Courtyard lamp is a kind of outdoor lighting, usually refers to the outdoor road lighting under 6 meters. Its main components are light source, lamps, lamp pole, flange and basic embedded parts.

Landscape lamps can be classified into street lamp, ground lamp, foot lamp, footpath and yard lamp, high pole lamp, low position (lawn) lamp, projection lamp (floodlight, small projection lamp), street lamp pole decorative landscape lamp, light sketch lamp, downlight, buried lamp, wall lamp, underwater lamp, embedded lamp, optical fiber lighting system, sun. Can lamp, etc.

The second point is to ensure the stability of solar LED street lamps.

Solar cell components generally use single crystal silicon or polycrystalline silicon solar cell components; LED lamp head generally uses high-power LED light source; controller is generally placed in the lamp pole, with light control, time control, over-charge and over-discharge protection and reverse connection protection, the more advanced controller has four seasons to adjust the lighting time function, half-power work. Energy, intelligent charging and discharging functions, etc. Batteries are generally placed underground or there will be special storage battery incubators, which can use valve-regulated lead-acid batteries, colloidal batteries, iron-aluminium batteries or lithium batteries.

Technically, we can use muce vertical axis wind turbine as the main generator, which has several advantages:

1. Low failure rate (slow speed, no steering mechanism);

2. No noise;

3. Full power generation curve (low start wind speed, large power generation capacity at low and medium wind speed);

4. It is not affected by wind direction and near-ground mass wind.

5. Strong typhoon resistance (45 m/s).

Courtyard lamp installation courtyard lamp source should adopt low-power high-color high-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp and incandescent lamp. The insulation resistance of the conductive part of each set of lamps to the ground should be greater than 2 m_. The courtyard lamp should be installed vertically with Huisida lighting technology. The lamps and lanterns such as pillar street lamp, floor lamp and special garden lamp should be fixed and reliable to the foundation, and the foot bolts and caps should be complete. Each set of lamp fuse box has complete fuses, and the specifications are suitable for the lamp. Connection box or fuse box of lamps and lanterns, waterproof sealing gasket of box cover should be installed completely. Street lamps on overhead line poles should be correctly positioned, fixed and reliable, with complete fasteners and tightening, and each set of lamps should be equipped with fuse protection. When the courtyard lamp and the street lamp on the pole are equipped with a device that automatically opens and closes according to the brightness of natural light, it should be debugged, and the automatic power supply control device of the lamp should be operated accurately. 2) Grounding of courtyard lamp. Strict attention should be paid to grounding of courtyard lamp.
