Energy source-saving streetlamp

Abstract

The invention discloses an energy source-saving streetlamp. The energy source-saving streetlamp comprises a streetlamp body and a power supply device, wherein the streetlamp body comprises a lamp post and a bulb; the power supply device is electrically connected with the bulb and comprises a power generation component and a storage battery electrically connected with the power generation component; the power generation component comprises a supporting post, a liquid cylinder, a power generation gear and a rack which is matched with the power generation gear; one end of the supporting post is fixed to a road surface; an inserting opening is formed in the bottom of the liquid cylinder; the supporting post goes into the liquid cylinder through the inserting opening; the liquid cylinder is fully filled with liquid which is easily expanded when being heated; the power generation gear is arranged on one side of the side wall of the liquid cylinder; an output end of the power generation gear is connected with a transmission; an output end of the transmission is connected with a power generation machine; an output end of the power generation machine is electrically connected with the storage battery. The characteristic of heat expansion and cold contraction of the liquid is used, and the renewable solar energy serves as a power source, so that the utilization rate of solar energy is high, and the generated power can substantially satisfy the needs of night illumination of the streetlamp.

Description

technical field [0001] The invention relates to a road lighting facility, in particular to an energy-saving street lamp. Background technique [0002] Street lamps generally refer to lamps within the range of road lighting in traffic lighting. Street lights are often installed on one side or both sides of the road, usually including a lamp post and a light bulb installed on the top of the light post, wherein the light bulb is electrically connected to the power supply device, and the light bulb is generally used to provide a brighter view for pedestrians at night. [0003] For now, the stock of street lamps in China is about 28 million to 30 million. In recent years, the number of new street lamps has increased by 15% to 20% every year, about 3 million to 6 million. According to statistics, the current annual power consumption of urban lighting (only counting functional lighting such as landscape lighting and street lamps) accounts for about 4% to 5% of China's total power ...
