What is Solar underground light?

Letect-Solar-underground1-light
Brief introduction
Solar underground light ether sunlight for energy, mainly by charging during the day, night use, without complex and expensive pipeline laying, the layout can be adjusted lighting, security, clean energy, charge, and on / off process using intelligent control, automatic light control switch , without manual operation, for stability by saving electricity, maintenance-free.
Buried lights generally less power, typical lamp type is circular and square.
Produced using silicon or polycrystalline silicon solar panels, LED lamp beads, batteries, and other components. Style shape colorful, colorful, chic and elegant, can courtyards, parks, playgrounds and other dress picturesque. Each time the product is fully electrically continuous illumination 4-5 days, working 8-10 hours a day, it can also be designed in accordance with the special requirements of users.

Product Specifications
* Solar Panel: crystal silicon 15-80WP (load profile
* Controller: solar lighting dedicated controller, light control + control
* Storage battery: fully enclosed maintenance-free lead-acid batteries
* Rainy day guarantee: can work four to five rainy days (there are differences between different regions / season) (according to requirements)
This product without laying underground cables without paying lighting electricity, the key component of solar panels Solar underground light employed, solar DC lamp intelligent controller, maintenance-free batteries, LED lights beads have been NDRC / GEF / World Bank PV certified product. Mainly applied to lighting lighting urban roads, residential square, industrial parks, tourist attractions, parks and green belts and other places.

working principle
Solar panels to achieve photoelectric conversion by the light, produce direct current, and then to charge the battery through the controller, the battery stores electrical energy. At night, the battery through the controller automatically discharge and start working, without human management.
Scope editor
Urban roads, residential areas, parks, tourist attractions, squares and other lighting and decoration. Users may also need to transform the city said local electric lighting system into a solar lighting system.

Solar underground light advantage
1. Long life light-emitting semiconductor chip, no filament, no glass bulb, afraid of shock, not broken, the service life of up to fifty thousand hours (incandescent life of only one thousand hours, the general energy-saving lamp life of only eight thousand hour)
2. Healthy light does not contain ultraviolet and infrared light, does not produce radiation (ordinary light contains ultraviolet and infrared)
3 green do not contain mercury and xenon and other harmful elements, conducive to recovery and use, and will not produce electromagnetic interference (ordinary lamp contains mercury and lead, elements, energy-saving lamps, electronic ballasts will produce electromagnetic interference)
4. Protect eyesight DC drive, no strobe (normal lights are AC drive, will inevitably produce strobe)
5. High optical efficiency, small heat: 90% of electrical energy into visible light (ordinary incandescent 80% of electric energy into heat, only 20% of electrical energy into light energy)
6. The safety factor required voltage, current smaller, less heat, no security risk, can be used in mines and other dangerous places
7. The market potential low-voltage DC power supply, battery, solar power can be used for outdoor lighting in remote mountainous areas and the lack of electricity, less electricity places.
