Abstract
An arrangement (1) for forming into a luminaire, the arrangement (1) comprising: one or more optical cells (10) each including means for receiving, collecting and redistributing light from a respective one of one or more light sources (32), e.g. LEDs; and a configuring element (20) for accommodating the one or more optical cells (10) in a predefined relative configuration or pattern; wherein the configuring element (20) comprises a sheet or plate or film of material having one or more apertures (22) therein in the said predefined relative configuration or pattern, each aperture (22) being for receiving therein a respective one of the said cells (10).
Claims21
An arrangement for forming into a luminaire, the arrangement comprising:
- one or more optical cells configured for receiving, collecting and redistributing light from a respective one of one or more light sources;
- and
- a configuring element for accommodating the one or more optical cells in a predefined relative configuration or pattern,
- wherein:
- the configuring element comprises a sheet or plate or film of material having one or more apertures therein in the predefined relative configuration or pattern, each aperture being configured for receiving therein, or being configured for and having received therein, a respective one of the optical cells;
- the one or more optical cells each comprises:
- a light collector element;
- a cover element attached to the light collector element;
- and
- a transmission element mounted between the light collector element and the cover element;
- the light collector element comprises a body including:
- an input for receiving and collecting light from at least one light source;
- an output for propagating collected light towards the transmission element;
- at least one wall defining one or more portions of the body between its input and output and configured for collecting light entering the body via its input and conveying or directing the light towards its output;
- and
- an attachment for mechanically attaching the body of the light collector element to the cover element and securing the transmission element between the light collector element and the cover element;
- the cover element comprises:
- an input opening facing towards the transmission element and for receiving light transmitted by the transmission element;
- an output opening via which light is outputted from the optical cell;
- and
- at least one internal surface defining a cavity within the cover element between its input and output openings, the cavity's internal surface(s) being configured for allowing or effecting passage of light, or a portion of the light, through the cavity from the cover element's input opening towards its output opening;
- and
- the transmission element comprises one or more planar optical elements;
- the one or more optical elements each includes a first surface facing towards the output of the light collector element and a second surface facing towards the input opening of the cover element;
- and
- the one or more optical elements each exhibits a predetermined optical activity or function in its transmission of light incident thereon which has exited the output of the light collector element and is transmitted by the transmission element towards the input opening of the cover element.
