A louver attachment for lights is constructed so that it is collapsible and portable to permit its use in a variety of applications wherein it is placed over the front of a light source to limit lateral distribution of the light. This configuration is advantageously used in connection with photographer's lighting systems. A framework is provided having two oppositely positioned parallel horizontal members having a series of openings along their lengths. A pair of parallel vertical side members connect corresponding ends of horizontal members together. The interconnections are allowed to pivot so that the parallelogram shaped structure may be collapsed. A wide ribbon is then woven between the horizontal members passing through the openings to form louvers. The ribbon is secured at either end to the framework. Conventional methods of attachment serve to attach the louver attachment over the front of a light source. One form of the louver attachment consists of a pair of rigid ladder-like horizontal members connected together by a pair of rigid, vertical side members. The ribbon is woven between the rungs of the ladder-like members having their respective rungs so spaced as to form parallel and equally spaced louvers.
