Courtyard lights are a type of outdoor lighting fixtures, usually referring to outdoor road lighting fixtures under 6 meters. Its main components are composed of: light source, lamps, lampposts, flanges, and foundation embedded parts. It has the characteristics of diversity, beauty and beautification and decoration environment, so it is also called landscape garden light. It is mainly used in outdoor lighting of urban slow lanes, narrow lanes, residential areas, tourist attractions, parks, squares and other public places, which can extend the time of people's outdoor activities and improve the safety of property. Here we briefly talk about the installation precautions of the garden light.
Install the courtyard lamp light source should use low-power high-color rendering high-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp and incandescent lamp. The insulation resistance value of the conductive part of each set of lamps to the ground should be greater than 2MΩ. The courtyard lights should be installed vertically, and the lamps such as column-type street lamps, floor-standing street lamps, and special garden lamps should be fixed and reliable with the foundation, and the anchor bolts and caps should be complete. Each set of lamp fuse box has a complete range of fuses, and the specifications are compatible with the lamp. The junction box or fuse box of the lamp and the waterproof seal of the box cover should be installed completely. The street lamps on the poles of overhead lines should be in the correct position, fixed and reliable, with complete fasteners and tightening. Each set of lamps should be equipped with fuse protection. Garden lights and pole-mounted street lights should be commissioned when they are automatically opened and closed according to the brightness of natural light, and the automatic power supply control device for lamps should be accurate.
Grounding of grounded courtyard lamps requires strict attention. The exposed conductors of metal posts and lamps should be connected to the PEN wire reliably. The grounding wire should be set alone, and the mainline should be arranged along the courtyard lights to form a ring network. The grounding mainline should be connected to the main line of the grounding device in no less than 2 places. Connect the branch line to the metal lamp post and the ground terminal of the lamp through the ground main line, and there is a mark. The grounding branch of the lamp cannot be connected in series with the lamp to prevent the displacement or replacement of individual lamps and cause the other lamps to lose their ground protection.
Electrical test run After the installation of the lamps and lanterns is completed, the electrical test is allowed only after passing the insulation test. After power-on, you should carefully check and patrol to check whether the control of the lamps is flexible and accurate; whether the switch corresponds to the control sequence of the lamps. If you find a problem, you should immediately power off, find out the cause and repair.
