Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new wind powered lamp embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the wind powered lamp 10 generally comprises an elongate shaft 11 having a first end 12 mountable to a support structure. A generator 21 for generating electrical energy is mounted to a second end 13 of the shaft 11. The generator 21 is rotatable about the longitudinal axis of the shaft 11 to generate electrical power. A housing 24 substantially encloses the generator 21. The housing 24 has a plurality of rotor blades 25 extending in a direction radially outwards from the longitudinal axis of the shaft 11. The housing 24 is coupled to the generator 21 such that rotation of the housing 24 rotates the generator 21 about the longitudinal axis of the shaft 11 to generate electrical energy. A plurality of light sources 27,28 are also substantially enclosed in the housing 24 and are electrically connected to the generator 21.
In closer detail, the elongate shaft 11 is preferably generally cylindrical and has opposite first and second ends 12,13, and a longitudinal axis extending between the first and second ends 12,13 of the shaft 11. The first end 12 of the shaft 11 is mountable to a support structure preferably by a mounting bracket 15 coupled to the first end 12 of the shaft 11. The mounting bracket 15 has a center hole 16 and a plurality of outwardly radiating mounting arms 17. The first end 12 of the shaft 11 is extended through the center hole 16 of the mounting bracket 15. A pair of nuts 18,19 are threaded onto a threaded portion 14 of the first end 12 of the shaft 11 with the mounting bracket 15 disposed between the nuts 18,19 on the shaft 11 so that the nuts 18,19 couple the mounting bracket 15 to the first end 12 of the shaft 11. The mounting arms 17 of the mounting bracket 15 are designed for mounting the mounting bracket 15 to a support structure. Each of the mounting arms 17 of the mounting bracket 15 has a hole 20 therethrough designed for extending fasteners therethrough to mount 26 the mounting arms 17 to the support structure.
A generator 21 for generating electrical energy when rotated is mounted to the second end 13 of the shaft 11. The generator 21 is rotatable about the longitudinal axis of the shaft 11 to generate electrical power as it is rotated. Preferably, the generator 21 has a rotating portion 22 and a fixed portion 23. The fixed portion 23 is fixedly coupled to the shaft 11 such that the rotating portion 22 of the generator 21 may rotate about the longitudinal axis of the shaft 11 to generate electrical energy. A housing 24 encloses the generator 21. The housing 24 has a plurality of rotor blades 25 extending in a direction radially outwards from the longitudinal axis of the shaft 11. In use, the rotor blades 25 are designed for rotating the housing 24 about the longitudinal axis of the shaft 11 by wind blowing against the rotor blades. The housing 24 is fixedly coupled to the generator 21 such that rotation of the housing 24 rotates the generator 21 about the longitudinal axis of the shaft 11 to generate electrical energy. Ideally, a mount 26 having a plurality of outwardly radiating arms couples the generator 21 to the housing 24 with threaded fasteners and nuts.
A plurality of light sources 27,28 are enclosed in the housing 24. The light sources is electrically connected to the generator 21 such that electrical energy from the generator 21 illuminates the light sources. Preferably, each of the light sources comprises an LED. With particular reference to FIG. 5, the light sources are divided into first and second sets of light sources 27,28. Each light source of the first set of light sources 27 is paired with an associated light source of the second set of light sources 28. The light sources of the first set of light sources 27 are arranged in a first directional series and the light sources of the second set light sources is arranged in a second directional series opposite the first directional series such that rotation of the generator 21 in a first direction illuminates the light sources of the first set of light sources 27 and rotation of the generator 21 in a second direction illuminates the second set of light sources 28. This way if winds blow from opposite directions to thereby rotate the housing 24 in opposite directions, at least one set of light sources will be illuminated.
The housing 24 is generally translucent to permit passage of light from the light sources out through the housing 24. Ideally, the housing 24 is generally transparent and comprises a generally clear plastic material. The housing 24 preferably has front and back portions 29,30 each having a generally arcuate cross section and a generally circular perimeter edge 31,32. The front and back portions 29,30 are coupled together along their perimeter edges 31,32. As illustrated in FIG. 3 the perimeter edge 32 of the back portion 30 of the housing 24 preferably has a diameter less than the distance across opposite mounting arms 17 of the mounting bracket 15. The rotor blades 25 are located on the front portion 29 of the housing 24 and extending outwards from the perimeter edge 31 of the front portion 29. The generator 21 is mounted to the back portion 30 of the housing 24. The back portion 30 also has a hole through which the shaft 11 extends. The light sources 27,28 are coupled to the inside of the back portion 30 of the housing 24. Each light source of the first set of light sources 27 is positioned adjacent the associated light source of the second set of light sources 28. The pairs of light sources are spaced apart from each other and arranged in a ring extending adjacent the outer perimeter of the back portion 30 of the housing 24.
In use, wind blows over the rotor blades to rotate the housing and thus the generator to generate electrical energy to illuminate the light sources.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
