Abstract: Disclosed is a projection display apparatus in which the optical axis of a lamp and that of an optical unit can be easily made coincide with each other irrespective of dimensional variations of component parts. A lamp holder (32) is movably attached to a ride side plate (37) of a lamp case by extension springs (63). The center of a lamp (1) is positioned on the optical axis (20x) of an optical unit (20) by a circular arc wall face (32f) of the lamp holder (32) and a V-shaped member (45) fixed to the optical unit (20). The optical axis (1x) of the lamp (1) and the optical axis (20x) of the optical unit (20) are set to be parallel to each other by a slide reference face (20a) of the optical unit (20) and three projections of the lamp holder (32). Since the lamp holder (32) is not fixed to a lamp house, an influence of accumulation of dimensional variations of components such as the lamp house exerted on the adjustment of the optical axes of the lamp (1) and the optical unit (20) can be minimized.

Abstract: A beacon light assembly shield for shield from ground level the light emitted by tower mounted beacon lights for aircraft, the assembly comprising a plurality of spaced concentric frustraconically shaped elements having a centrally located aperture, the element being interconnected, and each element being spaced from an adjacent element such that a distance between a first horizontal plane coincidental with an inner peripheral edge and a second horizontal plane coincidental with an outer peripheral edge is no greater than 75% of a distance between first horizontal planes of adjacent elements. The assembly effectively eliminates light pollution from ground level while permitting visual access for aircraft.

Abstract: A holder for detachably mounting a glass electric lamp dome which includes a pair of dome holding arms mounted to a lever arm which in turn is pivotally mounted on a base plate. The lever arm and the dome holding arms are actuated by a finger engageable lever formed as part of one of the dome holding arms and having a finger engageable terminus at the end opposite the end attached to the pivot arm. A feature is spring biasing means connecting the base plate and the lever arm to continuously urge the dome holding arms outwardly in dome holding locking position unless the finger engageable dome holding arm is moved inwardly. Another feature is lock means associated with said finger engageable dome holding arm to premit the locking of said mechanism in a dome disengaging position so that the dome can be removed and replaced.
