Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to an efficient heat dissipation LED street lamp. Background Art

[0002] Existing street lamps are mainly divided into street lamps for lighting and street lamps for landscape decoration. Street lamps for lighting are to ensure road safety and smooth passage of pedestrians and vehicles at night or when light is insufficient; street lamps for landscape decoration often pay more attention to aesthetics, thereby enhancing the visual effect of the city.

[0003] In some specific public places, such as squares and parks, there is a need for lighting, which is to provide sufficient lighting at night to ensure people's safety, and there is also a need for landscape. It is hoped that street lamps can become an important element in beautifying the environment and creating an atmosphere. However, it is difficult for existing street lamps to meet both needs. Even if some street lamps meet both needs, it is necessary to set up light-emitting units for lighting and landscape separately. This method not only increases the manufacturing cost and maintenance difficulty of street lamps, but may also affect the overall aesthetics due to the incoordination of the design between the light-emitting units. In addition, after the street lamp has been used for a period of time, the surface of the lamp head is easily contaminated with dust. If it is not cleaned regularly, it will affect the lighting effect. The existing lamp heads are more troublesome to clean. Summary of the invention
