Energy-consumption-free all-day caution lamp

Abstract

The invention relates to the field of solar energy generation, in particular to an energy-consumption-free all-day caution lamp, which is manufactured by using novel amorphous silicon solar photovoltaic panels as power generation devices. A caution lamp body has a cuboid structure, wherein the amorphous silicon solar photovoltaic panels are arranged on the upper surface and the four side faces of the caution lamp body; light-emitting diodes (LEDs) are arranged below the photovoltaic panels on the four side faces; the amorphous silicon solar photovoltaic panels are made from optical glass or the resin with high transmittance; the surfaces of the photovoltaic panels are distributed in the shape of quadrangular table arrays; antireflection silicon nitride films are plated on the surfaces of the photovoltaic panels; and amorphous silicon power generation layers are plated on the bottom faces of the photovoltaic panels. The caution lamp can absorb scattered rays in the surrounding space, and can generate electric energy in a cloudy or rainy day through weak light discharge, so all-day caution is realized; and automobile light can be absorbed by the surfaces of slightly conical tower lens structure arrays, so reflection is avoided.

Description

technical field [0001] The invention relates to the field of application of solar power generation, in particular to a non-energy-consuming all-weather warning light made of a new type of amorphous silicon solar photovoltaic panel as a power generation device. Background technique [0002] At present, there are two main forms of solar energy that people use: photovoltaic power generation and photothermal. In recent years, more and more photovoltaic power generation technologies have entered people's field of vision, and solar energy has taken an increasing proportion in the social energy structure and played an increasingly important role in the national economy. Solar photovoltaic power generation is a major aspect of solar energy utilization. Currently, commonly used solar cells include monocrystalline silicon cells, polycrystalline silicon cells and amorphous silicon thin film cells. In some European and American countries, due to some preferential policies of the govern...

Problems solved by technology

Ordinary warning lights are powered by wires or dry batteries. The disadvantage is that they cannot work on their own for a long time and require long wires or frequent replacement of batteries.

Especially in some dangerous places or high places, the work of laying wires and replacing batteries is more inconvenient
