An apparatus for illumination generating artificial light which resembles natural light as much as possible comprises a light source radiating substantially in the blue-green region, such as a fluorescent lamp (16a,b,c,d) and at least one incandescent lamp (18).

An apparatus for illumination generating artificial light which resembles natural light as much as possible comprises a light source radiating substantially in the blue-green region, such as a fluorescent lamp (16a,b,c,d) and at least one incandescent lamp (18). Prior to exiting from a housing (12) of the illumination equipment the light of the light source radiating blue-green is reflected at least once from a white wall (14). This applies also, in part at least, to the light of the incandescent lamp (18).

Illumination equipment for producing light closely resembling natural daylight, comprising: a housing having a reflective inner surface, an upper wall and an opening oppositely disposed from said upper wall; at least one light source radiating substantially in the blue-green region of the light spectrum positioned at a location within said housing at which radiation therefrom can exit from said opening only after having been reflected at least once from the reflective inner surface of said housing; and at least one light source radiating substantially in the red-orange-yellow region of the light spectrum positioned within said housing at a location at which a portion of the radiation therefrom exits directly from said opening without having been reflected from the reflective surface of the housing and a portion of the radiation therefrom is blended by reflection on the reflective inner surface of said housing with radiation from said at least one blue-green light source prior to exiting from said opening, whereby the light radiated from said opening is composed, at each radiation angle, of components which originate from said at least one blue-green light source and from said at least red-orange-yellow light source.
