Bertin TY-1000-JT02 Fully-Protected Projection Crosswalk: Intelligent Light Language Redefining Intersection Safety
In today’s increasingly complex urban traffic environment, the right-of-way conflict between pedestrians and vehicles remains a core safety challenge. Traditional crosswalks rely on passive reflectors or fixed lighting, incapable of responding to real-time dynamics. The Bertin TY-1000-JT02 Fully-Protected Projection Crosswalk is an innovative active safety warning device designed precisely to solve this problem. It is far more than a simple projection lamp—it is an intelligent roadside interactive terminal that integrates “visual perception, logical decision-making, and optical intervention.”
Dual-Core Perception: From “Being Seen” to “Understanding Traffic”
The core technological breakthrough of the TY-1000-JT02 lies in its dual-camera heterogeneous recognition system. Unlike ordinary surveillance cameras, these two lenses perform distinct roles, constructing a three-dimensional perception front-end:
·
Pedestrian Recognition Camera: Equipped with a 5-megapixel sensor and 20x optical zoom, it runs dedicated pedestrian feature algorithms. It accurately captures pedestrian posture, movement direction, and speed across a wide field of view, effectively distinguishing between individuals, strollers, and small pets, significantly reducing false alarm rates.
·
·
Vehicle Recognition Camera: Simultaneously scans oncoming traffic in real time, identifying sedans, trucks, buses, and other vehicle types, while calculating approach speed and distance.
·
When signals from both channels cross-validate and determine that “a pedestrian is about to enter the crosswalk” and “a vehicle is approaching,” the system instantly triggers its core linkage mechanism—outputting a standard 5V high-low level switching signal. This seemingly simple electrical signal serves as the critical command linking “perception” and “action.”
Millisecond Optical Response: Projection That “Chases Danger”
Upon receiving the 5V trigger signal, the internal industrial-grade CPU immediately executes its pre-set decision program. Its actuator is a precision stepper motor closed-loop control system, rather than traditional solenoids or fixed shutters. The stepper driver enables the motor to complete precise angular rotation within milliseconds. The flange on the motor shaft drives a 4-position rotating pattern disk into rapid, accurate position.
This rotating pattern disk acts as the “ammunition depot” for content presentation. The four slots hold custom-made, high-transmittance glass pattern sheets treated with special coating processes. Depending on scenarios, these can be pre-loaded with warning messages such as “Slow Down,” “Vehicle Approaching,” or “Watch for Traffic,” and can even incorporate red/green crosswalk base patterns.
The optical system ensures perfect content projection: A 73° ultra-wide beam angle paired with a 6-element ultra-high-definition optical lens group keeps projected images sharp and clear at distances from 1 to 40 meters. With a color temperature of 8000-8500K and a CRI (Ra) >95, the device guarantees strong visual penetration in daylight, nighttime, rain, or fog (IP65-rated). Luminous flux dynamically adjusts between 26,000 and 58,000 lumens, preventing glare at night while remaining vivid during the day.
Scenario-Based Intelligence: More Than Brightness—It’s Adaptive
Unlike conventional projection lights, the TY-1000-JT02 features a control mode compatible with traffic signal systems, supporting adjustable pattern display durations from 0 to 255 seconds. This allows synchronization with traffic light phases—reinforcing “hurry through” or “wait for next cycle” during the final seconds of a green light. More intelligently, when the vehicle-recognition camera detects a large truck failing to slow down due to blind spots, the system can prioritize projecting a “Watch Out” pattern onto the ground directly ahead of the truck’s front side, achieving targeted “vehicle-to-pedestrian” warnings, while simultaneously showing “Oncoming Traffic” on the pedestrian side.
Robust Engineering, Built for Extreme Conditions
Every specification in the product datasheet is designed for 24/7 all-weather operation: The 1100W total power uses an IP68-rated waterproof power supply, with built-in surge protection (IEC61000-4 Level 4), over-voltage, over-current, leakage, moisture, and corrosion safeguards. The aluminum alloy housing operates stably between -30ºC and 50ºC. Despite compact dimensions of 34×30×36 cm, the unit weighs 25 kg—solid construction ensuring long-term reliability against outdoor vibration.
In summary, the TY-1000-JT02 establishes a closed-loop cycle of “sense-decide-project,” transforming abstract safety rules into dynamic light-based messages on the ground. With a precise beam of light, it draws a gentle boundary in the contest between vehicles and pedestrians—no longer just a cold traffic light or silent road marking, but an intelligent guardian that can “see” danger and “speak” warnings. It is the new standard for proactive crosswalk safety.
