Abstract

A projection light source system and method of manufacture are shown in various embodiments. In one embodiment a single projector head (12) includes a light source (95) which projects through a condenser lens (90) and then an image transparency 120 which may be film or other digital media, and through an imaging lens 140 which is adjustable by rotation of a threaded cap 150. Adjustment of the image target location is achieved in part via an adjustment in the flange (20) which is rotatably connected to the head. Sequencing of images from a plurality of heads which are internally, remotely or IP controllable creates the ability project a succession of fixed images from a succession of heads either overlapping their target point or adjacent to create the effect of motion.

Claims

1. A projector lamp for projecting an image on a target, comprising:

a plurality of projection heads, each of the heads been individual units which are separately locatable and positionable and having;

a housing;

a light source;

a light condenser having a recess on one faces, said recess sized to receive at least part of the light source therein and surrounding at least part of the light source, the other face of the condenser including a domed projection surrounded by a circular recessed region;

a film transparency optically aligned with said light source;

an adjustable focusing head also optically aligned with said light source and said transparency, said focusing head is positionable along the focal axis to adjust the focus of said light source on the target.

2. The projection heads of claim 1 with a controllable light source within the housing.

3. The projection heads of claim 1 further including a programmable controller for actuating said light source with respect to any or all of the following parameters:

color, intensity, flashing, fading, latency or frequency of illumination.

4. The projector heads of claim 1 wherein the circular recessed region on the condenser includes a peripheral edge, a concave sloped circular region and a spherical domed region centrally within and extending outwardly from the concave region, to disburse the light source output evenly through the film.

6. The system of claim 1 wherein at least one projection head is positioned to point to substantially the same target and wherein the heads are sequentially activated to project different images, resulting the a visual effect of a moving image.

7. The system of claim 1 wherein at least one projection head is positioned to point to sequentially adjacent targets and wherein the heads are sequentially activated to project different images, resulting the a visual effect of a moving image across the adjacent targets.

5. A projector lamp for projecting an image on a target, comprising:

at least one projection head, having;

a housing;

a light source;

a light condenser having a recess on one faces, said recess sized to receive at least part of the light source therein and surrounding at least part of the light source, the other face of the condenser including a domed projection surrounded by a circular recessed region;

a film transparency optically aligned with said light source;

an adjustable focusing head also optically aligned with said light source and said transparency, said focusing head is positionable along the focal axis to adjust the focus of said light source on the target and wherein the at least one projection head contain controllers and timing is maintained by the frequency of AC line power, a carrier signal on a DC source, or a carrier signal on an AC source.

8. A method of simulating moving projected images from a plurality of separately movable light projectors comprising the steps of:

a. locating a plurality individual and separately locatable image projectors facing a target surface, said projector including at least one projectable image, each of the projectors having a different image;

b. aligning the focal points of each image projector to be at substantially the same location on the target surface;

c. sequentially illuminating the images the target surface, so that a viewer'"'"'s impression is that the image is moving.

9. The method of claim 8 wherein said images in said projectors are a sequential advance of the prior image and illuminating said projectors in the same sequences as the images.

10. The method of claim 8 further including the step of projecting an alignment beam from each of said light projectors on a single point on a target surface spaced from said projectors;

aligning said beams on said single point.

11. The method of claim 8 further including the step of projecting an alignment beam from each of said light projectors on a single point on a target surface spaced from said projectors;

aligning said beams on said single point, and then projecting said images sequentially after image alignment.

12. The method of claim 8 wherein said sequential illumination is a random order.

13. A projector lamp system for projecting an image on a target, comprising:

a plurality of projection heads each having;

a housing;

a light source;

an alignment beam;

a light condenser having a recess on one faces, said recess sized to receive at least part of the light source therein and surrounding at least part of the light source, the other face of the condenser including a domed projection surrounded by a circular recessed region;

a film transparency optically aligned with said light source;

an adjustable focusing head also optically aligned with said light source and said transparency, said focusing head is positionable along the focal axis to adjust the focus of said light source on the target;

whereby said alignment beam is projected from each head so that the heads may be positioned for convergence of their alignment beams on the target, so that when the images are projected from each head, they are aligned is aligned;

a sequential activator to sequentially activate the light source on each head so that the heads are sequentially activated to project different images, resulting the a visual effect of a moving image.
