A signal element without a lamp for use with signal buttons, toggle switches, control knobs, slide switches and the like which has a moveable member received in the housing member for movement between at least two positions to cause actuation of the part of the element characterized by a fluorescent member consisting of a body of material having an index of refraction >1 and containing fluorescent particles for fluorescently collecting and scattering incident light to create fluorescent light and means for uncoupling concentrated fluorescent light from the fluorescent member to a point of the element in response to a selected position of the moveable member in the housing member. The moveable member may be a push button, a pivotable rocking member or a slide and the fluorescent member may be carried by the moveable member or may be part of the housing, which receives the moveable member.
In a signal element without a lamp having a moveable member received in a housing member for movement between at least two positions to cause actuation of parts of said element, the improvement comprising one of said housing and moveable members including a fluorescent member consisting of a body of material having an index of refraction >1 and containing fluorescent particles for fluorescently collecting and scattering incident light to create fluorescent light, and means for uncoupling concentrated fluorescent light from the fluorescent member to a point of the element in response to a selected position of the moveable member in the housing member.
In a signal element without a lamp having a moveable member received in a housing member for movement between at least two positions to cause actuation of parts of said element, the improvement comprising a fluorescent member consisting of a body of material having an index of refraction >1 and containing fluorescent particles for fluorescently collecting and scattering incident light to create fluorescent light, said fluorescent member being integral with the moveable member of the signal element, and means for uncoupling concentrated fluorescent light from the fluorescent member to a point of the element in response to a selected position of the moveable member in the housing member.
In a signal element without a lamp having a moveable member received in a housing member for movement between at least two positions to cause actuation of parts of said elements, the improvement comprising the moveable member rotating in a housing member having light impermeable portions and light permeable portions, a fluorescent member consisting of a body of material having an index of refraction >1 and containing fluorescent particles for fluorescently collecting and scattering incident light to create fluorescent light, said fluorescent member including at least one curved member carried by the moveable member for rotation between a position adjacent a light impermeable portion of the housing member and a light transmitting portion, and means for uncoupling concentrated fluorescent light from the fluorescent member and directing the fluorescent light to a coupling out point on the moveable member in response to a selected position of the moveable member in the housing member.
In a signal element without a lamp having a moveable member received in a housing member for movement between at least two positions to cause actuation of parts of said element, the improvement comprising a fluorescent member consisting of a body of material having an index of refraction >1 and containing fluorescent particles for fluorescently collecting and scattering incident light to create fluorescent light, said fluorescent member being a part of the housing member and forming a part of an outer surface of the housing member, and means for uncoupling concentrated fluorescent light from the fluorescent member to a point of the element in response to a selected position of the moveable member in the housing member.
