Description

Self-powered LED street light {Independent power style LED street lamp}

The present invention relates to a street lamp, and more particularly, to an LED street lamp that is capable of self-power generation using a solar cell.

In general, street lamps installed on the side of the street are supplied with electricity by a timer, central control, and sensors using commercial power as a power source, and the lamp adjacent to the side of the street is turned on by lighting a lamp using a high pressure mercury lamp, a fluorescent lamp, or a sodium lamp as a light source. It is to illuminate more than illumination.

However, the above-mentioned conventional streetlight has a problem of losing a lot of power since it is almost turned on at night regardless of the illuminance of the surrounding environment by using commercial power, especially the moonlight or the bright morning Since the lights continue to light up, it is a waste of power loss nationally.

In addition, there is a problem due to the loss of manpower as well as the replacement cost, because the frequent replacement of the light source.

Such a conventional streetlight uses a commercial AC power supplied from the outside without artificial power generation facilities as a power source, which requires a lot of management and maintenance costs, and has a problem that an electric shock accident occurs due to the exposure of underground power lines during flooding.

Recently, there is a growing interest in alternative energy to cope with the depletion of fossil fuels and to reduce the pollution caused by fossil fuels.

The alternative energy industry has the disadvantage that the initial facility cost is high, but solar power generation is not only rich in resources than other alternative energy industries, but also low in installation cost and relatively limited in the region. Attention is on the rise.

Currently, solar power generation is known as a pollution-free power generation facility that produces electricity without pollution because it can be installed and used without restriction in areas and topography, such as a building rooftop in a downtown area or a roof of a house, if there is a large amount of sunshine.

In view of this, development of self-powered street light using solar cells is required.
