In one embodiment, the battery is electrically coupled through the conductive wire to conducting pin 378, which is mateable with a solar power output, such as port 380 defined by solar panel 372.
In one embodiment, solar panel 372 is rotatably coupled to roof support member 360. Solar panel 372 is electrically coupled to power module 384 of solar power generator 370. In a particular embodiment, solar panel 372 is electrically coupled to power source 385 including a storage battery housed within power module 384. The storage battery of solar power generator 370 is also electrically coupled to a socket 386. In a particular embodiment, a conductive wire extends through roof structure 332 and/or roof support member 360 to couple solar panel 372 to power source 385. Socket 386 includes a plurality of power ports (not shown) that are electrically coupled to the conductive wire and extend radially about an outer surface of socket 386. Additionally or alternatively, socket 386 includes a power port (not shown) that is electrically coupled to the conductive wire and extends generally coaxially with roof support member 360 from a bottom surface of socket 386.
Referring further to FIG. 20, a lighting device 390 is electrically coupled to solar power generator 370 and configured to receive electrical energy produced by solar power generator 370 for facilitating providing light to interior space 339 defined within gazebo 330. In one embodiment, lighting device 390 includes a plurality of pipe lights 394 having a LED indicator that is positioned within a corresponding transparent tube or pipe. In this embodiment, each transparent tube is coupled to roof structure 332 using a suitable coupling member, such as a clamp and/or a strap. Each pipe light 394 includes a power output end that is electrically coupled to a corresponding power port formed within socket 386. In an alternative embodiment, a light, such as a fluorescent light (not shown), is electrically coupled within the power port formed in the bottom surface of socket 386. It is apparent to those skilled in the art and guided by the teachings herein provided that any suitable number of lights and/or type of electrical lighting devices can be used with solar power generator 370 of the present invention for facilitating illuminating interior space 339 defined by gazebo 330.
In one embodiment, gazebo 330 is stored within a storage bag 400 in the collapsed configuration, as shown in FIG. 24. Storage bag 400 is made of any suitably durable material, such as a fabric material, and has any suitable size and/or configuration for facilitating storing gazebo 330 to prevent or limit undesirable exposure to environmental conditions when gazebo 330 is not being used. As shown in FIG. 24, storage bag 400 forms a pocket 402 within which solar power generator 370 is stored. In a particular embodiment, solar power generator 370 is stored within a case 404 that is positionable within pocket 402 to further protect solar power generator 370 from undesirable exposure to environmental conditions and/or contact with items that may damage the components of solar power generator 370.
The above-described apparatus and method facilitate illuminating an interior space defined by a collapsible structure, such as a tent or a gazebo. More specifically, the apparatus and method utilize photovoltaic principles to generate electrical energy from solar power obtained from the sun. As a result, in one embodiment electrical energy in the form of light is provided in an efficient, environmentally conscience and cost-effective manner.
Exemplary embodiments of an apparatus and method for providing a light source for facilitating lighting an interior space defined by a collapsible structure are described above in detail. The apparatus and method are not limited to the specific embodiments described herein, but rather, components of the apparatus and/or steps of the method may be utilized independently and separately from other components and/or steps described herein. Further, the described apparatus components and/or method steps can also be defined in, or used in combination with, other apparatus and/or methods, and are not limited to practice with only the apparatus and method as described herein.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
