Product introduction: Traffic lights (also called traffic lights or traffic machine) are electronic devices used for road traffic management, used to indicate the control signals of pedestrians, vehicles, non-motor vehicles and other traffic modes. Traffic lights are often used in traffic management places such as urban roads, intersections, and highways, with the purpose of guiding traffic to proceed smoothly, safely and orderly.
Share:
Single-light traffic lights: including red, yellow and green traffic lights, usually used for simple traffic intersections.
Three-color traffic lights: commonly used in traffic management systems, including red, yellow and green lights, common in conventional road intersections.
Multi-function traffic lights: support the control of different traffic flows, such as setting up independent signal control systems for pedestrians, non-motor vehicles, buses, etc.
LED traffic lights: use LED lamp beads as light sources, with higher brightness and longer service life.
Intelligent traffic lights: combined with traffic flow monitoring systems, traffic management platforms, etc., to achieve dynamic adjustment of the working status of traffic lights and optimize traffic flow.
Countdown traffic lights: provide countdown display to tell traffic participants the remaining time for the signal light to switch, and enhance the reaction time of traffic participants.
Main functions of the product
Traffic flow control: According to the demand of traffic flow, adjust the switching cycle of traffic lights to ensure smooth road traffic.
Pedestrian/non-motor vehicle signal control: Equipped with pedestrian lights and non-motor vehicle lights to control the safe passage of pedestrians and non-motor vehicles.
Intelligent management: Support linkage with traffic monitoring systems, signal optimization systems, etc. to realize intelligent traffic scheduling.
Emergency vehicle priority: In emergency situations, provide green channel function to provide priority signal control for emergency vehicles such as emergency, fire, and police cars.
Night/bad weather mode: Automatically adjust the brightness of the signal light to adapt to night and weather conditions with low visibility.
Light source type:
LED lamp: high brightness, low energy consumption, long life. Commonly seen in modern signal machines, green, red, and yellow use LED lamp beads of different wavelengths.
Halogen lamp/incandescent lamp: Traditional light source with low energy efficiency has been gradually replaced by LED lamps.
Power: The power of each signal light is usually 10W to 30W, and the overall power depends on the specific lamp group and light source type.
Voltage: The standard working voltage is generally 220V alternating current (AC), and some also support 24V direct current (DC) power supply, especially emergency signal machines.
Signal light control method:
Timing control: Preset fixed time traffic light cycle.
Dynamic control: Adjust the signal cycle according to real-time traffic flow (intelligent transportation system).
Trigger control: Through vehicle detection and sensor trigger signal change, it is common at intersections.
Weather resistance:
Temperature range: -40°C to +70°C.
Protection level: IP54 to IP65, waterproof and dustproof, suitable for various climatic conditions.
Sight distance: The general sight distance of signal lights is 200 meters to 300 meters, suitable for different roads and environments.
Signal switching frequency: The switching time of general signal machines is 15 seconds to 120 seconds per cycle, which can be flexibly adjusted according to traffic needs.
Product structure design
Shell material: High-strength aluminum alloy or steel plate material is used, with good weather resistance, corrosion resistance and impact resistance.
Transparent mask: Usually use UV-resistant high-strength transparent plastic or glass mask to ensure the light transmission effect of the signal light.
Lighting configuration:
One-way signal light: Suitable for one-way traffic flow control.
Two-way or multi-directional signal light: Equipped with signal indications in multiple directions, suitable for intersections or complex traffic scenes.
Modular design: A variety of lighting modules can be combined as needed, and common combinations include red light, yellow light, green light, pedestrian light, etc.
Add sunshade: Adapt to strong sunlight environment and avoid direct sunlight that makes the signal light unrecognizable.
Traffic flow control: According to the demand of traffic flow, adjust the switching cycle of traffic lights to ensure smooth road traffic.
Pedestrian/non-motor vehicle signal control: Equipped with pedestrian lights and non-motor vehicle lights to control the safe passage of pedestrians and non-motor vehicles.
Intelligent management: Support linkage with traffic monitoring systems, signal optimization systems, etc. to realize intelligent traffic scheduling.
Emergency vehicle priority: In emergency situations, provide green channel
Urban intersections: Manage busy urban road intersections to ensure traffic safety and smoothness.
Expressways: Traffic lights can effectively manage traffic at toll stations, entrances and exits on expressways.
Tunnels and bridges: Traffic flow in tunnels and bridges is controlled by traffic lights to ensure safe passage.
Schools and hospitals: Traffic lights are set up in special areas such as schools and hospitals to ensure the safety of pedestrians and non-motor vehicles.
Large parking lots and entrances and exits: Suitable for entrance and exit control of large-scale parking lots, logistics parks, etc.
Anti-electromagnetic interference: Modern traffic lights generally have strong anti-electromagnetic interference capabilities to avoid signal interference from other equipment.
Fault alarm: When a traffic light fails, it usually automatically sends an alarm to the control center to facilitate timely repairs.
Daily maintenance: Regularly check the light source, line and control system of the signal light to ensure that the signal light is working properly. Clean the transparent mask to avoid dust accumulation that affects the visibility of the signal.
Energy-saving management: Use LED lamp beads and optimize the control system to achieve energy saving and long life.
Product precautions
Installation location: When installing the signal machine, it is necessary to ensure that the light source is unobstructed and avoid trees, buildings, etc. blocking the signal light sight distance.
Signal light coordination: In multiple signal light systems on urban roads, it is necessary to ensure that the time cycle of the signal lights is coordinated to avoid traffic jams.
Update and upgrade: With the development of technology, gradually upgrade traditional signal machines to intelligent and networked signal control systems to improve efficiency and safety.
