1. How about the garden light for Solar lamps?

The courtyard light is an Outdoor lamp. It can be used as decorative items during the day. At night, the Lights can be emitted to bring us light. Many parks, squares and other areas will be installed with courtyard Lights.

Solar courtyard Lights are a type of garden lamp. It uses Solar radiation energy as energy. It uses Solar panels to charge the battery during the day. At night, the battery is used to power the courtyard light source.Safe energy saving and pollution -free, and energy saving and environmental protection. Today, it is a better outdoor lamps that advocate green development.

2. Analysis of the advantages and disadvantages of Solar garden Lights

Solar courtyard Lights are composed of Solar battery components, brackets, brackets, light rods, lamp heads, special light bulbs, batteries, battery boxes, floor cages, etc.Regional lighting and decoration, such Solar garden Lights have both advantages and disadvantages:

1. The advantages of Solar garden Lights

(1) Green and environmental protection, high safety factor, small operating power, no hidden safety hazards, can also be recycled, small pollution to the environment, is a green lamps with energy saving and environmental protection.

(2) The light is healthy, the light of the Solar courtyard light is soft and not dazzling. The light does not contain ultraviolet and infrared rays, does not generate radiation, and has no light pollution.

(3) Life is long. Because the semiconductor chip is glowing, there is no filament and glass bubbles, and the accumulated life can reach tens of thousands of hours, which is higher than ordinary courtyard Lights.

(4) High use efficiency, can effectively convert solar energy into light energy. 90%of the power can be converted into visible light, which is much higher than ordinary incandescent lamps.

2. Disadvantages of Solar garden Lights

(1) Unstable, in order to make solar energy continuous and stable energy, and ultimately become an alternative energy to compete with conventional energy, we must solve the problem of energy storage well, that is, storage of sun radiation energy as much as possible.For night or rainy days, the problem of energy storage is the weakness of Solar use.

(2) The cost is high. Because of the efficiency and instability, the cost of Solar courtyard Lights is still relatively high. The cost -effectiveness cannot be compared with traditional conventional Outdoor courtyard Lights. To further develop, it needs to solve economic problems.
