The core competitive advantage of this traffic signal is its certified explosion-proof design, which complies with GB 3836.1-2010 and GB 3836.2-2010 standards, making it suitable for use in Zone 1 and Zone 2 explosive gas environments. The high-penetration LED light source with a luminous intensity of over 15000cd delivers uniform, strong light output that can penetrate thick tunnel smoke, ensuring drivers can clearly identify signal changes from a distance of 600 meters. Unlike ordinary tunnel signals, it adopts a fully sealed structure with IP68 protection grade, which can be immersed in water up to 2 meters deep for a long time, adapting to flooded tunnel environments. The anti-corrosion cast aluminum alloy lamp body can resist chemical erosion from mine dust and petrochemical pollutants, with a service life of over 50,000 hours. Additionally, the built-in emergency backup power supply automatically activates during power outages, providing continuous signal guidance for over 2 hours, effectively avoiding traffic accidents and personnel trapped in tunnels.
The Explosion-proof High-luminance Tunnel Traffic Signal has a lamp body dimension of 650mm×650mm×200mm, with a total weight of 35kg. The light source adopts high-penetration 5050 SMD LEDs, with a color temperature of 6000K (daylight white) for green lights, 620nm (deep red) for red lights, and 590nm (amber) for yellow lights, ensuring visibility in tunnel environments. It operates within a temperature range of -40℃ to +65℃, adapting to extreme cold in alpine tunnels and high heat in deep mine roadways. The explosion-proof grade is Ex d IIB T4, which can be used in environments with flammable gases such as methane and propane. The power supply supports AC 220V (50/60Hz) with a DC 24V lithium battery backup, providing emergency operation for over 2 hours. The anti-vibration grade meets IP6X standards, resisting vibration from heavy trucks and mine machinery. The lamp body is coated with a 0.5mm thick epoxy anti-corrosion layer, effectively preventing rust and chemical erosion in harsh tunnel environments.
This product is mainly applicable to highway tunnels, especially long and extra-long tunnels with high traffic volume and frequent fog or smoke, as well as mine roadways where flammable gas and dust are present. It is also suitable for petrochemical plant internal roads, oil and gas pipeline construction sites, and other hazardous environments where explosion-proof safety requirements are high. In highway tunnels, it can be installed at tunnel entrances, exits, and interior sections to guide traffic flow, especially during emergency situations such as fires or power outages. In mine roadways, it provides safe signal guidance for mining vehicles and personnel, reducing the risk of collisions and explosions due to signal confusion. Additionally, it can be deployed in underwater tunnels or flood-prone tunnels, as its IP68 protection grade ensures stable operation even in flooded conditions. Tunnel construction companies, mine operators, and petrochemical enterprises are the core target customers, as it helps them meet strict safety regulations and improve operational safety in hazardous environments.
