Solar street lamp system for highway

Abstract

The invention provides a solar street lamp system for a highway. The solar street lamp system for the highway comprises a remote street lamp control subsystem and a solar thermal power station and compressed air energy storage unit combined operation device. At night, when no pedestrian or vehicle passes, street lamps slightly light, and when approaching of an object is detected, the street lampsare fully lighted; in the morning or evening, the street lamps are automatically switched on and off according to the brightness change of ambient light. The solar energy and compressed air energy storage combined operation device achieves steady output of power of a solar thermal power station. The technical problems that in the prior art, a power generating system of the solar street lamp systemfor the highway is unsteady in operation and power is seriously wasted are solved; intelligent control of the solar street lamp system for the highway and the technical effect of steady operation ofthe power generating system are achieved.

Description

technical field [0001] The invention relates to the technical field of solar street lamps, in particular to a solar street lamp system for expressways. Background technique [0002] It has become more and more common to install street lighting systems on expressways. It can be said that street lights are the main component of expressways and play a pivotal role in preventing traffic accidents on expressways. But while street lights play an important role, they also consume a lot of energy. At present, the general traditional street lamps are mainly high-pressure sodium lamps. The power of a street lamp is about 100-400W, and the power of some large street lamps can reach more than 1000W. With a street lamp of 200W, it will consume 200×12 / 1000=2.4 kilowatt-hours of electricity if it is illuminated for 12 hours a night. Assuming that the distance between street lamps is 20 meters, there are 2×2000 / 20=200 street lamps on a 2-kilometer expressway, and the electric energy consu...
