Red yellow green traffic signals are used outdoor for long periods of time and are directly exposed to wind, sand, rain, snow, dust and large temperature variations between day and night. IP54 waterproof and dustproof is standard configuration, for stable operation and long service life. IP54 rating of LED traffic lamps means they are completely protected against dust and rain splashes from all directions, so they are suitable for most city roads, country crossroads and park entrances. Qixiang details the manufacturer’s standardized production process of red green amber traffic lights, which comprehensively ensures the outdoor protection performance of the signal lights.
Raw material selection is fundamental to protective performance. The lamp housing is made of high strength flame retardant PC material or die-cast aluminum, and is coated with UV resistant and anti-aging coatings. This results in a hard, non-deformable material that resists outdoor weathering and dust abrasion. The optical lens is made of high transmittance PC material, which is coated with anti-fogging and anti-yellowing, balancing light transmission and sealing protection. All sealing elements are manufactured from high and low temperature resistant silicone rubber to guarantee no cracking at low temperature and no deformation at high temperature, and the elasticity remains stable even after long-term usage to prevent seal failure.
Refined assembly and better protection processes lead to improved product stability. Production is done in a cleanroom environment to avoid dust residue left inside the lamp body during assembly. All fasteners are stainless steel and torqued to standard to prevent screw loosening and seal movement due to long term outdoor vibration. Secondary adhesive is used to reinforce lamp body interfaces and corner gaps for an optimal sealed closed-loop structure, suitable for outdoor conditions like wind, sand and rain.
Finished red yellow green traffic signals are fully tested according to IP54 before leaving the factory. These include sand and dust spray tests and comprehensive rain splash simulation tests to identify and eliminate potential leaks and dust ingress. Defective red green amber traffic lights are reworked. The stability of the protective structure is also checked by means of high and low temperature aging tests and vibration tests, so that each device meets the standards of long-term, maintenance-free and stable operation in outdoor conditions.
Qixiang red yellow green traffic signals with IP54 protection have a thickened PC/cast aluminum shell that is weather-resistant and has a double-layer silicone seal to protect against rain and dust from all directions, as well as to resist erosion from rain, snow, and sand. The lens has been treated with anti-yellowing and anti-fogging treatment for even light transmission. An LED light source has higher stability and lower energy consumption. The whole unit has been tested many times, such as with sandblasting, high- and low-temperature aging and vibration testing. Stainless steel fasteners are rust resistant so are less likely to allow water in to cause malfunctions when used outside for long periods of time. Support customizable size, voltage, and appearance. Before shipment, we carry out strict quality control to ensure durability and peace of mind. Bulk orders of red green amber traffic lights are applicable for many scenarios such as urban roads, rural intersections, and industrial parks with high cost-effectiveness.
