Abstract
An illumination module comprising a housing having one or more cavities, each containing a source of illumination such as an incandescent lamp at its closed end. A housing mounting plate containing a window coextensive with the open end of the housing is affixed to the open end of said housing in such a way as to create a slot between the mounting plate and the housing. A movable mask containing one or more apertures to configure and position the light as it leaves the housing through the window is located in the slot so that one or more segregated targets can be illuminated by means of the single mask positioning of the apertures relative to the open end of the individual cavities.
Claims18
An illumination module, comprising,
- (a) a housing having an opening at one end,
- (b) the housing having a housing mounting plate across the opening and spaced therefrom creating a slot in the housing adjacent to the housing mounting plate, the housing mounting plate having a window coextensive with the open end of said housing, the housing having means for inserting a mask in the as formed slot,
- (c) an illumination source at the closed end of said housing,
- (d) an insertable mask located within said slot, the mask having aperture means for configuring and positioning illumination from said source passing through the aperture means to a target area in the external environment.
An illumination module having means for providing segregated and targeted illumination with little or no spillover between adjacent target areas, comprising a housing having an opening at one end, a housing mounting plate having a window coextensive with the open end of said housing, said housing mounting plate being affixed across and spaced from said opening, creating an integrally formed slot between said mounting plate and said housing, an illumination source at the closed end of said housing, a mask having aperture means located within said slot for segregating, configuring and positioning illumination from said source passing through the aperture means to a plurality of target areas in the external environment with little or no spillover between adjacent target areas.
