A LIGHT MODULE FOR PRODUCING LIGHT WITH A SCATTERING PATTERN THAT IS ELECTRICALLY VARIABLE AND USE THEREOF AS MULTIPLE PURPOSE LIGHT

摘要

The invention provides a light module (1) arranged to produce a beam of light (25) with a scattering pattern that is electrically variable. The module comprises a light source (2) arranged to provide a beam of light (5); and an electrically adjustable optical element (300) arranged to adjust the beam of light (5) from light source (2). The adjustable optical element comprises a first cell (10) with a first liquid crystal gel (11); optionally a polarization rotator (30); a second cell (20) with a second liquid crystal gel (21); and a unit 40 for applying a voltage across at least one of the first and second cells (10,20). Especially, the light module (1) provides a beam of light (25) with an anisotropic light distribution.
