Multiple Focus Point Light

A lighting device comprising:

• a light source forming light;
• a lens, having movable parts, said movable parts moving to define both in focus and out of focus locations of the lens, and defining first locations which can be brought into focus by said moving and also can be brought out of focus by said moving, and second locations which are always out of focus;
• first and second optical elements, in a first path location to receive said light from said light source, both said first and second optical elements being in first locations which can be brought into focus, but where only one of said first and second optical elements can be in focus at any one time, said first and second optical elements being located between said lens and said light source;
• third and fourth optical elements, located in a second path location, on an opposite side of said lens from said light source, and receiving light from said light source that has passed through said first and second optical elements, and where only one of said third and fourth optical elements can be in focus at any one time, but where one of said first and second optical elements can be in focus at the same time as one of said second and third optical elements;
• at least one lens part moving motor, moving said movable parts of said lens to bring said optical elements into focus;
• and
• a controller, controlling said at least one lens part moving motor to bring one of said first and second optical elements into focus at the same time as one of said second and third optical elements.

A method of controlling production of light, comprising:

• forming light using a light source;
• moving movable parts of a lens that has movable parts, said moving to defining both in focus and out of focus locations of the lens;
• defining first locations which can be brought into focus by said moving and also can be brought out of focus by said moving, and second locations which are always out of focus;
• locating first and second optical elements, in a first path location to receive said light from said light source, both said first and second optical elements being in first locations which can be brought into focus, but where only one of said first and second optical elements can be in focus at any one time;
• locating third and fourth optical elements, located in a second path location, on an opposite side of said lens from said light source, and receiving light from said light source that has passed through said first and second optical elements, and where only one of said third and fourth optical elements can be in focus at any one time, but where one of said first and second optical elements can be in focus at the same time as one of said second and third optical elements;
• and
• controlling said moving to bring one of said first and second optical elements into focus at the same time as one of said second and third optical elements.
