1. A light fixture having a light source for forming a multi-color pattern upon a surface, comprising:
- (a) at least one dichroic filter mountable within the beam of the light source such that incident light reflected by said dichroic filter and incident light transmitted by said dichroic filter cooperate with light from said light source which is not incident upon said dichroic filter to form a multi-color pattern upon the surface.

Abstract
A light fixture for providing an aesthetically pleasing multi-colored pattern of illumination is disclosed. The light fixture comprises a housing for mounting a light bulb, a plurality of dichroic filters positioned within the beam of the light bulb, and a mounting fixture for securing and positioning the dichroic filters. Each of the dichroic filters will typically have different optical properties such that the reflected and transmitted light from each dichroic filter contributes a different color to the pattern. A second embodiment having an adjustable filter positioning means is also disclosed.

11. A light fixture having a light source for forming a multi-color pattern upon a surface comprising:
-
(a) first and second dichroic filters mountable within the beam of the light source such that incident light reflected by said dichroic filter and incident light transmitted by said dichroic filter cooperate with light from said source which is not incident upon said dichroic filters to form a multi-color pattern upon the surface; (b) a housing within which the light source is mounted and to which said dichroic filters are attachable; (c) wherein said dichroic filters are mounted such that their planar surface forms an angle of approximately 105 degrees to light incident from the light source; and (d) wherein light reflected from the first dichroic filter forms a first beam of a first color, the first beam forming an angle of approximately 30 degrees to the light incident from the light source, (e) wherein light transmitted by the first dichroic filter forms a second beam of a second color, the second beam forming an angle of approximately 0 degrees to the light incident from the light source; (f) wherein light reflected from the second dichroic filter forms a third beam of a third color, the third beam forming an angle of approximately 30 degrees to the light incident from the source; (g) wherein light transmitted by the second dichroic filter forms a fourth beam of a fourth color, the fourth beam forming an angle of approximately 0 degrees to the light incident from the light source; and (h) the first, second, third, and fourth beams are each of different colors.

12. A light fixture having a light source, for forming a multi-color pattern upon a surface, comprising:
-
(a) a housing for containing the light source; (b) an elongate support post attached to said housing; (c) a filter mount attached to said support post; (d) at least two dichroic filters attached to said filter mount; (e) wherein the dichroic filters are mounted such that their planar surface forms an angle of approximately 105 degrees to light incident from the light source; (f) wherein light reflected from the first dichroic filter forms a first beam of a first color, the first beam forming an angle of approximately 30 degrees to the light incident from the light source; (g) wherein light transmitted by the first dichroic filter forms a second beam of a second color, the second beam forming an angle of approximately 0 degrees to the light incident from the light source; (h) wherein light reflected from the second dichroic filter forms a third beam of a third color, the third beam forming an angle of approximately 30 degrees to the light incident from the light source; (i) wherein light transmitted by the second dichroic filter forms a fourth beam of a fourth color, the fourth beam forming an angle of approximately 0 degrees to the light incident from the light source; and (j) wherein the first, second, third, and fourth beams are each of different colors.
