LED, as a new type of semiconductor light source, has the following advantages compared to traditional light sources: long lifespan, emitting time up to 100000 hours; The startup time is short, and the response time is only a few tens of nanoseconds; Solid structure, as a solid all solid structure, capable of withstanding strong oscillations and impacts; High luminous efficiency and low energy consumption, making it an energy-saving light source; The luminous body is close to a point light source, and the radiation model of the light source is simple, which is conducive to lamp design; The directionality of light emission is very strong, and there is no need to use a reflector to control the direction of light irradiation. It can be made into a thin lamp, suitable for situations where there is not too much installation space.

Courtyard lights have the characteristics of diversity, aesthetics, beautification, and decoration of the environment, so they are also called landscape courtyard lights. Mainly used for outdoor lighting in urban slow lanes, narrow lanes, residential areas, tourist attractions, parks, squares, and other public places, it can prolong people's outdoor activities and improve property safety.
