Abstract

The utility model provides a solar street lamp. The solar street lamp comprises an MPPT (maximum power point tracking) controller, an LED (light-emitting diode) lamp, a solar panel and a solar storage battery, wherein the solar storage battery is connected with the MPPT controller; the MPPT controller is connected with the LED lamp; and the solar panel is connected with the MPPT controller. According to the solar street lamp, electrical power is provided to the street lamp through solar energy, the problem of energy resources is not considered while excellent illuminating and decorating effects are ensured, the aim of green saving energy is fulfilled, the limit of a wire is avoided, and the conversion efficiency from solar energy to the electric power is high.

Description

A kind of solar street light

Technical field

The utility model relates to the street lamp technical field, particularly a kind of solar street light.

Background technology

The street lamp that prior art provides all is to adopt public electric wire net electric power that the needs of illumination in evening are provided; If on a road, lay many this street lamps; Need a very huge electric wire networking; Divide to give,, will lose their original illumination and decorative effects if cable has fracture or has a power failure to individual street lamp power supply, road lamp power supply.

The utility model content

The utility model provides a kind of solar street light, need not the restriction of civil power and the efficient height that converts electric power into of solar energy.

To achieve these goals, the utility model provides following technical scheme:

A kind of solar street light, it comprises: MPPT controller, LED lamp, solar panels and solar storage battery, wherein:

Said solar storage battery connects said MPPT controller, and said MPPT controller connects said LED lamp, and said solar panels connect the MPPT controller.

Through implementing above technical scheme; Has following technique effect: the solar street light that the utility model provides; Through solar energy is that street lamp provides electric power, in the illumination that guarantees to provide good, decorative effect, need not to consider energy problem; Reach the green energy conservation purpose and do not receive the restriction of electric wire, and the solar energy of this solar street light to convert the efficient of electric power into high.

Description of drawings

The structure principle chart of the solar street light that Fig. 1 provides for the utility model embodiment.

The specific embodiment

In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The utility model embodiment provides a kind of solar street light, and is as shown in Figure 1, and this solar street light comprises: MPPT (MPPT maximum power point tracking solar energy) controller 101, LED lamp 102, solar panels 104 and solar storage battery 103, wherein:

Said solar storage battery 103 connects said MPPT controller 101, and said MPPT controller 101 connects said LED lamp 102, and said solar panels 104 connect said MPPT controller 101.

The solar street light that the utility model embodiment provides is that street lamp provides electric power through solar energy, in the illumination that guarantees to provide good, decorative effect, need not to consider energy problem, reaches the green energy conservation purpose and does not receive the restriction of electric wire.

And owing to adopted the control of MPPT controller, traditional solar charging electrical efficiency is improved more than 50%, can more than enoughly store the energy more than 50% every day like this.Adopt the LED lamp, illuminance efficiently is provided, guarantee to have every day enough electric power to give the work of LED lamp.

More than a kind of solar street light that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.

Claims (1)

1. a solar street light is characterized in that, comprising: MPPT controller, LED lamp, solar panels and solar storage battery, wherein:

Said solar storage battery connects said MPPT controller, and said MPPT controller connects said LED lamp, and said solar panels connect the MPPT controller.
