#2771: Glowindow

I’ve been searching for this idea but still not found any examples in eg patent databases….so here goes.

Today’s invention is replacement glazed units for small windows which contain extra bright daylight lamps, shining inwards.

For a small window, this gives the impression of a much wider opening and makes the atmosphere in a darkish room brighter. The brightness level could be computer controlled to mirror (or compensate for) the external daylight level. It could also replace existing SAD lamps.

Keeping the aperture size small also controls heat loss via the window.
