Abstract: Portable solar powered light sources, devices, apparatus, systems and methods of attaching and using the light source. The light sources can have a single small housing having an upper roof portion with an exposed solar cell, a photocell activator, and small housing. The housing can have two parts that pivot with one another so that a front end of the housing can be biased together by a spring, and the rear side having edges that are spaced apart. An operator can press the rear spaced apart edges together, to open the front end to slide about a support structure, such as an open umbrella fabric edge. The housing allows for the light source powered by batteries to be activated by the photocell during dark (night) conditions), with the light direction being adjustable underneath. During daylight, the solar cell receives sunlight to charge the batteries within the housing.

Abstract: An air-exhausting apparatus, device, method of assembly and use for an attic and rooftop fan, which prevents water intrusion into the housing. The fan can include a tubular base having a bottom side mounted on a roof of a room, and an upper end portion converging toward a top side of the base. A coupling sleeve unit has a first coupling end portion sleeved fixedly on the base and cooperating with the base to define an annular draining passage therebetween, and a second coupling end portion opposite to the first coupling end portion. A fan unit is mounted in the coupling sleeve unit, and is operable so as to exhaust air outwardly of the room via air holes in the second coupling end portion of the coupling sleeve unit. A cover unit includes a cover body disposed on the second coupling end portion of the coupling sleeve unit, and a supporting frame interconnecting fixedly the cover body and the coupling sleeve unit. Wear and/or sound absorbers can also be included.
