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.

European style courtyard lights often use some European artistic elements from European countries, with abstract forms of expression. For example: Crown Courtyard Lamp. Modern courtyard lights often use modern artistic elements and employ minimalist techniques, such as spring sprout courtyard lights. Classical courtyard lamps often adopt Chinese classical elements and are used and modified, such as palace lamps. These three types of courtyard lights represent different styles and are derived by most manufacturers to cater to the design style of urban buildings.
