摘要： A lens for a primarily-elongate distribution of light from a light emitter having an axis with a lens base being substantially normal to the axis. The lens includes a substantially-rectangular emitter opening to a cavity defined by a refracting inner surface. The lens further includes a refracting main output surface transverse the axis and a reflecting surface extending from the lens base away from the axis outwardly of and around the inner surface. The reflecting surface receives substantially all forward and rearward light and a portion of lateral light refracted by the inner surface for total internal reflection (TIR) toward the main output surface which refracts such light into the elongate distribution. The lens is configured such that the other portion of the lateral light exits the lens away from the axis for wide-angle distribution along the elongate distribution.

摘要： A lens for distribution of light from a light emitter having an axis, the lens including a (1) base forming a substantially rectangular opening to an emitter cavity defined by an inner surface, (2) a main output surface transverse the axis, (3) a reflecting surface is positioned to reflect light received from the inner surface toward the main output surface, the reflecting surface including front and back curvatures and a pair of substantially-identical lateral curvatures each adjoining the front and back curvatures. Configuration of the lateral curvatures differs from configurations of the front and back curvatures, which differ from one another.

摘要： A recessed lighting fixture for mounting into a structure facing an illumination area. The fixture includes a support member configured for mounting into the structure and including a front end-portion having an edge defining a light opening and a back end-portion recessed from the opening. The support member and opening have a centerline. A mounting board is disposed at the back end-portion and defines with the support member an open space extending to the opening. An LED arrangement includes (a) LED emitter(s) on the mounting board for directing light toward the opening, each emitter defining an emitter axis, and (b) a lens for each emitter at least one of which is off-centerline in a first lateral direction. The lens is configured for distribution of emitter light in off-axial direction across the open space and passing through the opening at an edge portion that is off-centerline in the opposite lateral direction, thereby to widen the illumination angle from the fixture while having no more than minimal light directed onto the support member.
