Abstract
The invention relates to a portable electric lamp with a light source generating at least one light beam; and a pane of glass arranged in front of the light source. The pane of glass has an electro-optical diffusion device controlled by an electrical signal in order to generate electrically adjustable diffusion. This diffusion generates a light beam with variable geometry from the single narrow beam. This results in headlamps with improved control of the geometry of its lightbeams.
Claims26
A portable electric lamp comprising:
- a light source generating at least one light beam;
- and
- a panel disposed in front of said light source, said panel comprising an electro-optical device driven by an electric signal for producing an electrically adjustable diffusion, so as to generate a light beam having a variable geometry from the single narrow beam.
A method of providing a portable electric lamp comprising the steps of:
- generating at least one light beam with a light source;
- and
- producing an electrically adjustable diffusion with a panel disposed in front of said light source, said panel comprising an electro-optical device driven by an electric signal, so as to generate a light beam having a variable geometry from the single narrow beam.
