As we have seen, there is usually only one street lamp for lighting, but there are often two street lamps on both sides of the road with two arms extending from the upper part, and two lamp holders are installed to illuminate the roads on both sides. We call them double-arm lamps. . According to the shape of street lamps, there are differences between single-arm lamps and double-arm lamps. Today, high-pole lamp manufacturers
introduce single-arm lamps and double-arm lamps respectively.
Single-arm lamp is the most common kind of street lamp. There is only one arm. The rod body is made of Q235 low-carbon high-quality steel by bending and welding at one time. The welding is smooth and flat. After forming, the appearance of anti-corrosion hot-dip galvanizing and injection molding is beautiful, and it has a simple and smooth appearance. Modeling features, usually river cantilever lamps are divided into ordinary sodium cantilever lamps, energy-saving lamps, hernia cantilever lamps and LED cantilever lamps according to the light source, and solar cantilever lamps are also called cantilever solar lamps.
The double-arm lamp is a derivative of the single-arm lamp. It has two arms. The rod body is made of Q235 low-carbon high-quality steel by bending and welding at one time. The welding is smooth and flat. After forming, it is processed by anticorrosive hot-dip galvanizing and injection molding. The double arms have a certain symmetry, and the shape is richer than the single-arm lights, but they are not suitable for installation on the narrow road surface of a single road. They are generally installed on the green belt of multiple roads. Consider roads on both sides and roads with special lighting requirements. In addition, according to the different light sources, it is divided into ordinary sodium lamp double-arm street light, energy-saving lamp double-arm street light, hernia double-arm street light and LED double-arm street light. The installation of solar energy is also called double-arm solar street light.
