Abstract
A light fixture for illuminating building surfaces or partial surfaces of a building has a housing, a light source on the housing, a focusing optical unit on the housing and separate from the light source for focusing and projecting light emitted by the light source in a direction, a first lens plate in the light path spaced a first distance downstream in the direction of the focusing optical unit, the first lens plate having a plurality of first lenticular lenses arranged thereon, a second lens plate receiving light from the first lens plate and spaced a second distance downstream in the direction from the first lens plate, the second lens plate having a plurality of second lenticular lenses arranged thereon. Each of at least some of the first lenticular lenses is aligned in the direction with a respective second lenticular lens.

A light fixture for illuminating building surfaces or partial surfaces of a building, the light fixture comprising:
- a housing,
- a light source on the housing,
- a focusing optical unit on the housing and separate from the light source for focusing and projecting light emitted by the light source in a direction,
- a first lens plate in the light path spaced a first distance downstream in the direction of the focusing optical unit, the first lens plate having a plurality of first lenticular lenses arranged thereon,
- a second lens plate receiving light from the first lens plate and spaced a second distance downstream in the direction from the first lens plate, the second lens plate having a plurality of second lenticular lenses arranged thereon,
- wherein each of at least some of the first lenticular lenses aligned in the direction with a respective second lenticular lens, each first lenticular lens receiving parallel light from the optical unit and focusing all of the received light on the respective second lenticular lens, and
- an adjusting device for varying at least the second distance such that the light fixture provides different light distributions in different relative spacings of the lens plates, wherein at least one second distance is provided wherein the light emanating from the first lenticular lens is to focus in a focal area between the first lens plate and the second lens plate.
A light fixture for illuminating building surfaces or partial surfaces of a building, the light fixture comprising:
- a housing,
- a light source on the housing,
- a focusing optical unit on the housing and separate from the light source for focusing and projecting light emitted by the light source in a direction,
- a first lens plate in the light path spaced a first distance downstream in the direction of the focusing optical unit,
- a second lens plate receiving light from the first lens plate and spaced a second distance downstream in the direction from the first lens plate,
- respective pluralities of first lenticular lenses and second lenticular lenses on the lens plates with each of at least some of the first lenticular lenses aligned in the direction with a respective second lenticular lens, each first lenticular lens receiving parallel light from the optical unit and focusing all of the received light on the respective second lenticular lens, and
- an adjusting device for varying at least the second distance such that the light fixture provides different light distributions in different relative spacings of the lens plates, the adjusting device having a manually actuatable adjusting element on the housing for altering the spacing, wherein at least one second distance is provided wherein the light emanating from the first lenticular lens is to focus in a focal area between the first lens plate and the second lens plate.
A light fixture for illuminating building surfaces or partial surfaces of a building, the light fixture comprising:
- a housing,
- a light source on the housing,
- a focusing optical unit on the housing and separate from the light source for focusing and projecting light emitted by the light source in a direction,
- a first lens plate in the light path on the housing and spaced a first distance downstream in the direction from the optical unit,
- a second lens plate receiving light from the first lens plate and spaced a second distance downstream in the direction from the first lens plate,
- respective pluralities of first and second lenticular lenses on the lens plates and each lens plate having on a face of the respective lens plate a plurality of lenticular lenses, each of at least some of the first lenticular lenses being aligned in the direction with a respective second lenticular lens to receive parallel light from the optical unit and focus all of the received light in the direction on the respective second lenticular lens, and
- an adjusting device for varying at least the second distance between the first and second lens plates such that the light fixture provides different light distributions in different relative spacings of the lens plates.
