Abstract: An optical emitting module includes a light-emitting device that emits light, and a lens member having a refracting surface configured to refract light emitted from the light-emitting device and to emit refracted light. The lens member is configured such that, when the angle of a light beam emitted from the lens member with respect to a principal light axis is ?1, a light beam with the maximum emission angle ?1 from the lens member is emitted from the refracting surface in the vicinity of a point where the refracting surface and the principal light axis cross each other. With this configuration, even when the light-emitting surface of a light source is large, it is possible to suppress the spread of emergent light from the lens member, obtaining a light intensity distribution with high uniformity.

Abstract: A lighting system for an indoor room or space is designed to provide a diffuse, glare free source that illuminates the room from the cornice, or a similar location around the join between the walls and ceiling. This may be achieved via a direct source of illumination at the cornice location, or by projecting illumination from a remote source. The lighting system is further designed to allow for illumination of certain areas of the cornice, and hence the room, whilst leaving other parts dark. There are multiple advantages of an adaptable system such as this, but in particular the lighting conditions can be adjusted for optimum lighting levels, for example dimming selected areas when viewing a television.
