Abstract
Abstract An illumination assembly for facilitating visual determination of the situs of an electrical terminal unit, the unit being mountable on a wall with a removable cover plate positioned in front thereof. The illumination assembly includes a light source for mounting adjacent the unit and behind the cover plate operable for producing illumination and an optical fiber communicating with the light source for transmitting illumination outwardly from the cover plate. Additionally, there is provided a transparent display element which is disposed adjacent the end of the optical fiber for concentrating illumination transmitted by the optical fiber and for also mounting the cover plate adjacent the unit.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
125 words
In an electrical terminal unit for mounting on a wall having a removable cover plate positioned in front thereof, an illumination assembly for facilitating visual determination of the situs of the unit comprising: a light source mounted adjacent the unit and behind the cover plate operable for producing illumination; optical fiber means communicating with said light source for transmitting illumination outwardly from the cover plate, said optical fiber means being dimensioned lengthwise for extending adjacent an aperture provided in the cover plate which normally accommodates reception of a fastener for mounting the cover plate adjacent the unit; and transparent display means disposed adjacent the end of said optical fiber means which extends adjacent the cover plate for concentrating illumination transmitted by said optical fiber means.
Claim 2
Dependent Claim
125 words
In an electrical terminal unit for mounting on a wall having a removable cover plate positioned in front thereof, an illumination assembly for facilitating visual determination of the situs of the unit comprising: a light source mounted adjacent the unit and behind the cover plate operable for producing illumination; optical fiber means communicating with said light source for transmitting illumination outwardly from the cover plate, said optical fiber means being dimensioned lengthwise for extending adjacent an aperture provided in the cover plate which normally accommodates reception of a fastener for mounting the cover plate adjacent the unit; and transparent display means disposed adjacent the end of said optical fiber means which extends adjacent the cover plate for concentrating illumination transmitted by said optical fiber means.
