Although this opening could be made circular, it has been found that such an elliptical shape will permit a substantially greater movement of the inner bezel l3 and lamp 29, thus increasing the adjustment limits of the light beam. The pivotal axis of the inner bezel I3 is the minor axis of the elliptical opening'in bezel" I I.
It is to be understood that the lighting fixture of the present invention may be mounted on walls or on any type of standard as well as on a ceiling and that the mounting plate I and mounting box 3 may be of many various shapes and contours.
It has been found in accordance with the present invention that such a novel lighting fixture may be adjusted so that the light beam can be directed to display counters as much as 45 beneath the fixture. When this lamp fixture is attached to any mounting, the exposed portion of the fixture presents a neat and finished appearance, and any adjustment of the lamp or the replacement of any component is exceptionally simple. In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.
. As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in limiting sense.
