摘要:
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.

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.

A process produces self-illuminating bodies, in which a recess is made in a housing part of a housing and a fluorescent and/or phosphorescent layer and/or a mask is arranged on a boundary wall of a cavity which is formed by joining the housing parts together. The housing parts are connected in a gastight manner, with at least one feed opening from outside into the cavity remaining open. Furthermore, a medium emitting decaying radiation is introduced through the at least one feed opening into the cavity, the decaying radiation being intended to illuminate the fluorescent and/or phosphorescent layer. Furthermore, a self-illuminating body and also the use thereof are specified.

An example optic module verification device for use in periodic normalization of a testing machine used to test samples in wells is disclosed. The example testing machine includes a plurality of photon counters that each count photons emitted from different wells. The example verification device includes a plurality of verification wells located so as to each be associated with one of the photon counters when used in the testing machine. The example device also includes a photon emitter in each verification well, each photon emitter including a C14 source, a scintillator adjacent the C14 source, and a filter over the scintillator. The example photon emitters each have a determined initial base value for emitted photons, and each photon emitter is positioned in its verification well to emit photons through the filter to the associated photon counter when used in the testing machine.

An optic module verification device for normalizing between X photon counters, including a verification tray with X verification wells and a modular photon emitter in each verification well. Each photon emitter includes a spring, a Beta source disk, a scintillator disk adjacent the Beta source disk, and a neutral density filter over the scintillator disk, all of which are encapsulated in a cylindrical chamber with the filter adjacent an opening on one end of the chamber and the spring biasing the Beta source disk and the scintillator disk toward the opening. The device is periodically used for normalization, and may be updated when emitted photons fall below a desired level by replacing the scintillator disk and then determining a new normalized reference values for each photon emitter.

There is disclosed a self-luminous source of light preferably as applied to illuminated signs and safety markers which emits a high level of uniform light. The invention utilizes a beta emitter, preferably tritium gas, which is contained within a sealed glass enclosure having an interior coating of a phosphor. The glass enclosure is contained within an outer enclosure formed of a plastic filled with a fluorescent dye. The phosphor coating on the glass enclosure of the tritium gas absorbs beta radiation from the tritium and emits radiation in a wavelength approximately 360 nanometers which excites the fluorescent dye in the plastic outer enclosure.
摘要:
A self-luminous light source is disclosed having a light-permeable shell, a body disposed within the shell, defining a space between the shell and body, a member connecting the shell and body, radioactive gas disposed in the space, and a phosphor coating on at least one surface of the shell and body. The shell and body may be coaxial glass tubes defining an annular space of restricted width, connected to one another by annular end members.
