Compact LED light source and lighting system

A method of lighting a target area with a composite light output pattern comprising:

• a. controlling orientation of four or more LEDs each mounted on a thermally conductive substrate having at least four planar faces corresponding to a thermally conductive base having four planar faces in a compact module relative the target area in a non-parallel and co-planar orientation, each LED adapted to produce an individual light output pattern, wherein the controlling of orientation is such that one or more individual light output patterns at least partially overlaps one or more other individual light output patterns so to produce a composite light output pattern;
• b. controlling the composite light output pattern of the oriented LEDs with a device at the compact module, wherein the controlling of light output is such that the composite pattern is of a defined shape, wherein the device comprises a light transmissive cover encapsulating the LEDs, the light transmissive cover designed to modify at least one of the initial light output patterns;
• c. mounting the compact module relative the target area on a bollard-type support, wherein the mounting is such that the composite light output pattern is of a defined size;
• and
• d. the compact LED light source module is pivotable relative the support such that by selective design of the light transmissive cover and pivoting of the module said composite light output pattern of defined shape and size is produced.

A compact, adaptable system for illumination comprising:

• a. at least four LED light sources each having a light output axis and a light output distribution pattern about the light output axis;
• b. a compact mount for the at least four LED light sources so that the light output axes of the at least four LED light sources are non-parallel and co-planar, wherein a plane of the light output axis is parallel to a desired target location of the light output distribution pattern, the compact mount comprising a thermally conductive substrate having at least four planar faces corresponding to a thermally conductive base having four planar faces;
• c. a light transmissive cover over the at least four LED light sources designed to modify at least one of the LED light source light output distribution patterns;
• d. a cut-off component mounted at or near the cover and in at least a portion of one or more light output patterns so to cut-off a portion of said one or more output patterns;
• e. the compact LED light source module is pivotable relative the support such that by selective design of the light transmissive cover and pivoting of the module said composite light output pattern of defined shape and size is produced;
• f. so that customizable composite light output distribution patterns can be produced by selection of the at least four LED sources, their output distribution patterns, optical characteristics of the cover, positioning of the cut-off component, and direction of the optical axes of the at least four LED light sources.
