Garden lights are a kind of outdoor lamps, which can be used as decorative items during the day, and can be lit at night to bring us light.
Solar garden lamp is a kind of garden lamp, it uses solar radiation energy as energy, uses solar panels to charge the battery during the day, and the battery supplies power to the garden light source at night, without complex and expensive pipeline laying, the layout of the lamps and lanterns can be adjusted arbitrarily, safe, energy-saving and pollution-free, and energy-saving and environmental protection, in advocating green development today, it is a better outdoor lamp.
Analysis of the advantages and disadvantages of solar garden lights
Solar garden lights are composed of solar cell modules, brackets, light poles, lamp holders, special bulbs, batteries, battery boxes, ground cages and other parts made of monocrystalline silicon or polycrystalline silicon, which are widely used in the lighting and decoration of courtyards, parks, playgrounds, commercial and residential communities and other areas, this kind of solar garden lights have both advantages and disadvantages:
Advantages of solar garden lights
(1) Green environmental protection, high safety factor, small operating power, will not produce potential safety hazards, can also be recycled, small pollution to the environment, belongs to energy saving and environmental protection of green lamps.
(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, due to the use of semiconductor chips to emit light, no filament and glass bubbles, the cumulative life can reach tens of thousands of hours, higher than ordinary garden lights.
(4) The use efficiency is high, and it can effectively convert solar energy into light energy, and 90% of the electrical energy can be converted into visible light, which is much higher than ordinary incandescent lamps.
Disadvantages of solar garden lights:
(1) Instability, in order to make solar energy a continuous and stable energy source, so as to eventually become an alternative energy source that can compete with conventional energy, it is necessary to solve the problem of energy storage, that is, to store the solar radiation energy in the clear day as much as possible for use at night or on rainy days, but the energy storage problem is the weak point in the utilization of solar energy.
(2) The cost is higher, because of the efficiency and instability factors, the cost of solar garden lights is still relatively high, and the cost performance can not be compared with the traditional conventional outdoor garden lights, in order to further develop, it is necessary to solve the problem of economy.
