PUBLISHED APRIL 29, 1969 782,704 SEQUENTIAL PHOTOMETER FOR MEASURING OUTPUT OF A VEHICLE MOUNTED LAMP William N. Moroney, Detroit, Mich., assignor to Ford Motor Company, Dearborn, Mich., a corporation of Delaware Filed Dec. 10, 1968. Published Apr. 29, 1969 Int. Cl. G01j 1/00; Hillj 39/12 US. Cl. 356121 1 Sheet Drawing. 6 Pages Specification A testing apparatus for photometrically testing the light distributive candlepower of vehicle mountable lamp assemblies. The lamp (13) to be tested is positioned in predetermined relationship to a plurality of photocells (15) each of which is located at a specific test point. The surface of each photocell is located an equal radial distance from the lamp filament. The photocells are sequentially activated by means (16) and the excitation of each cell is measured by a digital voltmeter (17) and recorded by a recorder (18) in terms of candlepower value.
