Abstract

The invention discloses an LED (Light-Emitting Diode) illuminating lighthouse adopting a graphene solar power generation system. The LED illuminating lighthouse is characterized by comprising an illuminating lighthouse body, wherein the illuminating lighthouse body comprises an outer-layer tower body and an inner-layer tower body; the outer-layer tower body is connected with the inner-layer tower body through brackets; graphene solar panels are arranged on the outer-layer tower body; the inner-layer tower body is provided with a battery pack and a charging controller; an illuminating system is arranged on the top of the inner-layer tower body; the battery pack is connected with the illuminating system. Graphene is taken as a semiconductor material for solar photoelectric conversion, so that the efficiency of solar photoelectric conversion is increased; moreover, the graphene solar panels are arranged circumferentially along the the inner-layer tower body, so that a photovoltaic effect can be generated by making full use of sun illumination, and the aim of photoelectric conversion of solar energy is fulfilled; moreover, an LED lamp has long service life and is environmentally-friendly, maritime environment pollution can be lowered, and energy is saved.

Description

technical field [0001] The invention relates to an LED lighting lighthouse using a graphene solar power generation system, belonging to the technical field of lighting systems. Background technique [0002] Our country has a long coastline and many islands. At present, sea transportation is frequent. It is very necessary to build lighting lighthouses on the islands to indicate the direction, prevent the risks of reefs and dangerous beaches, and solve the problem of ships breaking down in bad weather. Solar energy is used for lighting. The power provided by the lighthouse can not only prevent the pollution of the sea area, but also avoid the construction of large-scale transmission lines. [0003] Solar photoelectric conversion is mainly based on semiconductor materials, using light to generate electron-hole pairs, which can generate photocurrent and photovoltage (photovoltaic effect) on the PN junction, so as to achieve the purpose of solar photoelectric conversion. The com...
