A light fixture has a reflector having a part-elliptical surface and having at least one focal point at which is provided an LED set behind a main shield that prevents light from passing directly out of the light through a light-output plane. The reflector surface is shaped as an ellipse outside the apex point and adjacent the one focal point of the ellipse at which the LED is located. An arcuate portion of the ellipse segment defines the light-output plane, and the reflector surface extends along a longitudinal straight line. The LED, a straight longitudinally extending free edge of the main shield, and a straight longitudinally extending free edge of the reflector surface or a longitudinally extending straight edge of a secondary shield positioned generally at the outer free edge of the reflector surface lie in a common plane.

Reflector-type light fixture

A lamp assembly having a lens plate covering the opening and spaced from the lamp. The lens plate is provided with a multiplicity of microlenses such that the lens plate and lamp assembly generates a well defined light cone with a sharp demarcation between the dark region outside the light cone and the illuminated region within the light cone and the illumination within the light cone is homogeneous.

Lamp, especially for illuminating interiors

A parabolic reflector lighting fixture for use as an in-the-wall or in-the-floor or in-the-ceiling light has its lamp shiftable in a lumen plane perpendicular to the axis of symmetry of the parabolic reflector through the focal point. The parabolic reflector is limited to reflect light only between the intersection of this lumen plane and the reflector and between this intersection and the apex of the reflector.
