Traffic lights are silent "traffic policemen." The red light is a stop signal, and the green light is a traffic signal. At the crossroads, cars from several directions are gathered here. Some of them must go straight and some must make turns. Whoever wants to go first is to follow the command of the traffic lights. The red light is on. It is prohibited to go straight or make a left turn. The vehicle is allowed to make a right turn without disturbing pedestrians and vehicles. The green light is on, allowing the vehicle to go straight or make a turn. The yellow light is on and stops at the intersection stop line or pedestrian crosswalk. When the yellow light is flashing, warn the vehicle to pay attention to safety.
The traffic signal uses light-emitting diode (LED) as the light source signal lamp. Under the rated voltage of AC 220V, the power of a single light-emitting unit does not exceed 25W.
The rated working voltage of the traffic signal power supply is: AC220V, 50Hz; when the power supply voltage fluctuates in the range of AC220V±44V, 50Hz±2Hz, it can work normally.
Traffic lights technical data and related requirements:
Luminous intensity is: red, yellow led diode luminous intensity is greater than 600mcd, the use of ultra-high brightness four-element led as light source, in line with the international industry two anti-static (esd-2000) standards. The luminous intensity of the green LED tube is greater than 6000mcd, and it is encapsulated with the US CREE chip. The light color complies with the provisions of GBI14887. Color requirements: red 625nm, yellow 590nm, green 505nm.
Traffic lights use four-lamp combination. The red, yellow, and green lights are full-screen lights and digital displays. Full plate arrangement is intensive. Led life of not less than 80,000 hours, led lights visible distance of not less than 1,000 meters. Single lamp power consumption is less than 10 watts, working voltage AC180-260, no color change. The PCD board uses a rigid printed circuit board made of a flame-retardant material and is tin-plated. The coating is not oxidized and the thickness is more than 1.8mm. Each lead of the light emitting unit adopts wires conforming to the national electrician standard, and the wire diameter is not less than 1.5mm. All vital components were subjected to an aging test and electric parameters and light parameters were tested separately.
Traffic signal lighting entrance has reliable insulation, waterproof and dustproof measures to ensure that the road traffic lights are not lower than the required IP53 protection level.
Shell structure, beautiful appearance, strict sealing, moisture, dust.
1. Traffic lights must comply with GB14887-2003 (Technical Requirements and Test Methods for Road Traffic Signals).
2. The technical indicators of traffic signals are detected by the Ministry of Public Security's Product Quality Supervision and Inspection Center and have corresponding inspection reports.
3, traffic lights lens made of high transmittance polycarbonate, 10 years of service life.
4. Silicone rubber material is used for all seals in traffic lights. During the 10-year trial period, aging and hardening do not occur at high and low temperatures.
5, working voltage: AC220V ± 44V 50HZ ± 2, power? 12W.
6. Wavelength: Red 625nm Yellow 590nm Green 505nm.
7, the ambient humidity: -40 °C -70 °C, relative humidity is 93%.
8, can be visual angle? 35 degrees visual distance? 1000m.
CA Temporary Fence Introduction:
Temporary Fence is also called
Construction Fence,Removable Fence and Portable Fence. This type was
very popular in Canada, the United States, and some other America
countries.
It is quick to be set up and easy to move and is ideal for restricting
access or containing a site and is commonly seen at construction sites,
public events, as a dog run, or anywhere crowd control is important.
It offers the benefits of affordability and flexibility.
