As we can see, we usually live in a place where there is only one lamp for lighting, but there are often several lamps on both sides of the road with two arms extending from the top, and two lamps are installed to illuminate the road on both sides respectively. We call them two-armed lamps. Street lamp according to the shape of the single-arm lamp and the difference between the two-arm lamp, today respectively introduce the single-arm lamp and the two-arm lamp.

Single arm lamp is one of the most common in the street, only a single arm, rod using high quality low carbon steel Q235 a bending welding, welding smooth and flat, anti-corrosion galvanized after forming and processing of injection forming beautiful appearance, concise and smooth shape characteristics, usually in the form of river cantilever lamp according to the light source can be divided into ordinary sodium cantilever bracket lamp and LED lamp, energy-saving lamp, hernia cantilever lamp, The installation of solar energy is also called a cantilever solar lamp.

The double arm lamp, as a derivative of the single arm lamp, has two arms. The rod body is bent and welded by Q235 low-carbon high-quality steel, and the welding is smooth and flat. After forming, it is processed by anti-corrosion hot dip galvanizing and injection forming. The two arms have a certain symmetry, and the shape is richer than that of the single arm lamp, but they are not suitable for installation on the narrow road surface of a single road. Generally, they are installed on the green belt of multiple roads, considering the roads on both sides and the roads with special lighting requirements. In addition, according to the different light sources, divided into ordinary sodium lamp double arm street lamp, energy-saving lamp double arm street lamp, hernia double arm street lamp and LED double arm street lamp, the installation of solar energy is also known as double arm solar street lamp.
