Hello,

Has anyone heard of hybrid lighting.

Its a method(I think developed in Japan) where a big silver satellite
dish is place onto a roof then opric fibres tranmit the sun light and
transport it to room below. I understand that this reduces lighting
power consumption in large sky-scrapers.

I'm interested to use this in my house to bring sunlight into the east
facing rooms. I don't have the space to install a sunpipe but maybe
optic-fibres will do.

I'm interested to know if anyone has experience of this technology.

Many Thanks
Neil


Theres also a much simpler cheaper technology that does something
similar.

Because the incoming reflected skylight goes up to the ceiling, this
roughly method doubles the light level in a room.

If you want you can then add some tronics to a fl light to modulate it
so it maintains the chosen light level as daylight dims, thus saving
energy. You might find other ways that can save more energy than that.
In a skyscraper the total lighting load is pretty large, so it becomes
well worthwhile.
