Description
Technical field
The utility model relates to a kind of optical road lamp technology, particularly a kind of Solar Street Lighting System with commercial power parallel.
Background technology
Photovoltaic generation is also referred to as solar electrical energy generation, photovoltaic generation is a kind of technology utilizing the photovoltaic effect of interface and luminous energy is directly changed into electric energy, photovoltaic generation is owing to having non-environmental-pollution, without exhausted danger, not by restriction and the energy quality advantages of higher of resource distribution region, more and more causing the attention of people.Street lamp is as the indispensable part of urban road, consume a large amount of city electricity consumptions, existing solar street light have employed battery mostly, and the useful life of battery is only 1.5 to 2 years, unit use cost is far above interchange electricity consumption, very uneconomical, solar street light is installed is regarded as greatly wasting possessing the city of Alternating Current Power Supply condition, suburbs and counties under the jurisdiction of a large city and Highways '.
Utility model content
The utility model provides a kind of Solar Street Lighting System, and it draws together micro-inverter, LED street lamp, photovoltaic generation unit and controller;
Described micro-inverter is connected with described photovoltaic generation unit, and described photovoltaic generation unit converts solar energy to direct current and is sent to described micro-inverter, and described direct current is converted to alternating current by described micro-inverter; Described micro-inverter output end comprises one first relay, and described first relay is electrically connected with city, and described first relay controls opening and closing by described controller, and during described first relay closes, described alternating current is incorporated to described civil power;
Have one second relay in described micro-inverter, one end of described second relay of described city's electrical connection, the other end of described second relay is connected with described LED street lamp.
Preferably, described controller is respectively by the opening and closing sending the first relay, the second relay described in the signal of telecommunication to described first relay, the second Control.
The utility model does not need battery to carry out accumulate, all civil power is incorporated with by the electrogenesis of the photovoltaic generation unit by each street lamp, and be street lamp power supply, road lamp power supply by civil power again when night needs street lamp, the balance between supply and demand making Solar Street Lighting System reach daytime and night is loaded; The utility model does not adopt battery electric power storage simultaneously, and cost obtains very large reduction, and avoids the loss of accumulator cell charging and discharging.
Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described describing the required accompanying drawing used to embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
