Solar street lamps are powered by crystalline silicon solar cells, and maintenance-free valve-controlled sealed batteries (colloidal batteries) store electric energy. As a light source, ultra-bright LED lamp is controlled by intelligent charge-discharge controller and used to replace traditional street lamps for public power lighting. No cables need to be laid, no AC power supply is needed, and no electricity fee is generated; Adopt DC power supply and photosensitive control; It has the advantages of good stability, long service life, high luminous efficiency, simple installation and maintenance, high safety performance, energy saving, environmental protection, economy and practicality. Can be widely used in urban primary and secondary roads, residential areas, factories, tourist attractions, parking lots and other places.
Light pole structure
1, steel lamp post and bracket, plastic-sprayed surface, patented anti-theft screw connected to the battery panel. The solar panel bracket can rotate 3600 degrees, the lamp pole is tapered, and the control box is buried. The flange of the lamp pole is galvanized first, and then sprayed with plastic to prevent the rain from being wet and corroded in snowy days. The control box is equipped with patented anti-theft screws. The fixing screws of all parts are stainless steel, which are tightened with spring eyeliner, and no looseness is allowed. There are no cracks and scars on the lamp block and lamp post flange, and the screws are complete, and the bolt length can penetrate the lamp block flange.
2. Light pole strength: the wind pressure resistance of the whole fracture is 40kg/m2. Service life of lamp poles, battery panel brackets and lamps (except light sources): 12 years or more.
Lamp structure
1. The reflector of the lamp adopts high-purity anodized aluminum plate, and the oxide film is sealed, which has good reflection effect. The lampshade is made of PC material with good transparency, high temperature resistance and aging resistance, and the light transmittance is above 85%. Waterproof and dustproof grade IP65
2. The center line of the light source falls within the width of the road (calculated by X axis 120 degrees), and the elevation angles of all streets are consistent; Life of solar cell module: more than 25 years, life of storage battery: not less than 3-5 years, and foam insulation measures should be taken for storage battery; Controller life: 8 years; The service life of LED light source is more than 60,000 hours, and the light attenuation of light source is not higher than 1 5% within1year.
3. The solar energy system ensures that the energy storage and power supply time is not less than 3-5 consecutive rainy days, all equipment meets the technical requirements of relevant national standards, and there is a test report provided by a nationally recognized testing unit within the validity period.
