Street lamp is an important facility for urban road lighting, and its voltage is generally determined by the municipal department according to the actual situation and needs. In most countries and regions, the street lamp voltage is generally 220V, because 220V is a common household voltage, which is convenient for the connection and power supply of household power systems.
However, in some special cases, the street lamp voltage may be different. For example, the street lamp voltage in some European countries may be 230V, because the voltage standard of household electricity system in these countries is 230 V, and the street lamp voltage in the United States and Canada is generally 120V, because the voltage standard of household electricity system in these countries is120 V.
In addition, the street lamp voltage in some special places may be different. For example, in some highways or tunnels, in order to provide stronger lighting effect, the street lamp voltage may be increased to 240V or higher. In some remote areas or special environments, in order to meet the power supply demand of street lamps, renewable energy such as solar energy or wind energy may be used for power supply, and the voltage of these street lamps may be different.
In short, the street lamp voltage is generally 220V, but it will be different according to different countries, regions and special needs. No matter what kind of voltage, it is to ensure the normal work of street lamps and provide good lighting effect.
