Abstract: A luminaire for creating a uniform light pattern on an architectural surface, in the form of uniformly diminishing light with the distance from the light source. The luminaire includes a quasi point light source arranged vertically in the vicinity of an architectural surface, and a multi-zone refractor assembly radially surounding the light source and bending the light from the source toward the architectural surface. There is a reflector above the light source for reflecting light from the source toward the architectural surface. The refractor assembly may include a Fresnel lens, a lower refracting condenser ring, a toroidal reflector, or a conical reflecting surface. The uppermost zone of the refractor assembly can include a reflector structure which collects and projects 180 degrees of the light from the light source in the same radial zone as the reflector structure toward and onto an upper conical reflector, and the reflector structure can include a parabolic reflector and a conical reflector.

Abstract: A mechanical device that allows for changing a lamp that, when in its operating position, is surrounded by an optical system that is close to the lamp and therefore restricts access for lamp removal and accurate replacement within the optical system. This mechanical device may be used in any lighting product with or without an optical system to facilitate lamp/bulb changes. This mechanical device can be integrated into the structure of various lighting products such as table and floor lamps, ceiling fixtures and pendants, and outdoor poles. A lighting product which has been integrated with this lamp change device has the means to radiate light for desired illumination: a lamp (bulb) surrounded by said light radiator, said bulb is connected to a socket which is further connected to a socket mounting means.

Abstract: A light assembly including a central axis along which a light source is intended to be located. A ring lens at least partially surrounds the central axis, the lens having a central projection along a projection axis for projecting the light passing through the lens along the projection axis.

Another embodiment of the light assembly includes a central axis on which a light source is located and a ring lens at least partially surrounding the central axis. The lens is constructed and arranged to provide collimated light horizontally about a plane which is at a right angle to the central axis, and non-collimated light vertically and in directions which are perpendicular to tangents at the exit points of the rays from the lens.

Abstract: In a light distribution system for producing a series of light beams remote from a quasi point source, a light collection means, a conveyance means having an axis, and a series of illumination directors are provided. The light collection means projects light from the quasi point source through the conveyance means to the series of illumination directors. The illumination directors are axially displaced from one another, and each illumination director directs a beam away from the system to provide illumination. At least one of the illumination directors comprises a beam splitting reflector having a predetermined ratio of reflection to transmission. Consequently, each illumination director in the series provides a measured amount of brightness in a predetermined ratio to the other illumination directors in the series. The light collection means and said illumination directors define brightness and size of the beams projected from the system.

Abstract: A light distribution system for distributing beams at remote locations, light beams from a quasi point source includes means for collimating light from the source into a radial beam or beams, conveyance means carrying collimated beams to remote illumination directors for directing light from the light distribution system to a volume to be illuminated. Light loss due to changing the system from a first configuration, i.e. set of spatial location spatial locations of illumination directors, to a second configuration is substantially eliminated. Means are provided to manipulate light beams to control their diversion and continuity in response to movements from changing from the first configuration to the second.

Abstract: From a quasi point source, light distribution means produce a selected one or ones of broadly distributed ambient light, non-shadowing task illumination, multibeam display lighting, projective lineal lighting and projective surface washing illumination lineally or radially distributed. Collimation optics shape light from a quasi point source into a disc of selected axial thickness. Containment optics contain divergence of and direct light from the collimation optics to distribution optics. The distribution optics modulates and redirects the radiant energy into a shape or shapes useful in illuminating architectural space. The distribution optics may reflect or refract light to direct and shape it for a particular architectural illumination requirement. The efficient combination of the optics provides for a system of minimized thickness, permitting maximum flexibility in integration with or within shelves, soffits and other structural members.

The exit means each project light away from the conveyance means. The exit means are distributed at a number of locations at differing locations with respect to the source so that a lineal distribution of light from the source is provided.
