ES2315165A1 - Supply to the mains network and sale of electric energy produced by photovoltaic cells, adapted for use on the tops of lamps used on illuminated roadways (fedes) - Google Patents

Abstract

The invention concerns installation on the streetlights forming part of an illuminated roadway, of a series of photovoltaic cells adapted and located along the column of the streetlight, so that the "wind band" effect is avoided, overall aesthetics are respected and striving for a completely south-facing orientation for greater exploitation of solar radiation. The other components such as the direct/alternate current converter, protective devices and night/day switch, will be housed in the junction box at the base of the streetlight. In this way the basic structure thereof is not changed in any respect. The energy produced by said photovoltaic cells is converted into alternating current and supplied to the mains through the electric installation already existing in the interior of the column of each streetlight.

Description

Special energy saving lampposts, with photovoltaic cells adapted and coupled to the shape of the staff for energy production and discharge to the general electricity grid.

Object of the invention

In general terms, it is about taking advantage the thousands of street lamps that exist in the street lights, to produce electrical energy with photovoltaic cells adapted to staff of these street lamps, and thus take advantage of the existing infrastructure At night in lighting and by day generating energy that is injected into the power grid when more it is necessary.

Background of the invention

Road lighting is an important factor to Take into account road safety. So schematic, the system consists in the development of a system able, to transform a public lighting, so necessary and with high costs for municipalities, in an economic lighting to the once ecological, capable of reducing CO2 emission, causing environmental pollution. The system will take advantage the existing road lighting electrical infrastructure and the will transform into authentic generators of electrical energy.

With this, the municipalities will get reduce electricity consumption during peak hours, with a cost of maintenance equal to the existing facilities.

The increasing volume of traffic still complicates plus the situation and the need for new infrastructure increases, in an attempt to release congestion from the main network and from urban areas, the increase in this traffic increases the effects harmful to the environment and public health, and in special, the economic expenses that derive so much from its consumption As of its maintenance.

Explanation of the invention.

The main objective of the project is saving energy in street and street lighting, while a reduction in CO2 emissions.

It's about installing on the street lamps that road lighting comprises a series of photovoltaic cells, in equal amount of power Wp, than that consumed by each lamppost (about 300 Wp). The energy produced by these photovoltaic cells is converted into alternating current and discharged to the network through the own existing installation that runs through the interior of the staff of each lamppost.

The photovoltaic cells will be located at along the lamppost staff, so that the effect is avoided of the wind on the plates, taking care of the aesthetics of the whole. Seeking a pure south orientation for greater use of solar radiation.

The DC / AC converter, protections and switch day / night, will be housed in the box registration located at the base of the street lamps. So, of this mode, the basic structure of the same will not be altered.

It is intended, in short, to provide lighting public and road of an incentive for the recovery of the investment in facilities and maintenance, through the discharge of energy produced to the general power grid.

Description of the drawings

For the best understanding of how much is left described herein, some drawings are attached in the that, just as an example, a case study is represented of realization of a basic public lighting:

Figure 1 shows a side view of a single luminaire or lamppost according to the invention.

Figure 2 shows a basic installation or example of street lighting, as a whole.

Preferred Embodiment of the Invention

In view of the commented figures and of according to the numbering adopted, it can be observed in them an example of preferred embodiment of the luminaire or lamppost, the which comprises the parts indicated below:

one-

Luminaire or lamp post.

2-

Photovoltaic cell coupled and adapted to the shape of the staff, facing south.

3-

Registration box for protection housing electric.

4-

Lamp set "F1, F2, F3, F4 ..." in undetermined number of "Fn" elements, with cells South-facing coupled photovoltaic, necessary for each transformation center

5-

DC to AC converter for the set of street lamps.

6-

Counter and rush module.

7-

Discharge to the general power grid.

In this way, as can be seen in the Figure 1, the photovoltaic cell (2) is coupled and adapted to the staff (1) of street lighting lamps, along the same with a south orientation. The necessary food for it is it lodges in the base of the staff in the register box (3).

The energy produced by the capture of these cells will serve to be spilled into the general network, as you can observe in figure 2.

Describe sufficiently the nature of the The present invention, as well as how to implement it, is it states that, within its essentiality, it may be taken to the practice in other embodiments that differ in detail from the one indicated by way of example, and which will also reach the protection that is collected as long as it is not altered, changed or Modify your fundamental principle.

Claims (1)

1. Special energy-saving lampposts for the discharge to the general electrical network of the electrical energy produced by photovoltaic cells characterized by carrying coupled photovoltaic cells coupled and adapted to their shape, which will be responsible for producing energy to be poured to the general network.
