Illuminator for exposing color television tubes during the manufacturing process thereof and the like

Claim 1

A light projection apparatus comprising: a. a first double focal point reflector having a major axis and first and second focal points along the major axis thereof; b. a light source fixed at the first focal point of said first double focal point reflector such that at least some of the light rays therefrom are reflected by said first double focal point reflector to said second focal point thereof; c. a second double focal point reflector having a major axis and first and second focal points along the major axis thereof, said major axis of said second reflector being aligned with the axis of said first reflector, said first focal point of said second double focal point reflector being substantially coincident with said first focal point of said first double focal point reflector and said second focal point of said second double focal point reflector being spaced from said second focal point of said first double focal point reflector. d. light gathering and projecting means positioned on said axis approximately at said second focal point of said first double focal point reflector for projecting gathered light incident thereto, toward an object to be illuminated, as substantially a point source; and e. reflecting means having a central axis aligned with the major axes of said first and second reflectors and positioned approximately at said second focal point of said second double focal point reflector for focusing light reflected from said second double focal point reflector to said second focal point of said first double focal point reflector.
