Abstract:
The invention relates to a process for producing self-illuminating bodies (101..104), in which a recess (1) is made in a housing part (2, 3) of a housing and a fluorescent and/or phosphorescent layer (7) and/or a mask (9) is arranged on a boundary wall (12) of a cavity (5) which is formed by joining the housing parts (2, 3) together. The housing parts (2, 3) are connected in a gastight manner, with at least one feed opening (4) from outside into the cavity (5) remaining open. Furthermore, a medium (6) emitting decaying radiation is introduced through the at least one feed opening (4) into the cavity (5), the decaying radiation being intended to illuminate the fluorescent and/or phosphorescent layer (7). Furthermore, a self-illuminating body (101..104) and also the use thereof are specified.
Abstract:
The invention provides a nuclear battery comprising nanoparticles of a radioactive isotope mixed with an electroluminescent phosphor layer (42), and a photovoltaic cell (46) arranged to receive photons from the electroluminescent phosphor layer. Typically the isotope is an a or β emitter, such as Ni-63 or Am-241. This allows sealed long-life batteries to be produced.
Abstract:
A dielectric barrier discharge, DBD, lamp device comprises a toroid shaped discharge chamber (10) having a discharge chamber wall (12). The discharge chamber wall comprises a tubular inner wall section (14), a tubular outer wall section (16), and two ring-shaped end wall sections (18, 20). Each of the end wall sections extend between an end of the outer wall section and an end of the inner wall section. A high voltage electrode (22) is provided at an outer surface of the outer wall section of the discharge chamber wall. A low voltage electrode comprises an electrically conducting fluid surrounded by the inner wall section of the discharge chamber wall. The DBD lamp device may be part of an optical fluid treatment device.
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.
Abstract:
A light emitting device in which annular self luminous light sources are supported intermediate the ends of a resilient rod. In an illustrated embodiment a plurality of the rods are located concentrically within a transparent tube between end caps which close the ends of the tube.
