As we can see, in general, there is only one lamp pole for lighting in the place where we live. However, we often see some street lamp posts on both sides of the road. The top of some lamp posts will extend two arms and install two lamp caps to illuminate the roads on both sides. We call them double arm lamps. Street lamps can be divided into single arm lamp and double arm lamp according to their shapes. Today, high pole lamp manufacturers will introduce single arm lamp and double arm lamp to you respectively.
Single arm lamp is one of the most common road lamps. It has only one arm. The pole body is made of Q235 low-carbon high-quality steel by one-time bending and welding. The welding seam is smooth and smooth. After forming, it is treated by anti-corrosion, hot-dip galvanizing and plastic spraying. It has beautiful appearance, simple and smooth modeling characteristics. It is usually installed on both sides of the river channel, slope or wide road surface to illuminate the road conditions and induce safe travel The role of driving. Because of the different light sources, single arm street lamp can be divided into ordinary sodium lamp, energy-saving lamp, hernia single arm street lamp and LED single arm street lamp.
As a derivative lamp of single arm lamp, double arm lamp has two arms. The rod body is made of Q235 low-carbon high-quality steel by one-time bending and welding. The welding seam is smooth and smooth, and after forming, it is treated by anti-corrosion, hot-dip galvanizing and plastic spraying. The two arms have a certain degree of symmetry, which is more abundant than the single arm lamp, but they are not suitable for installation on narrow roads with single road conditions. They are generally installed on the green belt with multi lanes, taking into account the roads on both sides, or sections with special lighting requirements. Because of the different light sources, they are divided into ordinary sodium lamp, double arm street lamp, energy-saving lamp, hernia double arm street lamp and led double arm street lamp. The solar energy installation is also called double arm solar street lamp.
