Abstract

537,165. Lighting systems. PHILIPS LAMPS, Ltd. April 18, 1940, No. 7048. Convention date, April 21, 1939. [Classes 75 (ii) and 75 (iv)] A lighting installation, for instance a landing light for aerodromes, consists of a number of piled units each containing a light-source and a mirror or lens, and the direction of the beam from each unit is adjustable relatively to the direction of the beams from the other units. The installation shown in the Figure consists of a number of piled prismatic units 2, 3, 4 each containing a linear light-source 26, a parabolic mirror 7, and in some cases a cooling system. Each unit is provided with screws 10, 11, 12 which rest in cavities in the subjacent unit and which are a adjustable to adjust the direction of the beam. The mirror of each unit may be pivoted coaxially with the light-source and be adjustable by means of a hand-wheel and a screw-device. Incandescent lamps in conjunction with mirrors shaped as paraboloids of revolution may be used. The mirrors may be replaced by lenses.
