Description

Turbine and lighting system such as the urban lighting or the like comprising such a wind turbine.

The invention relates to a wind turbine and a lighting system such as the urban lighting or the like comprising such a wind turbine.

We know the horizontal axis wind turbines and vertical axis wind turbines, the latter in two characteristic types: the type called "Savonius" and the guy says "Darrieus" names of their designers, respectively, Finnish and French in the 1920s to 1930 (subsequently, these wind turbines will be respectively called Darrieus wind and Savonnius).

The rotor of the Savonius wind turbine typically comprises two semi-cylindrical cups having their axes slightly offset with respect to one another. Such a wind turbine has the advantage of having a relatively small footprint and can start even at relatively low wind speeds. However, it has the drawback of not developing great powers and have a low yield.

The rotor of the Darrieus wind turbine has blades (or fins or called profiles). It may be subject to various achievements: cylindrical rotor, tapered rotor ... With a parabolic rotor blades - usually numbering two or three - are bent in troposkein and fixed in the upper part and lower part the vertical axis. Such a wind turbine has the advantage of a very good yield. Instead, it presents as hard starting problem.

US-A-4 200 904 discloses a street lighting system (such as typically street lighting, paths, roads ...) comprising a mast, an illuminating device carried up the mast including a conventional light bulb, a solar panel placed masthead supplying batteries. It is expected, optionally, a horizontal axis wind turbine propeller-type, so that the system can operate all year at all times.

US-A-6,601,984 describes an illumination system of the same type, ie comprising a solar panel is a horizontal axis wind turbine. The lighting device comprises a plurality of light guides arranged in parallel, each rod-shaped, comprising one or two emitting electrodes (LED) at one or both ends. WO-03/044870 describes a lighting system of the same type, powered by solar or wind energy, wind vertical axis being here. The lighting device comprises a plurality of LEDs arranged in parallel with each other, carried by a support adjustable in position with respect to an optical part to view the illumination angle, in the same manner and for all LED same time and in the same way.

In the lighting systems described in these documents, the wind is not optimized.

Furthermore, WO-2006/060 905 discloses a street lighting device comprising two panels mounted so as to be inclined relative to each other, each panel having a plurality of LEDs placed side by side with the same inclination.

US-A-6,676,279 and US-A-6,705,744 describe an urban lighting device comprising an LED reduced number which may be directed each to the target area to provide the target surface in the light intensity desired.

These documents do not disclose that these light fixtures would be aimed at providing a medium illuminance of the illuminated surface of the order of at least twenty lux on an area which may reach and even exceed twenty meters in length on more than five meters in width, avoiding the existence of highly lit areas and too dimly lit areas.

The invention is first to provide a wind turbine whose part in particular is optimized to power, especially, feeding a lighting device (such as typical city lighting, paths, roads .. .) using renewable energy and clean (wind and solar if applicable), without requiring a power infrastructure, and without expenditure of energy. Optimization is such that the lighting device can operate independently, even with a poor quality of wind, and from any direction whatsoever, and optimized way, even with a strong wind. It is such that the bulk and weight of the wind turbine part are limited, so that it can be worn on the head portion of a conventional lighting mast without requiring any particular reinforcement and without discomfort (visual, hearing ...) excessive. Optimization is such that safety is ensured even in case of strong wind. In addition, the wind turbine is sturdy enough to not require a major service and maintenance, which makes it particularly suitable when available for that purpose few resources or costly resources. The wind generator is also protected against attacks and intrusion of dust, dirt, insects, small animals ... that might disrupt the operation or affect its lifespan.

The invention then is that the wind turbine is adapted to an illumination device, itself intended to be part of an illumination system having a plurality of LEDs that provides a means illuminance of the illuminated surface ( typically the ground) of the order of at least twenty lux on a surface that can reach and even exceed twenty meters in length more than five meters in width.
