Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lighting, in particular to a combined street lamp. Background Art
[0002] In the prior art, when street lamps are installed on the ground, the connection between the bottom of the lamp pole and the ground is exposed and prone to rust. The main technical difficulties are caused by the following specific causes: First, when the connection between the bottom of the lamp pole and the ground is exposed to the air, it reacts with oxygen to form oxides, which leads to oxidation corrosion on the metal surface. Especially in a humid environment, the oxygen in the water vapor will accelerate the oxidation reaction of the metal, making the connection more susceptible to corrosion; Second, in the grounding system, since the underground soil contains various ions, when the connection between the bottom of the lamp pole and the ground is at different potentials, an electrochemical cell will be formed, generating current, leading to electrochemical corrosion on the metal surface. This corrosion will aggravate the damage to the connection and make it more susceptible to rust; Third, during use, the connection between the bottom of the lamp pole and the ground may be affected by external forces, such as wind, rain, vehicle collision, etc., resulting in wear of the coating on the surface of the connection or damage to the metal surface, making the metal exposed to the air more susceptible to corrosion.
[0003] In summary, the technical problem of the easy rust of the connection part between the bottom of the lamp pole and the ground is caused by the combined action of multiple factors such as oxidation corrosion, electrochemical corrosion, mechanical wear, etc. In order to solve this problem, the inventor proposed a combined street lamp.
