Abstract: A computer keyboard includes a plurality of keys arranged in a pattern contained within a plane, a webbed structure defining openings for each of the keys, an illumination source, and one or more light pipes positioned along the webbed structure and arranged to deliver light from the illumination source to the keys, wherein each of the keys is illuminated thereby. Although the keys have the appearance of being backlit similar to traditional illuminated keyboards, the illumination source is actually located along at least one side of and within the same plane as the pattern of keys, rather than beneath the keys. The keyboard can thus be made thinner in such arrangements where the illumination source does not need to be located beneath the keys.

Abstract: A lighting fixture includes at least one optic and at least one coherent light source for directing at least one substantially coherent light beam towards the at least one optic. Light provided from the at least one optic comprises an observable illuminated speckle patterned surface resulting from the coherent light beam.
