Abstract
A lamp comprising a light source (18) and a reflector (26), wherein the reflector is of non-circular cross-section perpendicular to the longitudinal axis of the lamp and comprises several panels (20). Each panel has an undulating surface (22) that diffuses the light and so provides a relatively uniform level of illumination. The reflector panels may be concave and preferably form a hexagonal or square section reflector that is closed by a transparent cover (24). The lamp is provided for use as a recessed ceiling light and is secured by a circlip (44) and a sprung bracket mount (30). Also disclosed is a lamp with a non-circular section reflector formed from concave reflector panels.
Claims15
A lamp comprising a light source, and a reflector for reflecting light emitted from the light source, the reflector having a non-circular section when viewed along a longitudinal axis of the lamp, wherein the reflector includes a series of reflection panels, the reflection panels forming the sides of a truncated pyramidal form, the number of sides of the pyramid equaling the number of panels, each reflection panel including a plurality of distinct elongate light reflection elements formed thereon, in which each reflection panel is generally outwardly concave in form towards the light source, characterized in that each light reflection element includes a front surface being convex toward the light surface, and wherein each reflection element extends in a direction perpendicular to the longitudinal axis of the lamp such that the sides of the pyramid are substantially flat when viewed in a cross-section perpendicular to the longitudinal axis of the lamp.
A light fitting including a lamp fitted thereto, the filling being adapted to be fitted to a layer of building material with the lamp substantially recessed, said lamp comprising a light source, and a reflector for reflecting light emitted from the light source, the reflector having a non-circular section when viewed along a longitudinal axis of the lamp, wherein the reflector includes a series of reflection panels, the reflection panels forming the sides of a truncated pyramidal form, the number of sides of the pyramid equaling the number of panels, each reflection panel including a plurality of distinct elongate light reflection elements formed thereon, in which each reflection panel is generally outwardly concave in form towards the light source, each light reflection element including a front surface being convex toward the light source, and wherein each reflection element extends in a direction perpendicular to the longitudinal axis of the lamp such that the sides of the pyramid are substantially flat when viewed in a cross-section perpendicular to the longitudinal axis of the lamp.
