Energy-saving solar street lamp

Abstract

The invention relates to an energy-saving solar street lamp. The solar street lamp comprises a lamp pole, wherein a solar panel is connected above the lamp pole through a support tube; an angle adjustable device is arranged between the support tube and the solar panel; one side of the lamp pole is provided with a street lamp; the solar panel is connected with a solar battery through a first control circuit; the street lamp is connected with the solar battery through a second control circuit; the second control circuit is also connected in series with a human body proximity sensor; and the street lamp is also connected with a light sensor. After the adoption of the above structure, the light sensor of the light pole senses the light, the street lamp is turned on when the light is dark, andthe street lamp is turned off when the light is bright, so that the aim of saving energy is fulfilled. Through the angle adjustable device, the angle adjustment of the solar panel is realized, and thesolar panel absorbing efficiency of the solar panel is improved.

Description

technical field [0001] The invention relates to a street lamp, in particular to an energy-saving solar street lamp. Background technique [0002] With the increasing shortage of global energy, green energy based on solar energy has been rapidly developed in various fields. Solar street lights use sunlight as energy, and sunlight shines on solar panels during the day, and the solar panels collect light energy to charge solar batteries. At night, the battery powers the light source, and it goes round and round; the general solar street light is controlled by a photosensitive switch, and the solar street light will not be on during the day; although this kind of solar street light saves energy, there is still a problem: the street light is on throughout the night. , Regardless of whether there are people or vehicles passing by, it will cause a waste of energy. If the weather is cloudy and rainy for several consecutive days, the power in the battery will be discharged, and the s...
