Street lamp with power supplied by solar energy

Abstract

The invention discloses a street lamp with power supplied by solar energy. The street lamp comprises a stand column, one end of the stand column is fixed into the ground, and a solar panel supporting rod and a lamp supporting rod are arranged at the other end of the stand column. A solar panel is arranged on the solar panel supporting rod through a rotating device, a light sensor is arranged on the solar panel, and a bulb is arranged on the lamp supporting rod. The solar panel is connected with a solar charging wire and composed of two solar panel bodies which make contact to form an umbrella shape. The bulb is connected with a solar power supply wire, and the solar charging wire and the solar power supply wire are both connected with a storage battery. An inner cavity is formed in the stand column, and the storage battery is arranged in the inner cavity of the stand column. The stand column is provided with a charging port which is connected with the storage battery through a wire and used for supplying external power to the storage battery when the electric quantity of the storage battery is not enough. The failure rate of the street lamp can be lowered, and the solar utilization rate is increased; the street lamp has a rain shielding function and is suitable for continuously working in rainy days for a long time.

Description

technical field [0001] The invention relates to a street lamp, in particular to a street lamp powered by solar energy, and belongs to the technical field of road lighting equipment. Background technique [0002] Street lights, as an indispensable public facility, play a very important role. However, most of the existing street lamps are line lamps, that is, street lamps that pull wires like residential lamps. Often, the street lamps cannot be used due to various circuit failures, such as area maintenance, fire, etc., so the failure rate of street lamps is high. people's quality of life. And, when it rains, people need to look for a place to shelter from the rain, and these places are mostly far away from the street lamps, which is quite inconvenient especially when the rainy night is darker; Therefore, it is beneficial to design a street lamp with a rain-shielding function. At the same time, existing solar street lights cannot continue to work in continuous rainy weather,...

AI Technical Summary

Problems solved by technology

At the same time, the existing solar street lights cannot continue to work in the case of continuous rainy weather, so a backup power supply solution is needed to ensure the normal operation of the street lights even in long-term rainy days

[0003] In addition, the solar modules on the current solar street lamps are all fixed, and due to some shortcomings of solar energy resources, such as low density of sunlight, intermittent irradiation time, and changing spatial distribution, the intensity of sunlight varies with time. With the constant change of time, this makes the sunlight resources not fully utilized, wasting the solar energy resources

In the prior art, in order to make the solar cell components of the solar street lamp emit enough electricity to provide street lighting, the wattage of the solar cell components has to be increased, but the production cost of the solar street lamp has been increased.
