1.Energy is an important guarantee for social and economic development, and vigorously developing renewable energy is the main way to solve the energy crisis. With the improvement of people's living standards, the enhancement of environmental awareness, the attention to human sustainable development and physical health, expanding the human demand for pollution-free, environment-friendly and energy-saving lamps.
Solar LED garden lamp with solar radiation for energy, using solar panels to the battery during the day and night use battery to power a high photosynthetic efficiency of LED light source, without complex and expensive pipeline laid, can be arbitrary adjust the layout of the lamps and lanterns, safety and energy saving no pollution, no manual work is stable and reliable operation, saving electricity maintenance free .
Solar courtyard lamp technology
Solar panel: high efficiency single/polycrystalline silicon solar panel, power: 35-100wp;
Working voltage: 12V/DC;
Storage battery: maintenance-free solar battery with a capacity of 38--150Ah/12V; Light source: low-power LED light, high-power bulb light;
Controller: microcomputer intelligent controller, over charge, over discharge, reverse connection protection, light control + time control;
2.Advantages of low-carbon solar courtyard lamps:
With the scarcity of earth resources and the increasing cost of basic energy investment, various safety and pollution risks are everywhere. Solar energy as a "inexhaustible, inexhaustible" safety, environmental protection of new energy more and more attention. In this way, solar lighting products should be born after the popularity of solar water heaters. Here we make a practical comparison between the effect of solar courtyard lamps and the use of municipal lamps and lanterns.
Comparing the complex installation of a mains courtyard lamp:
There are complicated operation procedures in the yard lamp project of mains power. First of all, cables should be laid. Here, a large number of foundation works, such as excavation of cable trench, laying concealed pipes, threading inside pipes and backfilling, should be carried out. Then carry out a long time of installation and debugging, if any one line has a problem, then a large area of rework. And the terrain and line requirements complex, labor and auxiliary materials cost is high; Solar patio lights are easy to install: instead of laying complicated wiring, they are installed on a cement base and fixed with stainless steel screws.
Compared with the high electricity cost of yard lights in the second city:
There are fixed and high electricity charges in the work of yard lights of mains power. It is necessary to maintain or replace the lines and other configurations continuously for a long time, and the maintenance cost increases year by year. Solar lighting lamps are free of electricity charge: solar courtyard lamps are one-time investment without any maintenance cost, which can recover the investment cost in three years and benefit for a long time.
Comparing the three power supply courtyard lights, there are safety risks:
Because of the construction quality, landscape engineering renovation, material aging, abnormal power supply, water and electrical pipe conflict and so on, the garden lamp of municipal power has brought a lot of hidden dangers. Solar lamps have no hidden danger: solar lamps are ultra-low voltage products, safe and reliable operation.
