ADJUSTABLE EXPOSITIONAL LAMP

摘要

The invention relates to the field of lighting, in particular to an adjustable exposure lamp, designed to illuminate the objects of the exhibition at exhibitions, in museums. The technical result achieved when using the claimed utility model is to regulate the size of the light spot of a non-circular shape. The problem is solved in that in the luminaire, which consists of a hinged busbar adapter, power supply module and optical module, the optical module contains a hood, a flat-faceted lens, two surface diffusion film diffusers and a light emitting element with a LED mounted on the radiator. The light-emitting element moves along the axis of the optical module housing along guides. To do this, a blind threaded hole is made in the radiator, with which the screw interacts. The screw rotates in the hole in the transverse cross member mounted on the end of the optical module housing and is equipped with a manual feed handwheel. Film diffuser with axisymmetric indicatrix with a diameter equal to the diameter of the lens, adjacent to the flat side of the lens surface scattering. A film diffuser with a biaxymmetric indicatrix is built into the hood with a scattering surface directed toward the lens. The hinge element between the adapter and the power supply module is a nipple, between the power supply module and the optical unit is a hollow bolt. 1 hp f-s, 4 ill.
