Novel solar street lamp high in power generating efficiency

Abstract

The invention relates to the field of street lamp illumination, in particular to a novel solar street lamp high in power generating efficiency. The street lamp is large in power consumption, solar street lamps are already gradually adopted to replace traditional mains supply street lamps for illumination in various regions under the situation that national energy-saving and emission-reducing policies are constantly strengthened and are welcomed in the illumination market with the green, environmentally friendly, power-consumption-free advantages and the like of the lamps, but the popularization of the solar street lamps in the illumination market is limited due to the defects such as low photovoltaic power generation efficiency and non-effective illumination in rainy days. Under the situation of the same photovoltaic installation capacity, if the photovoltaic power generation efficiency can be improved, the situation that the solar street lamps cannot perform illumination in rainy days can be greatly improved. The invention provides a technology for adjusting the dig angle of a street lamp solar panel. The photovoltaic panel can always face the sun and receive more solar direct radiant quantity. Compared with solar street lamps identical in installation capacity and changeless in dip angle, the photovoltaic power generation amount can be improved by about 40%.

Description

technical field [0001] The invention relates to the field of street lamp lighting, in particular to a novel solar street lamp with high power generation efficiency. Background technique [0002] With the continuous strengthening of the national new energy conservation and environmental protection policy, gradually reducing coal-fired power generation and increasing the use of renewable energy will be the development direction of the country's future energy policy. Public lighting such as highways and road lighting are large power consumers. Urban public lighting electricity consumption accounts for 30% of my country's lighting power consumption, accounting for 10-12% of the country's total power generation. Therefore, the use of solar street lights to replace traditional city circuit lights can be regarded as an important means of energy saving, emission reduction, and air pollution control. The advantages of solar street lights, such as green environmental protection, no pow...
