Miniature coaxial lighting assembly
First Claim
1. A versatile miniature coaxialy-configured lighting assembly for architectural quality illumination and display purposes in residential and commercial environments, comprising,(a) a cylindrical base body, at least partially enclosing lamp connector means, said base body having an enclosed rear end, an outer cylinder wall region, and a front end having a forward-extending, outside-threaded, coaxial tubular flange,(b) a tubular midsection body having a rear end inside-threaded to mate with the outside-threaded flange at the front end of said base body, an outer wall region, an inner wall region, and a front end having a forward-extending, outside-threaded, coaxial tubular flange,(c) a low voltage prefocused reflector type lamp located within the front end of said midsection body, electrically and mechanically engaging the lamp connector means,(d) a tubular barrel having a rear end inside-threaded to mate with the ouside-threaded flange at the front end of said midsection body, an outer wall region, an inner wall region, and a front end,whereby said midsection body may be removably coupled in coaxial relationship with said base body by threading onto the front end of the base body, and whereby said barrel may be removably coupled in coaxial relationship with said midsection body by threading onto the front end of the midsection body.

Abstract
A miniature lighting instrument for high quality architectural and display purposes features a sectionalized coaxial configuration. A base body, available with either a side- or rear-entry mounting adaptor, either fixed or swivel, is threadedly coupled to a midsection body available with a choice of smooth surface, lateral cooling ribs or fluted cooling ribs. The midsection body encloses an optical quality low voltage prefocused reflector type lamp. A selection of front barrels is available for threadedly coupling onto the front of the midsection body. The selection includes a long barrel for narrow-beam spotlighting, a short barrel for wide-beam floodlighting, a side-throw barrel for ultra-wide-angle floodlighting, and a projector barrel assembly with a front mounted lens and adjustable threaded mid-coupling for focusing. The many combinations made available by flexible interchangeability allow a lighting designer to customize the light instrument for particular tasks and to create novel and unusual artistic lighting display effects.

16. A process for assembling component parts of a coaxially-configured miniature lighting instrument designed particularly for architectural quality purposes in residential and commerical environments, in accordance with this invention, comprising the steps of
(a) selecting a base body fitted with a lamp socket, (b) selecting a midsection body from a group of tubular midsection bodies having different configurations such as smooth, lateral-ribbed or fluted exterior surface, (c) attaching the selected midsection body onto the selected base body, using mating threads provided at the rear end of the midsection body and at the front end of the base body, (d) selecting a low voltage prefocused reflector lamp having light beam width suited to an intended illumination requirement, (e) inserting the selected lamp into the front end of the midsection body so as to engage the lamp socket located within the base body. (f) selecting a tubular barrel from a group of barrels having different lengths for different light beam widths so as to best address the intended illumination requirement, (g) selecting at least one optical disk from a group comprising filters, diffusers, fixed iris, adjustable iris, special lenses, clear protector and the like, (h) inserting the optical disk into the rear end of the barrel and locating it against a mounting surface provided, (i) securing the optical disk in place by pressing a compliant O-ring into the barrel against the rear of the disk, (j) attaching the selected barrel onto the selected midsection body using internal threading provided at the rear end of the barrel to mate with external threading provided at the front end of the midsection body.
