20080239727 | VENTED IRIS CONTROL FOR LUMINAIRE - Disclosed in this specification is a luminaire with a vented iris controller disposed on the external surface of the housing of the luminaire. The controller is for dilating and constricting the iris, thus controlling the size of the illuminated spot, wherein the iris controller is comprised of a hollow cylinder, rotatable relative to the housing. The cylinder has an inner ring and an outer ring, wherein the inner ring and outer ring are connected by a plurality of braces and vented spaces are present between each of the braces. Advantageously, the vented spaces help keep the outer ring cool, thus facilitating the operation of the iris controller by a user. | 10-02-2008 |
