Abstract
An adjustable ring light for concentrating multiple beams of light in which the point of convergence can be moved along an axis. In an embodiment, the light sources which may be the ends of bundles of optical fibers, are mounted in tiltable carriers which are adjusted by rotation of a housing cover. In other embodiments tilting is accomplished by bending tabs or rotating a disk having slots through which the light sources project.
Claims11
Adjustable illuminating apparatus for concentrating multiple beams of light at a predetermined point comprising:
- a. housing means having a plurality of annularly arranged spaced openings;
- b. means within said housing means for supporting a source of a light beam at each of said openings;
- c. means for biasing each of said supporting means to direct the light from each source out through said openings to converge;
- d. adjusting means on said housing means to contact said supporting means and overcome said biasing means to pivot each of said supporting means thereby to alter selectively along an axis the region at which the beams of light from said sources converge;
- and
- e. said biasing means comprising disk means having radially directed slots mounted within said housing means with each of said supporting means passing through one of said slots for limiting the direction of movement of said supporting means caused by said adjusting means so that the region of convergence of said light beams is adjustable along said axis.
Illuminating apparatus for concentrating multiple beams of light at a predetermined point comprising:
- a. means having a central axis for supporting a plurality of annularly arranged spaced sources of light beams;
- b. means enclosing said supporting means for adjusting simultaneously the angle of said sources so as to effect the movement of said point along said axis;
- and
- c. a disk attached to said enclosing means within said supporting means for carrying an annular array of tabs whose outer extremities are in contact with said housing means, means in said tabs to mount said sources to direct said beams to converge at said point, and means to effect movement of said enclosing means with respect to said supporting means to change the angle of said tabs thereby to change the angle of said beams of light and move along an axis their point of convergence.
Illuminating apparatus for concentrating multiple beams of light at a predetermined point comprising:
- a. means having a central axis for supporting a plurality of annularly arranged spaced sources of light beam projecting from said supoprting means;
- b. means enclosing said supporting means for adjusting simultaneously the angle of said sources so as to effect the movement of said point along said axis, and
- c. disk means attached to said enclosing means being penetrated by said sources, whereby rotation of said enclosing means with respect to said supporting means causes said sources to contact a portion of said disk means to tilt and thereby change the angle of light beams and move their point of convergence.
Adjustable illuminating apparatus for concentrating multiple beams of light at a predetermined point comprising:
- a. housing means having a plurality of annularly arranged spaced openings;
- b. means within said housing means for supporting a source of a light beam at each of said openings;
- c. means for biasing each of said supporting means to direct the light from each source out through said openings to converge,
- d. adjusting means on said housing means to contact said supporting means and overcome said biasing means to pivot each of said supporting means thereby to alter selectively along an axis the region at which the beams of light from said sources converge;
- and
- e. disk means in contact with said supporting means to limit movement of said sources so that all light beams pass through said axis.
