Title:
A lighting installation for obtaining predetermined Light distribution in target area
Document Type and Number:
Japanese Patent JP6275129
Kind Code:
B2
Abstract:
The invention relates to a lighting device (100) comprising a light source (110) and an optical component (120) adapted for obtaining a predetermined light distribution (300) at a target area (400). The optical component has a substrate (122) comprising a material that is capable of controllably changing shape when an activating force is applied thereto, and one or more optical elements (121). The substrate further comprises a material capable of being switched from a first state comprising a first static modulus to a second state comprising a second static modulus by means of an external stimulus (140), the first static modulus being smaller than the second static modulus, the static modulus being calculated as the ratio of strain to stress of the substrate under static conditions. This material is capable of controllably changing shape in the first state and being dimensionally stable in the second state, when no activating force is applied thereto.
