Abstract
Description
Technical Field
[0001] The utility model relates to the field of street lamps, and more specifically, to a high-efficiency heat dissipation LED street lamp based on multiple LED light-emitting units. Background Art
[0002] Streetlights are typically installed along or in the center of a road to provide illumination at night or in low-light conditions. They can be categorized into various types based on their location and function. Road lights are primarily used to illuminate urban roads, highways, bridges, and other locations. Landscape lights are used in parks, plazas, scenic areas, and other places, not only to provide illumination but also to enhance aesthetics and decorative features.
[0003] The design of existing street lamps is relatively simple, lacking innovation and personalization, and it is difficult to integrate with the landscape styles of different environments (such as parks and residential areas). Since street lamps work for long periods of time and are in outdoor environments, their internal LED light sources and other electronic components are easily damaged by high temperatures, affecting their service life and lighting effects. The heat dissipation design of some street lamps is not reasonable, resulting in the inability to dissipate heat in a timely manner, exacerbating the aging and damage of the lamp holder. The installation and maintenance process of the lamp holders of some existing street lamps is relatively complicated, increasing maintenance costs and time costs. When the LED lighting unit of some street lamps is damaged, it is often necessary to remove the entire lamp holder or most of the components before replacement, which brings inconvenience to maintenance work.
