CJ-401HSM-S 400mm LED Yellow Flashing Traffic Warning Light

This LED Yellow Flashing Traffic Warning Light is a large-format traffic safety warning device featuring a 400mm diameter illuminated face with a high-brightness yellow LED array, specifically designed for speed reduction guidance in construction zones and speed-restricted road sections.

Product Description

• Large-Format High-Intensity Display
The oversized 400mm luminous aperture significantly increases the visual duty cycle and presence of the signal. The high-contrast yellow LED strobe is engineered to penetrate intense sunlight, heavy rain, and thick fog, providing drivers with an extended warning distance even against complex backgrounds to ensure "Slow Down" commands are captured in time.

• Low-Power Architecture
System energy efficiency has been deeply optimized, with operational power consumption strictly maintained under 5W. The low-current driving solution effectively suppresses thermal accumulation at the light source, significantly slowing LED brightness decay and extending the overall operational lifecycle of the equipment.

• Durable Material Construction
The chassis is crafted from reinforced engineering plastics, achieving high structural rigidity while maintaining a lightweight profile. The PC/glass composite lens offers superior impact resistance, capable of withstanding long-term abrasion from road dust without developing micro-scratches, thereby preserving the purity and clarity of the signal light.

• Independent DC Power Supply
Equipped with a 12V DC input interface, providing exceptional system compatibility. This configuration is not only compatible with standard traffic control cabinets but can also be driven directly by vehicle power systems or portable energy storage units, greatly simplifying power access in temporary traffic control zones.

• Standardized Protection Rating
Meets the IP53 protection standard, with sealing optimized specifically for outdoor dust accumulation and precipitation. The internal circuit boards feature an anti-corrosion coating, ensuring electrical stability even in environments with drastic fluctuations in humidity.

• Compact & Efficient Installation
With product specifications of 530×493×150mm and a net weight of 7.5kg, the structural layout strikes an ideal balance between maximum visibility and ease of mounting. Whether installed on fixed utility poles or mobile tripod stands, the unit allows for rapid deployment and adjustment.

Installation & Compatibility
Low-Voltage DC Power Design: Supports a DC 12V input, making it suitable for integration into low-voltage traffic signal systems or independent power supply environments.

High-Visibility Yellow Flashing: Featuring a 400mm luminous diameter paired with high-brightness LEDs, the unit provides a stable flashing alert to warn of slow-speed zones or hazardous road sections.

Weather Resistance & Lightweight: The housing is constructed from plastic with a PC/Glass lens protecting the LED beads. With a net weight of approximately 7.5kg and an IP53 protection rating, it is built to withstand various outdoor weather conditions.

Simple Installation: Measuring 530 × 493 × 150mm, the unit can be mounted either horizontally or vertically on traffic poles or brackets, allowing for flexible deployment in traffic management.

Low Power Consumption: With a rated power of ≤ 5W, the LED flashing characteristics ensure long-term stable operation with minimal maintenance costs.

Applications
Slow-Speed or Congested Zone Alerts: Used in traffic control areas to prompt vehicles to decelerate and maintain a safe speed.

Construction & Temporary Management Zones: The yellow flashing signal alerts drivers to construction activities or temporary traffic arrangements ahead.

School & Community Safety Passages: Effectively guides vehicles to slow down, ensuring the safety of students and pedestrians in residential and educational areas.

Industrial Parks & Factory Roads: Ideal for highlighting slow-speed requirements, hazardous sections, or lane diversions to enhance internal traffic safety.
