I. How about solar lights for garden lights
Garden lights are outdoor lamps, which can be used as decorative items during the day, and can be used for lighting at night. Bright, garden lights will be installed in many parks, squares and other areas, so is it good to use solar lights for garden lights?
Solar garden light is a kind of garden light. It uses solar radiation energy as energy. During the day, it uses solar panels to charge the battery. At night, the battery supplies power to the garden light source, without complicated and expensive pipeline laying. The layout of the lamps can be adjusted arbitrarily, which is safe, energy-saving, pollution-free, and energy-saving and environmentally friendly. Today, when green development is advocated, it is a better outdoor lamp.
Second, analysis of the advantages and disadvantages of solar garden lights
Solar cell modules, brackets, light poles, lamp holders made of monocrystalline silicon or polycrystalline silicon for solar garden lights , special light bulbs, batteries, battery boxes, ground cages and other parts, widely used in the lighting and decoration of courtyards, parks, playgrounds, commercial and residential quarters and other areas, this solar garden light has both advantages and disadvantages:
1. Advantages of solar garden lights
(1) Green environmental protection, high safety factor, low operating power, no potential safety hazards, and can be recycled, The pollution to the environment is small, and it belongs to the green lamps of energy saving and environmental protection.
(2) The light is healthy, the light irradiated by the solar garden light is soft and not dazzling, the light does not contain ultraviolet and infrared rays, does not produce radiation, and has no light pollution.
(3) Long service life, because the semiconductor chip is used to emit light, without filament and glass bulb, the cumulative life can reach tens of thousands of hours, which is higher than ordinary garden lights.
(4) High use efficiency, can effectively convert solar energy into light energy, 90% of electric energy can be converted into visible light, much higher than ordinary incandescent lamps.
2. Disadvantages of solar garden lights
(1) Unstable, in order to make solar energy a continuous and stable energy source, it will eventually become a Alternative energy sources that compete with energy must solve the problem of energy storage well, that is, to store the solar radiation energy during the sunny day as much as possible for use at night or in rainy days, but the problem of energy storage is the weak point in the utilization of solar energy.
(2) The cost is high. Because of efficiency and instability factors, the cost of solar garden lights is relatively high, and the cost performance cannot be compared with traditional conventional outdoor garden lights. Economic issues need to be addressed.
