Abstract
An extremely lightweight, high-intensity illumination device utilizing polymer optical fibers to transmit light from a remote light source, and having a head-supported frame of the eyeglass type, in which the fibers are terminated in two or more bundles to provide a converging light pattern with minimal shadow effects. The remote light source employs a combination of dielectric mirrors and a heat-resistant glass rod to filter substantially all heat-producing infrared radiation from the light emitted by the source.
Claims23
A high-intensity, lightweight, head-supported illumination device, comprising:
- a light source having a high-intensity lamp and filtering means for removing heat radiation emitted by said lamp, said filtering means including at least one dielectric mirror for separating visible light from infrared radiation;
- light collecting means including heat-resistant glass for receiving filtered visible light from said dielectric mirror;
- lightweight, plastic fiber-optic light transmitting means adapted for connection to said light collecting means;
- head-supported means for securing said light transmitting means to the head;
- and
- means for terminating said light transmitting means at said head-supported means in such a manner as to project light forwardly of said head-supported means.
A high-intensity, lightweight, head-supported illumination device, comprising:
- a light source having a high-intensity lamp light collecting means, and at least one mirror for reflecting visible light from said lamp to said light collecting means, said mirror separating visible light from infrared radiation whereby heat emitted by said lamp is directed away from said light collecting means while high-intensity visible light is reflected thereto;
- lightweight light transmitting means including a plurality of polymer optical fibers and adapted for connection at a first end to said light collecting means in said light source to transmit light from said source through said optical fibers to a second end of said transmitting means;
- support means for securing said second end of said light transmitting means to the head of a user of said illumination device;
- and
- termination means for said second end of said light transmitting means for terminating said optical fibers at said support means in such a manner as to cause visible light from said source which passes through said optical fibers to project forwardly of said support means, whereby an area in front of the user of said illumination device is illuminated, and the area of illumination may be controlled by movement of the head of the user.
A high-intensity, lightweight, head-supported illumination device, comprising:
- an eyeglass frame including a bridge member and first and second side legs secured at opposite ends of said bridge member;
- polymer fiber optic light transmitting means having a first end adapted for connection to a high-intensity light source and a second end, said light transmitting means including a plurality of lightweight polymer optical fibers divided into first and second bundles at said second end;
- means rigidly securing said first bundle of fibers along said first side leg whereby said first bundle terminates adjacent a first end of said bridge member;
- means rigidly securing said second bundle of fibers along said second side leg, whereby said second bundle terminates adjacent a second end of said bridge member;
- lens means securable to said frame for terminating each of said first and second bundles, said lens means projecting and focusing light from said fibers forwardly of said frame;
- and
- means for securing said frame to the head of a user of said illumination device, whereby said light transmitting means extends along both sides of the user's head and projects light supplied to said fibers forwardly thereof.
