Wind-solar complementary solar street lamp

Abstract

The invention discloses a wind-solar complementary solar street lamp which comprises a vertical column arranged on the ground, wherein a lamp pole is arranged on the vertical column, and a lamp body is arranged on the lamp pole. The vertical column is of a hollow structure, a support is arranged on the vertical column, a photovoltaic power generation panel is arranged on the support, a wind power generator is arranged at the top of the vertical column, storage batteries are arranged in the vertical column, and a bulb of the lamp, the photovoltaic power generation panel and the wind power generator are all connected to the storage batteries. According to the wind-solar complementary solar street lamp, the wind power generator and the photovoltaic power generation panel are utilized to generate power simultaneously as much as possible, generated energy is increased, capacity of the storage batteries is enlarged, continuous power supply time can be prolonged, electric energy can be provided as much as possible, problems caused by the fact that power generation of the photovoltaic power generation panel is limited by the weather can be solved, and popularization of solar energy technology is facilitated. The wind-solar complementary solar street lamp has the advantages of being shockproof and unlikely to break, and the service life of the wind-solar complementary solar street lamp is ten times longer than that of an ordinary bulb.

Description

technical field [0001] The invention relates to the application field of solar energy, in particular to a wind-solar complementary solar street lamp. Background technique [0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Thin-film solar cells that work on the photoelectric effect are the mainstream, while wet solar cells that work on the photochemical effect are still in their infancy. Generally, there are two ways of photoelectric conversion: 1. Light-heat-electricity conversion, which uses the thermal energy generated by solar radiation to generate electricity. Generally, the solar collector converts the absorbed heat energy into working medium vapor, and then drives the steam turbine to generate electricity. The former process is a photo-thermal conversion process; the latter process is a thermal-electric conversion process, which is the same as ordinary thermal power gen...

AI Technical Summary

Problems solved by technology

At present, there have been solar street lights, and its technology is relatively mature, but there is a defect in the current solar street lights: in the case of no sunlight for a long time, or when the daily exposure is insufficient, it is easy to cause insufficient power supply of the solar battery, or even turn off the lights. Moreover, in continuous rainy weather, the light is poor and the power generation is low, which is not enough to maintain normal use
