Energy-saving LED street lamp

Abstract

The invention discloses an energy-saving LED street lamp. The energy-saving LED street lamp comprises a lamp rod, a supporting table and a supporting rod, wherein the lamp rod is composed of an upperrod body and a lower rod body, the supporting table is fixedly connected with the upper rod body, the supporting rod is fixedly arranged on the upper portion of the left side of the lower rod body, and a movable connecting cavity is formed in the bottom in the upper rod body; a rotating pin shaft part is fixedly arranged on the top of the lower rod body, the top of the rotating pin shaft part penetrates through the bottom of the upper rod body and extends into the movable connecting cavity, a limiting block part is fixedly arranged at the tail end of the top of the rotating pin shaft part, anda conical tooth disc part is arranged on the top of the limiting block part; the supporting table is fixedly arranged in the position, outside the right side of the movable connecting cavity, of on the upper rod body, a second sliding groove is formed in the top of the supporting table, a second moving block and a second threaded rod are arranged in the second sliding groove, and the second moving block is in threaded fit connection with the second threaded rod; a first cavity is formed in the supporting table of the left side of the second sliding groove, a second cavity is formed between the bottom of the left side of the first cavity and the top of the right side of the movable connecting cavity, and the left side of the second threaded rod penetrates through the wall body of the supporting table and extends into the first cavity and is in rotating fit connection with the first cavity.

Description

technical field [0001] The invention relates to the field of LED street lamps, in particular to an energy-saving LED street lamp. Background technique [0002] As a clean energy source, solar energy has always been the direction of exploration for human beings to make full use of solar energy. Solar street lights are not affected by power supply, do not consume conventional electric energy, and can be installed on-site as long as the sun resources are sufficient, so they are widely used and concerned. Solar street lights must use solar cell components to provide electrical energy. For different regions and seasons, the installation inclination and azimuth of solar cell components are different. Traditional solar LED street lights have a single fixing method and complex structures. The adjustment angle is limited, so Can not get sufficient lighting effect, so can not fully perform photoelectric conversion, resulting in low conversion utilization of solar energy. Contents of...

Solar street lights must use solar cell components to provide electrical energy. For different regions and seasons, the installation inclination and azimuth of solar cell components are different. Traditional solar LED street lights have a single fixing method and complex structures. The adjustment angle is limited, so Can not get sufficient lighting effect, so it can not fully perform photoelectric conversion, resulting in low conversion utilization rate of solar energy
