Energy efficient skylight and blind

A method of providing a seasonably variable barrier for the rays of the sun, comprising the steps of:

• mounting a plurality of slat members in a mounting frame, wherein each slat member has a thin cross-section and a larger surface having means formed thereupon for reflecting the rays of the summer sun;
• orienting and spacing-apart the slat members to pass the rays of the winter sunlight therebetween;
• and
• orienting the plurality of reflective surfaces on each slat to reflect back the rays of the summer sun out of the skylight assembly.

A system for guiding sunlight from a skylight assembly, comprising:

• a hollow tube having a hollow interior and having a first end for receiving sunlight from said skylight assembly and a second end for transmitting sunlight, said tube having internal walls for reflecting light from said first end to said second end;
• sunlight-transmitting fluid contained in the hollow interior of said hollow tube, said fluid permitting light to be transmitted therethrough from said first end to said second end;
• first sunlight-transparent means for capping the first end of said tube;
• and
• second sunlight-transparent means for capping the second end of said tube.

A method of guiding sunlight from a skylight assembly to one or more locations, comprising the steps of:

• transmitting sunlight from the skylight assembly through a first sunlight-transparent end cap on a first end of a hollow tube;
• guiding the sunlight transmitted through the first sunlight-transparent end cap into the hollow interior space of the hollow tube having an internal wall which reflects sunlight;
• transmitting the sunlight which passes through the first sunlight-transparent end cap and through the hollow interior space of the hollow tube;
• and
• transmitting the sunlight which passes through the hollow interior space of the hollow tube through a second sunlight-transparent end cap on a second end of the hollow tube.
