Abstract
Abstract A luminous energizer for a plurality of fiber-optical cables comprises an aluminum heat-sink block formed with external cooling fins and a chamber closely receiving a halogen lamp. A plurality of passages in the block are aligned transversely of the lamp filament and lie in a common plane therewith. Each passage is provided with a light-conducting rod in heattransferring relation with the block. An end of a fiber-optical cable can be plugged into the end of each passage to receive light from the rod. Polarizing or color filters may be interposed between the end of the cable and the rod or otherwise built into the block.

Claim 1
Independent Claim
269 words
An apparatus for transmitting light, comprising, in combination: a massive solid heat-conductive aluminum block provided with a chamber generally centrally in said block and substantially surrounded by portions of substantially a major fraction of the thickness of the block; cooling fins formed on the exterior of said block for dissipation of heat to the surrounding atmosphere; a high-intensity halogen lamp received in said chamber and having its envelope closely surrounded by the material of said block, the wall of said chamber is formed with a lightreflecting coating; a metallic grid in said chamber between said envelope and said wall; a plurality of generally radially outwardly extending bores formed in said block and opening into said chamber, said lamp being provided with an elongated filament, said one of said bores extending transversely to said filament, said bores including two bores on each side of a plane through said body parallel to said filament, the bores on each side of said plane including acute angles with one another; respective solid light-conducting rods received in said bores and hugged by the material of said body for heat transmission thereto, said rods having inner ends closely juxtaposed with the envelope of said lamp; a flexible fiber-optical light conductor connected to said body at one of said bores and juxtaposed with the opposite end of one of said rods, said rods having a greater cross sectional area than that of the fibers of said conductor; an electrical transformer mounted on said block and connected with said lamp for electrically energizing same; and a light filter between said one of said rods and said conductor.
