[0002] Streetlights are typically installed along streets or highways to provide illumination. The lamp head generally consists of a housing and a light source and controller housed within it. A cover plate on the housing is usually used to secure the light source and controller together with screws inserted into corresponding mounting holes. When inspecting the light source and controller inside the streetlight, technicians need to remove the screws on the cover plate, then remove the cover plate to access the components. After inspection, the cover plate must be reattached to the housing using screws. This process is cumbersome, time-consuming, labor-intensive, and inefficient. Therefore, this invention proposes a streetlight with convenient maintenance to solve the aforementioned technical problems and improve maintenance efficiency. Summary of the Invention
