Directable light
First Claim
1. A directable light, the light comprising:
- a light source for generating light;
a first reflector for forming said generated light into a beam;
a light switching layer, located between said light source and said first reflector such that said generated light travels through said light switching layer prior to being reflected by said first reflector, said light switching layer comprising a plurality of portions, each of said portions having at least two states, in a first state said light switching layer being substantially transparent to said generated light and in a second state said light switching layer being substantially opaque to said generated light; and
a light controller which determines which of said portions of said light switching layer are substantially transparent and which of said portions of said light switching layer are substantially opaque.

Abstract
A directable light, the light comprising: a light source for generating light; a first reflector for forming said generated light into a beam; a light switching layer, located between said light source and said first reflector, said light switching layer comprising a plurality of portions, each of said portions having at least two states, in a first state said light switching layer being substantially transparent to said generated light and in a second state said light switching layer being substantially opaque to said generated light; and a light controller which determines which of said portions of said light switching layer are substantially transparent and which of said portions of said light switching layer are substantially opaque.

8. A method of configuring the output of a light source in a vehicle, the method comprising:
-
providing a first reflector for forming the output of the light source into a beam, the first reflector located in directions contained within a hemisphere centered on the light source; providing a light switching layer, located between the light source and the first reflector such that generated light of the light source travels through the light switching layer prior to being reflected by the first reflector, the light switching layer comprising a plurality of portions, each portion having at least two states, in a first state being substantially transparent to the generated light and in a second state being substantially opaque to the generated light; and providing a light controller which determines which portions of the light switching layer are substantially transparent and which portions are substantially opaque. - View Dependent Claims (9, 10, 11, 12)
