LED CLUSTER ARRANGEMENT WITH RELATIVE ROTATION, TRANSLATION, AND MIRROR IMAGE ORIENTATION
A light-emitting diode (LED) lighting fixture includes a substrate and a plurality of LED clusters disposed on the substrate in a plane in which two orthogonal axes defining a two-dimension coordinate system is disposed. At least two of the LED clusters have orientations which are relatively angularly displaced and/or mirrored within the two-dimensional coordinate system.
1 . A lighting apparatus comprising at least four separate clusters of light emitting diodes (LEDs) fixedly positioned in a series along one single line upon a substrate which substrate defines a plane, each of the clusters having one or two, but less than three, other clusters adjacent thereto, wherein:
each cluster comprises a foursquare array having four interior quadrants, each quadrant of the cluster mounting an LED of a different color than any other quadrant in the cluster; and
each cluster having a position upon the substrate wherein the position of a second cluster is rotated by ninety degrees, on the plane of the substrate, in relation to an adjacent first cluster.
2 . The lighting apparatus according to claim 1 wherein the cluster positions alternate along the substrate whereby every other cluster has the same arrangement of colored LEDs.
3 . A luminaire fixture comprising at least four separate clusters of light emitting diodes (LEDs) positioned linearly along one single line upon a substrate which substrate defines a plane, each and every of the clusters having one or two, but less than three, other clusters adjacent thereto, wherein:
each cluster comprises a foursquare array having four interior quadrants, each quadrant of the cluster mounting an LED of a different color than any other quadrant in the cluster; and
each cluster having a position upon the substrate wherein the position of a first cluster is rotated by one hundred and eighty degrees, on the plane of the substrate, in relation to an adjacent second cluster.
4 . The luminaire fixture according to claim 3 wherein the cluster positions alternate along the substrate whereby every other cluster has the same arrangement of colored LEDs.
5 . A luminaire fixture comprising at least five clusters of light-emitting diodes (LEDs) fixedly positioned in a series along only one line upon a substrate which substrate defines a plane, each of the clusters having one or two, but less than three, other clusters adjacent thereto, wherein:
each cluster comprises a foursquare array having four interior quadrants, each quadrant of the cluster mounting an LED of a different color than any other quadrant in the cluster; and
the position of a second cluster is rotated by ninety degrees, on the plane of the substrate, in relation to an adjacent first cluster;
the position of a third cluster adjacent to the second cluster is rotated one hundred and eighty degrees, on the plane of the substrate, relative to the first cluster;
the position of a fourth cluster adjacent to the third cluster is rotated two hundred and seventy degrees, on the plane of the substrate, relative to the first cluster; and
the position of a fifth cluster adjacent to the fourth cluster is rotated ninety degrees, on the plane of the substrate, relative to the fourth cluster, whereby a configuration of the LEDs of the fifth cluster is the same as a configuration of the LEDs of the first cluster.
6 . A lighting apparatus comprising at least four separate clusters of light emitting diodes (LEDs) fixedly positioned in a series along one single line upon a substrate which substrate defines a plane, each of the clusters having one or two, but less than three, other clusters adjacent thereto, wherein:
each cluster comprises a foursquare array having four interior quadrants, each quadrant of the cluster mounting an LED of a different color than any other quadrant in the cluster; and
each cluster having a position upon the substrate wherein the position of a second cluster is rotated on the plane of the substrate, in relation to an adjacent first cluster or having a position upon the substrate wherein the position the four interior quadrants of a second cluster are arranged as a mirror image on the plane of the substrate, in relation to an adjacent first cluster.
