Abstract

318,605. Cassan, G. Sept. 8, 1928, [Convention date]. Vehicle lamps.-In a vehicle lamp provided with an electric lamp bulb 4 having its filament 3 coinciding with the centre of a downwardly directed hemispherical reflector 2 and with the focus of a half paraboloidal reflector 5, the latter is arranged behind the transverse vertical plane passing through the filament. The axis of the reflector 5 may be horizontal or slightly downwardly inclined. The lamp casing 7 is closed by a bell glass 6 provided on its front face with horizontal prisms 8 or with vertical grooves.
