendations.
