Abstract
A light assembly comprises a self-luminescent light source, a wave guide and output optics. The self-luminescent light source takes the form of a luminescent concentrator which is activated by beta radiation from tritium which is immobilized in a matrix in which a luminescent material is distributed.
Claims14
A luminescent concentrator light source, comprising:
- a matrix material,
- tritium immobilized to a carrier therefor and being distributed in said matrix material,
- a luminescent material activatable to generate electromagnetic radiation by beta radiation produced by said tritium and being distributed in said matrix material by being dissolved therein or immobilized to a carrier therefor, and
- an outer surface to said matrix material formed of a material which enhances internal reflection of electromagnetic radiation produced by said luminescent material.

A luminescent concentrator light source, comprising:
- a matrix material which is a transparent solid polymeric material,
- tritium chemically bound to said matrix material,
- a luminescent material activatable to generate electromagnetic radiation by beta radiation produced by said tritium and chemically bound to said matrix material, whereby said tritium and said luminescent material are distributed in said matrix material and are molecularly intermixed, and
- an outer surface of said matrix material formed of a material which enhances internal reflection of electromagnetic radiation produced by said luminescent material.
