Yard lamp, a kind of outdoor lighting, is a kind of outdoor lighting with unique shape and mainly ornamental. It should be used in urban roads, residential roads, industrial parks, landscape lighting, tourist attractions, parks and courtyards, and greening. Strip, square lighting and lighting and other decorations. It has the functions of lighting, beautiful and beautifying the environment. With the development of the city and the increasing requirements of people for residential design, courtyard lights have gradually entered our field of vision and become an indispensable lighting tool in urban construction. Under the new form of energy saving and consumption reduction becoming the trend of the times, in addition to good lighting functions, courtyard lamps must have good decoration and energy-saving functions are also important indicators to measure the level of lamp manufacturing. The survey found that many urban landscape lighting projects currently have high illuminance and large scale, but can only achieve simple opening and closing in the control mode, and cannot achieve unified management and intelligent operation. The lighting pattern remains unchanged, which results in electrical energy. A large amount of waste has increased the power shortage. In order to not only play the role of landscape lighting to beautify the city, but also not waste electric energy and human resources, we should integrate the needs of various landscape lighting and formulate a reasonable control mode. Various control modes Urban landscape lighting can be roughly divided into: building (structure) decorative lighting, square lighting, municipal public facilities decorative lighting, and green lighting. Buildings (structures) can be divided into two categories: public and commercial according to their nature. Therefore, the control mode cannot be generalized, and a variety of control methods should be used to meet the overall effect. One, open all year round is suitable for urban landmarks, key buildings in the city center, landscape passages and other landscape lighting projects. Second, open on weekends Landscape lighting projects such as residential buildings, government agencies and public places such as squares, greening, bridges, etc., are of less importance and do not need to be turned on throughout the year. In order to save power consumption for landscape lighting, it is possible to consider reducing the number of days that are turned on throughout the year. 3. Partially opened similar to the business buildings such as hotels, commercial buildings, shopping centers, etc., because of their night business needs, opening on weekends is not feasible. The landscape lighting facilities of each project can be classified. In weekday mode, some of the more powerful facilities such as: facade floodlights, top floodlights, etc. can be turned off.
