I.Advantages of low carbon solar garden lamp:
With the increasing scarcity of earth resources and the increasing investment cost of basic energy, various safety and pollution hidden dangers are everywhere. Solar energy as a kind of "inexhaustible, inexhaustible" safe, environmental protection of new energy has been more and more attention. In this way, solar lighting products should be born after popularizing solar water heater. Here we make a practical comparison on the effect of solar courtyard lamp and using electric lamps.
Compared with the complex installation of a municipal electric garden lamp:
In the yard lighting project of municipal power, there are complicated operation procedures. First of all, cables must be laid. Here, a large number of basic projects, such as the excavation of cable trench, laying of dark pipes, threading in tubes and backfilling, are to be carried out. Then a long time of installation and debugging, if any line has problems, will have to rework a large area. Moreover, the terrain and wiring demand complex, manual and auxiliary materials cost high; Solar garden lights are easy to install: instead of laying complicated wiring, just make a cement base and fix it with stainless steel screws.
Compared with the high electricity cost of the courtyard lamp of the second municipal power station:
There is a fixed high electricity charge in the work of the courtyard lamp of municipal power, so it is necessary to maintain or replace the line and other configuration without interruption for a long time, and the maintenance cost increases year by year. Free electricity for solar lighting: the solar garden lighting is a one-time investment without any maintenance cost, and the investment cost can be recovered in three years for long-term benefit.
Comparison of three municipal power yard lights have safety risks:
Due to construction quality, landscape engineering transformation, material aging, abnormal power supply, water and electrical pipeline conflict, etc. Solar lamps and lanterns without safety risks: solar lamps and lanterns are ultra-low pressure products, safe and reliable operation.
II.Solar LED courtyard lights advantages:
1. Ultra-long life of semiconductor chip, no filament, no glass bubble, not afraid of vibration, not easy to be broken, service life can reach 50,000 hours (the service life of ordinary incandescent lamp is only 1,000 hours, the service life of ordinary energy-saving lamp is only 8,000 hours)
2. Light. Healthy light contains no ultraviolet and infrared rays and produces no radiation.
3. Environmental protection is free from harmful elements such as mercury and xenon, which is conducive to recycling and utilization, and will not produce electromagnetic interference (mercury and lead and other elements are contained in ordinary lamps, and the electronic ballast in energy-saving lamps will produce electromagnetic interference).
4. Vision protection dc drive, no stroboscopic (ordinary lamps are ac driven, which inevitably produces stroboscopic)
5. High light efficiency and low heat :90% of electric energy is converted to visible light (80% of ordinary incandescent lamp is converted to heat energy, and only 20% of electric energy is converted to light energy)
6. High safety coefficient requires less voltage and current, less heat, no potential safety hazard, can be used in dangerous places such as mine.
7. Market potential large low voltage, dc power supply, battery, solar power supply, can be used in remote mountainous areas and outdoor lighting and other power shortage, power shortage places.
Application range of solar LED courtyard lights：
Lighting and decoration for roads, commercial and residential areas, parks, tourist attractions, squares, etc. Also can according to the user needs the above places electric lighting system into solar lighting system.
