Abstract

An arrangement for variably mounting an illumination device in an enclosure, such as a safety sign, is provided with a longitudinal track having a longitudinal engagement portion. One or more illumination devices are provided with associated mounting feet for engaging slidably with the longitudinal engagement portion of the track. The track then is fixed onto a pair of stanchions having a respective plurality of engaging portions so that any of several heights can be achieved with respect to a base portion of the stanchion. Engagement of the mounting feet and the longitudinal track is effected by a longitudinal bent portion of the track that defines a space therewithin that accommodates the mounting feet. In addition, the longitudinal track accommodates the engagement portions of the stanchion for supporting the longitudinal track at the desired height. In this manner, the positions of the illumination devices can be adjusted along two dimensions whereby the luminance of the illumination devices can be positioned in desired relation to the printing on a translucent panel of a fixture that bears a printed message, as would be the case with an exit sign. An electrical coupling arrangement permits the illumination device to be coupled electrically to pre-existing enclosures. This enables existing antiquated safety illumination systems to be fitted easily with modern internal components that comply with applicable codes and standards.
