One Screen Three Color Signal Light Suppliers

In extremely cold environments, traffic lights often face severe tests, especially in areas with sudden drops in temperature and ice and snow in winter. Traditional traffic lights may experience brightness attenuation, bulb damage, shell cracking or inability to start at extremely low temperatures, which not only affects the normal operation of traffic management, but also may bring safety hazards. The design of the one-screen three-color traffic light of Yangzhou Shangyuan Intelligent Transportation Technology Co., Ltd. fully considers the challenges of extremely cold climates, and adopts high-strength antifreeze materials and advanced thermal management systems to ensure that traffic lights can work normally in low temperature environments.

The LED light source of the traffic lights of Yangzhou Shangyuan Intelligent Transportation Technology Co., Ltd. has good low-temperature starting performance, is not easily affected by cold climates and has brightness attenuation or failure, and can still maintain good luminous effects at low temperatures of -40℃. This is crucial for cold areas in the north, especially areas with long-term low temperatures or heavy snow. In these areas, the stable operation of traffic lights is directly related to traffic safety. A three-color traffic light on one screen can still maintain high brightness and accurate color presentation in cold environments, ensuring that traffic instructions are clearly visible, thereby reducing traffic accidents caused by low visibility or traffic light failures.
In addition, the design of the traffic lights of Yangzhou Shangyuan Intelligent Transportation Technology Co., Ltd. also takes into account the influence of the external environment, and adopts a special waterproof, dustproof and frost-proof structure and sealing design to effectively prevent the accumulation and penetration of snow, frost and ice, and avoid signal light display problems caused by ice and snow coverage. Especially in extremely cold winters, a three-color traffic light on one screen can resist freezing and continue to provide accurate traffic signal instructions, providing safe and reliable traffic guarantees for drivers and pedestrians.

Compared with cold regions, the high temperature environment in tropical and subtropical regions also poses a challenge to traffic lights that cannot be ignored. Long-term high temperature exposure will not only accelerate equipment aging, but may also cause circuit failures, shell deformation and even fire hazards. Traditional signal lights are prone to problems such as damage to electronic components and reduced light source brightness in high temperature environments, affecting the normal operation of the traffic management system.

The single-screen three-color signal light of Yangzhou Shangyuan Intelligent Transportation Technology Co., Ltd. fully considered this point when designing, using high-temperature resistant materials and intelligent heat dissipation systems to ensure that the equipment can maintain stable performance under high temperature conditions. The operating temperature range of the signal light can cope with extreme high temperature environments up to +70°C, greatly improving its reliability and durability in hot summer. Even in hot summer weather, after long-term sunlight exposure, the signal light can still maintain efficient and stable working conditions without overheating, failure or reduced brightness.
Such a design makes the single-screen three-color signal light very suitable for traffic signal facilities in tropical areas or high temperature climate conditions. For example, in the south or coastal cities, signal lights must not only be resistant to high temperatures, but also face complex environmental factors such as frequent heavy rain, humidity, and salt spray. The one-screen three-color signal light effectively improves the service life and reliability of the signal light through its high-temperature resistant and corrosion-resistant shell design, reduces the frequency of equipment maintenance, and reduces traffic management costs.
The shell design of the signal light has undergone precise thermal analysis, and the surface of the shell uses a material with excellent heat dissipation performance. Through reasonable structural layout and material selection, the heat generated inside is effectively dispersed and discharged to avoid high temperature accumulation and affect the performance of electronic components. This design allows the signal light to work stably in an environment of up to +70℃ and extends the service life of the equipment.
In addition, the thermal expansion coefficient of the shell material is precisely controlled to ensure that the signal light will not deform or damage in an environment with a large temperature difference. Whether it is a cold winter or a hot summer, the shell material can adapt to the rapid changes in temperature, avoiding problems such as shell cracking and deformation caused by sudden temperature rise and fall.

In a high temperature environment, the internal circuit and LED light source of the signal light will generate heat, and long-term high temperature may affect the performance and life of the equipment. To solve this problem, Yangzhou Shangyuan Intelligent Transportation Technology Co., Ltd. adopts an intelligent heat dissipation system and thermal expansion control design to ensure that the signal light can still maintain stable operation in a high temperature environment.
