1. A directional illumination source, comprising:
a directional housing extending from a base in a first direction, wherein the directional housing includes a first end connected to the base and a second end that is wider than the first end and spaced away from the first end, a plurality of LED illumination elements that are mounted proximate each other in a central cluster with respect to the housing opposite the base and leaving a peripheral space around the cluster, wherein the peripheral space is significantly larger than a separation between the LED illumination elements in the cluster, wherein an axis of illumination of each of the LED illumination elements faces at least generally in the first direction, a plurality of lens elements each aligned with an illumination axis of one of the LED illumination elements and wherein at least part of the peripheral space is outside of the direct illumination path of all of the LED illumination elements, a light-transmitting housing cover mounted with respect to the housing at the second end in front of an axis of illumination of the LED illumination elements, wherein the light-transmitting housing cover is mounted generally normal to the first direction and includes a light diffusive pattern in front of the peripheral space that is optically coupled to the LED illumination elements to distribute light around the diffusive pattern outside of the direct illumination path of all of the illumination elements when the illumination elements are on, and wherein the directional housing, the LED illumination elements, the lens elements, and the light-transmitting housing cover are part of a replacement PAR-type lamp. |
